Question

Can't connect to mySQL server after the hacker

My site has been down over ten days now since the hacker did his damage. He wiped out several tables in my database. Right after it happened I was still able to get into the mySQL server using my macOS Querious app, but not anymore. I’m not sure what the hacker did to cause this subsequent change. I can successfully get in if I use the command line to SSH into the droplet, then login with a user on the mySQL server. But I just can’t accomplish this in the mySQL app.

I’ve been researching this for days on end with no success. Can someone point me to an article that would help me troubleshoot this problem? I do have an inbound rule in the Digital Ocean firewall for port 3306. I also have this port open in ufw.

Here is the error I’m getting in the Querious app:

mySQL connection failed Can’t connect to mySQL server on x.x.x.x (61) (2003) Double check the mySQL host and port settings are correct, the server is running, and that no firewall settings are blocking access to the server.

Thank you!!

Hi @spendlove,

There are a few possibilities, the best one would be to use a backup if you have one. If database tables have been removed it might be very hard if not impossible to restore the structure of the database and its contents.

If a backup is not an option, then you can try changing the password of the mysql user you are using and try again afterward.

Additionally, try to run

  1. telnet YourDropletIP 3306

from your laptop to see if you would be able to connect. If you do, then you have access to the port but the user and password are the problem. If you can’t connect then it’s your firewall.
