yum 源设置

有很多 操作系统 开源镜像站点，里面有各种版本的操作系统，当然也有很多源包

网易：         http://mirrors.163.com/

搜狐：         http://mirrors.sohu.com/

中科大：     http://mirrors.ustc.edu.cn/

LUPA：       http://mirror.lupaworld.com/

1.  首先备份/etc/yum.repos.d/CentOS-Base.repo

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

下载对应版本repo文件, 放入/etc/yum.repos.d/(操作前请做好相应备份)

2. 安装epel源

wget http://download.fedoraproject.org/pub/epel/5/i386/epel-release-5-4.noarch.rpm

rpm -ivh epel-release-5-4.noarch.rpm

会在/etc/yum.repos.d/目录下，生成epel.repo  epel-testing.repo 两个源

3. 运行yum makecache生成缓存

下面给出我的网易和epel源，供大家参考：
