• Moving MySQL directory on an Amazon EC2 machine

  - by Traveling Tech Guy

  I'm trying to have MySQL point to a directory on an EBS volume I mounted on my EC2 machine. I took th following steps: Stopped MySQL (/etc/init.d/mysqld stop) - successful Created a MySQL directory on my volume, mounted on /vol (mkdir /vol/mysql) Copied the contents of /var/lib/mysql to /vol/mysql (cp -R /var/lib/mysql /vol/mysql) Chanded the owner and group of that directory to match the original (chown -R mysql:mysql /vol/mysql) - after this step, the 2 directories are identical. Edited the /etc/my.cnf file (commented 2 original lines): [mysqld] #datadir=/var/lib/mysql #socket=/var/lib/mysql/mysql.sock datadir=/vol/mysql socket=/vol/mysql/mysql.sock` Started MySQL (/etc/init.d/mysqld start) - FAILED The error file /var/log/mysqld.log contains the following lines: 100205 20:52:54 mysqld started 100205 20:52:54 InnoDB: Started; log sequence number 0 43665 100205 20:52:54 [Note] /usr/libexec/mysqld: ready for connections. Version: '5.0.45' socket: '/vol/mysql/mysql.sock' port: 3306 Source distribution No other errors are available. What am I doing wrong? Where can I find the error/s encountered by MySql? If I restore the original lines, MySQL starts, leading me to believe it may be a permissions issue - but permissions are the same for both directories? Thanks!

• Sensitive data deletion (remote)

  - by José Antonio Silva

  Hi, I'm just finished my Amazon EC2 migration and I want to delete all the files (databases, source code) from the old servers. The problem is that the servers are in California and my business is in Chile, soo I only have ssh access to that servers. I'm planning to sell the servers and I'm wondering if there is a way to perform a low levele deletion remotely of the specific files and folders. Thanks in advance! José Antonio

• See all output from commands performed inside screen

  - by user1032531

  I am using screen (http://www.gnu.org/software/screen/manual/screen.html) to access my minecraft console. I created a server in /etc/init.d, and have minecraft running in the background. Then, to access the minecraft console, I just type # screen -r in bash. I can now do commands in the screen shell. The problem is if I do some command which exports a bunch of text, it exceeds the size of the screen and pushes the begging output off the page. And I cannot seem to scroll up and see it. How can I scroll back and view all the output? How can I pause the output (maybe something like more or less)?

• Increase text size in Ubuntu due to having large resolution/monitors

  - by Sridhar Ratnakumar

  I have 24" dual monitors with 1920x1080 resolution on both of them. Consequently the text appears so small. I use the following text-intensive applications frequently: Web browser (Google Chrome) IDE (Komodo) Terminal (Gnome Terminal) Email (Thunderbird) I can configure text size on IDE, Terminal and Email. But for Chrome, it is not a good idea to set proportional font size because often one wants to see the entire (not just proportional fonts) site to be zoomed. So I am asking: Is it possible to increase DPI in Ubuntu (much like on Windows) so as to increase the text size across all apps? OR Is it possible to set permanent 'zoom' in Google Chrome, using a third-party extension maybe?

• Installing sqlite gem fails on AWS Linux instance with sqlite-devel libraries installed

  - by Scott

  Hi, I'm running an instance built off ami-595a0a1c. I am trying to install the sqlite3 (or sqlite) gem and it's failing with the below error: $ sudo gem install sqlite3 Building native extensions. This could take a while... ERROR: Error installing sqlite3: ERROR: Failed to build gem native extension. /usr/bin/ruby extconf.rb checking for sqlite3.h... no sqlite3.h is missing. Try 'port install sqlite3 +universal' or 'yum install sqlite3-devel' and check your shared library search path (the location where your sqlite3 shared library is located). extconf.rb failed * Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers. Check the mkmf.log file for more details. You may need configuration options.

