unicorn + nginx setup + ssl

unicorn.rb

unicorn.rb
-----------------------------------

application     = "jarvis"
remote_user     = "vagrant"
env = ENV["RAILS_ENV"] || "development"
RAILS_ROOT = File.join("/home", remote_user, application)

worker_processes 8
timeout 30
preload_app true

working_directory RAILS_ROOT
listen File.join(RAILS_ROOT, "tmp/unicorn.sock"), :backlog => 64
pid_path = File.join(RAILS_ROOT, "tmp/pids/unicorn.pid")
pid pid_path

stderr_path File.join(RAILS_ROOT, "log/unicorn-err.log")
stdout_path File.join(RAILS_ROOT, "log/unicorn-err.log")

before_fork do |server, worker|
  if defined?(ActiveRecord::Base)
    ActiveRecord::Base.connection.disconnect!
  end
  old_pid_path = "#{pid_path}.oldbin"
  if File.exists?(old_pid_path) && server.pid != old_pid_path
    begin
      Process.kill("QUIT", File.read(old_pid_path).to_i)
    rescue Errno::ENOENT, Errno::ESRCH
      # someone else did our job for us
    end
  end
end

after_fork do |server, worker|
  if defined?(ActiveRecord::Base)
    ActiveRecord::Base.establish_connection
  end

  # worker processes http://devmull.net/articles/unicorn-resque-bluepill
  # rails_env = ENV['RAILS_ENV'] || 'production'
  # worker.user('app', 'app') if Process.euid == 0 && rails_env == 'production'
end


nginx
----------------------------------
upstream dev.jarvis.com {
  server unix:/home/vagrant/jarvis/tmp/unicorn.sock fail_timeout=0; 
}

server {
    listen 443 default;

    ssl on;
    ssl_certificate    /home/vagrant/ssl/server.cer;
    ssl_certificate_key     /home/vagrant/ssl/server.key;

    server_name dev.jarvis.com;

    root /home/vagrant/jarvis/public;
    try_files $uri/index.html $uri @unicorn;

    location @unicorn {
      proxy_redirect off;
      proxy_set_header X-Forwarded-Proto https;
      proxy_pass http://dev.jarvis.com;
    }

    error_page 502 503 /maintenance.html;
    error_page 500 504 /500.html;
    keepalive_timeout 5;
}

I am looking for a Unicorn + nginx + http > https example.

Thank you!
