解决方法如下:

1、修改表,登录mysql数据库,切换到mysql数据库,使用sql语句查看
"select host,user from user ;"
\mysql -u root -pvmwaremysql>use
mysql;

\mysql>update user set host = '%' where user
='root';
\mysql>select host, user from
user;
\mysql>flush privileges;

注意:最后一句很重要,目的是使修改生效.如果没有写,则还是不能进行远程连接.

2、授权用户,你想root使用密码从任何主机连接到mysql服务器
\GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'admin123'
WITH GRANT OPTION;flush privileges;

如果你想允许用户root从ip为192.168.12.16的主机连接到mysql服务器
\GRANT ALL PRIVILEGES ON *.* TO
'root'@'192.168.1.16'
IDENTIFIED BY '123456' WITH GRANT OPTION;
