  • Why is there a /etc/init.d/mysql file on this Slackware machine? How could it have gotten there?

    - by jasonspiro
    A client of my IT-consulting service owns a web-development shop. He's been having problems with a Slackware 12.0 server running MySQL 5.0.67. The machine was set up by the client's sysadmin, who left on bad terms. My client no longer employs a sysadmin. As far as I can tell, the only copy of MySQL that's installed is the one described in /var/log/packages/mysql-5.0.67-i486-1: PACKAGE NAME: mysql-5.0.67-i486-1 COMPRESSED PACKAGE SIZE: 16828 K UNCOMPRESSED PACKAGE SIZE: 33840 K PACKAGE LOCATION: /var/slapt-get/archives/./slackware/ap/mysql-5.0.67-i486-1.tgz PACKAGE DESCRIPTION: mysql: mysql (SQL-based relational database server) mysql: mysql: MySQL is a fast, multi-threaded, multi-user, and robust SQL mysql: (Structured Query Language) database server.

Their home directory was /root. I've pasted a copy at http://www.pastebin.ca/2167496. My question: Why is there a /etc/init.d/mysql file on this Slackware machine? How could it have gotten there? P.S. This question is far from perfect. Please feel free to edit it.

  • SQL Server Licensing in a VMware vSphere Cluster

    - by Helvick
    If I have SQL Server 2008 instances running in virtual machines on a VMware vSphere cluster with vMotion\DRS enabled so that the VM's can (potentially) run on any one of the physical servers in the cluster what precisely are the license requirements? For example assume that I have 4 physical ESX Hosts with dual physical CPU's and 3 separate single vCPU Virtual Machines running SQL Server 2008 running in that cluster. How many SQL Standard Processor licenses would I need? Is it 3 (one per VM) or 12 (one per VM on each physical host) or something else? How many SQL Enterprise Processor licenses would I need? Is it 3 (one per VM) or 8 (one for each physical CPU in the cluster) or, again, something else? The range in the list prices for these options goes from $17k to $200k so getting it right is quite important. Bonus question: If I choose the Server+CAL licensing model do I need to buy multiple Server instance licenses for each of the ESX hosts (so 12 copies of the SQL Server Standard server license so that there are enough licenses on each host to run all VM's) or again can I just license the VM and what difference would using Enterprise per server licensing make? Edited to Add Having spent some time reading the SQL 2008 Licensing Guide (63 Pages! Includes Maps!*) I've come across this: • Under the Server/CAL model, you may run unlimited instances of SQL Server 2008 Enterprise within the server farm, and move those instances freely, as long as those instances are not running on more servers than the number of licenses assigned to the server farm. • Under the Per Processor model, you effectively count the greatest number of physical processors that may support running instances of SQL Server 2008 Enterprise at any one time across the server farm and assign that number of Processor licenses And earlier: ..For SQL Server, these rule changes apply to SQL Server 2008 Enterprise only. By my reading this means that for my 3 VM's I only need 3 SQL 2008 Enterprise Processor Licenses or one copy of Server Enterprise + CALs for the cluster.

  • SQL Server Licensing in a VMware vSphere Cluster

    - by Helvick
    If I have SQL Server 2008 instances running in virtual machines on a VMware vSphere cluster with vMotion\DRS enabled so that the VM's can (potentially) run on any one of the physical servers in the cluster what precisely are the license requirements? For example assume that I have 4 physical ESX Hosts with dual physical CPU's and 3 separate single vCPU Virtual Machines running SQL Server 2008 running in that cluster. How many SQL Standard Processor licenses would I need? Is it 3 (one per VM) or 12 (one per VM on each physical host) or something else? How many SQL Enterprise Processor licenses would I need? Is it 3 (one per VM) or 8 (one for each physical CPU in the cluster) or, again, something else? The range in the list prices for these options goes from $17k to $200k so getting it right is quite important. Bonus question: If I choose the Server+CAL licensing model do I need to buy multiple Server instance licenses for each of the ESX hosts (so 12 copies of the SQL Server Standard server license so that there are enough licenses on each host to run all VM's) or again can I just license the VM and what difference would using Enterprise per server licensing make? Edited to Add Having spent some time reading the SQL 2008 Licensing Guide (63 Pages! Includes Maps!*) I've come across this: • Under the Server/CAL model, you may run unlimited instances of SQL Server 2008 Enterprise within the server farm, and move those instances freely, as long as those instances are not running on more servers than the number of licenses assigned to the server farm. • Under the Per Processor model, you effectively count the greatest number of physical processors that may support running instances of SQL Server 2008 Enterprise at any one time across the server farm and assign that number of Processor licenses And earlier: ..For SQL Server, these rule changes apply to SQL Server 2008 Enterprise only. By my reading this means that for my 3 VM's I only need 3 SQL 2008 Enterprise Processor Licenses or one copy of Server Enterprise + CALs for the cluster. By implication it means that I have to license all processors if I choose SQL 2008 Standard Processor licensing or that I have to buy a copy of SQL Server 2008 Standard for each ESX host if I choose to use CALs. *There is a map to demonstrate that a Server Farm cannot extend across an area broader than 3 timezones unless it's in the European Free Trade Area, I wasn't expecting that when I started reading it.

