1.卸载redhat原有的yum
rpm -qa | grep yum | xargs rpm -e --nodeps
2.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/yum-metadata-parser-1.1.2-16.el6.x86_64.rpm wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-3.2.29-73.el6.centos.noarch.rpm wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-37.el6.noarch.rpm wget http://mirrors.163.com/centos/6/os/x86_64/Packages/python-urlgrabber-3.9.1-11.el6.noarch.rpm
3.安装下载下来的包，注意下边的顺序
要是有安不上的话，把之前安装的都卸载了，重新安装下边的顺序安装即可
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
注意下面这条，两个软件要同时安装，因为他两互相依赖
rpm -ivh yum-3.2.29-73.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-37.el6.noarch.rpm
备份之前的repo文件
mkdir /tmp/bak
mv /etc/yum.repos.d/* /tmp/bak/
从163下载centos6的repo文件
wget http://mirrors.163.com/.help/CentOS6-Base-163.repo -P /etc/yum.repos.d/
编辑文件，把文件里的$releasever全部替换为版本号
vim /etc/yum.repos.d/CentOS6-Base-163.repo :0,$s/\$releasever/6/g :wq
=================
以下命令含义一次对应：
清理yum缓存
更新yum缓存
安装yum企业源
yum clean all
yum makecache
yum -y install epel-release
切记 不要执行 yum update
