解决:1130-host . is not allowed to connect to this MySql server,MySQL报错

1. 改表法。

可能是你的帐号不允许从远程登陆，只能在localhost。这个时候只要在localhost的那台电脑，登入MySQL后，更改 "mysql" 数据库里的 "user" 表里的 "host" 项，从"localhost"改称"%"

mysql -u root -p

mysql>use mysql;

mysql>update user set host = '%' where user = 'root';

mysql>select host, user from user;

 

2. 授权法。

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;

FLUSH   PRIVILEGES;

如果你想允许用户myuser从ip为192.168.1.6的主机连接到mysql服务器，并使用mypassword作为密码

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

FLUSH   PRIVILEGES;

如果你想允许用户myuser从ip为192.168.1.6的主机连接到mysql服务器的dk数据库，并使用mypassword作为密码

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

FLUSH   PRIVILEGES;