  • Ubuntu - Ruby Daemon script creates two processes - sh and ruby - PID file points at sh, not ruby

    - by Jonathan Scoles
    The PID file for a ruby process I have running as a daemon is getting the wrong PID. It appears that running /etc/init.d/sinatra start creates two processes - sh and ruby, and the PID that ends up in the PID file is that of the sh process. This means that when I then run /etc/init.d/sinatra stop or /etc/init.d/sinatra restart, it is killing sh and leaving the ruby process still running. I'd like to know a) why is my script launching two processes - sh and ruby, and not just ruby, and b) how do I fix it to just launch ruby? Details of the setup: I have a small Sinatra server set up on an ubuntu server, running as a daemon. It is set to automatically at server startup run a script named sinatra in /etc/init.d that launches the a control script control.rb, which then runs a ruby daemon command to start the server. The script is run under the 'sinatrauser' account, which has permissions for the directories the script needs. contents of /etc/init.d/sinatra #!/bin/bash # sinatra Startup script for Sinatra server. sudo -u sinatrauser ruby /var/www/sinatra/control.rb $1 RETVAL=$? exit $RETVAL To install this script, I simply copied it to /etc/init.d/ and ran sudo update-rc.d sinatra defaults contents of /var/www/sinatra/control.rb require 'rubygems' require 'daemons' pwd = Dir.pwd Daemons.run_proc('sinatraserver.rb', {:dir_mode => :normal, :dir => "/opt/pids/sinatra"}) do Dir.chdir(pwd) exec 'ruby /var/www/sinatra/sintraserver.rb >> /var/log/sinatra/sinatraOutput.log 2>&1' end portion of output from ps -A 6967 ? 00:00:00 apache2 10181 ? 00:00:00 sh <--- PID file gets this PID 10182 ? 00:00:02 ruby <--- Actual ruby process running Sinatra 12172 ? 00:00:00 sshd The PID file gets created in /opt/pids/sinatra/sinatraserver.rb.pid, and always contains the PID of the sh instance, which is always one less than the PID of the ruby process EDIT: I tried micke's solution, but it had no effect on the behavior I am seeing. This is the output from ps -A f. This output looks the same whether I use sudo -u sinatrauser ... or su sinatrauser -c ... in the service start script in /etc/init.d. 1146 ? S 0:00 sh -c ruby /var/www/sinatra/sinatraserver.rb >> /var/log/sinatra/sinatraOutput.log 2>&1 1147 ? S 0:00 \_ ruby /var/www/sinatra/sinatraserver.rb

  • Why is my cron daemon is being killed every few minutes? OpenVZ?

    - by user113215
    As of about a week ago, my cron daemon refuses to stay running. I'm using Debian 6. Running something like pgrep cron shows that the daemon isn't running. I start the service with service cron start or /etc/init.d/cron start and it launches, but it disappears from the running process list after a few minutes (varying anywhere between 1 - 30 minutes before the process is killed again). Using strace -f service cron start, I can see that the process is being killed for some reason: nanosleep({56, 0}, 0x7fffa7184c80) = 0 stat("crontabs", {st_mode=S_IFDIR|S_ISVTX|0730, st_size=4096, ...}) = 0 stat("/etc/crontab", {st_mode=S_IFREG|0644, st_size=1100, ...}) = 0 stat("/etc/cron.d", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0 stat("/etc/cron.d/php5", {st_mode=S_IFREG|0644, st_size=475, ...}) = 0 stat("/etc/cron.d/anacron", {st_mode=S_IFREG|0644, st_size=244, ...}) = 0 rt_sigprocmask(SIG_BLOCK, [CHLD], [], 8) = 0 rt_sigaction(SIGCHLD, NULL, {0x4036f0, [CHLD], SA_RESTORER|SA_RESTART, 0x2b0e8465f230}, 8) = 0 rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0 nanosleep({60, 0}, <unfinished ...> +++ killed by SIGKILL +++ There's nothing relevant in /var/log/syslog, /var/log/messages, /var/log/auth.log, or /var/log/kern.log to explain why the the process is dying. The system has about 500 MB of free memory, and cat /proc/loadavg returns 0.10 0.21 0.45 so resources shouldn't be the issue. I also tried removing and reinstalling the cron package using apt-get. What else should I check? How do I find out what's killing my crond? Edit: I'm on a virtual machine under OpenVZ (and as such, I have no swap).

  • How to configure nginx so it works with Express?

    - by Michal Stefanow
    I'm trying to configure nginx so it proxy_pass requests to my node apps. Question on StackOverflow got many upvotes: http://stackoverflow.com/questions/5009324/node-js-nginx-and-now and I'm using config from there. (but since question is about server configuration it is supposed to be on ServerFault) Here is the nginx configuration: server { listen 80; listen [::]:80; root /var/www/services.stefanow.net/public_html; index index.html index.htm; server_name services.stefanow.net; location / { try_files $uri $uri/ =404; } location /test-express { proxy_pass http://127.0.0.1:3002; } location /test-http { proxy_pass http://127.0.0.1:3003; } } Using plain node: var http = require('http'); http.createServer(function (req, res) { res.writeHead(200, {'Content-Type': 'text/plain'}); res.end('Hello World\n'); }).listen(3003, '127.0.0.1'); console.log('Server running at http://127.0.0.1:3003/'); It works! Check: http://services.stefanow.net/test-http Using express: var express = require('express'); var app = express(); // app.get('/', function(req, res) { res.redirect('/index.html'); }); app.get('/index.html', function(req, res) { res.send("blah blah index.html"); }); app.listen(3002, "127.0.0.1"); console.log('Server running at http://127.0.0.1:3002/'); It doesn't work :( See: http://services.stefanow.net/test-express I know that something is going on. a) test-express is NOT running b) text-express is running (and I can confirm it is running via command line while ssh on the server) root@stefanow:~# service nginx restart * Restarting nginx nginx [ OK ] root@stefanow:~# curl localhost:3002 Moved Temporarily. Redirecting to /index.html root@stefanow:~# curl localhost:3002/index.html blah blah index.html I tried setting headers as described here: http://www.nginxtips.com/how-to-setup-nginx-as-proxy-for-nodejs/ (still doesn't work) proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; proxy_set_header X-NginX-Proxy true; I also tried replacing '127.0.0.1' with 'localhost' and vice versa Please advise. I'm pretty sure I miss some obvious detail and I would like to learn more. Thank you.

