mysql远程连接报错： Host * is not allowed to connect to this MySQL server，解决方法

localhost改成%

1.进入mysql的BIN目录

注：root为管理员用户名，password为用户root的密码：

mysql -u root -p password

mysql>use mysql;

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

mysql>flush privileges;

注：这时候连接此服务器的mysql客户端需要重新启动下，然后再连接此服务器。

mysql> select host,user,password from user;
