在dell r410上面装的是centos6,64的操作系统，用的163的源，我一直都是用163的源，比较快。但是我发现这个源里面，根本没有libmcrypt libmcrypt-devel这二个包，装php扩展mcrypt时，又要用到这二个包，所以我手动装了libmcrypt包，但是给我的感觉是163源中的包不全。后来有一个朋友告诉我用epel，用了之后感觉很爽。
一，什么是epel
如果既想获得 RHEL 的高质量、高性能、高可靠性，又需要方便易用(关键是免费)的软件包更新功能，那么 Fedora Project 推出的 EPEL(Extra Packages for Enterprise Linux)正好适合你。EPEL(http://fedoraproject.org/wiki/EPEL) 是由 Fedora 社区打造，为 RHEL 及衍生发行版如 CentOS、Scientific Linux 等提供高质量软件包的项目。
二，使用心得
1，不用去换原来yum源，安装后会产生新repo
2，epel会有很多源地址，如果一个下不到，会去另外一个下
http://mirror.xfes.ru/fedora-epel/6/x86_64/ibus-table-chinese-scj-1.3.4-1.el6.noarch.rpm: [Errno 14] PYCURL ERROR 6 - ""
Trying other mirror.
http://mirrors./fedora/epel/6/x86_64/ibus-table-chinese-scj-1.3.4-1.el6.noarch.rpm: [Errno 14] PYCURL ERROR 6 - ""
Trying other mirror.
http://repo.boun.edu.tr/epel/6/x86_64/ibus-table-chinese-scj-1.3.4-1.el6.noarch.rpm: [Errno 14] PYCURL ERROR 6 - ""kjs
。。。。。。
3，更新时如果下载的包不全，就不会进行安装。这样的话，依赖关系可以保重
三，安装epel,centos6选6，5就选5
32位系统选择：
rpm -ivh http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm
rpm -ivh http://dl.fedoraproject.org/pub/epel/5/i386/epel-release-5-4.noarch.rpm
64位系统选择：
rpm -ivh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
rpm -ivh http://dl.fedoraproject.org/pub/epel/5/x86_64/epel-release-5-4.noarch.rpm
rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6
rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-5
如果用比较新的软件，用epel-test.repo这个文件就行了
别忘了安装yum install yum-priorities
[root@localhost yum.repos.d]# ls |grep epel
epel-testing.repo

目前伪极客和另外一位朋友遇到安装错误都是因为的CentOS6.5缺少VestaCP安装所需要的软件依赖包所导致的。具体错误代码为
: Failed dependencies :
epel-release &=6 is needed by remi -release-6.5-1.el6.remi.noarch
: Failed dependencies :epel-release &=6 is needed by remi -release-6.5-1.el6.remi.noarch
听说centos6.5被“优化”的很过分，以上问题便是缺少Extra Packages for Enterprise Linux (EPEL)导致的，可以理解为是企业Linux的额外的软件包,EPEL由一个Fedora特别网络小组共同创建、维护和管理,提供高质量额外的企业版Linux软件包。
我们只要安装EPEL包即可。
$ wget http://mirrors./fedora/epel/6/x86_64/epel-release-6-8.noarch.rpm
$ wget http://mirrors.ustc.edu.cn/fedora/epel/6/x86_64/epel-release-6-8.noarch.rpm
$ sudo rpm -ivh epel-release-6-8.noarch.rpm
$ sudo rpm -ivh epel-release-6-8.noarch.rpm
安装好EPEL 后，用yum 命令来检查是否添加到源列表
# yum repolist
# yum repolist
# yum repolist

EPEL已经在repo 后列出，并且显示提供了上万个软件包，所以EPEL 已经安装到你的CentOS了。
然后重新执行VestaCP的安装即可。

Centos安装EPEL扩展源
Centos官方源很多软件都没有，编译安装又比较麻烦，可以安装EPEL源解决此问题。
EPEL即Extra Packages for Enterprise Linux，也就是为企业级&Linux提供的扩展软件源，适用于 RHEL，CentOS，Scientific Linux系统。

EPEL (Extra Packages for Enterprise Linux) is a volunteer-based community effort from the Fedora project to create a repository of high-quality add-on packages that complement the Fedora-based Red Hat Enterprise Linux (RHEL) and its compatible spinoffs, such as CentOS and Scientific Linux.Tutorial detailsDifficultyEasy (rss)Root privilegesYesRequirementsNoneEstimated completion time10m EPEL provide lots of packages for CentOS / RHEL,
It is not part of RedHat or CentOS but is designed to work with these major distributions. Please note that EPEL only provides free and open source software unencumbered by patents or any legal issues. In short you will not find mp3, dvd and music / media player under EPEL. However, you will find many programs related to networking,
monitoring, sys admin, programming and so on.Packages are supplied in RPM format and in most cases are ready to use. Beware that some packages may break something and you should not blindly install those packages.How Do I Enable EPEL Repo under CentOS or RHEL Servers?You need to type the following command as per your distro version / release.RHEL 5.x / CentOS 5.x UsersType the following command as root user to install repo: # rpm -Uvh http://download.fedoraproject.org/pub/epel/5/i386/epel-release-5-4.noarch.rpmRHEL 6.x / CentOS 6.x UsersType the following command as root user to install repo: # rpm -Uvh http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpmProtect Base PackagesYou need to to protect base and core packages from EPEL and other repositories. Type the following command under RHEL 6/CentOS 6:Note for RHN (Red Hat) users: You need to also enable the 'optional' repository to use EPEL packages as they depend on packages in that repository. This can be done by enabling the RHEL optional subchannel for RHN-Classic. For certificate-based subscriptions see RHEL Deployment Guide# yum install yum-plugin-protectbase.noarch Sample outputs:
Loaded plugins: product-id, rhnplugin, subscription-manager
