CentOS7 installs third-party yum source EPEL

I. Introduction

EPEL is short for Enterprise Linux Add-on Package, a high-quality add-on package project for Red Hat Enterprise Linux(RHEL) and its derivative distributions (e.g. CentOS, Scientific Linux, Oracle Enterprise Linux) created, maintained, and managed by Fedora's Special Interest Group.

EPEL packages generally do not conflict with packages in the official Enterprise Linux source or replace files with each other. The EPEL project is basically the same as Fedora, including a complete build system, upgrade manager, image manager, and so on.

RPM installation errors:
