Everything in my droplet uninstalled?

Posted on April 24, 2020

I ssh’ed into my droplet and everything was… green? the directories are usually blue and I have a ruby on rails API on there. When I try to run it, it says that rails isn’t installed…But I ran it yesterday… and the day before… When I ssh into my other droplet it doesn’t have this issue so… I don’t know what to do. This happened before so I just destroyed that droplet and got a new one but now it’s happening again and I dont’ want to keep getting new droplets so…I really don’t understand whats going on :(

Hello,

This sounds like a command is being executed which causes the issue for you. There are a few things that I would recommend checking:

Check the list of last logged in users. You can do that with this command:

last

The output will look like this:

root     pts/0        USER_IP     Fri Apr 24 15:11   still logged in
root     pts/0        USER_IP     Thu Apr 23 17:23 - 20:49  (03:26)
root     pts/0        USER_IP     Wed Apr 22 16:25 - 20:12  (03:47)
root     pts/0        USER_IP     Wed Apr 22 08:40 - 11:19  (02:39)

That way you will be able to tell if someone from anther IP address is accessing your Droplet.

Check the last commands that were executed on the Droplet:

history

That way you will be able to see which command caused the problem

Enable backups for your Droplet, that way you will be able to restore to a working backup rather than starting from scratch every time there is a problem
Configure your firewall so that you could restrict some of the access to your Droplet. You can take a look at this tutorial here on how to do that:
