Server :: CentOS 5.3 - Easiest Way To Keep Software Updated?
Mar 17, 2010
I have somewhere between 8 and 12 servers, spread amongst different webhosts, all running CentOS 5.3. Everything on the servers has been compiled from source:
> EngineX, PHP, MySQL, Munin, etc
I compile from source because I usually run ./configure to modify the source before installing. What would be the easiest way to keep the server software updated? I am considering creating custom packages from a server which I would keep up to date manually. Then use Capistrano or Puppet to install those packages on all of my servers.

We have two CentOS 5 servers in production (web and database). We are setting up a single staging server that will mirror the configurations of these servers as closely as possible. What is the easiest way to ensure the exact same software and configs as the production servers are setup on the new staging server. Our contracted data center provider has already informed us that they do not perform images and NO we do not have physical access to the machines. It is undetermined whether we will be virtualizing the staging server into two virtual servers yet, so for the purposes of this post lets assume we are not. I'm seeking a faster/more precise method than doing this by eye and hand.
Some information on our web server code...

I have installed CentOS 5.3 with Xen on a PowerEdge 2650 machine with 6GB of RAM. As usual, PAE was already enabled so I did not have any problem with utilising all of the memory. However after upgrading to the latest release of the kernel (2.6.18-128.7.1.el5xen), memory available decreased to 4GBs. Then I switched back to the old kernel and 6GB was there. Then finally have switched back to the new kernel and 6GB is again there. So now PAE seems to be enabled but what concerns me is the inconsistent behaviour. (Also I am not sure the reason was the upgraded kernel.)

I'm in the middle of moving my lab to a new server in the middle of the school year.. and need to copy all the user accounts to the new box, hopefully with all the student's passwords and contents of their folders intact.And since we are using the system daily, I need to do it all in an hour or 2.I'm thinking I can just
1. diff /etc/passwd and /etc/shadow from the old the new
2. copy all the student folders to new /home
3. write a script to set the permissions on all the new /home folders to match the user names.
It seems easy and safe so long as I back up the 2 existing files..Any reason not to try? Or is there an easier way?

I need to setup a mail server, purely for relaying mail to a MS exchange server. A previous employee used Postfix on CentOS. I have limited Linux knowledge and no experience with any mail server software other than MS Exchange, so we cannot continue with this solution (unless I can find a way of managing it all from a gui). Does anyone know of an MTA that can be configured completely by GUI? Everyone says sendmail has millions of features and loads of documentation, but I simply do not have the time to learn it. I need something that can be configured with minimal knowledge and via GUI, not command line. The only reason I'm not using Exchange is to try to save money, and hopefully it will be more secure.

I have like over 60 gb of tons and tons of tiny tiny files.
I used
Code:
rm -rf *
and I ended with system load of over 100+.
Any idea how do I mass remove the files without crashing the system? I have Q9550 with 8 gb ram.

Are there programs for this? Really really simple page layouts that you can edit and host from a graphical desktop that has your web browsers and Pidgen and VLC media player and everything running on it at the same time?

I have a copy of the DVD Iso for centos 5.3. I downloaded the updated packages to the Centos directory and then ran the repomanage perl script to remove the old files from the directory. I then ran the createrepo and the new iso image with the script code below.
baseDir=`pwd`
rhelBuild=`pwd`/dvd-iso-contents
rm -f CentOS_1.0.0.iso
echo "Updating repository"
dvd_discinfo=`head -1 $rhelBuild/.discinfo`
echo "$dvd_discinfo
[Code]...
I am using VMWare to test the build, so I have the cd pointing to the iso image. I get the CentOS to start up find and dandy asking the questions for the interactive boot. It gets thru the stage of checking dependencies and then when it starts to copy down the image to the "harddrive" that is when the problem occurs.
One of the updated files is file-4.17-15.el5_3.1.i386.rpm (file-4.17-15.el5.i386.rpm was removed using repomanage), but the loader is looking for the removed file. I've looked thru any dependencies, but nothing specific for the removed file, all are asking for /usr/bin/file with no specific version numbers. I have run a rpm -test on all the rpms, but haven't been able to look thru that to see if there is a specific request for the version.
I did try this, but it just moved on to the next file. I did not replace the file version, but then it found another problem that was the same as this, the updated file is in the repo, but it is requesting the old version. I looked thru the fileslist and others to see if maybe that was the problem, but they were updated to the new versions.

