Linux上安装EPEL扩展包

EPEL(Extra Packages for Enterprise Linux)是由Fedora Special Interest Group维护的 Enterprise Linux（RHEL、CentOS）中经常用到的包，这个里面包含了很多软件扩展包，比如 FreeTDS、ninja 等软件，这个扩展包非常好，直接从EPEL中安装软件不仅安装方便，还省去了从 GitHub 上下载源码编译的过程。

安装 EPEL扩展包

EPEL 镜像由很多，如下列举了三个镜像源：

1. 阿里云EPEL镜像：https://mirrors.aliyun.com/epel/epel-release-latest-7.noarch.rpm
2. 清华大学开源软件镜像：https://mirrors.tuna.tsinghua.edu.cn/epel/7/x86_64/Packages/e/epel-release-7-14.noarch.rpm
3. Fedora镜像：https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
