Striving to make a RoR app (passenger, nginx) work on EC2

Question

I've installed RoR, ruby, passenger and nginx on EC2 Ubuntu instance. Now I'm striving to make it work and be accessible only for the ec2's address which looks this http://ec2-11-222-333-44.ap-southeast-2.compute.amazonaws.com/

So I've done everything needed. However, I can't figure out how to setup nginx. Here my /etc/nginx/nginx.conf:

user www-data;
worker_processes 4;
pid /run/nginx.pid;

events {
  worker_connections 768;
  # multi_accept on;
}

http {

  ##
  # Basic Settings
  ##

  sendfile on;
  tcp_nopush on;
  tcp_nodelay on;
  keepalive_timeout 65;
  types_hash_max_size 2048;
  # server_tokens off;

  # server_names_hash_bucket_size 64;
  # server_name_in_redirect off;

  include /etc/nginx/mime.types;
  default_type application/octet-stream;

  ##
  # Logging Settings
  ##

  access_log /var/log/nginx/access.log;
  error_log /var/log/nginx/error.log;

  ##
  # Gzip Settings
  ##

  gzip on;
  gzip_disable "msie6";

  # gzip_vary on;
  # gzip_proxied any;
  # gzip_comp_level 6;
  # gzip_buffers 16 8k;
  # gzip_http_version 1.1;
  # gzip_types text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript;

  ##
  # nginx-naxsi config
  ##
  # Uncomment it if you installed nginx-naxsi
  ##

  #include /etc/nginx/naxsi_core.rules;

  ##
  # nginx-passenger config
  ##
  # Uncomment it if you installed nginx-passenger
  ##

  #passenger_root /usr;
  #passenger_ruby /usr/bin/ruby;

  ##
  # Virtual Host Configs
  ##

  include /etc/nginx/conf.d/*.conf;
  include /etc/nginx/sites-enabled/*;
}


#mail {
# # See sample authentication script at:
# # http://wiki.nginx.org/ImapAuthenticateWithApachePhpScript
# 
# # auth_http localhost/auth.php;
# # pop3_capabilities "TOP" "USER";
# # imap_capabilities "IMAP4rev1" "UIDPLUS";
# 
# server {
#   listen     localhost:110;
#   protocol   pop3;
#   proxy      on;
# }
# 
# server {
#   listen     localhost:143;
#   protocol   imap;
#   proxy      on;
# }
#}


server {
        listen       80;
        server_name  localhost;
        root   /home/ubuntu/my_app/public;
        passenger_enabled on;

        #error_page  404              /404.html;

        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   /home/ubuntu/my_app/public;
        }
}

My questions:

Do I have to have an index.html in /my_app/public directory? If so then why? It's a Rails app, not a static app?
Do I have to specify root /home/ubuntu/my_app/public; If so what does it have to do with the /public directory? Again, it's a Rails app, not a static app?
What should I do just to make it work?

And nothing. Go do that. – Michael Hampton Sep 14 '14 at 19:46 — Michael Hampton, Sep 14 '14 at 19:46
@MichaelHampton, can you do that for me? – Incerteza Sep 19 '14 at 02:06 — Incerteza, Sep 19 '14 at 02:06
Sorry, I won't work on your server without payment... :) – Michael Hampton Sep 19 '14 at 02:08 — Michael Hampton, Sep 19 '14 at 02:08
@MichaelHampton, why not? Aren't you considerate? – Incerteza Sep 19 '14 at 03:58 — Incerteza, Sep 19 '14 at 03:58

Some Answers:

No.
Only specify root at the start of your server { block, check out Nginx Pitfalls
I'm pretty sure it's the commented section in your nginx.conf:
```
#passenger_root /usr;
#passenger_ruby /usr/bin/ruby;
```

You are not pointing them to Passenger + Ruby. (What does nginx run when it gets a request? Nothing, that's what.)

Check out this blog Setup RoR + Passenger on AWS for setting up RoR + Passenger

Below is a copy of a working nginx.conf and a sample virtual directory for your reference.
