今天在测试docker时，因更换为Mysql8，使用SQL方式实现远程授权，其方式方法同于Mysql，但语句稍有不同，仅供参考。

登录mysql

mysql -u root -p
输入密码: [请依据交互输入你的mysql密码]

切换数据库

use mysql;

选择需要查看的信息

select host, user from user;
+-----------+------------------+
| host      | user             |
+-----------+------------------+
| localhost | mysql.infoschema |
| localhost | mysql.session    |
| localhost | mysql.sys        |
| localhost | root             |
+-----------+------------------+

直接给指定用户授权

update user set host='%' where user='root';
grant all privileges on *.* to 'root'@'%';
flush privileges;
grant all on *.* to 'root'@'%';
flush privileges;

创建新用户并授权

create user 'root'@'%' identified by 'YourPassword';
grant all privileges on *.* to 'root'@'%';
flush privileges;
grant all on *.* to 'root'@'%';
flush privileges;
