下载新的yum包，使用centos6.5的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-3.2.29-69.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

版本可能变化 http://mirrors.163.com/centos/6/os/x86_64/Packages/  查找对应版本

安装下载的centos的yum包

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

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

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

最后两个需要一起安装，否则会出现依赖性错误。

cd /etc/yum.repos.d

wget http://mirrors.163.com/.help/CentOS6-Base-163.repo

vi CentOS6-Base-163.repo

将其中的$releasever更改为centos的版本号
