nginx with unicorn on a subdirectory

gistfile1.txt

Unicorn conf can be your normal stuff, set it to the same port as "upstream app_unicorn"

The trick is now to start it with the env variable: RAILS_RELATIVE_URL_ROOT=/sub
So the full command I use is:

RAILS_ENV=production RAILS_RELATIVE_URL_ROOT=/sub bundle exec unicorn -c unicorn_config.rb -D

nginx.cont

upstream app_unicorn {
  server 127.0.0.1:8001 fail_timeout=0;
}

server {
  root /someapp/path/current/public;

  # Handle assets and direct requests to the right place
  location ~* /sub(/.*)? {
    try_files $1/index.html $1.html $1 @app_proxy;
  }

  location @app_proxy {
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host;
    proxy_redirect off;
    proxy_pass http://app_unicorn;
  }

}
