  • Server getting overloaded

    - by taras
    Hi, I have 2 setups tomcat5.5.20 on Redhat and mysql 4.1.22 on another Redhat server. Recently my webserver started getting overloaded up to 80-90%. After checking i found repeating errors(each seconds) in catalina.out. Can it cause the server overload or where else can be the root of the problem ? catalina.out: DBCP object created 2010-12-22 13:33:12 by the following code was never closed: java.lang.Exception at org.apache.tomcat.dbcp.dbcp.AbandonedTrace.init(AbandonedTrace.java:96) i have to restart tomcat once a day when server load reaches 80-90%. Also catalina.out file is growing too fast which every few hours need to clear the logs. My datasource config: <bean id="myDataSource" class="org.apache.tomcat.dbcp.dbcp.BasicDataSource" destroy-method="close"> <property name="driverClassName"> <value>com.mysql.jdbc.Driver</value> </property> jdbc:mysql://XXX/XXX?autoReconnect=true 20 20 <property name="maxIdle"> <value>50</value> </property> <property name="maxActive"> <value>50</value> </property> <property name="removeAbandoned"> <value>false</value> </property> <property name="removeAbandonedTimeout"> <value>2400</value> </property> <property name="username"> <value>XXX</value> </property> <property name="password"> <value>XXX</value> </property> </bean> Thanks for any direction.

  • Is there a limit setting a php_admin_value in php-fpm?

    - by PeeHaa
    I am trying to set a large value in the configuration of a pool in php-fpm, but at some point it just doesn't start anymore. php_admin_value[disable_functions] = dl,exec,passthru,shell_exec,system,proc_open,popen,curl_exec,curl_multi_exec,parse_ini_file,show_source,pcntl_exec,include,include_once,require,require_once,posix_mkfifo,posix_getlogin,posix_ttyname,getenv,get_current_use,proc_get_status,get_cfg_va,disk_free_space,disk_total_space,diskfreespace,getcwd,getlastmo,getmygid,getmyinode,getmypid,getmyuid,ini_set,mail,proc_nice,proc_terminate,proc_close,pfsockopen,fsockopen,apache_child_terminate,posix_kill,posix_mkfifo,posix_setpgid,posix_setsid,posix_setuid,fopen,tmpfile,bzopen,gzopen,chgrp,chmod,chown,copy,file_put_contents,lchgrp,lchown,link,mkdi,move_uploaded_file,rename,rmdi,symlink,tempnam,touch,unlink,iptcembed,ftp_get,ftp_nb_get,file_exists,file_get_contents,file,fileatime,filectime,filegroup,fileinode,filemtime,fileowne,fileperms,filesize,filetype,glob,is_di,is_executable,is_file,is_link,is_readable,is_uploaded_file,is_writable,is_writeable,linkinfo,lstat,parse_ini_file,pathinfo,readfile,readlink,realpath,stat,gzfile,create_function When trying to restart php-fpm it fails with the following message: Stopping php-fpm: [ OK ] Starting php-fpm: [20-Oct-2013 22:31:52] ERROR: [/etc/php-fpm.d/codepad.conf:235] value is NULL for a ZEND_INI_PARSER_ENTRY [20-Oct-2013 22:31:52] ERROR: Unable to include /etc/php-fpm.d/codepad.conf from /etc/php-fpm.conf at line 235 [20-Oct-2013 22:31:52] ERROR: failed to load configuration file '/etc/php-fpm.conf' [20-Oct-2013 22:31:52] ERROR: FPM initialization failed [FAILED] When I remove the last disabled function (create_function) it start again. I also tried with other functions, but this gives the same error so it's not related to the create_function function. The string currently is just over 1KB in size so it looks like I have hit a limit here? Is my assumption correct? Is there a way to overcome this limit? I also tried to add another php_admin_value[disable_functions] underneath it (hoping it would be appended), but that didn't work (it just used the first one).

  • Is Cherokee (probably) the best static content server for beginner sysadmins?

