Configure epel in centos 6

1. What is epel?
Epel, or extra packages for Enterprise Linux (http://Fedoraproject.org/wiki/EPEL), is a program built by the fedora community to provide high-quality software packages for RHEL and its derivative releases such as centos and scientific Linux. You can obtain RHEL's high-quality, high-performance, high-reliability, free, easy-to-use software packages.
Ii. Comparison with 163 Yum Source
Today, centos6.4 x86_64 operating system is installed on Dell r610. After installing the system, I used 163 Yum source to install the software. I always used 163 Yum source, because it is a domestic Yum source, it is faster. However, I found that there are no libmcrypt or libmcrypt-devel RPM packages in this source. These two packages will be used when PHP extension mcrypt is installed, so I manually installed the two libmcrypt packages and found that the packages in the 163 source are incomplete. Later, I installed heartbeat and found no. So I decided to change the source. Then I went to the Internet to search for it and found the epel source. After using it, I felt great. Now, let's summarize and share with you!
