设置mysql服务允许外网访问,修改mysql的配置文件,有的是my.ini,有的是my.cnf【linux】.

1:设置mysql的配置文件
     /etc/mysql/my.cnf
     找到 bind-address  =127.0.0.1  将其注释掉;//作用是使得不再只允许本地访问;
 
  重启mysql:/etc/init.d/mysql restart;
 

2:登录mysql数据库:mysql -u root -p
  mysql> use mysql;
 
  查询host值:
mysql> select user,host from user;
 
如果没有"%"这个host值,就执行下面这两句:
mysql> update user set host='%' where user='root';
mysql> flush privileges;
或者也可以执行:
mysql>grand all privileges on  *.*  to root@'%'  identifies  by ' xxxx';
其中 第一个*表示数据库名;第二个*表示该数据库的表名;如果像上面那样 *.*的话表示所有到数据库下到所有表都允许访问;
‘%':表示允许访问到mysql的ip地址;当然你也可以配置为具体到ip名称;%表示所有ip均可以访问;
 后面到‘xxxx'为root 用户的password;
 

举例:

任意主机以用户root和密码mypwd连接到mysql服务器
mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'mypwd' WITH GRANT OPTION;
mysql> flush privileges;

IP为192.168.1.102的主机以用户myuser和密码mypwd连接到mysql服务器
mysql> GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'192.168.1.102' IDENTIFIED BY 'mypwd' WITH GRANT OPTION;
mysql> flush privileges;