  • DNS and DHCP dies after ~2 days of use on ClearOS

    - by TheLQ
    I'm using ClearOS (based on CentOS, so any info specific to it should apply here) as a gateway, DHCP, and DNS server. I had this server running perfectly for a month or two before replacing it with another server. However due DNS and DHCP failing 2 days in and a host of other performance issues (the box was a little underpowered), I changed back to the origional server. However 2 days in DHCP and DNS are failing again, and I'm out of idea's on why. In both cases to my knowledge no network or server changes occurred after installation. Right after installing (and at least a day in) DNS and DHCP was working just fine. However later (Day 2) I get a call saying their internet is down (translation: Nobody can get to websites because DNS is down) I've tried to fix the problem by checking if the dnsmasq is even running (it is), restarting the service, and restarting the server to no effect. I do have two internal servers that have static DHCP leases but one's lease must of expired as I can't connect to it anymore. I'm hesitant to do any dhcp testing on the last server as I'll not be able to connect to it anymore. Is there anything anyone can think of on why DNS and DHCP would fail 2 days in to running perfectly? More info: Running dnsmasq in debug mode. This is all that's displayed even when running nslookup quackwall. I'm not sure though if nslookup commands should show up in the log [root@quackwall ~]# /usr/sbin/dnsmasq -dq dnsmasq: started, version 2.49 cachesize 150 dnsmasq: compile time options: IPv6 GNU-getopt no-DBus no-I18N DHCP TFTP dnsmasq-dhcp: DHCP, IP range 10.0.0.100 -- 10.0.0.254, lease time 12h dnsmasq: reading /etc/resolv.conf dnsmasq: using nameserver 74.128.17.114#53 dnsmasq: using nameserver 74.128.19.102#53 dnsmasq: read /etc/hosts - 5 addresses dnsmasq-dhcp: read /etc/ethers - 2 addresses On the other server DNS and the Gateway are all configured correctly (10.0.0.2 is quackwall) lordquackstar@quackgame:~$ netstat -rn Kernel IP routing table Destination Gateway Genmask Flags MSS Window irtt Iface 10.0.0.0 0.0.0.0 255.255.240.0 U 0 0 0 eth0 0.0.0.0 10.0.0.2 0.0.0.0 UG 0 0 0 eth0 lordquackstar@quackgame:~$ cat /etc/resolv.conf nameserver 10.0.0.2 domain highwow.lan search highwow.lan

  • IIS 401.3 - Unauthorized on only 1 server out of 3 set up for network load balancing

    - by Tony
    Over the weekend our Server Admin set up two virtual Windows 2008 machines with IIS installed and set them up under NLB. I came in and changed the application pool the website was running under to our domain account that has proper access to the database and the file share hosting our .NET web application Sitefinity, and changed it to .NET 4 Integrated. NLB and everything was running fine on both servers. He brought up the third server for our cluster on Tuesday and I performed the same actions.. The only difference was that I was given admin rights for the third server so I could set it up remotely instead of going to his office. He has full control over the share and NTFS perms on \\hostname\Sitefinity and I believe I only had read access. I pointed the web site to the same \\hostname\Sitefinity\sitename share that the others were on and the authentication/authorization test settings passed. I hit the site from http://localhost (like I did successfully from the other two before trying the cluster's IP address) and I received a HTTP Error 401.3 - Unauthorized. I've verified many times that the application pool is running under the same service account. I tried hitting just a simple test.htm.. works fine on both of the first two servers but I get the same 401.3 on the third. I copied my dev project to the local inetpub directory and re-pointed the website and that ran perfectly. I turned on Failed Request Tracing and it acts like it's still running the local IUSR account I guess (instead of my domain account)? Here is an excerpt of the File Cache Access Start and the error from the trace: FileName \\hostname\sitefinity\sitename\test.htm UserName IUSR DomainName NT AUTHORITY ---------- Successful false FileFromCache false FileAddedToCache false FileDirmoned true LastModCheckErrorIgnored true ErrorCode 2147942405 LastModifiedTime ErrorCode Access is denied. (0x80070005) ---------- ModuleName IIS Web Core Notification 2 HttpStatus 401 HttpReason Unauthorized HttpSubStatus 3 ErrorCode 2147942405 ConfigExceptionInfo Notification AUTHENTICATE_REQUEST ErrorCode Access is denied. (0x80070005) ---------- My personal AD account was then granted read/write perms to the share so I created a new application pool and set the site under it in case there was an issue with the application pool but no success. I created another under my own account and it still failed. It just seems like maybe it's not trying to access the files under the account my application pools are running under although that's the only way I've done things before. I set the Physicial Path Credentials in Advanced Settings on the site to the service account and it threw a 500 error of some sort so I assume that's not the answer (and I don't have to do it on the other servers). It's like somehow I'm trying to force impersonation on the IUSR account or something?

  • Legacy VB6 application under Win7 SQL error

    - by Shial
    We have a rather unfortunate legacy application at work, written originally in VB6 it predates anybody in our IT department by at least 5 years. We have a contracted developer for ongoing maintenance and where he can he rewrites sections over into .NET code (Not sure about his techniques here, this is a side job for his regular work as an IBM engineer) the application works fine (such as it is) under windows XP. We have only a couple of Windows 7 machines mainly for testing and this application seems to run into a wall. Things like the background not loading and SQL errors. This is even running under administrator. Running an SQL trace from the ODBC control panel shows several interesting things. It makes a connection to the database successfully initially where it runs a query to determine if it is running the correct version. This query works fine. 558-1af0 ENTER SQLExecDirectW HSTMT 0x020D7548 WCHAR * 0x04C8F0F0 [ 115] "SELECT count(*) c FROM tblSoftwareVersion WHERE fldSoftwareVersion = '123456' AND fldSoftwareName = 'Application.VB'" SDWORD 115 BMS 558-1af0 EXIT SQLExecDirectW with return code 1 (SQL_SUCCESS_WITH_INFO) HSTMT 0x020D7548 WCHAR * 0x04C8F0F0 [ 115] "SELECT count(*) c FROM tblSoftwareVersion WHERE fldSoftwareVersion = '123456' AND fldSoftwareName = 'Application.VB'" SDWORD 115 It then seems to drop its connection and can't find the ODBC connection despite the fact its connecting to the same DB. From the trace it looks like it configures the connection then it starts firing off SQLFreeStmt to unbind and close out then when in the application and it tries to do its thing there is no connection. 558-1af0 ENTER SQLFreeStmt HSTMT 0x020D7548 UWORD 2 <SQL_UNBIND> BMS 558-1af0 EXIT SQLFreeStmt with return code 0 (SQL_SUCCESS) HSTMT 0x020D7548 UWORD 2 <SQL_UNBIND> Then this happens when I try to do something that pulls data 558-1af0 ENTER SQLDriverConnectW HDBC 0x020DDA00 HWND 0x00000000 WCHAR * 0x73EF8634 [ -3] "******\ 0" SWORD -3 WCHAR * 0x73EF8634 SWORD -3 SWORD * 0x00000000 UWORD 0 <SQL_DRIVER_NOPROMPT> BMS 558-1af0 EXIT SQLDriverConnectW with return code -1 (SQL_ERROR) HDBC 0x020DDA00 HWND 0x00000000 WCHAR * 0x73EF8634 [ -3] "******\ 0" SWORD -3 WCHAR * 0x73EF8634 SWORD -3 SWORD * 0x00000000 UWORD 0 <SQL_DRIVER_NOPROMPT> DIAG [IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified (0) Nearly all of my searching on this issue comes up with programming issues where the connection string has a problem. The only thing that is different in this particular scenario though is Windows 7, I know the connection string is fine since it works on the XP machines. The VB components are supposed to be still functional under Win7. My computer is running 32 bit win7 and my VP is running Win7 64 bit and both have the same problem so that can be ruled out. I have already tried reinstalling the SQL Native Client and the VB runtime as well as the application in question. Hopefully I can find a solution and not have to resort to using the XP VM.

