MySQL 1130...is not allowed to connect to this MySql server

1、修改数据表
帐号不允许从远程登陆，只能在localhost。

登入mysql后，更改 "mysql" 数据库里的 "user" 表里的 "host" 项，从"localhost"改称"%"。

mysql -uroot -p

mysql>use mysql;

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

mysql>select host, user from user;

重启MySQL服务

2、授权

mysql -uroot -p 

mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION  

mysql>FLUSH PRIVILEGES
