cd pawn-parade
gem install mysql2 -v '0.3.15'
bundle install
rake db:migrate

For non-production environments, launch the app via rails server, to bring it up on http://localhost:3000

rails server

For production environments, use unicorn

gem install unicorn

We'll run nginx as rails

vi /etc/nginx/nginx.conf

Change "user nginx;" to "user rails;"

vi /etc/nginx/conf.d/default.conf

upstream app {
    server unix:/tmp/unicorn.pawn-parade.sock fail_timeout=0;
}

server {
  listen 80 default_server deferred;
  server_name castle-chess.org;
  root /home/rails/pawn-parade/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 20M;
  keepalive_timeout 10;
}

Now run unicorn:

bundle exec unicorn -E production -c config/unicorn.rb -D 

And restart nginx:

systemctl restart nginx.service

This doesn't cover SSL Cert installation.
