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.
