解决方法:

  1. 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"%"
mysql>mysql -u root -p;
mysql>use mysql;
mysql>update user set host = '%' where user = 'root';
mysql>select host, user from user;
  1. 授权法。例如,你想root使用mypassword从任何主机连接到mysql服务器的话。

允许root用户在任何地方均可链接:

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

如果你想允许用户root从ip为特定IP(如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 'root'@'192.168.1.3' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;

通过任意一种方式进行修改时,要重启MySQL服务,方能生效
