Centos是众多Linux发行套件之一。在红帽子对其企业操作系统采取收费的形势后cAos组织开发的CentOS CentOS与RHEL完全兼容，它是基于RHEL的源代码制作而成,而且它还提供一定的支持(完全免费哟)。被誉为社区企业linux操作系统。
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.
