Trying to setup a DigitalOcean VPS droplet (Ubuntu 12.10
rails4/ruby2.0.0p353/nginx/unicorn) with one app. I think unicorn is my
current barrier--nginx seems to be running, waiting to forward responses to
unicorn on :8080, but there's some stock setup I'm not understanding. Do I
need to tweak the *unicorn* run or somehow get *unicorn_rails* working? My
basic capistrano deploy works, at least enough to get the files to the
server. My goal here is at least getting the site running to the point of
postgres errors i.e. the db doesn't yet exist, and that's another challenge.

    - DigitalOcean sets up an app at /home/rails out of the box, which runs
    fine.
    - I updated /etc/nginx/sites-enabled/default (below) to my app's
    properties and restarted
    - I added config/unicorn.rb to my site and try to restart
    unicorn/unicorn_rails/etc, still can't get it right

*/etc/nginx/sites-enabled/default* (my changes)

upstream unicorn {

server unix:/tmp/.sock fail_timeout=0;

}

server {

listen 80;

root /var/www/myapp/current/public;

server_name mysite.com;

index index.htm index.html;

location / {

try_files $uri/index.html $uri.html $uri @app;

}

e|pdf|ppt|txt|tar|mid|midi|wav|bmp|rtf|js|mp3|flv|mpeg|avi)$ {

}

location @app {

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

proxy_set_header Host $http_host;

proxy_redirect off;

proxy_pass http://app_server;

     }

}

*tail unicorn.log* (the boldface error log below is what I think happens
when I make a request to the site and I get the public/500.html)
