远程访问
mysql不允许远程用户访问主机服务器 1130
以下百度查到的，试过可以
说明所连接的用户帐号没有远程连接的权限，只能在本机(localhost)登录。
需更改 mysql 数据库里的 user表里的 host项
把localhost改称%
具体步骤：登陆到mysql
首先 use mysql；
按照别人提供的方式update的时候，出现错误。
mysql> update user set host='%' where user = 'root';
ERROR 1062 (23000): Duplicate entry '%-root' for key 'PRIMARY'
然后查看了下数据库的host信息如下：
mysql> select host from user where user = 'root';
+-----------------------+
| host |
+-----------------------+
| % |
| 127.0.0.1 |
| localhost.localdomain |
+-----------------------+
3 rows in set (0.00 sec)
host已经有了%这个值，所以直接运行命令：
mysql>flush privileges;
再用mysql administrator连接...成功！！！
（ps:以后要是忘记了可以随时来看
