I'm having some trouble getting my rails app to run in production. As I've coded rails before but haven't deployed much it's probably something in my configs and/or deployment process.
Everything runs fine locally in development. All tests pass, I can see the routes and access them at localhost. When in production (rails 4, nginx, unicorn on CentOS) I'm getting 500 errors on the very same routes.
When I rake routes on the server I see all the same routes as when in development. Rake routes on the server returns (shortened from the full list of routes):
Prefix Verb URI Pattern Controller#Action
companies GET /companies(.:format) companies#index
POST /companies(.:format) companies#create
new_company GET /companies/new(.:format) companies#new
edit_company GET /companies/:id/edit(.:format) companies#edit
company GET /companies/:id(.:format) companies#show
PATCH /companies/:id(.:format) companies#update
PUT /companies/:id(.:format) companies#update
DELETE /companies/:id(.:format) companies#destroy
Which as you can probably guess comes from resources :companies
But http://sortinghat.foo.com/companies gives me the rails 500 page on production (foo is obviously not the domain but I've just replaced the real domain).
I am at a loss having searched on here and the web for ideas, having read lots of "how to deploy rails" blog posts, and have looked at lots of config files (you'll see these are ones I copied from elsewhere but it all seems pretty standard). I'm probably missing something obvious. I'm not seeing any issues in the logs.
The only clue I have is that I don't have an /etc/nginx/sites-enabled directory and it looks like capistrano wants one, but I didn't see any errors during cap deploy (except the cleanup one I note at the bottom). In this case it's the only site being run so I don't need a virtual host and didn't think I needed it so wasn't concerned.
Thanks in advance for any help.
Here's my nginx.config

My unicorn.rb
# Taken from http://www.sitepoint.com/deploying-your-rails-app-to-the-cloud-with-unicorn-nginx-and-capistrano/

And my deploy.rb (Note: I made some things world readable with the chmod 777 as a quick hack. I'm just trying to get this running internally to run a test all behind a firewall. I can probably take those out but I doubt they're hurting anything right now.)

cap deploy works with only one error, but it's just a problem with permissions cleaning up old releases. ( cap deploy:cold ran fine)