Results logged to /usr/lib64/ruby/gems/1.8/gems/sqlite3-1.3.3/ext/sqlite3/gem_make.out Typically, this just means you need to install the development libraries and everything is cool. However, I have installed the sqlite-devel packages and still no dice. Since this is the Amazon Linux instance, I'd rather not add more repositories than the ones Amazon provides if possible. What can i do to get this thing to compile? Thanks for any insight! From a brand new instance, here's what I've done: $ sudo yum install rubygems ruby-devel $ sudo gem update --system $ sudo gem install rails $ rails new app $ cd app $ rails server Could not find gem 'sqlite3 (= 0)' in any of the gem sources listed in your Gemfile. $ sudo yum install sqlite-devel $ sudo gem install sqlite (or sqlite3 -- same result) See breakage above

• samba 3.5 "force user" doesn't seem to be sticking

  - by myCubeIsMyCell

  After installing a new OS with newer version of samba, I'm having trouble accessing my shares. I can browse to the specific share, but only to the top level. As best I can tell from the logs, it seems the "force user" in the samba config isn't sticking beyond the initial connection. Details below. I installed a new version of CentOS on my storage server. My old CentOS (4?)install had samba version 3.0.33, new CentOS is using 3.5.10. No domain/AD involved ... just home workgroup. no real security... just some shares hidden & some defined as read-only. here's my config: [global] workgroup = WORKGROUP server string = Samba Server Version %v netbios name = luna security = share # logs split per machine log file = /var/log/samba/log.%m log level = 2 # max 50KB per log file, then rotate max log size = 50 winbind use default domain = Yes [strge] comment = please path = /storage browseable = yes read only = no force user = windowsguest force group = users guest ok = yes So... the problem I'm running into is that the 'force user' only seems to hold for the initial connection & I see all the top level folders fine. When I drill into a folder I get access denied - which appears to be due to my windows user info being sent (trys to authenticate xuser - a non-existant user to samba, so maps to nobody & fails). Here's the smb error msg: [2012/11/29 14:30:27.326195, 2] auth/auth.c:314(check_ntlm_password) check_ntlm_password: Authentication for user [xuser] -> [xuser] FAILED with error NT_STATUS_NO_SUCH_USER [2012/11/29 14:30:27.326251, 2] auth/auth.c:314(check_ntlm_password) check_ntlm_password: Authentication for user [nobody] -> [nobody] FAILED with error NT_STATUS_NO_SUCH_USER Most of the top level directories are 755, some 777. Either way, can not access them. If I do a chown -R windowsguest.users ... no change... but if I do a chmod -R to 777 or 755 they become browsable... but still can't create files (even for 777 ones). Not sure what role it plays if any... but had to recreate the user windowsguest under the new os install, uid & gid match old user. Seems the main issue as far as I can tell is that samba isn't maintaining the 'force user' - but I could be wildly off base. Client OS is win7 pro x64. Thanks for any suggestions or advice!

• Backup Xen domU machines while running.

  - by Jonathan Hawkes

  The host machine is running CentOS 5.3 and using LVM to create Logical Volumes (LVs) and to allow live snapshots to be taken of those LVs. My thought was to store all of the image files for the Xen underpriviledged domains (domU) in a single LV and periodically take a snapshot of that LV and copy the disk images out of the snapshot in order to make a live backup of these systems. Is this doable? Is there a better way? Thanks!

• Is using Capistrano for user maintenance tasks on university lab feasible?

  - by danielkza

  I've been looking around for tools to replace some legacy scripts for creating and maintaining accounts in a university computer lab ecosystem consisting of things like: LDAP and Kerberos for authentication User home storage and web pages Entries on an SQL database Printing quotas Mailing lists, etc. I'd also like to automate machine and VM membership for Kerberos and Puppet if possiible. I've found Capistrano, and while the basic principle of running tasks on remote hosts through SSH seems to fit, and the DSL in Ruby looks quite nice, I've found most documentation is related to application deployment, not generic tasks. I'm also not aware of any good way to parameterize tasks so I can pass on the user information for creation. Is something about Capistrano I am missing, or is it not the correct tool for this job? Are there any more userful alternatives?

• OpenSSH does not accept public key?

