内容：
yum虽然很好用，但却有一个小问题，那就是更新速度。对于国内用户，尤其是你的网速还不够快的时候，使用yum意味着漫长的等待。我搜集了几个速度不错的国内源，大家可以自己选择、测试、修改。需要修改的文件是/etc/yum.repos.d/CentOS-Base.repo，记得备份！

首先，备份原yum源
cd /etc/yum.repos.d/
cp CentOS-Base.repo CentOS-Base.repo.bak
然后在下面的源中选择一个来用
vi CentOS-Base.repo
最后更新缓存
yum makecache

以下为收集到的源
1.默认的CentOS-Base.repo文件:

CentOS-Base.repo
# 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. � 
# � 
# �
