解決方法：
1.改表法。可能是你的帳號不允許從遠程登陸，只能在localhost。這個時候只要在localhost的那臺電腦，登入mysql後，更改 “mysql” 數據庫裏的 “user” 表裏的 “host” 項，從”localhost”改稱”%”
mysql -u root -pvmware
mysql>use mysql;
mysql>update user set host = ‘%’ where user = ‘root’;
mysql>select host, user from user;
2.授權法。例如，你想myuser使用mypassword從任何主機連接到mysql服務器的話。
GRANT ALL PRIVILEGES ON . TO ‘myuser’@’%’ IDENTIFIED BY ‘mypassword’
WITH GRANT OPTION;
如果你想允許用戶myuser從ip爲192.168.1.3的主機連接到mysql服務器，並使用mypassword作爲密碼 GRANT
ALL PRIVILEGES ON . TO ‘root’@’192.168.1.3’ IDENTIFIED BY
‘mypassword’ WITH GRANT OPTION; GRANT ALL PRIVILEGES ON . TO
‘root’@’10.10.40.54’ IDENTIFIED BY ‘123456’ WITH GRANT OPTION;
