报错:1130-host ... is not allowed to connect to this MySql server

解决方法：

一.改表法

　　可能是你的帐号不允许从远程登陆，只能在localhost。这个时候只要在localhost的那台电脑，登入mysql后，更改 "mysql" 数据库里的 "user" 表里的 "host" 项，从"localhost"改称"%"。

mysql -u root -pvmwaremysql>use mysql;
mysql>update user set host = '%' where user = 'root';
mysql>select host, user from user;

　　操作如下：

mysql> use mysql
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A
Database changed

mysql> select host from user where user = 'root';
+-----------+
| host      |
+-----------+
| localhost |
+-----------+
1 row in set (0.00 sec)

mysql> update user set host='%' where user = 'root';
Query OK, 1 row affected (0.00 sec)
Rows matched: 1  Changed: 1  Warnings: 0

mysql> select host from user where user = 'root';
+------+
| host |
+------+
| %    |
+------+
1 row in set (0.00 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

mysql>

 

二.授权法

　　例如，你想myuser使用mypassword从任何主机连接到mysql服务器的话。

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

FLUSH   PRIVILEGES;

　　如果你想允许用户myuser从ip为192.168.1.3的主机连接到mysql服务器，并使用mypassword作为密码

GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'192.168.1.3' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;

FLUSH   PRIVILEGES;

　　如果你想允许用户myuser从ip为192.168.1.6的主机连接到mysql服务器的dk数据库，并使用mypassword作为密码。

GRANT ALL PRIVILEGES ON dk.* TO 'myuser'@'192.168.1.3' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;

FLUSH   PRIVILEGES;

　　我用的第一个方法,刚开始发现不行,在网上查了一下,少执行一个语句 mysql>FLUSH RIVILEGES 使修改生效.就可以了。

 

三.安装机器上运行授权

　　此方法我没有亲自试过的,在youkuaiyun.com上找的,可以看一下

在安装mysql的机器上运行：

1.d:\mysql\bin\>mysql   -h   localhost   -u   root //这样应该可以进入MySQL服务器

2.mysql>GRANT   ALL   PRIVILEGES   ON   *.*   TO   'root'@'%'   WITH   GRANT   OPTION //赋予任何主机访问数据的权限

3.mysql>FLUSH   PRIVILEGES //修改生效

4.mysql>EXIT //退出MySQL服务器

　　这样就可以在其它任何的主机上以root身份登录啦！
