python误删导致yum不可用,修复yum no module named yum

注: 必须先卸载之前的yum跟python

删除现有的python

rpm -qa|grep python|xargs rpm -ev --allmatches --nodeps #强制删除已安装的python以及关联
whereis python |xargs rm -frv -rf #删除所有残余的文件
whereis python  #验证是否删除成功

删除现有的yum

rpm -qa|grep yum|xargs rpm -ev --allmatches --nodeps #删除yum以及关联

whereis yum |xargs rm -frv -rfm --nodeps #删除文件
