为centos添加第三方源

默认centos自带的源少了很多好软件，所以需要添加第三方源

一、安装CentOS yum源优先级插件yum-priorities

yum install yum-plugin-priorities.noarch

二、设置CentOS默认yum源的优先级为最高

cd  /etc/yum.repos.d/   #进入yum源目录

vi CentOS-Base.repo    #在[base]、[updates]、[extras]组下面添加priority=1，在[centosplus]、[contrib]组下面添加priority=2

################################################################   

[base]

name=CentOS-$releasever - Base

mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os

#baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/

gpgcheck=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6

priority=1

备注：priority的优先级为1到99，设置为1即优先级最高，1-10为系统保留，第三方yum源的优先级从11-99

三、安装epel yum源

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

    rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6

    vi /etc/yum.repos.d/epel.repo   #修改epel yum源优先级，priority=11

###############################################################

    [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
