404 Not found error in deploying a Rails app with Apache2 and Passenger

Question

probably a matter of simple adjustment but I have no idea whats going wrong.

I want a host to be a server for my rails application, which was deployed using Capistrano 3.2.1. This is a Unix machine running Apache/2.2.15, named eng-perf (corporate internal machine, so no www.address.com syntax at the moment).

I followed this guide and the entire installation process went without any trouble. I edited the configuration file so that it looks like this:

<VirtualHost *:80>
  ServerName eng-perf
  # !!! Be sure to point DocumentRoot to 'public'!
  DocumentRoot /var/www/eng_performance/current/public/
  <Directory /var/www/eng-performance/current/public/>
     # This relaxes Apache security settings.
     AllowOverride all
     # MultiViews must be turned off.
     Options -MultiViews
     # Uncomment this if you're on Apache >= 2.4:
     #Require all granted
  </Directory>
</VirtualHost>

That gave me this error:

Not Found

The requested URL / was not found on this server.

Next, I tried following the guide by creating the dummies application- as explained here , and changed the configuration file to be:

<VirtualHost *:80>
  ServerName eng-perf
  # !!! Be sure to point DocumentRoot to 'public'!
  DocumentRoot /var/www/rack_example/public/
  <Directory /var/www/rack_exmaple/public/>
     # This relaxes Apache security settings.
     AllowOverride all
     # MultiViews must be turned off.
     Options -MultiViews
     # Uncomment this if you're on Apache >= 2.4:
     #Require all granted
  </Directory>
</VirtualHost>

That resulted the exact same Not Found error. So, I guess I'm missing something quite simple..

Also, I tried to restart the apache server and prompted: httpd: Could not reliably determine the server's fully qualified domain name, using the.machine.ip.addr for ServerName As a result I changed the ServerName field to be this address- but that didn't work either.

Update:

Following Rich's advise, I updated the configuration file so now I get this output:

We use the following:

#etc/apache2/apache2.conf
<VirtualHost *:80>
   ServerName eng-perf.com

   DocumentRoot /var/www/rack_example/plublic
   <Directory /var/www/rack_example/public>
      Allow from all
      Options -MultiViews
   </Directory>

   ScriptAlias /cgi-bin/ /usr/lib/cgi-bin
   <Directory "/usr/lib/cgi-bin">
       AllowOverride None
       Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
       Order allow,deny
       Allow from all
   </Directory>
</VirtualHost>

I suspect the problem lies with your not calling your domain correctly. It's going to get confused about what it's looking for on the request
