rhel 6.5 x86_64 配置centos yum源

1、删除rhel自带的yum源
# rpm -aq | grep yum|xargs rpm -e --nodeps
2、下载新的yum安装包
wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-metadata-parser-1.1.2-16.el6.x86_64.rpm wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-3.2.29-69.el6.centos.noarch.rpm wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-30.el6.noarch.rpm 3、安装yum包，注意的是标红的必须一起装，有依赖关系
rpm -ivh yum-metadata-parser-1.1.2-16.el6.x86_64.rpm yum-3.2.29-69.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-30.el6.noarch.rpm
4、更改成163的yum源
# cd /etc/yum.repos.d/
# wget http://mirrors.163.com/.help/CentOS6-Base-163.repo # ls
CentOS6-Base-163.repo
把文件里面的$releasever全部替换为版本号，即6
# sed -i 's#$releasever#6#g' CentOS6-Base-163.repo
5、清除yum缓存
# yum clean all
# yum makecache #将服务器上的软件包信息缓存到本地,以提高搜索安装软件的速度
