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.

CentOS-5.1 is released to the public mirrors (msync and mysnc-dvd).

We currently have the top directory (5.1) set to 700 permissions. Thisshould allow you to download as your "rsync" user now, but it will probably not be browseable on your web/ftp server.

We will change the permissions to 775 on the 5.1 directory as we get more than 50% of the external mirrors with the 5.1 tree completed.

We are doing it this way on purpose to allow the syncs to finish BEFORE people start hitting the public mirrors for yum updates.

Also note that we are syncing out with 15 total mirrors, BUT there are more than 300 mirrors that sync from these ... so it might be slow going for the first couple days.

Also, if any of you can spare EXTRA bandwidth on top of your public mirrors, you could take a copy of the .torrent files from the 5.1/isos/ directories and seed the ISOs for bittorrent as well.
