安装rpm包
1.首先安装python包
rpm -ivh python-urlgrabber-3.9.1-11.el6.noarch.rpm
如果安装出现报错如下：
rpm -ivh python-urlgrabber-3.9.1-11.el6.noarch.rpm
warning: python-urlgrabber-3.9.1-11.el6.noarch.rpm: Header V3 RSA/SHA1 Signature, key ID c105b9de: NOKEY

查看系统中是否安装其他版本的python-urlgrabber包，与下载的rpm包冲突
如果有卸载系统中存在的python-urlgrabber包，重新进行安装
2.安装yum-metadata-parser-1.1.2-16.el6.x86_64.rpm
rpm -ivh yum-metadata-parser-1.1.2-16.el6.x86_64.rpm
3.剩下的两个包一起安装，否则单独安装yum-plugin-fastestmirror包会报错如下：
rpm -ivh --force yum-plugin-fastestmirror-1.1.30-41.el6.noarch.rpm
warning: yum-plugin-fastestmirror-1.1.30-41.el6.noarch.rpm: Header V3 RSA/SHA1 Signature, key ID c105b9de: NOKEY
error: Failed dependencies:
yum >= 3.0 is needed by yum-plugin-fastestmirror-1.1.30-41.el6.noarch
正确安装命令：
rpm -ivh yum-3.2.29-81.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-41.el6.noarch.rpm
至此安装完成
如果yum命令还报错系统未注册
卸载subscription-manager
rpm -qa | grep subscription-manager*
卸载 rpm -e subscription-manager*
yum clean all
yum makecache
yum update
至此yum就可以使用了
