1.改表法?？赡苁悄愕膸ぬ柌辉试S從遠程登陸，只能在localhost。這個時候只要在localhost的那臺電腦，登入mysql后，更改 "mysql" 數據庫中 "user" 表里的 "host" 字段，把"localhost"改稱"%"，即可。

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

2.授權法。例如，你想用戶myuser使用密碼mypassword通過ip地址連接到mysql服務器，使用：
GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'%' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;
如果你想允許用戶myuser從ip為192.168.1.3的主機連接到mysql服務器，并使用mypassword作為密碼
GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'192.168.1.3' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;
