解决思路一：

百度到 https://blog.csdn.net/dantadanta/article/details/106964051，给出的解决方法为：

1，登陆root帐号

2，cd /etc/yum.repo.d

3，mv CentOS-Base.repo CentOS-Base.repo.bak
4，wget http://mirrors.aliyun.com/repo/Centos-7.repo
5，mv Centos-7.repo CentOS-Base.repo
6， yum clean all
7， yum makecache
8，yum update

4~5步骤可以wget一步到位的

如果你是6开头的centos版本，那么只要将上面的所有7改为6即可

注意一般会备份一个原有的CentOS-Base.repo，我将其命名为CentOS-Base2.repo

但还是同样的错，发现那个404的地址没有切换成功，所以得证我的配置文件没生效

后来将CentOS-Base2.repo改名为CentOS-Base2.repo.bak后才生效不再报错

 

解决思路二：

直接在Linux环境表 使用python命令安装即可：

[tester@Linux tools]$ pip install requests