  • Open a terminal window & run command, then close the terminal window if command completed successfully?

    - by Caspar
    I'm trying to write a script to do the following: Open a terminal window which runs a long running command (Ideally) move the terminal window to the top left corner of the screen using xdotool Close the terminal window only if the long running command exited with a zero return code To put it in Windows terms, I'd like to have the Linux equivalent of start cmd /c long_running_cmd if long_running_cmd succeeds, and do the equivalent of start cmd /k long_running_cmd if it fails. What I have so far is a script which starts xterm with a given command, and then moves the window as desired: #!/bin/bash # open a new terminal window in the background with the long running command xterm -e ~/bin/launcher.sh ./long_running_cmd & # move the terminal window (requires window process to be in background) sleep 1 xdotool search --name launcher.sh windowmove 0 0 And ~/bin/launcher.sh is intended to run whatever is passed as a command line argument to it: #!/bin/bash # execute command line arguments $@ But, I haven't been able to get the xterm window to close after long_running_cmd is done. I think something like xterm -e ~/bin/launcher.sh "./long_running_cmd && kill $PPID" & might be what I'm after, so that xterm is launched in the background and it runs ./long_running_cmd && kill $PPID. So the shell in the xterm window then runs the long running command and if it completes successfully, the parent process of the shell (i.e. the process owning the xterm window) is killed, thereby closing the xterm window. But, that doesn't work: nothing happens, so I suspect my quoting or escaping is incorrect, and I haven't been able to fix it. An alternate approach would be to get the PID of long_running_cmd, use wait to wait for it to finish, then kill the xterm window using kill $! (since $! refers to last task started in the background, which will be the xterm window). But I can't figure out a nice way to get the PID & exit value of long_running_cmd out of the shell running in the xterm window and into the shell which launched the xterm window (short of writing them to a file somewhere, which seems like it should be unnecessary?). What am I doing wrong, or is there an easier way to accomplish this?

  • Apache server completely freezes until it gets restarted

    - by nbv4
    My server does this every few days. What sucks is that it always seems to do this right after I go to bed, so when I wake up, I'm greeted with the fact that my server has been down for the past 6 or 7 hours. When I first noticed this, I added a cronjob that tries to restart the server every 15 minutes, but I guess that didn't fix it. Once I noticed the server was down, I can this command: /etc/init.d/apache2 restart * Restarting web server apache2 apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName ... waiting ...........................................................apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName httpd (pid 17597) already running ...which is odd, because a restart should restart the server, even if it's already running, correct? I eventually had to "stop" then "start" to get it working again. I then looked through the logs, and found something very weird. It seems that around the time the server crashed, the logs have entries that are wildly out of order. It looks a little like this: xx.xxx.xxx.x - - [21/Apr/2010:06:32:05 -0400] "GET / blah" xx.xxx.xxx.x - - [21/Apr/2010:06:51:25 -0400] "GET / blah" x.xx.xxx.xxx - - [21/Apr/2010:06:38:23 -0400] "GET / blah" xxx.xx.xx.xx - - [21/Apr/2010:06:31:56 -0400] "GET / blah" xxx.xx.xx.xx - - [21/Apr/2010:06:51:49 -0400] "GET / blah" xx.xx.xxx.xx - - [21/Apr/2010:06:33:20 -0400] "GET / blah" I don't think the problem is memory, because this: tells me that right before the crash, memory usage is fine. I'm running apache with the worker mpm, here are the settings for that: <IfModule mpm_worker_module> StartServers 1 MaxClients 100 MinSpareThreads 5 MaxSpareThreads 10 ThreadsPerChild 10 MaxRequestsPerChild 3000 </IfModule> This apache server is running a bunch of stuff, but most of the traffic comes from a django project I'm hosting, that uses mod_wsgi. There also is a simple machines forum that is running off of mod_fcgid. Those setting are below: <IfModule mod_fcgid.c> MaxRequestsPerProcess 500 MaxProcessCount 3 AddHandler fcgid-script .php .fcgi AddHandler cgi-script .cgi .pl FCGIWrapper "/usr/bin/php-cgi" .php </IfModule> Anyone know of anything else I can check? I've just about tweaked every single setting I can think of, yet these freezes still happen.

