Below are the source repo definitions I use. Simply create a file called “Centos-Source.repo” (# chmod 644) in /etc/yum.repos.d/ and enable repositories as required (using enabled=1). Please note that this example is for CentOS version 5 and may differ from any official versions out there. I offer no warranty… it just works for me.
