当我尝试使用命令行mysql -h <remote-ip> -u any_existing_users -p
或任何其他 mysql 客户端(如 phpmyadmin)连接远程 MySQL 服务器时,它不起作用,错误提示是
ERROR 2003 (HY000) Can't connect to MySQL server on '<remote-ip>' (61)
但是,当我尝试ssh <remote-ip>
通过本地连接 MySQL时mysql -u root -p
,没有问题。
这是用户表(SELECT User, Host FROM mysql.user;
)的一部分:
+------------------+----------------+
| User | Host |
+------------------+----------------+
| root | % |
| other_users | <remote-ip> |
| root | localhost |
+------------------+----------------+
这是iptable:

所以有什么问题?
