centos7 的yum各种报错 重装yum

有为权限不够。。所以下面的第一部分没删除。。。没权限 从下载依赖包开始。没问题。

cd /到根目录

然后依次

sudo wget https://mirrors.aliyun.com/centos/7/os/x86_64/Packages/python-libs-2.7.5-89.el7.x86_64.rpm
sudo wget https://mirrors.aliyun.com/centos/7/os/x86_64/Packages/python-2.7.5-89.el7.x86_64.rpm

sudo rpm -Uvh yum-metadata-parser-1.1.4-10.el7.x86_64.rpm --nodeps

可以了。yum version / yum update 试试。
（好像有点镜像问题） 下次完善

记得此时python -V是2.7.5的 如果要换成python3 记得软连接。
