Deploying Rails with subdomains using capistrano to an nginx/unicorn setup -- how?

I've been following Ryan B's VPS deployment railscast:

http://railscasts.com/episodes/335-deploying-to-a-vps

nginx.conf file he suggest using doesn't work with subdomains. This is what he shows:

upstream unicorn {
  server unix:/tmp/unicorn.blog.sock fail_timeout=0;
}

server {
  listen 80 default deferred;
  # server_name example.com;
  root /home/deployer/apps/<app name>/current/public;

  location ^~ /assets/ {
    gzip_static on;
    expires max;
    add_header Cache-Control public;
  }

  try_files $uri/index.html $uri @unicorn;
  location @unicorn {
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host;
    proxy_redirect off;
    proxy_pass http://unicorn;
  }

  error_page 500 502 503 504 /500.html;
  client_max_body_size 4G;
  keepalive_timeout 10;
}

Does anyone know how to set things up to support subdomains?

It turns out (at least with linode.com), that handeling wildcard subdomains is pretty straight forward. You just need to add a * host to the A record.

Also, in nginix, what I did was replaced:

# server_name example.com;

with:

server_name localhost;

I'm not sure that's even needed.

My actual issue had nothing to do with either the host or nginx. My situation was that I was using a random hashed URL as a security token during registration (so a user can't hijack an existing subdomain), but the type of hash I was using had issues so I needed to modify it.

I wasn't seeing any errors, I was just being redirected back to the signup page -- as is the correct behavior when the hashed URL has problems / doesn't match.

Anyway, once I fixed that, the whole subdomain thing was a non-issue.

Hope this helps anyone else who uses hashed URLs, subdomains, and is generally new to deployment.

Cheers.

You can uncomment line:

# server_name example.com;

replace example.com with your domain and add:

server_name example.com *.example.com; or

server_name example.com blog.example.com;

Now all requests to domain and subdomains will go to the rails
