MySQL默认是没有开启远程控制的,必须添加远程访问的用户,如果是安装版的话,从MySQL提供的控制台进入。用root用户登陆,然后:

用root用户登陆,然后:

grant all privileges on *.* to 创建的用户名 @"%" identified by "密码";

flush privileges; * 刷新刚才的内容*

格式:grant 权限 on 数据库名.表名 to 用户@登录主机 identified by "用户密码";

@ 后面是访问mysql的客户端IP地址(或是 主机名) % 代表任意的客户端,如果填写 localhost 为本地访问(那此用户就不能远程访问该mysql数据库了)。

同时也可以为现有的用户设置是否具有远程访问权限。如下:

use mysql;

update db set host = '%' where user = '用户名'; (如果写成 host=localhost 那此用户就不具有远程访问权限)

FLUSH PRIVILEGES;

查看结果,执行:

use mysql;

select host,user,password from user;

+--------------+--------+---------------+

| Host | User | Password |

+--------------+--------+-----------------+

| localhost | | | U 8RZq

| % | John | 123456 |

| localhost | root |

+--------------+------ --+---------------+