  - by Bob

  I've been trying to solve this for a while, but I'm admittedly quite stumped. I just started up a new server and was setting up OpenSSH to use key-based SSH logins, but I've run into quite a dilemma. All the guides are relatively similar, and I was following them closely (despite having done this once before). I triple checked my work to see if I would notice some obvious screw up - but nothing is apparent. As far as I can tell, I haven't done anything wrong (and I've checked very closely). If it's any help, on my end I'm using Cygwin and the server is running Ubuntu 12.04.1 LTS. Anyways, here is the output (I've removed/censored some parts for privacy (primarily anything with my name, website, or its IP address), but I can assure you that nothing is wrong there): $ ssh user@host -v OpenSSH_5.9p1, OpenSSL 0.9.8r 8 Feb 2011 debug1: Connecting to host [ipaddress] port 22. debug1: Connection established. debug1: identity file /home/user/.ssh/id_rsa type 1 debug1: identity file /home/user/.ssh/id_rsa-cert type -1 debug1: identity file /home/user/.ssh/id_dsa type -1 debug1: identity file /home/user/.ssh/id_dsa-cert type -1 debug1: identity file /home/user/.ssh/id_ecdsa type -1 debug1: identity file /home/user/.ssh/id_ecdsa-cert type -1 debug1: Remote protocol version 2.0, remote software version OpenSSH_5.9p1 Debian-5ubuntu1 debug1: match: OpenSSH_5.9p1 Debian-5ubuntu1 pat OpenSSH* debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_5.9 debug1: SSH2_MSG_KEXINIT sent debug1: SSH2_MSG_KEXINIT received debug1: kex: server->client aes128-ctr hmac-md5 none debug1: kex: client->server aes128-ctr hmac-md5 none debug1: sending SSH2_MSG_KEX_ECDH_INIT debug1: expecting SSH2_MSG_KEX_ECDH_REPLY debug1: Server host key: ECDSA 24:68:c3:d8:13:f8:61:94:f2:95:34:d1:e2:6d:e7:d7 debug1: Host 'host' is known and matches the ECDSA host key. debug1: Found key in /home/user/.ssh/known_hosts:2 debug1: ssh_ecdsa_verify: signature correct debug1: SSH2_MSG_NEWKEYS sent debug1: expecting SSH2_MSG_NEWKEYS debug1: SSH2_MSG_NEWKEYS received debug1: Roaming not allowed by server debug1: SSH2_MSG_SERVICE_REQUEST sent debug1: SSH2_MSG_SERVICE_ACCEPT received debug1: Authentications that can continue: publickey debug1: Next authentication method: publickey debug1: Offering RSA public key: /home/user/.ssh/id_rsa debug1: Authentications that can continue: publickey debug1: Trying private key: /home/user/.ssh/id_dsa debug1: Trying private key: /home/user/.ssh/id_ecdsa debug1: No more authentication methods to try.

• nginx + varnish + apache differente IPs in VirtualHost Apache

  - by zeusgod

  Hi, My idea is put NGINX as proxy to redirect to Varnish (cache static content) and then proxy to apache with a lot of VirtualHost in different IPs. My problems is that I would know how can configure Varnish to send access to correct IP, I am going explain: NGINX: Listen in: 10.10.10.10, 20.20.20.20 and 30.30.30.30 on ports: 80 and 443 Proxy redirect to Varnish 10.10.10.10:8080, 20.20.20.20:8080 and 30.30.30.30:8080 Varnish: Port: 8080 - THIS IS THE PROBLEM Proxy content not static to Apache on port 8000 - THIS IS THE OTHER PROBLEM Apache2: Listen in: 10.10.10.10:8000, 20.20.20.20:8000 and 30.30.30.30:8000 Response correct VirtualHost This is the idea. When I try with one IP only, all work correctly, because Varnish is only listen in one IP and port and send to backend in one IP and port too. Could you help me to configure Varnish or there is a best way to configure similar scenario please?

• Open a file with eclipse via terminal and focus eclipse window

  - by Rui Carneiro

  I am a webdeveloper and my current working tools are: Terminal (ssh, tailing logs, grep, git, etc) Eclipse (PDT, Javascript, etc) Firefox (Developer Toolbar + Firebug) The problem is that I hate using the eclipse navigation tree. For me it is a lot easier to go to the Terminal and do something like this: $ eclipse /var/www/myproject/long/path/lib/Driver/Sql.php The annoying part is that the eclipse window is not focused after this command. I have to manually click on the eclipse window (using mouse... :@ grrr) Anyway to force eclipse to be focused?

