redhat 5.5和6.5配置網絡yum源

如下爲配置文件/etc/yum.repos.d/rhel-media.repo

更新yum源：

yum clean all

yum makecache

若makecache報錯，導入新的GPG-KEY再執行一次便可搞定

rpm --import http://centos.ustc.edu.cn/centos/RPM-GPG-KEY-CentOS-5

redhat 6.5 配置網絡yum源
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo
sed -i 's/$releasever/6/g' /etc/yum.repos.d/CentOS-Base.repo
yum clean all
yum list
