设置MySQL允许外网访问

Posted 2020-10-06 Life Love Tech

1.修改配置文件
sudo vim /etc/mysql/my.cnf
把bind-address参数的值改成你的内/外网IP或0.0.0.0,或者直接注释掉这行.

2.登录数据库
mysql -u root -p

输入密码
mysql> use mysql;

3.查询host
mysql> select user,host from user;

4.创建host
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;

5.授权用户
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;

 

PS：以上为授权方法，以下为改表方法：

mysql> use mysql;
mysql> update user set host=\'%\' where user=\'root\';
mysql> flush privileges;
