host...is not allowed to connect to this MySql server开放mysql远程连接不使localhost解决方法

 

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:/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!

Adding MySQL users through the PHP web interface can use MySQLi extensions. The steps are as follows: 1. Connect to the MySQL database and use the MySQLi extension. 2. Create a user, use the CREATEUSER statement, and use the PASSWORD() function to encrypt the password. 3. Prevent SQL injection and use the mysqli_real_escape_string() function to process user input. 4. Assign permissions to new users and use the GRANT statement.
