   打开文件注释掉bind-address=127.0.0.1
   

2. 重启MySQL服务
   $ sudo /etc/init.d/mysql restart
   或 $ sudo systemctl restart mysql.service

3. 连接MySQL

4. 创建远程连接账户并授权
   mysql> CREATE USER 'root'@'%' IDENTIFIED BY '123456';
mysql> grant all privileges on *.* to 'root'@'%';

5. 如果远程连接时报错plugin caching_sha2_password could not be loaded，执行
   mysql> alter user 'root'@'%' identified with mysql_native_password by '123456';
