Convert RHEL 5.x to Oracle Linux 5.x
Convert RHEL to Oracle Linux
Log on to the RHEL server as the "root" user and remove the existing yum repository files.
cd /etc/yum.repos.d rm *.repo
Download the key and repository file from public-yum.oracle.com.
wget http://public-yum.oracle.com/RPM-GPG-KEY-oracle-el5 -O /etc/pki/rpm-gpg/RPM-GPG-KEY-oracle gpg --quiet --with-fingerprint /etc/pki/rpm-gpg/RPM-GPG-KEY-oracle wget http://public-yum.oracle.com/public-yum-el5.repo
Erase the "rhn-client-tools" package, as this will cause conflicts with "up2date" during the full update.
yum erase rhn-client-tools -y yum update --skip-broken -y yum install up2date -y
Restart the server.
shutdown -r now
The server is now an Oracle Linux server, updated with all the latest packages.
- You need some form of fallback plan in case this goes wrong. In my case, the upgrade was done on a virtual machine, so I had the option of reverting to a snapshot from before the conversion was started.
- It’s possible your installation will have different dependencies, which might need a little more clean-up before the “yum update”. If so, attempt to delete the conflicting packages, then re-install them once the update is complete.
- This was from RHEL5.9 to OL5.11. The move from earlier spins of RHEL may be a little different, but from what I’ve read it should be fine.
- This should be obvious, but you will have to do some testing to make sure the resulting installation is working as expected.