  • PHP hits 100% CPU and eats RAM at the same time Monday to Friday

    - by Daniel Samuels
    We run a learning platform for primary schools here in the UK and it's all been running extremely well. However at around 4PM Monday to Friday we see the same issue arise -- 1-2 PHP threads will spike to 100% CPU and gradually start eating up RAM until the server(s) fall over. 98%+ of our requests are HTTPS, these come into our Layer 7 load balancer which then decrypts the SSL data, adds the X-HTTP-Forwarded-For header and forwards the data onto an application server (we have 2 of those at the moment) on port 80. Our application servers have Varnish on port 80 which takes in the request from the load balancer and passes the request through to Nginx on port 81. Nginx then works out which 'vhost' it needs to use and passes any PHP processing through to PHP-CGI which is listening on a socket (managed through spawn-fcgi). There's an instance of Memcached running too, MySQL runs on a separate server / slave setup. Throughout the day the load will typically go no higher than 0.8 on either of the application servers, however at around 4PM our problem arises. I've managed to run strace on a few of the actual threads when they cause the problem and I always see the same thing: stat("/usr/share/zoneinfo/Europe/London", {st_mode=S_IFREG|0644,st_size=3661, ...}) = 0 stat("/usr/share/zoneinfo/Europe/London", {st_mode=S_IFREG|0644,st_size=3661, ...}) = 0 This is repeated infinitely and never stops until you SEGKILL the process or oomkiller kills it. There are no cron jobs scheduled to run at that time and I don't have any way of seeing exactly what Nginx request is associated with the PHP process which is running. We are running PHP 5.3.14 which we upgraded to from 5.3.8 last week to rule out the older version being the problem. This issue has been going on a few months now and we have no idea what is causing it. We deploy our software very frequently, so it's difficult to track down a specific release which may have started the problem - especially as we do not know the date of the first occurrence of this issue. Varnish is version 3.0.1, Nginx is 1.0.6 (which I understand is about a year old now), our servers are running CentOS release 5.7 (Final) they have Intel i3 540s at 3.07Ghz and 8GB of RAM. There's a discussion on the Debian mailing list about something very similar, you can find that here. Has anyone seen anything like this in the past, does anyone have any ideas or suggestions? Are there a way of linking an Nginx request directly to a PHP thread? Is there a better way of seeing what the PHP process is doing? (I've seen GDB mentioned, though I'll have to recompile PHP) Thanks!

  • Suspected network performance issue on VirtualBox Ubuntu guest on Win7 host

    - by Adam
    I set up Ubuntu 12.04 in VirtualBox on the Win7 machine I was allocated on my new project. I am running Java, Eclipse, Tomcat to develop a large data-intensive application and I noticed that this application runs at half the speed of my colleague's identical machine, where he runs it all under Windows. I think I have narrowed down the performance issue to the network, after comparing and equalising all the Java VM settings with my colleague. Is there a ping test I can do or some other network diagnostic test to flag up any problems? To give some background, the network performance is confusing. Running a network speed test to my colleague's machine with iperf shows speeds of 6 Mb/s from my Ubuntu guest, and 90 Mb/s from the win7 host. Large downloads, e.g. the Java SDK, come down at about 1.2 MB/s on both the guest and the host. Pings are sub-1ms on the host, but 1.5ms on the guest. I also did a broadband speed test, and got 10Mb/s download speed on both, but the host has an upload speed of 10Mb/s but the guest only uploads at 3Mb/s. I've been trying to diagnose any MTU problems with ping -M do to identify any kind of packet fragmentation problem but it's progressing very slow because I don't have much experience in this area. From what I read on other people's networking issues with VB and Linux guests on Win7 hosts, I should be able to get the speed on the guest up to the same level as the host. I installed a fresh VM with Ubuntu again to see if I'd foobar'd it somehow, but I'm getting the same readings with iperf on the virgin installation. My setup is: Adapter 1: Intel PRO/1000 MT Desktop (NAT) Adapter 2: ditto (host-only adapter) eth0 Link encap:Ethernet HWaddr 08:00:27:0b:76:bf inet addr:10.0.2.15 Bcast:10.0.2.255 Mask:255.255.255.0 inet6 addr: fe80::a00:27ff:fe0b:76bf/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:86236 errors:0 dropped:0 overruns:0 frame:0 TX packets:49369 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:69163946 (69.1 MB) TX bytes:3530535 (3.5 MB) eth2 Link encap:Ethernet HWaddr 08:00:27:a3:26:b8 inet addr:192.168.56.101 Bcast:192.168.56.255 Mask:255.255.255.0 inet6 addr: fe80::a00:27ff:fea3:26b8/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:59 errors:0 dropped:0 overruns:0 frame:0 TX packets:57 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:9148 (9.1 KB) TX bytes:7648 (7.6 KB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:701 errors:0 dropped:0 overruns:0 frame:0 TX packets:701 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:66321 (66.3 KB) TX bytes:66321 (66.3 KB)

  • How to disable or tune filesystem cache sharing for OpenVZ?

    - by gertvdijk
    For OpenVZ, an example of container-based virtualization, it seems that host and all guests are sharing the filesystem cache. This sounds paradoxical when talking about virtualization, but this is actually a feature of OpenVZ. It makes sense too. Because only one kernel is running, it's possible to benefit from sharing the same pages of filesystem cache in memory. And while it sounds beneficial, I think a set up here actually suffers in performance from it. Here's why I think why: my machines aren't actually sharing any files on disk so I can't benefit from this feature in OpenVZ. Several OpenVZ machines are running MySQL with MyISAM tables. MyISAM relies on the system's filesystem cache for caching of data files, unlike InnoDB's buffer pool. Also some virtual machines are known to do heavy and large I/O operations on the same filesystem in the host. For example, when running cat *.MYD > /dev/null on some large database in one machine, I saw the filesystem cache lowering in another, monitored by htop. This essentially flushes all the useful filesystem cache in guests (FIFO) and so it flushes the MySQL caches in the guests. Now users are complaining that MySQL is very slow. And it is. Some simple SELECT queries take several seconds on times disk I/O is heavily used by other machines. So, simply put: Is there a way to avoid filesystem cache being wiped out by other virtual machines in container-based virtualization? Some thoughts: Choosing algorithm for flushing filesystem cache in the kernel. (possible? how?) Reserving a certain amount of pages for a single VM. (seems no option for filesystem cache type of pages that reading man vzctl) Will running MySQL on another filesystem get me anywhere? If not, I think my alternatives are: Use KVM for MySQL-MyISAM running VMs. KVM actually assigns memory to the VM and does not allow swapping out caches unless using a balloon driver. Move to InnoDB and tune the buffer pools, dirty pages, etc. This is now considered to be 'nice to have' on the long-term as not everyone responsible for administration of the system understands InnoDB. more suggestions welcome. System software: Proxmox (now 1.9, could be upgraded to 2.x). One big LV assigned for the VMs.