    - by Bad Learner
    I have read the pros and cons of most of the popular web servers and have come to a conclusion that Apache would (probably) be the best web server for serving dynamic content - - no wonder YouTube, Flickr and Facbook, among many others, use it. I do not know if that C10K problem applies to Apache even when serving dynamic content only, but I think any web server used to serve dynamic content needs some good tweaking for optimized performance, and the fact that nothing beats Apache when it comes to documentation, resources and support on the web, I think should will go with Apache for dynamic content. That apart, the confusion begins when it comes to choosing web servers for static content (including streaming videos). I see that Nginx, Cherokee and Lighttpd are among the best (I am not considering non-open source or non-linux stuff here). So, which too choose? I know one cannot go wrong with any of the three (Nginx, Cherokee, Lighttpd). Lighttpd's development has evidently gotten slower than it was a good time ago. The documentation is pretty good for all the three, and hopefully, so are the resources (knowledge of these among the users of Stackoverflow/Serverfault sites, the web etc). Precisely, and noting point [2] and [3], if I am not wrong, I should either go with Nginx or Cherokee. I would love to see someone clarify these... is Cherokee just as fast (mb/s), performant (connections/s), and reliable (think downtime/restarting server) as Nginx for serving static content and load balancing, for small, medium to large (and really large) websites and applications? (Think, the size of YouTube, Apache or Facebook.) if the answer for the Q above is a big "hell, yes!" then, I should probably prefer Cherokee, right? Because, since I am a beginner, it would a lot easier to setup Cherokee as it has a graphical admin user interface + really good documentation. Yes? I could be wrong, I could be right. I put down what I know so that you can offer most relevant advise. Pardon if anything I've said is offensive.

  • IIS replication - Is it possible

    - by Ian
    Hi All, I have a requirement for a client that I have a centralised system that all his satellite branches can work on. Currently this is a ASP.net web forms app running under IIS 7 on win 2008 RC 2 using an SQL backend. The client has now requested that each branch have a local server, so that in the event that the internet connection is down, the branches productivity does not suffer. His other request is that everything can be updated via the central hub and using some mechanism the updates filter down to the individual sites. What are my options here? I see the following as possible options: Multiple redundant internet connections controlled by load balancers SQL replication for the DB (What is better, snapshot, merge or transactional) Roll my own IIS sync service the periodically checks if there is a new version of the web app and downloads it (I hope there are better option than this) Something way better I don’t yet know about (I hope this is the one I need) One of my clients concerns are that the branches are often in very remote areas where everything from technicians to internet is hard to find and very scarce. Any ideas, suggestions, tips etc are welcome. Thanks all

  • Monitoring AWS Systems Behind ElasticBeanStalk

    - by A. Avadis
    So I'm getting a company set up in the Amazon Cloud -- creating IAAS protocol/solutions/standardized implementation, etc while also being the SysAdmin for individual systems, app environments, and day-to-day uptime. One of the biggest issues I'm having is tracking various system/application logs, as well as logging/monitoring/archiving system metrics like memory usage, cpu usage, etc etc In a centralized fashion. E.g. -- Nagios + Urchin. The BIGGEST impediment to my endeavors is the following: The company application is deployed in the form of a Java *.WAR file, uploaded to an Elastic BeanStalk application environment, load balancing and auto-scaling between 3(min) and 10(max) servers, and the EC2's that run the application are fired up and disposed of ad-hoc. That is to say, I can't monitor the individual EC2's for very long because so many are being terminated then auto-provisioned/auto-scaled on the fly -- so I'd constantly be having to "monitor what I'm monitoring", and continuously remove/add EC2 machine addresses to my monitoring lists. IS there some sort of way to use monitoring tools like Zabbix or Nagios to monitor the ElasticBeanStalk, and have it automatically add on new EC2's, and remove terminated/failed EC2's from its monitoring list automatically? Furthermore, is there anything I can do with GrayLog to achieve similar results with the aggregation/centralization of my application logs from multiple EC2 instances into ONE consolidated set of logs/events? If not GrayLog, is there ANYTHING LIKE GrayLog that can automatically detect what EC2 members are being added/removed from the environment, and collect the logs from them automatically? Any and all advice or direction is appreciated. Thanks much, and cheers!!

