mysql 远程访问不行解决方法 Host is not allowed to connect to this MySQL server

授权

1、例如，你想myuser使用mypassword从任何主机连接到mysql服务器的话。

GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'%' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;

2、如果你想允许用户myuser从ip为192.168.1.3的主机连接到mysql服务器，并使用mypassword作为密码
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;
