rhel6.5：配置centos源

1、下载yum包
    wget http://mirrors.163.com/centos/6/os/x86_64/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm 
    wget http://mirrors.163.com/centos/6/os/x86_64/Packages/python-urlgrabber-3.9.1-11.el6.noarch.rpm 
    wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-3.2.29-81.el6.centos.noarch.rpm 
    wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-41.el6.noarch.rpm
    wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-metadata-parser-1.1.2-16.el6.x86_64.rpm

2、卸载rhel的yum包
    rpm -qa | grep yum | xargs rpm -e --nodeps
    rpm -qa |grep python-urlgrabber|xargs rpm -e --nodeps
    rpm -qa |grep python-iniparse|xargs rpm -e --nodeps

3、安装centos的yum包
    rpm -ivh python-iniparse-0.3.1-2.1.el6.noarch.rpm
    rpm -ivh python-urlgrabber-3.9.1-11.el6.noarch.rpm
    rpm -ivh yum-metadata-parser-1.1.2-16.el6.x86_64.rpm
    rpm -ivh yum-3.2.29-81.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-41.el6.noarch.rpm

4、下载centos的yum源
    cd /etc/yum.repos.d/
    wget http://mirrors.163.com/.help/CentOS6-Base-163.repo
    sed -i "s;\$releasever;6;g" CentOS6-Base-163.repo
    mv rhel-source.repo rhel-source.repo.bak

5、清除缓存
    yum clean all
    yum repolist
