[数据库]Mysql设置允许外网访问


1、打开mysql.exe(MySQL Command Line Client),输入密码

2、输入:use mysql;

3、查询host输入: select user,host from user;

4、创建host(如果有"%"这个host值,则跳过这一步)

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

(1)任意主机以用户root和密码pwd连接到mysql服务器

mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'pwd' WITH GRANT OPTION;
mysql> flush privileges;

(2)指定IP为(如192.168.1.100)的主机以用户tuser和密码tpwd连接到mysql服务器

mysql> GRANT ALL PRIVILEGES ON *.* TO 'tuser'@'192.168.1.100' IDENTIFIED BY 'tpwd' WITH GRANT OPTION; 
mysql> flush privileges;