  • How do i install apache on my ubuntu 12.04 where it has virtualhost

  • How to test a HTTPS URL with a given IP address

    - by GreatFire
    Let's say a website is load-balanced between several servers. I want to run a command to test whether it's working, such as curl DOMAIN.TLD. So, to isolate each IP address, I specify the IP manually. But many websites may be hosted on the server, so I still provide a host header, like this: curl IP_ADDRESS -H 'Host: DOMAIN.TLD'. In my understanding, these two commands create the exact same HTTP request. The only difference is that in the latter one I take out the DNS lookup part from cURL and do this manually (please correct me if I'm wrong). All well so far. But now I want to do the same for an HTTPS url. Again, I could test it like this curl https://DOMAIN.TLD. But I want to specify the IP manually, so I run curl https://IP_ADDRESS -H 'Host: DOMAIN.TLD'. Now I get a cURL error: curl: (51) SSL: certificate subject name 'DOMAIN.TLD' does not match target host name 'IP_ADDRESS'. I can of course get around this by telling cURL not to care about the certificate (the "-k" option) but it's not ideal. Is there a way to isolate the IP address being connected to from the host being certified by SSL?

  • Debian x86_64 + Nginx + PHP5-FPM optimization

    - by Olal'a
    I used to have a VPS (512MB) from Linode and I was running nginx + php5-fpm (which comes with php5.3.3) on Debian Lenny (i686). The total memory usage was about 90-100MB. Now I have another VPS (different hosting company) and I also run nginx + php5-fpm on Debian Lenny (x86_64). The system is 64-bit, so the memory usage is higher now, about 210-230MB, which I think is too much. Here is my php5-fpm.conf: pm = dynamic pm.max_children = 5 pm.start_servers = 2 pm.min_spare_servers = 2 pm.max_spare_servers = 5 pm.max_requests = 300 That's what top command tells me: top - 15:36:58 up 3 days, 16:05, 1 user, load average: 0.00, 0.00, 0.00 Tasks: 209 total, 1 running, 208 sleeping, 0 stopped, 0 zombie Cpu(s): 0.0%us, 0.0%sy, 0.0%ni, 99.9%id, 0.1%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 532288k total, 469628k used, 62660k free, 28760k buffers Swap: 1048568k total, 408k used, 1048160k free, 210060k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 22806 www-data 20 0 178m 67m 31m S 1 13.1 0:05.02 php5-fpm 8980 mysql 20 0 241m 55m 7384 S 0 10.6 2:42.42 mysqld 22807 www-data 20 0 162m 43m 22m S 0 8.3 0:04.84 php5-fpm 22808 www-data 20 0 160m 41m 23m S 0 8.0 0:04.68 php5-fpm 25102 www-data 20 0 151m 30m 21m S 0 5.9 0:00.80 php5-fpm 10849 root 20 0 44100 8352 1808 S 0 1.6 0:03.16 munin-node 22805 root 20 0 145m 4712 1472 S 0 0.9 0:00.16 php5-fpm 21859 root 20 0 66168 3248 2540 S 1 0.6 0:00.02 sshd 21863 root 20 0 66028 3188 2548 S 0 0.6 0:00.06 sshd 3956 www-data 20 0 31756 3052 928 S 0 0.6 0:06.42 nginx 3954 www-data 20 0 31712 3036 928 S 0 0.6 0:06.74 nginx 3951 www-data 20 0 31712 3008 928 S 0 0.6 0:06.42 nginx 3957 www-data 20 0 31688 2992 928 S 0 0.6 0:06.56 nginx 3950 www-data 20 0 31676 2980 928 S 0 0.6 0:06.72 nginx 3955 www-data 20 0 31552 2896 928 S 0 0.5 0:06.56 nginx 3953 www-data 20 0 31552 2888 928 S 0 0.5 0:06.42 nginx 3952 www-data 20 0 31544 2880 928 S 0 0.5 0:06.60 nginx So, the question is there any way to use less memory?

