网易开通了一个开源软件的镜像站点

  网易开通了一个开源软件的镜像站点：http://mirrors.163.com/.其中包括镜像的有:Linux及BSD发行版镜像：FreeBSD、OpenBSD、RedHat、archlinux、centos、debian、fedora、gentoo、trixbox、ubuntu等等。不过里面的版本不是很全，希望以后会不断增加。
这次的源地址会替换原来的cn99.
如果您安装 CentOS 系统的服务器位于电信机房，因为该镜像目前只有一台杭州电信的服务器，网通用户访问可能会比较慢，您可以修改/etc/yum.repos.d/CentOS-Base.repo文件，将它的yum源更改成网易的镜像，代替国外的镜像，以便获取更快的下载速度。
# CentOS-Base.repo  
#  
# This file uses a new mirrorlist system developed by Lance Davis for CentOS.  
# The mirror system uses the connecting IP address of the client and the  
# update status of each mirror to pick mirrors that are updated to and  
# geographically close to the client.  You should use this for CentOS updates  
# unless you are manually picking other mirrors.  
#  
# If the mirrorlist= does not work for you, as a fall back you can try the   
# remarked out baseurl= line instead.  
#
