yum - epel源

背景

EPEL (Extra Packages for Enterprise Linux) 是Fedora小組維護的一個軟件倉庫項目，提供了官方源不支持的或者官方更新緩慢的包，不少開源軟件須要用epel源進行安裝，do it.

安裝

1.查看已有源，sudo yum repolist

Loading mirror speeds from cached hostfile
 * epel: mirror.sjc02.svwh.net

2.卸載。若是已有epel 源但不可用而且問題很差定位，則執行yum -y remove epel-release卸載舊版

3.安裝epel源

; centos7就選`latest-7`,同理6選latest-6
wget https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

4.安裝rpm

sudo yum install epel-release-latest-7.noarch.rpm

5.檢查版本:

rpm -q epel-release

其餘

1. yum repo的路徑爲/etc/yum.repos.d
2. epel.repo的文件內容以下,若是須要關閉某個源，則將配置文件中的enabled置爲0
