CentOS 5.3 Released

For those who might not be familiar with enterprise linux distributions, CentOS is a rebranded free version of Red Hat Enterprise Linux (RHEL). For enterprise usage Red Hat supports each release for 7 years, while carefully updating packages for backwards compatibility. Each .1 “point release” is an Service Pack update. RHEL 5.3 was released at the end of January.

Typically it takes a few weeks for the CentOS team to repackage, build and distribute the source of RHEL into a CentOS release. Last night CentOS 5.3 release was announced. The seemingly long delay was due primarily to some personal issues within the CentOS team.

I have been running a personal server on CentOS for 1 year now and I could not be more pleased with the results. I plan to update my server tonight when I am at the console. The following are some tips I’ve read online for a smooth (and fast) upgrade:

# yum update glibc

The glibc update is due to a RHEL 5.3 known issue.

After that, I would generally do the following. This basically updates the YUM installation system first to take advantage of any improvements in a newer YUM release. :

# yum update yum rpm
# yum clean all
# yum -y update

Even though past updates have been flawless for me, please do make proper backups, and read the Release Notes for more information.


  1. uhm … I did a simple 3 steps routine

    1) yum clean all

    2) yum check-update

    3) yum upgrade

    the only problem I got is with the 5.3 kernel, which goes in panic after the reboot …

  2. @kOoLiNuS:

    Most people did a simple yum update with no problems.

    Odd, I remember that for 5.2 on certain hardware. What Hw is this? I didn’t see any listing of panics on the mailing list. Have you checked the forums?

  3. hadn’t the time …. serious personal problems at home so in those days I’m just keeping up the minimum of our server availability …

    ASAP i’ll post a screenshot of the error and start investigating on it, promised ;-)
