1. 去sohu镜像下载epel-release-6包 并安装。
#wget http://mirrors.sohu.com/fedora-epel/6/x86_64/epel-release-6-8.noarch.rpm
注意：需要在浏览器中进入 http://mirrors.sohu.com/fedora-epel/6/x86_64/ 文件夹，然后查找epel-release-6包，我现在的最新版本是 8 ，所以要根据具体版本下载相应包，而不可复制上面的现在命令。
[root@centos64 fedora-epel]# wget http://mirrors.sohu.com/fedora-epel/6/x86_64/epel-release-6-8.noarch.rpm
