YUM安装软件报错处理

           rpm -ivh python-iniparse-0.4-9.el7.noarch.rpm

           rpm -ivh python-urlgrabber-3.10-8.el7.noarch.rpm

           rpm -ivh yum-metadata-parser-1.1.4-10.el7.x86_64.rpm

 rpm -ivh yum-plugin-fastestmirror-1.1.31-45.el7.noarch.rpm yum-3.4.3-158.el7.centos.noarch.rpm（注意：这两个包要一起装，不然会出现问题的）

3. 配置yum源
