大家好，又见面了，我是你们的朋友全栈君。

一：删除原有的yum

1.查看已经安装的yum

[root@Server-i-09nwynqbbd ~]# rpm -qa |grep yum
yum-3.4.3-161.el7.centos.noarch
yum-utils-1.1.31-54.el7_8.noarch
yum-plugin-fastestmirror-1.1.31-50.el7.noarch
yum-metadata-parser-1.1.4-10.el7.x86_64

2.删除yum包

[root@Server-i-09nwynqbbd ~]# rpm -qa|grep yum|xargs rpm -e --nodeps

3.查看是否删除完毕（未找到yum包则删除完成）

[root@Server-i-09nwynqbbd ~]# rpm -qa |grep yum
[root@Server-i-09nwynqbbd ~]#

二：查看Liunx系统版本

[root@Server-i-09nwynqbbd ~]# uname -an
Linux Server-i-09nwynqbbd 3.10.0-957.el7.x86_64 #1 SMP Thu Nov 8 23:39:32 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
[root@Server-i-09nwynqbbd ~]# cat /etc/redhat-release 
CentOS Linux release 7.6.1810 (Core)

三：下载yum有关的RPM包

[root@Server-i-09nwynqbbd ~]# wget http://mirrors.163.com/centos/7/os/x86_64/Packages/python-iniparse-0.4-9.el7.noarch.rpm
[root@Server-i-09nwynqbbd ~]# wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-3.4.3-168.el7.centos.noarch.rpm
[root@Server-i-09nwynqbbd ~]# wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-utils-1.1.31-54.el7_8.noarch.rpm
[root@Server-i-09nwynqbbd ~]# wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.31-54.el7_8.noarch.rpm
[root@Server-i-09nwynqbbd ~]# wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-metadata-parser-1.1.4-10.el7.x86_64.rpm

四：安装下载好的yum有关的RPM包

[root@Server-i-09nwynqbbd ~]# rpm -ivh python-iniparse-0.4-9.el7.noarch.rpm --force --nodeps
[root@Server-i-09nwynqbbd ~]# rpm -ivh yum-* --force --nodeps
[root@Server-i-09nwynqbbd ~]# rpm -qa |grep yum
yum-3.4.3-168.el7.centos.noarch
yum-plugin-fastestmirror-1.1.31-54.el7_8.noarch
yum-utils-1.1.31-54.el7_8.noarch
yum-metadata-parser-1.1.4-10.el7.x86_64

五：查看是否安装完成

[root@Server-i-09nwynqbbd ~]# yum makecache
