If you have nginx listening on port 80, you should put Thin listening
on another port. It is probably best to put it listening on an address
like 127.0.0.1.

The upstream is whatever Thin is listening on, and should include a specific
address, not 0.0.0.0. (The "upstream" configuration does nothing until
it is referenced in the proxy_pass directive which follows.)

The important location{} block is the one that refers to all urls that
should be handled by Thin (and refers to no urls that should not be
handled by Thin).

In that location{}, you will want something like

  proxy_pass http://mywebapp_thin;

or maybe

  proxy_pass http://mywebapp_thin/;

Depending on how Thin responds, you may also want some proxy_set_header
lines.

http://nginx.org/r/location
http://nginx.org/r/proxy_pass
http://nginx.org/r/proxy_set_header

Good luck with it,
