Linux拥有众多的发行版，每个发行版都有提供镜像，但是，在国内这些镜像的下载速度参差不齐，
偶尔会有更新失败的情况。

网上众多推荐的镜像源为163的镜像，笔者通过一段时间的试用，发现某些小众带宽访问163镜像还
是存在一定的问题，所以，决定替换为aliyun的镜像。

下面以修改 CentOS 默认安装源为 阿里云(http://mirrors.aliyun.com/repo/)为例进行说明：

1、备份

cp /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

2、配置软件源

下载新的CentOS-Base.repo 到/etc/yum.repos.d/

CentOS 5

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-5.repo
# CentOS-Base.repo

#

# 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.
