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!
Iii. install and use epel yum source in CentOS 5.X
1. view the operating system version
[Root @ localhost ~] # Lsb_release-
LSB Version: core-3.1-amd64: core-3.1-ia32: core-3.1-noarch: graphics-3.1-amd64: graphics-3.1-ia32: graphics-3.1-noarch:

2. Download the corresponding EPEL Source
(1). 32-bit System
[Root @ localhost src] # wget http://download.fedoraproject.org/pub/epel/5/i386/epel-release-5-4.noarch.rpm

(2). 64-bit System
1 [root @ localhost src] # wget http://download.fedoraproject.org/pub/epel/5/x86_64/epel-release-5-4.noarch.rpm

3. Install the EPEL source (Note: I am using a 64-bit System)
[Root @ localhost src] # rpm-ivh epel-release-5-4.noarch.rpm
Warning: epel-release-5-4.noarch.rpm: Header V3 DSA signature: NOKEY, key ID 217521f6

4. Import the key file
1 [root @ localhost src] # rpm -- import/etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5

5. view the installed EPEL Source
[Root @ localhost src] # cd/etc/yum. repos. d/
[Root @ localhost yum. repos. d] # ll
Total 24
-Rw-r -- 1 root 2245 2010-04-26 CentOS-Base.repo
-Rw-r -- 1 root 626 2010-04-26 CentOS-Media.repo
-Rw-r -- 1 root 954 2010-08-12 epel. repo # official version, all software is stable and reliable
-Rw-r -- 1 root 1054 2010-08-12 epel-testing.repo # latest test Source

Note: by default, only the official version is valid. If you want to try the test version, you need to modify/etc/yum. repos. d/epel-testing.repo, change enabled = 0 to enabled = 1.
6. Test
[Root @ localhost yum. repos. d] # yum clean all
[Root @ localhost yum. repos. d] # yum list
