What takes up space on a VDS server (Ubuntu 20.04)?

Question

linux

Hello.
In general, I bought myself a VDS server on timeweb for 10 GB. Raised my sites on nginx, NodeJS (ExpressJS, React) and did nothing else, and the place is constantly decreasing. I tried deleting logs in /var/log, but I no longer know where and what to look for. I did not make any changes to the code, and there are fewer and fewer places every day. Can you please tell me where else to look for files that can be cleared?

Answer 1

ncdu will describe everything beautifully for you

Answer 2

configure logrotate correctly.... Otherwise, you can get into a situation - the nginx log was deleted, but they didn't tell him about it... and he writes to it...

Answer 3

The du command will help you...