• NIS user not being added to NIS group

  - by Brian

  I have set up a NIS server and several NIS clients. I have a user and a group on the NIS server like so: /etc/passwd: myself:x:5000:5000:,,,:/home/myself:/bin/bash /etc/group: fishy:x:3001:otheruser,etc,myself,moreppl I imported the users and groups on the NIS client by adding +:::::: to /etc/passwd and +::: to /etc/group. I can log in to the NIS client, but when I run groups, fishy is not listed. But getent group fishy shows that it was imported correctly and lists me as a member. And if I do sudo su - myself, then suddenly groups says I am in the group! I also had nscd installed, and the groups worked correctly for a while. It seemed like after being logged in for a while, I would silently be dropped out of the group. If I restarted nscd and logged in again, then the groups worked correctly...for a while. There are no UID or GID conflicts with local users or groups. Update: Contents of /etc/nsswitch.conf: passwd: compat group: compat shadow: compat hosts: files nis dns networks: files protocols: db files services: db files ethers: db files rpc: db files netgroup: nis aliases: nis files

• OpenAFS on Fedora/CentOS

  - by Michael Pliskin

  I am trying to see if OpenAFS fits my needs as a distributed filesystem and is a bit stuck. There are docs but they're all quite hard to understand, so asking for some expert advice here. My questions: which version to install? I need windows client support so I need 1.5 - right? But it is not stable.. Or is it? And don't see any pre-built rpms for it, so compiling from sources? tried to compile and it worked but it created a non-"mp" kernel module while my kernel needs an mp one - how to workaround that? do I really need a new fresh partition to start with or I can re-use an existing one and just make it available via afp? any nice HOWTOs around?

• Can you have more than one ~/.ssh/config file?

  - by DrewVS

  We have a bastion server that we use to connect to multiple hosts, and our .ssh/config has grown to over a thousand lines (we have hundreds of hosts that we connect to). This is beginning to get a little unwieldy and I'd like to know if there is a way to break the .ssh/config file up into multiple files. Ideally, we'd specify somewhere that other files would be treated as an .ssh/config file, possibly like: ~/.ssh/config ~/.ssh/config_1 ~/.ssh/config_2 ~/.ssh/config_3 ... I have read the documentation on ssh/config, and I don't see that this is possible. But maybe someone else has had a similar issue and has found a solution.

• How to use HTML markup tags inside Bash script

  - by CONtext

  I have crontab and a simple bash script that sends me emails every often containing PHP, NGINX, MYSQL errors from their log files. This is a simplified example. #/home/user/status.sh [email protected] PHP_ERROR=`tail -5 /var/log/php-fpm/error.log` NGINX_ERROR=`tail -5 /var/log/nginx/error.log` MYSQL_ERROR=`tail /var/log/mysqld.log` DISK_SPACE=`df -h` echo " Today's, server report:: ================================== DISK_SPACE: $DISK_SPACE --------------------------------- MEMORY_USAGE: $MEMORY_USAGE ----------------------------------- NGINX ERROR: $NGINX_ERROR ----------------------------------- PHP ERRORS: $PHP_ERROR ------------------------------------ MYSQL_ERRORS: $MYSQL_ERROR ------------------------------------- " | mail -s "Server reports" $EMAIL I know this is a very basic usage, but as you can see, I am trying to separate the errors, but not of the html tags including \n are working. So, my question is, is it possible to use HTML tags to format the text, if not .. then what are the alternatives.

• Why a SIGHUP signal to httpd kills the tomcat process?

  - by Geo

  I have a server with a tomcat process binding to port 80 and a httpd processes binding to port 5000. For some reason every time any process send a SIGHUP signal to httpd process my tomcat process disappears without error or anything. I fixed the issue on the server the following way, added an explicit ServerName directive in the httpd.conf and that fixed the issue. I still don't understand why the SIGHUP to httpd killed the tomcat process. NOTE 1: I replicated the kill signal with the following command: find out what the httpd pid is. cat /etc/httpd/run/httpd.pid 4056 then kill with a sighup signal kill -s SIGHUP 4056 NOTE 2: We troubleshoot the issue and find that logrotate running every morning at 4am was sending a SIGHUP signal to realease the logs to be able to rotate them, thus killing tomcat as well.

