        listen 80 default_server;
        listen [::]:80 default_server ipv6only=on;
        server_name dragonfest.ru www.dragonfest.ru;
        passenger_enabled on;
        rails_env production;
        root /usr/share/nginx/public;
        index index.html index.htm;
        error_page 500 502 503 504  /50x.html;
        autoindex on;
        # Make site accessible from http://localhost/
        #server_name localhost;

The following lines are uncommented in /etc/nginx/nginx.conf:

passenger_root /usr/lib/ruby/vendor_ruby/phusion_passenger/locations.ini;
