CentOS is an open source distribution maintained by a skilled collection of contributors and users. CentOS is 100% compatible with Red Hat Enterprise Linux (RHEL), rebuilt from the RHEL source distribution that is in full compliance with Red Hat's redistribution requirements. CentOS is a community supported project geared toward users that do not require commercial support but do require an enterprise class operating system.
