在本机上可以登录数据库，但是用Navicat一直连不上MySQL。

用下文方法中的“授权法”后，Navicat就连上了。

报错:1130-host ... is not allowed to connect to this MySql server 开放mysql远程连接不使用localhost

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

解决方法：

1。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;

2. 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192.168.1.6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

另外一种方法,不过我没有亲自试过的,在csdn.net上找的,可以看一下.

在安装mysql的机器上运行：

1、d:mysqlin>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！
