**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csdn.net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
