嗯.我认为***的方法是在尝试通过NetBeans连接到远程数据库之前设置端口转发.

Hmm. I reckon the best way for you to do this is to set up port forwarding before attempting to connect to your remote database via NetBeans.

我不确定您使用的是什么操作系统，但是假设您使用的是Linux，请按照以下步骤操作:

I'm not sure what OS your using but, assuming you are using some flavour of Linux here are the steps to take:

1)将本地端口转发到远程MySQL数据库服务器 打开一个终端窗口，然后输入:

1) Forward a local port to your remote MySQL Database server Open up a terminal window and type:

sudo ssh -L 6666:127.0.0.1:3306 <your_SSH_username<@<remoteserver.com>

系统将提示您输入SSH密码.输入它.

You'll be prompted for your SSH password. Enter it.

2)在Netbeans中，转到Services并使用以下凭据建立新的MySQL数据库连接:

2) In Netbeans go to Services and set up a new MySQL database connection with the following credentials:

主机:127.0.0.1

host: 127.0.0.1

用户名:root(我假设远程MySQL数据库允许远程root连接?)

username: root (I'm assuming that the remote MySQL db allows remote root connections?)

密码:密码(我想您必须为要连接的MySQL数据库输入密码吗?！)

password: password (I guess you must have a password for the MySQL database that you're connecting to?!)

jdbc网址应如下所示:

The jdbc url should look something like this:

jdbc:mysql://127.0.0.1:6666?username=root&password=<your_remote_db_root_password>

祝您好运，希望对您有帮助！

Good luck and I hope this helps!
