Linux7.4 yum更新源优先级设置

1.安装 yum-priorities

　　yum install yum-priorities

2.priorities的配置文件是/etc/yum/pluginconf.d/priorities.conf，确认其是否存在。内容为：

[root@chy002 yum.repos.d]# cat !$
cat /etc/yum/pluginconf.d/priorities.conf
[main]
enabled = 1

3.编辑 /etc/yum.repos.d/目录下的*.repo 文件来设置优先级。参数为：

　　priority=N   # N的值为1-99，数字越大,优先级越低

　　推荐的设置为：
　　[base], [addons], [updates], [extras] … priority=1 
　　[centosplus],[contrib] … priority=2
　　Third Party Repos such as rpmforge … priority=N   (where N is > 10 and based on your preference)