  • how to use iptables to block the IP of device connected to openwrt router

  • SQL Express 2008 R2 on Amazon EC2 instance: tons of free memory, poor performance

    - by gravyface
    The old SQL Express 2005 was running on a low-end single Xeon CPU Dell server, RAID 5 7200 disks, 2 GB RAM (SBS 2003). I have not done any baseline measurements on the old physical server, but the Web app is used by half a dozen people (maybe 2 concurrently), so I figured "how bad can an Amazon EC2 instance be?". It's pretty horrible: a difference of 8 seconds of load time on one screen. First of all, I'm not a SQL guru, but here's what I've tried: Had a Small Instance, now running a c1.medium (High Cpu Medium) Windows 2008 32-bit R2 EBS-backed instance running IIS 7.5 and SQL Express 2008 R2. No noticeable improvement. Changed Page File from fixed 256 to Automatic. Setup a Striped Mirror from within Disk Management with two attached 1 GB EBS volumes. Moved database and transaction log, left everything else on the boot EBS volume. No noticeable change. Looked at memory, ~1000 MB of physical memory free (1.7 GB total). Changed SQL instance to use a minimum of 1024 RAM; restarted server, no change in memory usage. SQL still only using ~28MB of RAM(!). So I'm thinking: this database is tiny (28MB), why isn't the whole thing cached in RAM? Surely that would speed up performance. The transaction log is 241 MB. Seems kind of large in comparison -- has this not been committed? Is it a cause of performance degradation? I recall something about Recovery Models and log sizes somewhere in my travels, but not positive. Another thing: the old server was running SQL Express 2005. Not sure if that has any impact, but I tried changing the compatibility level from SQL 2000 to 2008, but that had no effect. Anyways, what else can I try here? Seems ridiculous to throw more virtual hardware at this thing. I know I/O is going to be rough on EBS volumes, but surely others are successfully running small .NET/SQL apps on reasonably priced instances?

  • Try out Windows Phone 7 on your PC today

    - by Matthew Guay
    Anticipation has been building for the new Windows Phone 7 Series ever since Microsoft unveiled it at the Mobile World Congress in February.  Now, thanks to free developer tools, you can get a first-hand experience of the basic Windows Phone 7 Series devices on your PC. Windows Phone 7 Series represents a huge change in the mobile field for Microsoft, bringing the acclaimed Zune HD UI to an innovative phone platform.  Windows Mobile has often been criticized for being behind other Smartphone platforms, but Microsoft seeks to regain the lead with this new upcoming release.  A platform must have developers behind it to be useful, so they have released a full set of free development tools so anyone can make apps for it today.  Or, if you simply want to play with Windows Phone 7, you can use the included emulator to try out the new Metro UI.  Here’s how to do this today on your Vista or 7 computer. Please note: These tools are a Customer Technology Preview release, so only install them if you’re comfortable using pre-release software. Getting Started First, download the Windows Phone Developer Tools CTP (link below), and run the installer.  This will install the Customer Technology Preview (CTP) versions of Visual Studio 2010 Express for Windows Phone, Windows Phone Emulator, Silverlight for Windows Phone, and XNA 4.0 Game Studio on your computer, all of which are required and cannot be installed individually. Accept the license agreement when prompted. Click “Install Now” to install the tools you need.  The only setup customization option is where to save the files, so choose Customize if you need to do so. Setup will now automatically download and install the components you need, and will additionally download either 32 or 64 bit programs depending on your operating system. About halfway thorough the installation, you’ll be prompted to reboot your system.  Once your computer is rebooted, setup will automatically resume without further input.   When setup is finished, click “Run the Product Now” to get started. Running Windows Phone 7 on your PC Now that you’ve got the Windows Phone Developer tools installed, it’s time to get the Windows Phone emulator running.  If you clicked “Run the Product Now” when the setup finished, Visual Studio 2010 Express for Windows Phone should have already started.   If not, simply enter “visual studio” in your start menu search and select “Microsoft Visual Studio 2010 Express for Windows Phone”. Now, to run the Windows Phone 7 emulator, we have to test an application.  So, even if you don’t know how to program, we can open a phone application template, and then test it to run the emulator.  First, click New Project on the left hand side of the front page. Any of the application templates would work for this, but here let’s select “Windows Phone Application”, and then click Ok. Here’s your new application template, which already contains the basic phone application framework.  This is where you’d start if you want to develop a Windows Phone app, but for now we just want to see Windows Phone 7 in action. So, to run the emulator, click Debug in the menu and then select Start Debugging. Your new application will launch inside the Windows Phone 7 Series emulator.  The default template doesn’t give us much, but it does show an example application running in Windows Phone 7.   Exploring Windows Phone 7 Click the Windows button on the emulator to go to the home screen.  Notice the Zune HD-like transition animation.  The emulator only includes Internet Explorer, your test application, and a few settings. Click the arrow on the right to see the available applications in a list. Settings lets you change the theme, regional settings, and the date and time in your emulator.  It also has an applications settings pane, but this currently isn’t populated. The Time settings shows a unique Windows Phone UI. You can return to the home screen by pressing the Windows button.  Here’s the Internet Explorer app running, with the virtual keyboard open to enter an address.  Please note that this emulator can also accept input from your keyboard, so you can enter addresses without clicking on the virtual keyboard. And here’s Google running in Internet Explorer on Windows Phone 7. Windows Phone 7 supports accelerometers, and you can simulate this in the emulator.  Click one of the rotate buttons to rotate the screen in that direction. Here’s our favorite website in Internet Explorer on Windows Phone 7 in landscape mode. All this, running right inside your Windows 7 desktop… Developer tools for Windows Phone 7 Although it may be fun to play with the Windows Phone 7 emulator, developers will be more excited to actually be able to create new and exciting apps for it.  The Windows Phone Developer Tools download includes Visual Studio Express and XNA Game Studio 4.0 which lets you create enticing games and apps for Windows Phones.  All development for Windows Phones will be in C#, Silverlight, and the XNA game framework.  Visual Studio Express for Windows Phone includes templates for these, and additionally has code samples to help you get started with development. Conclusion Many features are still not functional in this preview version, such as the search button and most of the included applications.  However, this still gives you a great way to experience firsthand the future of the Windows Phone platform.  And, for developers, this is your chance to set your mark on the Windows Phone 7 Series even before it is released to the public.  Happy playing and developing!

