Yum 安装 epel-release

EPEL（Extra Packages for Enterprise Linux）是基于 Fedora 的一个项目，为“红帽系”的操作系统提供额外的软件包，适用于 RHEL、CentOS 和 Scientific Linux.
在 CentOS 下使用 yum 在安装包的时后往往会发生找不到 rpm 的情况，官方的 rpm repository 提供的 rpm 包也不够丰富，很多时候需要自己编译很痛苦，而 EPEL 恰恰可以解决这两方面的问题。
EPEL 的全称叫 Extra Packages for Enterprise Linux 。
EPEL是由 Fedora 社区打造，为 RHEL 及衍生发行版如 CentOS、Scientific Linux 等提供高质量软件包的项目。
装上了 EPEL之后，就相当于添加了一个第三方源。
