I am building a test app using AWS EC2 with Nginx and Puma following this tutorial

https://www.sitepoint.com/deploy-your-rails-app-to-aws/

I am also able to deploy the app successfully with Capistrano. The app also works in development. I am using Rails 5 and Ruby 2.3.1 in development and production.

At this moment I have two pages working in development but not working in production.

In production when using this URL

http://ec2-54-226-156-103.compute-1.amazonaws.com/

I am getting

This is the default index.html page that is distributed with nginx on the Amazon Linux AMI. It is located in /usr/share/nginx/html.

instead of my home page.

And when I am using this URL

http://ec2-54-226-156-103.compute-1.amazonaws.com/contacts

I am getting

nginx error!
The page you are looking for is not found.
Something has triggered missing webpage on your website. This is the default 404 error page for nginx that is distributed with the Amazon Linux AMI. It is located at /usr/share/nginx/html/404.html
You should customize this error page for your own site or edit the error_page directive in the nginx configuration file /etc/nginx/nginx.conf.

Don't k know how to fix this.

Here are my config files for Nginx.

  error_page 500 502 503 504 /500.html;
  client_max_body_size 4G;
  keepalive_timeout 10;
}

Don't know how to fix these Nginx settings in order to have the app working properly and Nginx serving pages from the app?

If this may be of any help, here is the puma config file from the folder /home/deploy/contactbook/shared

cat puma.rb

#!/usr/bin/env puma

directory '/home/deploy/contactbook/current'
rackup "/home/deploy/contactbook/current/config.ru"
environment 'production'

pidfile "/home/deploy/contactbook/shared/tmp/pids/puma.pid"
state_path "/home/deploy/contactbook/shared/tmp/pids/puma.state"
stdout_redirect '/home/deploy/contactbook/shared/log/puma_error.log', '/home/deploy/contactbook/shared/log/puma_access.log', true

threads 0,8

bind 'unix:///home/deploy/contactbook/shared/tmp/sockets/puma.sock'

workers 0

prune_bundler

on_restart do
  puts 'Refreshing Gemfile'
  ENV["BUNDLE_GEMFILE"] = "/home/deploy/contactbook/current/Gemfile"
end

The problem is server_name localhost; in sites-available/default.

I means nginx will only use that server block for requests where the Host header matches "localhost".
For testing, you can set it to server_name _; which is the catch-all.

Eventually, you will want to set it to your sites name, like server_name ec2-54-226-156-103.compute-1.amazonaws.com, but that can wait until you have a domain name.

Something has triggered missing webpage on your website. This is the default 404 error page for nginx that is distributed with Red Hat Enterprise Linux. It is located /usr/share/nginx/html/404.html

You should customize this error page for your own site or edit the error_page directive in the nginx configuration file /etc/nginx/nginx.conf.

For information on Red Hat Enterprise Linux, please visit the Red Hat, Inc. website. The documentation for Red Hat Enterprise Linux is available on the Red Hat, Inc. website.
