如何解決：
關閉防火墻
service iptables stop
1。 改表法。

可能是你的帳號不允許從遠程登陸，只能在localhost。登錄安裝的那臺電腦，登入mysql後，更改 "mysql" 數據庫裏的 "user" 表裏的 "host" 項，從"localhost"改稱"%"

mysql>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;

FLUSH PRIVILEGES;

如果你想允許用戶myuser從ip為192.168.1.6的主機連接到mysql服務器，並使用mypassword作為密碼

GRANT ALL PRIVILEGES ON *.* TO ‘myuser‘@‘192.168.1.3‘ IDENTIFIED BY ‘mypassword‘ WITH GRANT OPTION;

FLUSH PRIVILEGES;

如果你想允許用戶myuser從ip為192.168.1.6的主機連接到mysql服務器的dk數據庫，並使用mypassword作為密碼

GRANT ALL PRIVILEGES ON dk.* TO ‘myuser‘@‘192.168.1.3‘ IDENTIFIED BY ‘mypassword‘ WITH GRANT OPTION;

FLUSH PRIVILEGES;

Mysql host '192.168.1.1' is not allowed to connect to this mysql server
