mysql 设置远程访问

如果密码为空首先修改一下密码

UPDATE USER SET PASSWORD=PASSWORD('root') WHERE USER='root';

允许所有IP访问

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'root' WITH GRANT OPTION;

允许某一个IP访问

GRANT ALL PRIVILEGES ON *.* TO 'root'@'192.168.XX.XX' IDENTIFIED BY 'root' WITH GRANT OPTION;

记得刷新下

FLUSH PRIVILEGES;
