一、删除原来的yum源
1、检查yum源：
rpm -qa | grep yum
1
2、删除原来的yum源
rpm -qa|grep yum|xargs rpm -e --nodeps
1
3、防止系统自带的插件subscription-manager订阅管理器进行注册
vi /etc/yum/pluginconf.d/subscription-manager.conf
#enabled=1
1
2
二、拷贝这三个安装包
如果没有可以从这个地址下载：https://mirrors.aliyun.com/centos/7/os/x86_64/Packages/
yum-3.4.3-168.el7.centos.noarch.rpm
yum-metadata-parser-1.1.4-10.el7.x86_64.rpm
yum-plugin-fastestmirror-1.1.31-54.el7_8.noarch.rpm
三、安装三个包
1、使用以下命令一次性安装3个包
rpm -ivh yum-*
1
2、检查是否安装成功
rpm -qa |grep yum
1
四、配置repo文件
1、在linux中进入etc文件，备份yum.repos.d文件
cd /etc
mv yum.repos.d yum.repos.d.bak
mkdir yum.repos.d
1
2
3
2、下载repo文件
wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo
1
或者
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
1
3、修改下载好的repo文件
下载好的repo文件应该在etc/yum.repos.d目录下，里面应该也只有一个文件，直接vim 文件名
vim /etc/yum.repos.d/CentOS-Base.repo
1
把repo文件里所有 $releasever全部替换成版本号7
操作如下：
按下i键，然后按:
输入命令：
%s/$releasever/7/g
1
替换完毕后，按Esc，然后 :wq 保存退出vim模式
2）-3）也可以手工放入
# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.