• IPvsadm not equally balancing on wlc scheduler

  - by davidsmalley

  For some reason, ipvsadm does not seem to be equally balancing the connections between my real servers when using the wlc or lc schedulers. One real server gets absolutely hammered with requests while the others receive relatively few connections. My ldirectord.cf file looks like this: quiescent = yes autoreload = yes checktimeout = 10 checkinterval = 10 # *.site.com http virtual = 111.111.111.111:http real = 10.10.10.1:http ipip 10 real = 10.10.10.2:http ipip 10 real = 10.10.10.3:http ipip 10 real = 10.10.10.4:http ipip 10 real = 10.10.10.5:http ipip 10 scheduler = lc protocol = tcp service = http checktype = negotiate request = "/lb" receive = "Up and running" virtualhost = "site.com" fallback = 127.0.0.1:http The weird thing that I think may be causing the problem (but I'm really not sure) is that ipvsadm doesn't seem to be tracking active connections properly, they all appear as inactive connections IP Virtual Server version 1.2.1 (size=4096) Prot LocalAddress:Port Scheduler Flags -> RemoteAddress:Port Forward Weight ActiveConn InActConn TCP 111.111.111.111:http lc -> 10.10.10.1:http Tunnel 10 0 10 -> 10.10.10.2:http Tunnel 10 0 18 -> 10.10.10.3:http Tunnel 10 0 3 -> 10.10.10.4:http Tunnel 10 0 10 -> 10.10.10.5:http Tunnel 10 0 5 If I do ipvsadm -Lnc then I see lots of connections but only ever in ESTABLISHED & FIN_WAIT states. I was using ldirectord previously on a Gentoo based load balancer and the activeconn used to be accurate, since moving to Ubuntu 10.4 LTS something seems to be different. # ipvsadm -v ipvsadm v1.25 2008/5/15 (compiled with popt and IPVS v1.2.1) So, is ipvsadm not tracking active connections properly and thus making load balancing work incorrectly and if so, how do I get it to work properly again? Edit: It gets weirder, if I cat /proc/net/ip_vs then it looks like the correct activeconns are there IP Virtual Server version 1.2.1 (size=4096) Prot LocalAddress:Port Scheduler Flags -> RemoteAddress:Port Forward Weight ActiveConn InActConn TCP B86A9732:0050 rr -> 0AB42453:0050 Tunnel 10 1 24 -> 0AB4321D:0050 Tunnel 10 0 23 -> 0AB426B2:0050 Tunnel 10 2 25 -> 0AB4244C:0050 Tunnel 10 2 22 -> 0AB42024:0050 Tunnel 10 2 23

• Files listed by bash but unaccessible

  - by Cerin

  What would cause the following behavior on an Ubuntu 12.04 system? I've SSHed into a machine as the "ubuntu" user. Running ls -lah /data/* shows dozens of non-empty files (e.g. file1.txt, file2.txt, etc), all owned by the "ubuntu" user/group, and with full read/write access. If I try to cat /data/file1.txt, bash gives me the error "cat: /data/file1.txt: No such file or directory" In short, ls is listing files, but in every other way, the files essentially don't exist. I can't cat them or read them in any way. Even giving all the files 777 permission doesn't change anything. This is really bizarre. What's going on here?

• NFSv3 + ACL: mask is gone on clients

  - by Jorge Suárez de Lis

  I'm sharing a NFS folder among a user group. The default umask on the clients is 0700, and this is a problem because newly created files won't be readable/writable by another users. So, I'm using ACLs to force the umask 0770 on the shared folder, and this works OK on the server, but not on the clients. server # getfacl /export/proyectos getfacl: Eliminando «/» inicial en nombres de ruta absolutos # file: export/proyectos # owner: root # group: root user::rwx group::rwx other::r-x default:user::rwx default:group::rwx default:mask::rwx default:other::r-x server # getfacl /export/proyectos/innovacion getfacl: Eliminando «/» inicial en nombres de ruta absolutos # file: export/proyectos/innovacion # owner: root # group: proyecto-innovacion # flags: ss- user::rwx group::rwx mask::rwx other::--- default:user::rwx default:group::rwx default:mask::rwx default:other::--- As you see, the default (and also a specific on the second directory) mask ACLs are being applied. I mount the whole share on the client: 172.16.54.56:/export/proyectos on /proyectos type nfs (rw,noatime,rsize=131072,wsize=131072,acregmin=10,acl,nfsvers=3,addr=172.16.54.56) But the mask and default:mask ACLs are gone. client $ getfacl /proyectos/ getfacl: Eliminando «/» inicial en nombres de ruta absolutos # file: proyectos/ # owner: root # group: root user::rwx group::rwx other::r-x default:user::rwx default:group::rwx default:other::r-x client $ getfacl /proyectos/innovacion getfacl: Eliminando «/» inicial en nombres de ruta absolutos # file: proyectos/innovacion # owner: root # group: proyecto-innovacion # flags: ss- user::rwx group::rwx other::--- default:user::rwx default:group::rwx default:other::--- It lacks the default:mask and mask ACLs, the only ones that I've setted. So the proposed solution to enforce umask won't work for me. Why is happening this?
