EPEL的全称叫 Extra Packages for Enterprise Linux 。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。装上了 EPEL之后,就相当于添加了一个第三方源。
如果你知道rpmfusion.org的话,拿 rpmfusion 做比较还是很恰当的,rpmfusion 主要为桌面发行版提供大量rpm包,而EPEL则为服务器版本提供大量的rpm包,而且大多数rpm包在官方 repository 中是找不到的。
另外一个特点是绝大多数rpm包要比官方repository 的rpm包版本要来得新,比如我前些日子在CentOS上安装的php,RHEL为了稳定性还在延用5.1.6版,我记得这是去年上半年的版本,而php 的最新版本已经到5.3.2,如果在php5.1.6的基础上安装phpmyadmin,则会提示php版本过低,这时候,EPEL中提供的较新php rpm就能很方便的派上用场了。
首先,你需要使用wget下载文件,使用RPM安装EPEL库 (请确保您必须是root用户)
wget http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpmrpm -ivh epel-release-6-8.noarch.rpm
wget http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpmrpm -ivh epel-release-6-8.noarch.rpm
wget http://download.fedoraproject.org/pub/epel/5/i386/epel-release-5-4.noarch.rpmrpm -ivh epel-release-5-4.noarch.rpm
wget http://download.fedoraproject.org/pub/epel/5/x86_64/epel-release-5-4.noarch.rpmrpm -ivh epel-release-5-4.noarch.rpm
您需要运行下面的命令来验证EPEL存储库启用。一旦你运行了该命令,你会看到EPEL存储库。
$yum repolist Loaded plugins: downloadonly, fastestmirror, priorities Loading mirror speeds from cached hostfile * base: centos.aol.in * epel: ftp.cuhk.edu.hk * extras: centos.aol.in * rpmforge: be.mirror.eurid.eu * updates: centos.aol.inReducing CentOS-5 Testing to included packages only Finished1469 packages excluded due to repository priority protections repo id repo name status base CentOS-5 - Base 2,718+7epel Extra Packages for Enterprise Linux 5 - i386 4,320+1,408extras CentOS-5 - Extras 229+53rpmforge Red Hat Enterprise 5 - RPMforge.net - dag 11,251repolist: 19,075
您需要使用yum命令搜索并安装软件包。例如,我们需要安装的zabbix,让我们看看它是不是属于EPEL。
$yum --enablerepo=epel info zabbixAvailable Packages Name : zabbix Arch : i386 Version : 1.4.7Release : 1.el5 Size : 1.7 M Repo : epel Summary : Open-source monitoring solution for your IT infrastructure URL : http://www.zabbix.com/ License : GPL Description: ZABBIX is software that monitors numerous parameters of a network.
通过epel repo安装Zabbix包时需要使用参数�Cenablerepo=epel
yum --enablerepo=epel install zabbix
Note: The epel configuration file is located under /etc/yum.repos.d/epel.repo.
