在CentOS上安装EPEL

请注意EPEL 的安装包是独立编译的，所以它可以安装在32位和64位系统中。

1. 下载rmp包：wget http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm

2. 安装rpm包：rpm -ivh epel-release-6-8.noarch.rpm

3. 检查epel源：yum repolist  如出现如下类似提示则表示成功了；

Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
 * base: mirrors.vonline.vn
 * epel: buaya.klas.or.id
 * extras: centos-hn.viettelidc.com.vn
 * updates: mirrors.fibo.vn

4. 安装epel的时候，执行yum repolist 可能会报错：Error: Cannot retrieve metalink for repository: epel. Please verify its path and try again

解决办法：处理很简单，修改文件“/etc/yum.repos.d/epel.repo”， 将baseurl的注释取消， mirrorlist注释掉。即可。