  • PowerShell 3.0 x64 bit broken after installing KB2506143

    - by Dave Parker
    I have searched using all kinds of variations on relevant terms and I cannot find a single other instance of someone else having this excact same problem, so I am hoping someone here may have a clue. Problem I installed Windows Management Framework 3.0 (KB2506143) by downloading and running Windows6.1-KB2506143-x64.msu from Microsoft.com. Once completed I rebooted my machine as requested. After rebooting and logging in, I try to run the 64-bit PowerShell command shell and it comes up for a second then goes away. The 32-bit shell seems to work fine, it is just the 64-bit one that fails. Looking in the Fusion logs, I found: *** Assembly Binder Log Entry (10/4/2012 @ 1:51:48 PM) *** The operation failed. Bind result: hr = 0x80070002. The system cannot find the file specified. Assembly manager loaded from: C:\Windows\Microsoft.NET\Framework64\v2.0.50727\mscorwks.dll Running under executable C:\WINDOWS\system32\WindowsPowerShell\v1.0\powershell.exe --- A detailed error log follows. === Pre-bind state information === LOG: User = ********\***** LOG: DisplayName = Microsoft.PowerShell.ConsoleHost, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL <remainder omitted> GacUtil reveals that there is a Microsoft.PowerShell.ConsoleHost, Version=1.0.0.0, but not 3.0.0.0. I tried uninstalling KB2506143 (which removed MSVCRT90.dll and caused Windows Live Messenger to fail on load after rebooting again, so I ran a repair in stall on Windows Live Essentials and that fixed the Messenger problem) and then re-installing it, but nothing changed. If it helps, here are what I think may be the relevant parts of my hardware/software environment. Environment Dell Latitude E6510, 8GB RAM Windows 7 Professional 64-bit with SP1 Visual Studio 2010 Professional installed (includes .NET 4.0) Visual Studio 2012 Professional installed Microsoft Forefront Client Security Any clues out there? Thanks, Dave

  • IIS 6 ASP.NET default handler-mappings and virtual directories

    - by Mark Lauter
    I'm having a problem with setting a default mapping in IIS 6. I want to secure *.HTML files with ASP.NET forms authentication. The problem seems to have something to do with using virtual directories to hold the html files. Here's how it's setup: sample directory tree c:/inetpub/ (nothing in here) d:/web_files/my_web_apps d:/web_files/my_web_apps/app1/ d:/web_files/my_web_apps/app2/ d:/web_files/my_web_apps/html_files/ app1 and app2 both access the same html_files directory, so html_files is set as a virtual directory in the web apps in IIS... sample web directory tree //app1/html_files/ (points to physical directory: d:/web_files/my_web_apps/html_files/) //app2/html_files/ (points to physical directory: d:/web_files/my_web_apps/html_files/) If I put a file called test.html in the root of //app1/ and then add the default mapping to the asp.net dll and setup my security on the root folder with deny="?", then accessing test.html works exactly as expected. If I'm not authenticated, it takes me to the login.aspx page, and if I am authenticated then it displays test.html. If I put the test.html file in the html_files directory I get a totally different behavior. Now the login.aspx page loads and I stuck some code in to check if I was still authenticated: <p>autheticated: <%=User.Identity.IsAuthenticated%></p> I figured it would say false because why else would it bother to load the login page? Nope, it says true - so it knows i'm authenticated, but it won't give me access to the test.html file. I've spent several hours on this and haven't been able to solve it. I'm going to spend some more time on google to see if I've missed something. Fingers crossed.

  • PHP 5.3.2 Upgrade on Windows

    - by mcondiff
    I have a development box running Windows XP, Apache 2.2.15 Mysql and PHP 5.2.6 About a month ago I updated the Apache to the latest version and it went swimmingly. I am not having the same success with upgrading PHP to the latest version. I backed up my PHP directory and then deleted it. Used the Windows Installer for PHP 5.3.2, installed as an Apache 2.2.X module. I can get "Hello World" and phpinfo() to come up but cannot get mysql to connect. I have the extension un-commented in the php.ini and shouldn't really have to touch the Apache httpd.conf file since I didn't change the directory of PHP. Not sure what I'm doing wrong here. I have to get this right and then upgrade the Live Server too so I want to get this down pat. I've tried to use installation guides on the web with no luck. Any info pertaining to this problem would be great. I'm also afraid that the other PHP modules may not load but cannot really tell anything past mysql not working.

  • What should be monitored to troubleshoot file sharing problems?

