1.登录mysql(注意:账号密码不包括,-u和-p)

mysql -uroot -proot

2.切换到mysql库:

use mysql;

3.查询root用户的host值:

select user,host from user;

如果host的值是localhost,说明只支持本地连接,不能远程登录
4.更改host的值为%:

update user set host = '%' where user='root';

5.刷新权限:

flush privileges;

 

6.重启MySQL

net stop mysql

net start mysql

7.即可外部连接mysql
