message from server: "Host is not allowed to connect to this MySQL server"解決辦法

報錯:1130-host … is not allowed to connect to this MySql server

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 -pvmwaremysql>use mysql;

mysql>update user set host = ‘%’ where user = ‘root’;

mysql>select host, user from user;

mysql>FLUSH RIVILEGES

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 ‘myuser’@‘192.168.1.3’ IDENTIFIED BY ‘mypassword’ WITH GRANT OPTION;

FLUSH   PRIVILEGES;

如果你想允許用戶myuser從ip爲192.168.1.3的主機連接到mysql服務器的dk數據庫，並使用mypassword作爲密碼

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

FLUSH   PRIVILEGES;
