CentOS 5.8发布了。CentOS 是一个企业级的 Linux 发行版本，它源于上游操作系统提供者免费公开的源代码。CentOS 完全遵守上游供应商的再发行政策，并且以百分之百的软件兼容性为目标。
CentOS（Community ENTerprise Operating System）是Linux发行版之一，它是来自于Red Hat Enterprise Linux依照开放源代码规定释出的源代码所编译而成。由于出自同样的源代码，因此有些要求高度稳定性的服务器以CentOS替代商业版的Red Hat Enterprise Linux使用。两者的不同，在于CentOS并不包含封闭源代码软件。
