How To Install Centos 7 in VirtualBox – Linux Dukes

The CentOS Linux distribution is a stable, enterprise-class, predictable, manageable, and reproducible platform derived from Red Hat Enterprise Linux (RHEL) sources.

Since March 2004, CentOS Linux has been a community-supported distribution derived from sources freely provided to the public by Red Hat. As such, CentOS Linux aims to be functionally compatible with RHEL. CentOS Linux is free to use and redistribute.