I'm guessing Red Hat (and therefor Centos) backport programs like newer Open Offices. Is this true? If so, is there a list of programs that they maintain actively?

I came to a "weird" situation when I saw in yum log files that several centOS systems have been automatically updated via yum. I checked the following:
1. chkconfig for init services that could upgrade the system: only yum-updatesd
2. In the config file of yum-updatesd.conf the do_update function is set to no.
3. If an updated made manually by a user ..no.
Where else should I look or how this update happened?

I haven't updated my centos box for almost about a year, my theory is if it ain't broke don't fix it.These last two weeks I've been replacing hardware, a motherboard, memory, processor, and a hard-disk. Everything worked fine with the current 2.6.18-128.1.10, but I decided that I should upgrade to the latest along with all the new packages. But in doing so I would need to recompile the driver module for the raid controllers, rr1740. So I recompiled them using the 2.6.18-164.1 build while I was in kernel 128. When I was done, I restarted the machine and when it booted to the new 164 kernel, it came back very long error messages but here's what I can remember off the top of my head.

What is the best place to get an updated nVidia video driver for CentOS 5.5? Is there a CentOS package available that will update it? Or is it best to download it directly from nVidia? Also, I do not have an internet connection on the machine, so it will have to be a manual download and installation.

When I run yum list installed command the output shows two kernels:
[Code].....
Would it therefore be safe to remove the first kernel in the installed list to save having two kernels being updated everytime I run yum update? Or is the PAE kernel dependant upon the original?

want to sync 2 folders, one on a desktop and the other on my server. My objective is to keep the desktop folder always updated with the content of the server folder. If I get this working, I can do the same with the rest of my desktop and laptop users. When online they can run a script with rsync and update data. Is it possible to get 2 way sync?

I have configured master and slave Bind servers. Everything works fine. But whenever I add a new zone entry at master server it is not getting updated at slave server in logs I see this error:
client 192.168.1.1#43428: view external: received notify for zone 'yourdomainname.com': not authoritative
At master server I do not see any error or warning message. This error clearly indicates that named.conf file does not have zone entry in it or domain name is wrong. While checking the named.conf file I see that the zone entry has not been updated at slave server. If I update it manually and reload named on slave then zone files (db files) are getting created without any issue and any modification at master server for the zone records are also getting updated. My concern is why zone record is not getting appended at slave server in named.conf file.
Is there anything I am missing in the configuration. I am pasting the steps which I have followed to configure my master and slave server:
Configure Bind as master and slave server
Install Bind on your server
yum install bind
OR
sudu apt-get install bind9
Generate RNDC Key using the command
rndc-confgen -a -k rndc-key
it will stored in /etc/rndc-key file
Master Server IP 192.168.0.1
Slave Server IP 192.168.1.1
Master Server Configuration
options .....

we're about to migrate a set of workstations (ubuntu 10.04 LTS) to a new kerberos/LDAP setup. Basically, this requires the installation of some required deb packages and to copy some new .conf files over the original ones.We made a deb package having these "features":requires the needed other packages as dependenciesbacks up original conf filescopies the new conf files to the right places (i.e. /etc/krb5.conf,/etc/ldap.conf)The problem is: apt-get complains because the deb is "touching" files owned by other packages (kerberos, ldap, etc.). Therefore, the only way to skip this check is either to force apt-get to proceed or using the "replaces" directive in the deb control file, specifying the clashing packages. omething like this:
Code:
Package: <package-name>
Version: 0.9.9
