首先检查系统是否安装epel-release:

rpm -q epel-release

package epel-release is not installed

2.如果没有安装，则install：

[root@flc ~]# sudo rpm -ivh http://mirrors.ustc.edu.cn/fedora/epel/6/x86_64/epel-release-6-8.noarch.rpm

Notice:

64位：http://mirrors.ustc.edu.cn/fedora/epel/6/x86_64/epel-release-6-8.noarch.rpm

[root@flc ~]# rpm -q epel-release

epel-release-6-8.noarch   

顺便BS下360图书馆,居然不让复制,话说他家的东西也是从别处复制的吧
