1.删除redhat原有的yum 
rpm -aq|grep yum|xargs rpm -e --nodep

2.安装163的yum包,wget 后面的路径要根据实际情况,有可能版本已经更新，


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-metadata-parser-1.1.2-16.el6.x86_64.rpm

wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-30.el6.noarch.rpm

wget http://mirrors.163.com/centos/6/os/x86_64/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm


3.安装这些yum包

rpm -ivh yum-metadata-parser-1.1.2-16.el6.x86_64.rpm

rpm -ivh python-iniparse-0.3.1-2.1.el6.noarch.rpm

这两个是依赖包，要同时安装

rpm -ivh yum-3.2.29-69.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-30.el6.noarch.rpm

4.备份文件

cd /etc/yum.repos.d

cp CentOS-Base.repo CentOS-Base.repo.bak

cp CentOS6-Base-163.repo CentOS-Base.repo

vim CentOS-Base.repo