  • Wine is no longer able to initialize OpenGL

    - by nebukadnezzar
    Since a while, wine is no longer able to initialize OpenGL on my 64bit Linux. This is by no means a unique problem to me- Lots of people with nvidia cards running 64bit linux seem to have this problem with wine on oneiric: http://forum.winehq.org/viewtopic.php?p=66856&sid=9d6e5ad628ee6fb6e5ef04577275daed http://forum.pinguyos.com/Thread-Wine-OpenGl-Problem https://bbs.archlinux.org/viewtopic.php?id=137696 And while some launchpad bug reports say one should use this workaround: LD_PRELOAD=/usr/lib32/nvidia-current/libGL.so.1 wine <app> It unfortunately does not solve the problem at all for me; That is, if i'd run CS:S, the game will run just fine for a while, but will abort after some time, including a range of GLSL-related errors. Here the startup errors from simply running steam: + wine steam.exe fixme:process:GetLogicalProcessorInformation ((nil),0x33e488): stub [.. snip ...] fixme:dwmapi:DwmSetWindowAttribute (0x1009a, 3, 0x33d384, 4) stub fixme:dwmapi:DwmSetWindowAttribute (0x1009a, 4, 0x33d374, 4) stub err:wgl:is_extension_supported No OpenGL extensions found, check if your OpenGL setup is correct! err:wgl:is_extension_supported No OpenGL extensions found, check if your OpenGL setup is correct! err:wgl:is_extension_supported No OpenGL extensions found, check if your OpenGL setup is correct!

That being said, I'm suspecting that this is a problem of wine itself. I've already manually built the git version of wine, to no avail. So what's going on? Is something broken? How do I check (correctly) whether something is broken? How do I solve this?

  • You are probably NOT a SharePoint Development Expert if&hellip;

    - by Mark Rackley
    So, all you aspiring SharePoint experts out there (especially those of you who put “expert” in your resumes).  It’s time for a cold cool splash of reality. More than likely you are NOT an expert (I know I’m not). Yes, you may have some expertise in certain aspects in SharePoint (it’s questionable if I have THAT some days), but make sure you’ve got the basics down before you start throwing that word “expert” around. I know that it becomes frustrating to those looking to hire SharePoint people and having to sift through all the resumes of those who think very highly of themselves and their skills only to find those gaping holes in common best practices. I’m much more willing to hire a decent dev who KNOWS they are not an expert than to hire a decent+ dev who THINKS they are an expert.  So… I’ve compiled a small reality check for you SharePoint Devs. and a “red flag” check for those of you wishing to hire a SharePoint developer. If any of these apply to you, you are probably not a SharePoint Development Expert. You are not a SharePoint Development Expert if you manually copy your DLLs Seriously, I don’t care if you write the best code in the world. If you are manually copying files to each web front end you are NOT a SharePoint Development expert. Yes, I realize the admins are generally the ones who do the actual deployments, but if you don’t know how to create solution packages for your admins, you are going to end up doing more damage than good some day. There are TONS of tools out there to help generate deployable solutions for you. You have ZERO excuse. You are not a SharePoint Development expert if you can’t tell me the main artifacts of a solution package Directly related to the first one. If you don’t know what the Manifest, DDF, WSP, and Feature files are and how they are used in a solution package, you are NOT a SharePoint development expert. I’m not asking you to be able to write them all from scratch (heck, I can’t even do that), but you MUST know what they are and how to tweak them if necessary. You are not a SharePoint Development expert if you don’t know what a Content Type or a Site Column is You would be absolutely amazed at how many “Expert” SharePoint Developers have NEVER EVER created a Content Type or Site Column or even know what they are. I mean, why would you ever want to create those when you can just do everything as a custom list or custom field? right???? (that’s sarcasm). You also need to know how to package a Content Type and a Site Column into a deployable package by the way. You are not a SharePoint Development expert if you have not created at least one Web Part, Workflow, Timer Job, and Event Handler. If you haven’t written at least one of each, you don’t fully understand what they do or their limitations. Again, I expect NO ONE to be able to write these things blind. I think the last time I wrote an application from scratch without copying and pasting from another project I had done before was back in 1994? Seriously, coding is like a Sour Dough starter, you get it from someone else and keep adding to it. You are not a SharePoint Development expert if you don’t know how to properly dispose of objects Another biggie with zero excuse for getting it wrong. It is so well known that you must dispose of your SPWeb and SPSite objects that if you aren’t doing it then you are not an expert. Heck, if you utilize “using” when handling SPWeb and SPSite objects and don’t realize that it disposes of those objects for you, then you are not a SharePoint Development expert. You are not a SharePoint Development expert if you do not know how to properly elevate privileges Just one of those development basics that any decent SharePoint Developer has got to have down and understand how and why it’s used You are not a SharePoint Development expert if you don’t know all of the development options available to SharePoint and when they should be used Okay… so all you hard core .NET SharePoint dev geeks take a moment to listen. You may be the most top not SharePoint .NET developer in the world, but if you are opening Visual Studio to solve every problem in SharePoint, then you are NOT a SharePoint development expert. The SharePoint developer’s tool kit is growing every day with tools like Visual Studio, Data View Web Parts, XSL, jQuery, SPServices, etc. etc… If you don’t have the ability to at least recognize that “hey, you can basically do the same thing here but just dropping in Easy Tabs instead of writing some weird web part” then you are NOT a SharePoint Development expert AND you are doing a huge disservice to your clients and customers. You are probably NOT a SharePoint Development expert if you call yourself an Expert So, truth telling time. I’m not an expert. There, I said it. I feel so much better. Now, I realize the word “expert” has been used with my name before, but I am quick to point out that I KNOW the experts and know that they will help me if I need it, but I’m not an expert in all things SharePoint. The minute you take on that moniker you are setting yourself up for a fall. It’s too big, there’s too much to know, and there’s WAY too much you can do wrong. You are not a SharePoint Development expert if you are not involved in the community I expect to get the most flack for this one, but it’s always a huge red flag for me when someone says they are an expert and has ZERO knowledge of the SharePoint community. The SharePoint community is ABSOLUTELY CRITICAL to be an effective SharePoint developer, admin, architect, power user or whatever the heck you are!! The community keeps you sane, tells you when you are NOT using a best practice, recommends the best practice, and even knows when Microsoft is giving you the wrong information (*gasp* it does happen). If you can’t tell me who you are following on twitter, who's blog you read, what conferences you attend, or name the experts who you monitor to make sure you are not doing something stupid, then you are probably doing something stupid. Again, not asking you to be a speaker, blogger, or the least bit extroverted but you should be at LEAST stalking the experts. So… what’s the point? So… yeah… what’s my point in all this. Well, first of all let me point out that this is by far not a finished list and I could come up with a LOT more specific “deep dive” questions, but these should be high enough level that even non experts can recognize and ask them. If you have some common ones you run into let me know and add them in the comments below. Also, keep in mind I’m not saying you as a developer HAVE to know EVERYTHING, but you DO need to know what you don’t know and proudly and honestly state “I don’t know, but I’ll learn and find out”.  Those of us hiring SharePoint developers and know and have a passion for SharePoint are not looking for that elusive “expert” who knows everything. We are looking for someone who “gets it”, has a similar passion, great attitude, an understanding that they DON’T know everything, and a desire to do it right.  I would bet money that most SharePoint development disasters happen because of “experts” who think they know everything rather than the developer who is cautious and knows he doesn’t. Lastly, I know there’s a raging debate over what a “SharePoint Developer” is (I should know, as I keep bringing it up). So, obviously this blog post is more closely tied to the .NET side of SharePoint development and less towards the client side, middle tier, or whatever you want to call it. So, let’s please not get that argument going here as well…  Thanks