    - by RyanW
    I'm running into some problems with a file share used by an ASP.NET web application. With this configuration, there are 2 web servers (win2k8 web) that connect to a file server (win2k8 enterprise), reading and writing files using a file share. Recently, one of the web servers has begun encountering an error accessing the file share: IOException: The specified network name is no longer available. There does not appear to be much info on the web for explaining what's causing this and how to best fix it, so I'm looking at what I can monitor in order to get clues. I'm not sure if it's hardware, just a load issue, file size, frequency, etc. With Windows perfmon, what can I monitor on the File Server side? There's the "Files Open" object, any other good ones? What can I monitor on the web server side? EDIT: I'll add that the UNC path uses the IP address of the file server, not a name to resolve. Also the share is a single, flat directory with over 100K files.

  • Issues regarding internet connectivity

    - by andySF
    Hello. My problem started when Yahoo Messenger stopped connecting. I've tried to see if Internet Explorer was working but will not load any page. The diagnostics of Internet Explorer says that is something wrong with my dns(using just ip of google or yahoo or my local webserver was not working). I use Windows 7 and at the moment i've had Internet Explorer 8 and after a lot of failing updates to ie9 I've successfully install the Romanian version of IE9(now i have ie8 after a system restore). Then I installed the service pack 1. I've done a lot of things and I will try to enumerate them, but my problem persists. Settings from Yahoo Messenger and Internet Explorer are OK. I've try to reset winsock and ip from netsh. I've scanned my pc with spybot, mallwarebytes, Trojan Remover(simplysup), Loaris Trojan Remover, Avast, Nod32, Kaspersky, Bitdefender,alot of registry cleaner including CCleaner and maybe others that I cannot remember now. I reset the registry permissions using subinacl. At a moment my files permissions was set jut to "trusted installer" and I've put the permission back to files and folders using the model of other windows 7 machine. I have try so many things that now i'm stuck in a loop using different security tools to check for problems. Oh, and my virtual machines are working just fine.(I'm using VirtualBox) Please Help. PS, Reinstalling Windows is not an option. Thank you!

  • VLAN for WiFi traffic separation (new to VLANing)

    - by Philip
    I run a school network with switches in different departments. All is routed through to a central switch to access the servers. I would like to install WiFi access points in the different departments and have this routed through the firewall (an Untangle box that can captive-portal the traffic, to provide authentication) before it gets onto the LAN or to the Internet. I know that the ports that the APs connect to on the relevant switches need to be set to a different VLAN. My question is how do I configure these ports. Which are tagged? Which are untagged? I obviously don't want to interrupt normal network traffic. Am I correct in saying: The majority of the ports should be UNTAGGED VLAN 1? Those that have WiFi APs attached should be UNTAGGED VLAN 2 (only) The uplinks to the central switch should be TAGGED VLAN 1 and TAGGED VLAN 2 The central switch's incoming ports from the outlying switches should also be TAGGED VLAN 1 and TAGGED VLAN 2 There will be two links to the firewall (each on its own NIC), one UNTAGGED VLAN 1 (for normal internet access traffic) and one UNTAGGED VLAN 2 (for captive portal authentication). This does mean that all wireless traffic will be routed over a single NIC which will also up the workload for the firewall. At this stage, I'm not concerned about that load.

  • What to do when a device has no driver for Windows 7 but it has Vista, XP drivers

    - by Mehper C. Palavuzlar
    This has always been a bothersome matter for me. Some devices (printers, scanners, etc.) have drivers for older versions of Windows (Vista, XP, 2000, NT) but no driver for Windows 7. What are my chances to install such devices on Windows 7? Example case: I have a Sharp printer & scanner (Sharp AR-122E N) which I have used for my old Windows XP based PC. Now I want to install it on a Windows 7 x64 based PC. Windows 7 cannot load its driver. I used the original driver CD but when I run the setup.exe (which is included in AR122EN111.exe, 6713KB), it says Cannot install driver on this operating system. Supported operating systems are: Windows 2000, XP, Vista. I tried to install the driver using compatibility settings. I tried Windows Vista and Windows XP SP3, but to no avail. The setup gave the same error. I also googled for Windows 7 driver for "Sharp AR-122E N" but it only listed the original driver that I tried. The official site of Sharp does not even list the driver for this product. In the past, the compatibility setting workaround did work for some devices, but this time it failed. What else can I do to overcome this problem?

