Deploying a Ruby application on Passenger + Apache

Question

I am trying to run a rails application on Apache2. When viewing the site on the browser it list all the files in the directory instead of running the application. The error log for Apache shows a message

[Fri Nov 20 15:15:04.274304 2015] [mpm_event:notice] [pid 7656:tid 139998747531136] AH00489: Apache/2.4.7 (Ubuntu) Phusion_Passenger/5.0.21 configured -- resuming normal operations

Conf:

        Require all denied

        AllowOverride None
        Require all granted

</Directory>

<VirtualHost *:80>
    ServerName www.hroot.ncl.ac.uk

    # Tell Apache and Passenger where your app's 'public' directory is
    DocumentRoot /home/adminuser/hroot/

    PassengerRuby /usr/local/rvm/gems/ruby-2.1.2/wrappers/ruby

    # Relax Apache security settings
    <Directory /home/adminuser/hroot>
      Allow from all
      Options -MultiViews
      # Uncomment this if you're on Apache > 2.4:
      Require all granted
    </Directory>
</VirtualHost>

I am now getting this message in the log file.

Its difficult to guide unless we know what steps you have followed and what you have tried so far. If you want some tutorial on this I love this blog https://www.digitalocean.com/community/tutorials/how-to-setup-a-rails-4-app-with-apache-and-passenger-on-centos-6 — Pardeep Dhingra, Nov 24 '15 at 11:16
Thanks @PardeepDhingra I am following the instructions on this [link](https://www.phusionpassenger.com/library/deploy/apache/deploy/ruby/) after reading the blog it states something about having httpd installed which i don't have. I am running ubuntu 14.4 LTS. — user5576922, Nov 24 '15 at 11:53
Can you paste your confing file and how you have loaded passenger module in apache.conf — Pardeep Dhingra, Nov 24 '15 at 11:54
Apache and httpd both are same if you have apache installed its fine. — Pardeep Dhingra, Nov 24 '15 at 12:19
Your directoy url is wrong. It should point to public folder of your application. — Pardeep Dhingra, Nov 24 '15 at 12:21
Apologies i have modfied the code sense then the code i am running now as below: — user5576922, Nov 24 '15 at 12:38
You mean your url is correct and you are having DocumentRoot and Multiviews too and still its not working? — Pardeep Dhingra, Nov 24 '15 at 12:39
I am very sorry this is an old code. How can paste my code in the comment. It's characters too long! Sorry. — user5576922, Nov 24 '15 at 12:48
this should point to public folder `/home/adminuser/hroot/public` — Pardeep Dhingra, Nov 24 '15 at 13:00
@PardeepDhingra Pointing to this directory i get the above error message in the log file. — user5576922, Nov 24 '15 at 13:17
