设置MySQL允许外网访问

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;
