How to set up SSH connection from remote database cluster to MySQL workbench

I have a MySQL database cluster set up that I can connect to successfully via the command line (by running the flags in the terminal).

I’d like to be able to connect to the MySQL Workbench. I looked at this tutorial but I must be missing some kind of prerequisite that I cannot figure out.

I entered:
SSH Hostname: redactedname-do-user-redactednumber-0.b.db.ondigitalocean.com:25060
SSH Username: doadmin
SSH Password: redactedPassword
MySQL Hostname: 127.0.0.1
MySQL Server Port: 3306
Username: root

The error I get is:

Failed to Connect to MySQL at 127.0.0.1:3306 through SSH tunnel at doadmin@redactedname-do-user-redactednumber-0.b.db.ondigitalocean.com:25060 with user root
Cannot open SSH Tunnel: Socket error: Connection reset by peer

I’ve been working on this issue for quite a long time trying to open an SSH tunnel manually in the terminal, using this template for the command: ssh -L 8888:127.0.0.1:3306 st-user@my-remote-server.host.

This command gives me:
“Permission denied (publickey)”

I also generated an SSH Key file and have linked that in the Workbench but that has not helped me make progress.

[This article](http://)

Is this an issue from Digital Ocean rejecting the connection? Do I need to set up some SSH tunnel manually? Why is it refusing connection?

Much appreciated.

Hi there,

The tutorial with the remote MySQL connection via SSH would not work for Managed MySQL Clusters as the clusters do not come with SSH access.

The tutorial would work if you had MySQL installed on a regular Droplet.

What you could do instead is to specify the MySQL Cluster details as usual without using the SSH tunnel option in your SQL client.

Let me know if you have any questions.

Bobby

  • Hi Bobby,

    Thanks so much for the response! I realized this in a roundabout way… I downloaded a different query manager, TablePlus, which has a feature to copy/paste the connection string and fills out the connection fields automatically, which enabled me to connect. That makes sense why I wasn’t succeeding in making the connection via SSH in the Workbench.
