Mysql:is not allowed to connect to this MySQL server

如果你想連接你的mysql的時候發生這個錯誤：

ERROR 1130: Host '192.168.1.3' 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;

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;
