Rails application not loading after deploy to EC2 using Capistrano

Question

I setup an Amazon EC2 Ubuntu 14.04 instance and deployed my Rails application using Capistrano with Passenger in Apache following the guide in Passenger website, tried to follow everything stated except that I have different app name and directory: /var/www/<my_app_name>.

After some configurations the deployment has finally success and when I try running Rails console in my app folder it's working fine, but when I try to access my app through IP address in web browser it does not load at all, browser returning ERR_CONNECTION_TIMED_OUT error. I have restarted Apache several times but it's still not working. Maybe something is missing out or configuration error with Apache/Passenger.

This is my Apache error log from /var/log/apache2/error.log:

While my access.log is empty.

This is my app configuration for Apache in /etc/apache2/sites-enabled/my_app.conf:

<VirtualHost *:80>
    ServerName <my_ip_address>

    # Tell Apache and Passenger where your app's 'public' directory is
    DocumentRoot /var/www/my_app/current/public

    PassengerRuby /usr/local/rvm/rubies/ruby-2.2.1/bin/ruby

    # Relax Apache security settings
    <Directory /var/www/my_app/current/public>
      Allow from all
      Options -MultiViews
      Require all granted
    </Directory>
</VirtualHost>

Any help is much appreciated. Thanks in advance.

Update 1: When I tried to see the status of Passenger using passenger-status:

Phusion Passenger is currently not serving any applications.

I tried to get my application hooked to Passenger by touching restart.txt like so:

$sudo touch /var/www/my_app/current/tmp/restart.txt

But it's not working.

Answer 1

The problem is on instance settings as pointed out in this SO question. EC2 instance is not allowing public HTTP access by default:

1. Click Instances in ec2 page navigation tab

2. Scroll through your instance record to find the security group. Click on the security group.

3. Select "Inbound" tab for the security group and make sure the following rule exists.

   HTTP TCP 80 0.0.0.0/0
