问题描述

This should be dead simple, but I cannot get it to work for the life of me.
I'm just trying to connect remotely to my MySQL server.

Connecting as:

    mysql -u root -h localhost -p

works fine, but trying:

    mysql -u root -h 'any ip address here' -p

fails with the error:

    ERROR 1130 (00000): Host ''xxx.xx.xxx.xxx'' is not allowed to connect to this MySQL server

In the mysql.user table, there is exactly the same entry for user 'root' with host 'localhost' as another with host '%'.

I'm at my wits' end and have no idea how to proceed.Any ideas are welcome.

解决方案

Possibly a security precaution. You could try adding a new administrator account:

mysql> CREATE USER 'monty'@'localhost' IDENTIFIED BY 'some_pass';
mysql> GRANT ALL PRIVILEGES ON *.* TO 'monty'@'localhost'
    ->     WITH GRANT OPTION;
mysql> CREATE USER 'monty'@'%' IDENTIFIED BY 'some_pass';
mysql> GRANT ALL PRIVILEGES ON *.* TO 'monty'@'%'
    ->     WITH GRANT OPTION;

Although as Pascal and others have noted it's not a great idea to have a user with this kind of access open to any IP. If you need an administrative user, use root, and leave it on localhost. For any other action specify exactly the privileges you need and limit the accessibility of the user as Pascal has suggest below.
