nginx rewrite file location
===

In my application, I am trying to link `http://domain.com/accounts/login` and `/accounts/register` to `http://domain.com/accounts.php?action=$` where `$` is this: `http://domain.com/accounts/$`

I don't know where to define the rewrite and what to put down.

I have access to the entire VPS via SSH, but I'm not sure what file to edit. So where is the file located?

I checked the /opt/ folder, it appears to be empty. I might be running lighttpd, so can you help me out for both instances? Otherwise, can you tell me how to check whether I use lighttpd.
