解决方法

改表法

可能是你的帐号不允许从远程登陆,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”%
具体操作为:

连接mysql服务器:mysql -u root -p
看当前所有数据库:show databases;
进入mysql数据库:use mysql;
查看mysql数据库中所有的表:show tables;
查看user表中的数据:select Host, User,Password from user;
修改user表中的Host:update user set host = '%' where user = 'root';
刷新授权列表:flush privileges;

通过以上操作,再重新连接便成功

授权法

例如,你想myuser使用mypassword从任何主机连接到mysql服务器的话。

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

如果你想允许用户myuser从ip为192.168.1.3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;
