Upgrading CentOS 3.3 to 3.4 using yum

Upgrading CentOS 3.3 to 3.4 using yum

CentOS is a great alternative to the expensive Red Hat Enterprise Linux 3. CentOS is RHEL 3 built from source, and on all servers we are using it on at Crucial Paradigm we have found it very stable and a great OS to work with. The CentOS 3.4 release is the same as Red Hat Enterprise Linux 3 Release 4 update.

First step, download

rpm -ivh http://mirror.centos.org/centos/3.4/os/i386/RedHat/RPMS/centos-yumcache-3.1-0.20050105.3.noarch.rpm
rpm -Fvh http://mirror.centos.org/centos/3.4/os/i386/RedHat/RPMS/centos-release-3-4.2.i386.rpm
yum update

Your yum config should look something like the following:

exclude=mod_ssl* httpd* perl mysql* php* #this is mainly for cpanel servers

name=CentOS-$releasever – Base

#released updates
name=CentOS-$releasever – Updates

#packages used/produced in the build but not released
name=CentOS-$releasever – Addons

#additional packages that may be useful
name=CentOS-$releasever – Extras

#centosplus repo – updated packages that extend beyond rhel release versions
#run auto update with this repo enabled only if you know you want extended functonality
#name=CentOS-$releasever – CentOSplus

#packages in testing
#name=CentOS-$releasever – Testing

Some users have reported having problems when updating the caching-nameserver package on CentOS 3.3 with cPanel. Please ensure you backup of your /etc/named.conf file before upgrading.
