如果既想獲得?RHEL?的高質量、高性能、高可靠性，又需要方便易用(關鍵是免費)的軟件包更新功能，那么?Fedora?Project?推出的?EPEL(Extra?Packages?for?Enterprise?Linux)正好適合你。EPEL(http://fedoraproject.org/wiki/EPEL)?是由?Fedora?社區打造，為?RHEL?及衍生發行版如?CentOS、Scientific?Linux?等提供高質量軟件包的項目。裝上了?EPEL，就像在?Fedora?上一樣，可以通過?yum?install?package-name，隨意安裝軟件。??

1、RHEL/CentOS/SL?Linux?6.x?下安裝?EPEL6?yum源：

32位系統選擇：

rpm?-ivh?http://download.fedora.redhat.com/pub/epel/6/i386/epel-release-6-5.noarch.rpm

或者?rpm?-ivh?ftp://ftp.muug.mb.ca/mirror/fedora/epel/6/i386/epel-release-6-5.noarch.rpm

64位系統選擇：

rpm?-ivh?http://download.fedora.redhat.com/pub/epel/6/x86_64/epel-release-6-5.noarch.rpm

?rpm?-ivh?ftp://ftp.muug.mb.ca/mirror/fedora/epel/6/x86_64/epel-release-6-5.noarch.rpm

rpm?-Uvh?http://dl.iuscommunity.org/pub/ius/stable/Redhat/6/x86_64/epel-release-6-5.noarch.rpm

導入key：
rpm?--import?/etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6

2、默認會在/etc/yum.repos.d/下創建epel.repo和epel-testing.repo兩個配置文件，epel.repo的內容如下：

[epel]
name=Extra?Packages?for?Enterprise?Linux?6?–?$basearch
#baseurl=http://download.fedoraproject.org/pub/epel/6/$basearch
mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-6&arch=$basearch
failovermethod=priority
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6

[epel-debuginfo]
name=Extra?Packages?for?Enterprise?Linux?6?–?$basearch?–?Debug
#baseurl=http://download.fedoraproject.org/pub/epel/6/$basearch/debug
mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-debug-6&arch=$basearch
failovermethod=priority
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6
gpgcheck=1

[epel-source]
name=Extra?Packages?for?Enterprise?Linux?6?–?$basearch?–?Source
#baseurl=http://download.fedoraproject.org/pub/epel/6/SRPMS
mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-source-6&arch=$basearch
failovermethod=priority
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6
gpgcheck=1

如果想使用比較新的軟件，可以啟用[epel-testing]源，把里面的enabled=0改成enabled=1就可以。

3、yum安裝heartbeat測試看看：

yum?install?heartbeat