  • JPA Entity (in multiple persistence-unit) in OSGi (Spring DM) Environnement is confusing me.

    - by Vincent Demeester
    Hi, I'm a bit confused about a strange behavior of my JPA's related objects. I have three bundle : The User bundle does contain some user-related objects, but mainly the User object. The Energy bundle does contain some energy-related objects, and particularly a ConsumptionTerminal which contains a List of User. The Index bundle does contain an Index object that has no dependency at all. My OSGi environment is the following : A DataSource bundle that provide 2 services : dataSource and jpaVendorAdapter. The three bundles. They consume dataSource and jpaVendorAdapter. Their module-context.xml file look like : And they all have a persistence.xml file : User <?xml version="1.0" encoding="UTF-8"?> <persistence> <persistence-unit name="securityPU" transaction-type="JTA"> <jta-data-source>java:/securityDataSourceService</jta-data-source> <class>net.nextep.amundsen.security.domain.User</class> <!-- [...] --> <exclude-unlisted-classes>true</exclude-unlisted-classes> <properties> <property name="eclipselink.logging.level" value="INFO" /> <property name="eclipselink.ddl-generation" value="create-tables" /> <property name="eclipselink.ddl-generation.output-mode" value="database" /> <property name="eclipselink.orm.throw.exceptions" value="true" /> </properties> </persistence-unit> </persistence> Energy <?xml version="1.0" encoding="UTF-8"?> <persistence> <persistence-unit name="energyPU" transaction-type="JTA"> <jta-data-source>java:/securityDataSourceService</jta-data-source> <class>net.nextep.amundsen.security.domain.User</class> <class>net.nextep.amundsen.energy.domain.User</class> <!-- [...] --> <exclude-unlisted-classes>true</exclude-unlisted-classes> <properties> <property name="eclipselink.logging.level" value="INFO" /> <property name="eclipselink.ddl-generation" value="create-tables" /> <property name="eclipselink.ddl-generation.output-mode" value="database" /> <property name="eclipselink.orm.throw.exceptions" value="true" /> </properties> </persistence-unit> </persistence> Index : This one has the most simple persistence.xml with just the Index class (no shared Class). I'm using named @PersistenceUnit annotation like @PersitenceUnit(name = 'securityPU') (for the User bundle). And finally, I'm using EclipseLink as Jpa provider and Spring DM (+ Spring DM Server in the development process) The problem is the following : When the User bundle is deployed, I'm able to persist User objects. When the User bundle and Energy bundles are both deployed, I'm not able to persist User objects (neither the Energy object). But I don't have any exception at all ! There is no problem at all with the Index bundle. The bug is dataSource independent (I tried with PostgreSQL and MySQL so far). My first conclusion was that the <class>net.nextep.amundsen.security.domain.User</class> in both persistence unit was causing the trouble. I tried without it (and hiding the User dependent object in the Energy bundle) but it failed too. I'm a bit confused about that bug. I'm also not quite sure about the transaction management in this context. I wasn't the one who designed this architecture (but I tell my intern OK without testing it.. shame on me) but if I could understand this bug and maybe fix it without rewrite the bundle (and break my intern work), I would appreciate. Am I doing something wrong ? (it's obvious, but what..) Did I miss something while reading documentation ? By the way, I'm also looking for some best practices or advices when it comes to JPA, EclipseLink (or whatever JPA Provider) and Spring DM (and OSGi in general). I found interesting slides from Mike Keith about this topic (by browsing Stackoverflow).
