CentOS EPEL yum源

用yum安装软件时，经常发现我们的yum源里面没有该软件，比如htop。网上查到的一个方案是需要自己去wget源码，然后configure，make，make install，总体比较麻烦。

其实，CentOS还有一个源叫做 EPEL (Extra Packages for Enterprise Linux)，为“红帽系”的操作系统提供额外的软件包，适用于RHEL、CentOS等，里面有1万多个软件，强烈建议安装。

安装 epel-release

首先我们需要安装一个叫“epel-release”的软件包，这个软件包会自动配置yum的软件仓库。到下面的网址找你对应的CentOS版本和计算机架构：http://download.fedoraproject.org/pub/epel

我的是64位的CentOS7，对应的地址是：https://mirrors.ustc.edu.cn/epel//7/x86_64/Packages/e/epel-release-7-11.noarch.rpm

下载并安装epel-release-7-11.noarch.rpm
