第一次使用IP登录MySQL时会出现的问题

问题过程：

:~$mysql -h xxx.xxx.xxx.xxx -u root -p

Enter password:

ERROE 1045 (28000): Access denied for user ‘root’@’xxx.xxx.xxx.xxx’ (using password: YES)

原因：

没有对其进行授权

解决方法：

1.用localhost登录

:~$mysql -u root -p

Enter password:

2.授权

mysql> grant all privileges on.to root@’%’ identified by ‘123’;

Query OK, 0 rows affected (0.34 sec)

3.退出

mysql> quit

Bye

4.用IP登录

:~$ mysql -h xxx.xxx.xxx.xxx -u root -p

Enter password:
