HOWTO: Convert from RHEL 5.3 to CENTOS 5.3
This is actually a lot more simple than I was expecting. Recently our RHEL subscription for a backup server expired and couldn’t really justify the cost to renew it, so I decided to convert it to a CentOS installation by doing the below:
yum clean all mkdir /usr/src/centos cd /usr/src/centos wget http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5 wget http://mirror.centos.org/centos/5/os/i386/CentOS/centos-release-5-3.el5.centos.1.i386.rpm wget http://mirror.centos.org/centos/5/os/i386/CentOS/centos-release-notes-5.3-3.i386.rpm wget http://mirror.centos.org/centos/5/os/i386/CentOS/yum-3.2.19-18.el5.centos.noarch.rpm wget http://mirror.centos.org/centos/5/os/i386/CentOS/yum-updatesd-0.9-2.el5.noarch.rpm wget http://mirror.centos.org/centos/5/os/i386/CentOS/yum-fastestmirror-1.1.16-13.el5.centos.noarch.rpm rpm –-import RPM-GPG-KEY-CentOS-5 /bin/rpm -e --nodeps redhat-release /bin/rpm -e --nodeps rhn-client-tools /bin/rpm -e --nodeps yum-rhn-plugin rpm -Uvh --force *.rpm yum upgrade
How painless was that?!
Thanks for the post. This procedure worked great for me. I can finally get updates again!
Very use post. Well done.
Thanks a ton! Really helped me out. It is so rare to find a clear, step by step instruction(s) out there that actually work. Most of the time the developer assumes the community knows that between step 3 and 4, you were suppose to reboot…. lol
