In order to proceed with this “how to” you will need a functional RedHat or RedHat based distribution.

Note: CentOS does not provide commercial support!
“CentOS is an Enterprise-class Linux Distribution derived from sources freely provided to the public by a prominent North American Enterprise Linux vendor. CentOS conforms fully with the upstream vendors redistribution policy and aims to be 100% binary compatible. (CentOS mainly changes packages to remove upstream vendor branding and artwork.) CentOS is free.”
