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:

[main]
exclude=mod_ssl* httpd* perl mysql* php* #this is mainly for cpanel servers
cachedir=/var/cache/yum
debuglevel=2
logfile=/var/log/yum.log
pkgpolicy=newest
distroverpkg=redhat-release
tolerant=1
exactarch=1

[base]
name=CentOS-$releasever - Base
baseurl=http://beta.centos.org/centos/$releasever/os/$basearch/
gpgcheck=1

#released updates
[update]
name=CentOS-$releasever - Updates
baseurl=http://beta.centos.org/centos/$releasever/updates/$basearch/
gpgcheck=1

#packages used/produced in the build but not released
[addons]
name=CentOS-$releasever - Addons
baseurl=http://beta.centos.org/centos/$releasever/addons/$basearch/
gpgcheck=1

#additional packages that may be useful
[extras]
name=CentOS-$releasever - Extras
baseurl=http://beta.centos.org/centos/$releasever/extras/$basearch/
gpgcheck=1

#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
#[centosplus]
#name=CentOS-$releasever - CentOSplus
#baseurl=http://beta.centos.org/centos/$releasever/centosplus/$basearch/
#gpgcheck=1

#packages in testing
#[testing]
#name=CentOS-$releasever - Testing
#baseurl=http://beta.centos.org/centos/$releasever/testing/$basearch/
#gpgcheck=1

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.
