Free Linux - Free Red Hat Enterprise Linux from Community Enterprise Operating System

free red hat enterprise linux Centos provides a free enterprise class computing Linux platform to anyone who wishes to use it.

The Free Enterprise Linux from Centos is built from publicly available open source SRPMS provided by a prominent North American Enterprise Linux vendor. CentOS conforms fully with the upstream vendors redistribution policies and aims to be 100% binary compatible.
Usually, an updated version of the Centos Enterprise Linux is available within 72 hours of Red Hat releasing a fix in their enterprise version.

So effectively, the Centos Linux is as good as a free Red Hat Enterprise Linux .

You can download your copy from the Centos website . For updates & upgrades, CentOS ships with an application called yum that serves as our recommended tool for performing updates and package installation. Please see this guide for Managing software with Yum

You can also make contributions to Centos (C ommunity ENT erprise O perating S ystem).

Note: CentOS Project or any version of CentOS is not affiliated with, produced by, or supported by the prominent North American Enterprise Linux vendor. Neither does the Centos Free Linux software contain the upstream vendor’s product, although it is built from the same open source SRPMS as the Red Hat’s upstream enterprise products.
