误删 yum 和 python (wget能用)
问：看CSDN垃圾帖 手快把 yum 和 python 删掉了
恢复 yum 和 python
- 查看系统版本
cat /etc/redhat-release
-
去网易镜像找包 地址
http://mirrors.163.com/centos/-
别听垃圾网站去
http://vault.centos.org/找，找得到但是wget不到(因为http不安全的问题),又让你yum另外的插件，我tmyum都没了，我装个锤子，坑！！！ -
按照你的系统层级找，我的是
7.8.2003里面没有，就去7里面找, 坑，不要听那些改系统版本号的，版本号改了里面没有这些文件，有的文件名版本号对对不上，只能一个一个包找，当然如果同是centos7版本我的文件你可以用

3. wget包
```
//wget包 最好新建一个目录保存 方便管理（后面rpm安装 和 删除）
wget http://mirrors.163.com/centos/7/os/x86_64/Packages/lvm2-python-libs-2.02.187-6.el7.x86_64.rpm

3.安装依赖
//方式一：建议 （避免依赖关系错误）
rpm -Uvh --replacepkgs python*.rpm --nodeps --force
rpm -Uvh --replacepkgs rpm-python*.rpm yum*.rpm --nodeps --force --nodeps --force
//方式二：不建议 （我的会有依赖错误，但是网上的抄袭怪都是这个安装而且安装好了，我也不明白）
rpm -Uvh --replacepkgs lvm2-python-libs*.rpm
rpm -Uvh --replacepkgs libxml2-python*.rpm
rpm -Uvh --replacepkgs python*.rpm
rpm -Uvh --replacepkgs rpm-python*.rpm yum*.rpm
//方式三：不建议 （分开安有大量依赖错误）
rpm -ivh libxml2-python-2.9.1-6.el7.5.x86_64.rpm
rpm -ivh python-libs-2.7.5-89.el7.x86_64.rpm
rpm -ivh python-ipaddress-1.0.16-2.el7.noarch.rpm
rpm -ivh python-backports-1.0-8.el7.x86_64.rpm
rpm -ivh python-backports-ssl_match_hostname-3.5.0.1-1.el7.noarch.rpm
rpm -ivh python-2.7.5-89.el7.x86_64.rpm
rpm -ivh python-iniparse-0.4-9.el7.noarch.rpm
rpm -ivh python-pycurl-7.19.0-19.el7.x86_64.rpm
rpm -ivh python-urlgrabber-3.10-10.el7.noarch.rpm
rpm -ivh python-setuptools-0.9.8-7.el7.noarch.rpm
rpm -ivh python-kitchen-1.1.1-5.el7.noarch.rpm
rpm -ivh python-chardet-2.2.1-3.el7.noarch.rpm
rpm -ivh rpm-python-4.11.3-45.el7.x86_64.rpm
rpm -ivh yum-utils-1.1.31-54.el7_8.noarch.rpm
rpm -ivh yum-3.4.3-168.el7.centos.noarch.rpm
rpm -ivh yum-metadata-parser-1.1.4-10.el7.x86_64.rpm
rpm -ivh yum-plugin-aliases-1.1.31-54.el7_8.noarch.rpm
rpm -ivh yum-plugin-protectbase-1.1.31-54.el7_8.noarch.rpm
rpm -ivh yum-plugin-fastestmirror-1.1.31-54.el7_8.noarch.rpm
注： 使用方式一安装完后可以使用方式三再安装一遍，会发现没有依赖错误了，说明安好了
