rpm -ivh python-* #rpm-python-*
如果中间过程出现了类似下面的代码，这是包与包之间的依赖关系，只需要卸载已经安装的包（rpm -e 包名（没有.rpm后缀）），然后先安装依赖包
如：
rpm -e yum-metadata-parser-1.1.2-16.el6.x86_64
rpm -ivh /yum-metadata-parser-1.1.2-16.el6.x86_64.rpm
- 安装yum
mkdir /usr/local/src/yum
wget http://mirrors.163.com/centos/6.9/os/x86_64/Packages/yum-3.2.29-81.el6.centos.noarch.rpm
wget http://mirrors.163.com/centos/6.9/os/x86_64/Packages/yum-metadata-parser-1.1.2-16.el6.x86_64.rpm
wget http://mirrors.163.com/centos/6.9/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-40.el6.noarch.rpm
rpm -ivh yum-*
- 完成
yum