  • How should I perform database maintenance on a 24x7 system

    - by solublefish
    I'm a software developer who inherited a part-time DBA role. I'm responsible for an application backed by a small, high-volume 24x7 database on SQL Server 2008. While there's other stuff in the DB, the critical piece is a 50GB, 7.5M row table that serves 100K requests/sec during peak load, and about half that at "night". This is 99%+ read traffic, but the writes are constant, and required. I need to be able to perform periodic maintenance without a maintenance window. Say an index rebuild, a job to purge old data, Windows Update, or hardware upgrade. Most of the advice I've seen is along the lines of "MAKE a maintenance window." While I appreciate the sentiment, I hope there's another way. If it will solve this problem, I do have the ability to purchase new hardware or modify the database, the clients (a set of web services servers), and much of the application code (ADO.NET + ASP.NET). I've been thinking along the lines of using the warm spare (or a 3rd server) to do the maintenance, and then "swap" it into production. 1 Synchronize the spare by restoring backups, including a current transaction log. 2 Perform the maintenance tasks. 3 Reconfigure clients to connect to the spare server. Existing connections are finished within a minute or so. 4 The spare server is now the production server. The problem remaining is that the new production server is now out of date by however long it took to perform maintenance. Is there some way that the original production server can be made to queue up changes and merge them to the spare between steps 2 and 3? Any other ideas?

  • Can't Install Win2k8 On KVM - Classic 0x80070013 error

    - by javano
    I am trying to install Win2k8 Std as a KVM guest on Debian Squeeze. As you can see from these screen shots; No drives are detected (I have blanked out a 20GB image for testing) - screenshot1 I am using this driver CD: - screenshot2 I have signed the Win7 driver (I assume this was the most appropriate one?) - screenshot3 I can now see an unpartitioned drive - screenshot4 But I can't create a new partition on here, getting the error code 0x80070013 - screenshot5 I have had this error code before but only on a physical server. If I remember correctly it was complaining because the disks were partitioned as GPT (because it was a server that was being re-purposed) so repartitioning with an MS-DOS table fixed that. This is a blank disk image though. What is wrong here, and how can I correct this? Thank you. UPDATE I have booted the VM with a Gparted-Live disk and formatted this volume with an MS-DOS partitioning scheme, and a single 20GB NTFS file system. Now when I boot the Win2k8 CD, load my drivers, I get a different error. As you can see at the bottom of screenshot6 "Windows cannot be installed on this hard drive space. Windows must be installed to a partition formatted as NTFS". Clicking format produces the error (0x80004005) on the screen, so I think this is still a driver issue because Windows can see the drive but not interact with it properly. Is that insane thinking?

  • How to bypass vpn talking to VMWare Guest?

    - by marc esher
    Greetings. Network/VPN n00b question here. I'm running VMWare Workstation with a Guest Windows 2003 Server. It has SQL Server 2000 installed. The sole purpose for this Guest is to house SQL Server... it needn't have internet access or access to any other resources on the network other than the host. When launch Check Point VPN software, the host routes through the company network before it connects to the guest ... i.e. it's no longer a direct connection. I assume this is just how things are supposed to work. However, what's happening is that the connection between my host and the SQL Server instance on the guest intermittently drops. It's not consistent, and some databases on the server will be responsive while others aren't. It appears that the databases with the most traffic on the guest (the ones I'm hitting with load tests) are the ones that become intermittently unresponsive. This problem only manifests when VPN is on; when it's off, I can pound away on this database with no troubles. Thanks for any advice!

  • Photo managing software that supports network drives?

    - by musicfreak
    My dad is a photographer in his free time, and he's been using Lightroom to manage his photos. However, recently, we put all of our photos on a NAS drive to allow us to access them from any computer at any time. The problem with this is that Lightroom cannot load catalogs from network drives. We need support for network drives because we'd like to be able to browse the photos from any computer, and for any computer to be able to add photos to the collection. Right now we're just syncing the Lightroom catalog file between us, but the extra step is a pain, and doing it manually makes it error-prone. Is there any software (free or commercial) that has proper support for network drives? The only real feature I need is to be able to sort photos by date and by some sort of tags. I don't need any editing features like those found in Lightroom; my dad is comfortable using Photoshop to edit photos. Also, if there is another solution to this that I haven't thought of, feel free to share.

