服务端配置nginx代理

server{
       listen 16666;
       server_name _;
        add_header Access-Control-Allow-Origin *;
        add_header Access-Control-Allow-Headers X-Requested-With;
        add_header Access-Control-Allow-Methods GET,POST,OPTIONS;

        location / {
            root   html;
            index  index.html index.htm;
        }

        location /centos/ {
            proxy_pass //mirrors.aliyun.com/centos/;
        }

        location /epel/ {
            proxy_pass //mirrors.aliyun.com/epel/;
        }

        location /mariadb/ {
            proxy_pass //mirrors.ustc.edu.cn/mariadb/;
        }

    }

[root@master1 ~]# cd /etc/yum.repos.d/
[root@master1 yum.repos.d]# vim CentOS-Base.repo
