不通过ssh通道，mysql 授予远程连接直接访问

语句

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

后来revoke 一下，错误。

重新grant 出现错误。

mysql> GRANT ALL PRIVILEGES ON *.* TO root@'%' IDENTIFIED BY '!DSJdg!' WITH GRANT OPTION;
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

----------------------

解决方案：

删除一些

delete from user where user="root" and host="%";

重新赋予权限grant select, insert, update, delete, create,drop on *.* to root@'%' identified by '!DSJdg!';
