Mysql开启远程访问

Mysql开启远程访问

默认情况下，mysql的用户没有远程访问的权限。

一、改表法

默认mysql不允许从远程登陆，只能在localhost。这个时候只要在localhost的那台电脑，登入mysql后，更改 "mysql" 数据库里的 "user" 表里的 "host" 项，从"localhost"改称"%"

update user set host = '%' where user = 'root';
flush privileges;

二、授权法

赋予任何主机访问数据的权限

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%'WITH GRANT OPTION;
flush privileges;

赋予myuser使用mypassword从任何主机连接到mysql服务器

GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'%' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;
flush privileges;

只允许用户myuser从ip为192.168.1.6的主机连接到mysql服务器，并使用mypassword作为密码

GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'192.168.1.3' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;
flush privileges;
