    问题解决。

    补充

    如果你想允许用户root从ip为192.168.0.8的主机连接到MySql服务器,并使用123456作为密码,可以执行下面的SQL语句:

    GRANT ALL PRIVILEGES ON *.* TO 'root'@'192.168.0.8' IDENTIFIED BY '123456' WITH GRANT OPTION;
    #执行下面的语句,使上面的改动生效
    FLUSH PRIVILEGES;

    如果你想允许用户root从ip为192.168.0.8的主机连接到MySql服务器的testdb数据库,并使用123456作为密码

    GRANT ALL PRIVILEGES ON testdb.* TO 'root'@'192.168.0.8' IDENTIFIED BY '123456' WITH GRANT OPTION;
    #执行下面的语句,使上面的改动生效
    FLUSH PRIVILEGES;