  • Squid reverse proxy array - siblings not communicating with each other

    - by V. Romanov
    I want to set up 2 squid servers to act as reverse proxy and cache for a webserver on our intranet. The load balancing will be done with DNS round robin or just different mappings for different clients. The thing is, I want both servers to try and contact each other to see if they have the object required in cache before contacting the webserver for it (the network that servers the webserver is the bottleneck and I'm trying to eliminate it) Both squids are configured the same, here are the relevant config lines : acl dvr1_cache_it_best_tv_com dstdomain dvr1.cache.it.best-tv.com acl squid1_it_best_tv_com dstdomain squid1.it.best-tv.com acl squid2_it_best_tv_com dstdomain squid2.it.best-tv.com http_access allow dvr1_cache_it_best_tv_com http_access allow squid1_it_best_tv_com http_access allow squid2_it_best_tv_com http_access allow all http_port 8081 accel defaultsite=dvr1.cache.it.best-tv.com cache_peer dvr1.origin.it.best-tv.com parent 80 0 no-query originserver name=Proxy_dvr1_origin_it_best_tv_com cache_peer squid1.it.best-tv.com sibling 8081 3130 weight=10 name=Proxy_Squid1_it_best_tv_com cache_peer squid2.it.best-tv.com sibling 8081 3130 weight=10 name=Proxy_Squid2_it_best_tv_com cache_peer_access Proxy_dvr1_origin_it_best_tv_com allow dvr1_cache_it_best_tv_com cache_peer_access Proxy_squid1_it_best_tv_com allow squid1_it_best_tv_com cache_peer_access Proxy_squid1_it_best_tv_com allow squid2_it_best_tv_com cache_peer_access Proxy_squid1_it_best_tv_com allow dvr1_cache_it_best_tv_com cache_peer_access Proxy_squid2_it_best_tv_com allow squid1_it_best_tv_com cache_peer_access Proxy_squid2_it_best_tv_com allow squid2_it_best_tv_com cache_peer_access Proxy_squid2_it_best_tv_com allow dvr1_cache_it_best_tv_com just to make it clear - dvr1.cache is the alias for the proxy servers. dvr1.origin is the web server. Both servers work, both serve content and cache it and work fine. However, when I clear the cache on one server and then access it, it gets the content from the parent (DVR1_ORIGIN) instead of going to the sibling squid. What did I configure wrong? Or perhaps I don't understand the architecture correctly? I read the squid manuals but as far as I see i did it all by the book and yet it doesn't work right. Any help will be appreciated!

  • Standards for documenting/designing infrastructure

    - by Paul
    We have a moderately complex solution for which we need to construct a production environment. There are around a dozen components (and here I'm using a definition of "component" which means "can fail independently of other components" - e.g. an Apache server, a Weblogic web app, an ftp server, an ejabberd server, etc). There are a number of weblogic web apps - and one thing we need to decide is how many weblogic containers to run these web apps in. The system needs to be highly available, and communications in and out of the system are typically secured by SSL Our datacentre team will handle things like VLAN design, racking, server specification and build. So the kinds of decisions we still need to make are: How to map components to physical servers (and weblogic containers) Identify all communication paths, ensure all are either resilient or there's an "upstream" comms path that is resilient, and failover of that depends on all single-points of failure "downstream". Decide where to terminate SSL (on load balancers, or on Apache servers, for instance). My question isn't really about how to make the decisions, but whether there are any standards for documenting (especially in diagrams) the design questions and the design decisions. It seems odd, for instance, that Visio doesn't have a template for something like this - it has templates for more physical layout, and for more logical /software architecture diagrams. So right now I'm using a basic Visio diagram to represent each component, the commms between them with plans to augment this with hostnames, ports, whether each comms link is resilient etc, etc. This all feels like something that must been done many times before. Are there standards for documenting this?

