How to Update Red Hat Enterprise Linux 5.4 using CentOS Repos

I don't have a subscription for RHEL anymore and I want to update my server. Can anyone tell me How to Update Red Hat Enterprise Linux 5.4 using CentOS Repos ?

Solution 1:

Ok i figured out. I created a file CentOs.repo (/etc/yum.repos.d/CentOs.repo) with the following contents :

[CentOS-Base]
name=CentOS-Base
mirrorlist=http://mirrorlist.centos.org/?release=5&arch=$basearch&repo=os
gpgcheck=1
enabled=1
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5

[CentOS-Updates]
name=CentOS-Updates
mirrorlist=http://mirrorlist.centos.org/?release=5&arch=$basearch&repo=updates
gpgcheck=1
enabled=1
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5

[CentOS-Plus]
name=CentOS-Plus
mirrorlist=http://mirrorlist.centos.org/?release=5&arch=$basearch&repo=centosplus
gpgcheck=1
enabled=1
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5

Solution 2:

IIRC, you just install the approprate centos-release package, and then run yum upgrade (or yum update if you don't want to obsolete anything).
