1。改表法。在數據庫所在機器登入mysql後，更改 "mysql" 數據庫裏的 "user" 表裏的 "host" 項，把"localhost"改稱"%"

mysql -u root -p 
mysql>use mysql; 
mysql>select 'host' from user where user='root'; 
mysql>update user set host = '%' where user ='root'; 
mysql>flush privileges; 
mysql>select host,user   from user where user='root';

重起mysql服務便可完成。

2. 受權法。在數據庫所在機器登入mysql後，直接進行受權

grant all privileges on . to 'root'@'%' identified by 'password' with grant option;
