EPEL Extra Packages for Enterprise Linux is a volunteer-based community effort from the Fedora project to create a repository of high-quality add-on packages for Red Hat Enterprise Linux (RHEL) and its compatible spinoffs such as CentOS or Scientific Linux. Fedora is the upstream of RHEL and add-on packages for EPEL are primarily sourced from the Fedora repository and built against RHEL.

Install EPEL on CentOS:

[root@orca epel]# yum localinstall --nogpgcheck /home/nobody/downloads/epel/epel-release-5-3.noarch.rpm
