How Do I Verify EPEL Repo?（如何使用epel源安裝軟件）
You need to run the following command to verify that the EPEL repository is enabled. Once you ran the command you will see epel repository.（確認(rèn)安裝是否成功執(zhí)行下邊命令，會(huì)出現(xiàn)epel repository庫）
# yum repolist ?#查看活躍的庫
Sample Output

How Do I Use EPEL Repo?（如何使用epel）
You need to use YUM command for searching and installing packages. For example we search for Zabbix package using epel repo, lets see it is available or not under epel.
# yum --enable repo=epel info zabbix （查看是否有zabbix軟件）
Sample Output
Available Packages Name? ? ? : zabbix Arch? ? ? : i386 Version? ? : 1.4.7 Release? ? : 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.
Let’s install Zabbix package using epel repo option–enable repo=epel switch.
# yum --enable repo=epel install zabbix （安裝zabbix）
Note: The epel configuration file is located under /etc/yum.repos.d/epel.repo.（配置文件在/etc/yum.repos.d/epel.repo這個(gè)路徑下）
This way you can install as many as high standard open source packages using EPEL repo.
