HomeDatabaseMysql TutorialLinux中开启MySQL远程访问功能

(1)确认一下3306是否对外开放,MySQL默认状态下是不开放对外访问功能的。查看的办法如下:1 ~# netstat -an | grep 3306 2 tc

(1)确认一下3306是否对外开放,,MySQL默认状态下是不开放对外访问功能的。查看的办法如下:

1 ~# netstat -an | grep 3306 

2 tcp 0 0 127.0.0.1:3306 0.0.0.0:* LISTEN

从上面可以看出,mysql的3306端口只是监听本地的连接,这样就阻碍了外部IP对该数据库的访问,修改的办法其实很简单,进入到mysql的配置文件所在目录(/etc/mysql/my.cnf)下,找到文件中的如下内容:


1 # Instead of skip-networking the default is now to listen only on 

2 # localhost which is more compatible and is not less secure. 

3 bind-address = 127.0.0.1

给bind-address添加注释,(或者改成你想要使用的客户端主机IP)(这个我没成功)。
这样mysql的远程访问端口就算开启了,下面还有一个更重要的步骤,就是要给远程用户授权。

(2)确认客户端用户是否具有访问权限。
为了让访问mysql的客户端的用户有访问权限,我们可以通过如下方式为用户进行授权:

1 mysql> grant all on *.* to user_name@'%' identified by 'user_password'; 

2 #或者 

3 mysql> grant all privileges on *.* to username@"%" identified by "password";  #(这句准) 

4 #或者 

5 CREATE USER 'test' @' 125.76.229.113' IDENTIFIED BY '26756880'; 

6 CREATE USER 'test'@' 125.76.229.215' IDENTIFIED BY '26756880'; 

7 CREATE USER 'test'@' 60.195.252.106' IDENTIFIED BY '26756880';

上面的命令授予的用户权限可以访问mysql中的任意数据库(database)和表(table)。
完成上面的两个步骤,重启mysql即可在远程登陆mysql服务器了。Mysql的重启命令如下:

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.