  • mysql thread count

    - by Ryan M.
    We have a web application that uses apache and mysql. Generally (according to Munin) our MySQL thread count sits between 2 and 4 at all times. The other day, our server almost came to a halt. HTTP requests were slow or wouldn't go through at all, SSH would work, but would take 30+ seconds to register keystrokes, etc.. So we pull up Munin and the only thing that's out of normal boundaries is the Mysql thread count. CPU usage was under 1%, load was under 1.0, plenty of available RAM. As mentioned before, the thread count floats around 2 to 4. At the time of our slow downs it had spiked to 14. So I start poking around the Internet and I see that in most cases, you'll start to see a higher thread count when you start running into slow queries. If I understand it correctly, the request comes in that takes a while to process, in the mean time other requests are coming in, so a new thread will be created to work on the request (yes?). But at the time of the slow down, we had 0 slow queries. My question is: What else can cause mysql to create additional threads. And would this sudden spike in threads possibly cause the server to slow down? To fix the issue, we restarted apache and everything went back to it's beautiful, normal self. Considering the the Server Vitals (CPU, RAM, Network, etc) were all ideal, and the thread count was the only thing out of place, this seems like the most logical thing to pursue as the possible cause. If it matters, we're on Mysql 5.1.40. Server is FreeBSD 7.2 and the server in question is inside a jail.

  • configuring lighttpd for large downloads

    - by ahmedre
    i run a web site that hosts pages that are just general scripts (php, etc) and mp3 downloads (some of which are fairly large - up to 200mb). i am running lighttpd on the servers on linux (ubuntu 64). everything is fine, but under high load, the server is not accessible (or very slow - even sshing in takes a while), and i am guessing this is due to a huge number of mp3 downloads at that time. consequently, dns sees the server as down and redirects all the traffic to the other servers, and after a while, it comes back up and things work again. so what's the best way to fix this? ideally, i want the server to continue running (and the web pages - php etc - to always work, but downloads don't always have to work). should i just have 2 web servers running (one for the downloads and one for the php pages), or is it perhaps something i can fix in my lighttpd configuration? here are the snippets from my configuration: server.max-worker = 4 server.max-fds = 2048 server.max-keep-alive-requests = 4 server.max-keep-alive-idle = 4 server.stat-cache-engine = "fam" fastcgi.server = ( ".php" => (( "bin-path" => "/usr/bin/php-cgi", "socket" => "/tmp/php.socket", "max-procs" => 1, "idle-timeout" => 20, "bin-environment" => ( "PHP_FCGI_CHILDREN" => "64", "PHP_FCGI_MAX_REQUESTS" => "1000" ), "bin-copy-environment" => ( "PATH", "SHELL", "USER" ), "broken-scriptfilename" => "enable" )) ) # normal php site $HTTP["host"] =~ "bar.com" { server.document-root = "/usr/local/www/sites/bar.com/" accesslog.filename = "|/usr/sbin/cronolog /var/log/lighttpd/%m/%d/%H/bar.log" } # download site $HTTP["host"] =~ "(download|stream).foo.com" { server.document-root = "/home/audio/" dir-listing.activate = "enable" dir-listing.hide-dotfiles = "enable" evasive.max-conns-per-ip = 1 evasive.silent = "enable" # connection.kbytes-per-second = 256 accesslog.filename = "|/usr/sbin/cronolog /var/log/lighttpd/%m/%d/%H/download.log" }

  • MySQL getting stuck, eating up disk i/o

    - by bonez05
    Hi all, Using mySQL 5.0.51 on Solaris . At intermittent times it looks like MySQL is getting 'stuck' . The disk usage on the server spikes to 98% busy from reads. I used dtrace (specifically DTrace toolkit - iosnoop) to track down what processes was using all the reads. Mysql was calling tablename.TDM hundreds of times per second. There was no more than average load on the webserver that could account for this. There were no cronjobs running, and no other utilities like mysqldump or anything. It is a master / slave replication setup. As a jury-rigged fix, I altered the mysql table from 'tablename' to 'tablename2' and then back to 'tablename' This fixed the problem temporarily, and "unsticks" mysql. The disk usage goes back down and dtrace is no longer showing hundreds of reads to 'tablename.TDM' / second. A couple ideas I had are: 1. MySQL version bug 2. Infinite loop somewhere in my application (which i'm not sure how likely this is) 3. ?? Has anybody seen this before or have any insight? Thanks
