RHEL to CentOS
Contents
I installed RHEL today, but to get updates (via yum), a subscription is required. Not CentOS however.
Some Google-ing uncovered this article, which pretty much works, except I had to make a few edits here and there.
# Remove cached packages
yum clean all
# Create /root/centos/
mkdir ~/centos && cd ~/centos
# Import CentOS's GPG key
wget http://mirror.centos.org/centos/5.4/os/i386/RPM-GPG-KEY-CentOS-5
rpm --import RPM-GPG-KEY-CentOS-5
# Download packages
wget http://mirror.centos.org/centos/5.4/os/i386/CentOS/centos-release-5-4.el5.centos.1.i386.rpm
wget http://mirror.centos.org/centos/5.4/os/i386/CentOS/centos-release-notes-5.4-4.i386.rpm
wget http://mirror.centos.org/centos/5.4/os/i386/CentOS/yum-3.2.22-20.el5.centos.noarch.rpm
wget http://mirror.centos.org/centos/5.4/os/i386/CentOS/yum-fastestmirror-1.1.16-13.el5.centos.noarch.rpm
wget http://mirror.centos.org/centos/5.4/os/i386/CentOS/yum-updatesd-0.9-2.el5.noarch.rpm
# Install 'em
rpm -Uvh {centos,yum}*.rpm
# Erase RHN-related packages
rpm -e --nodeps redhat-release
rpm -e --nodeps yum-rhn-plugin
# Profit!
yum upgrade
At this moment, my download is progressing nicely, thanks to NUS’s mirror.
