--------------------------------------------
Almost there!

Please edit your Apache configuration file, and add these lines:

   LoadModule passenger_module /home/ec2-user/.rbenv/versions/2.4.0/lib/ruby/gems/2.4.0/gems/passenger-5.1.2/buildout/apache2/mod_passenger.so
   <IfModule mod_passenger.c>
     PassengerRoot /home/ec2-user/.rbenv/versions/2.4.0/lib/ruby/gems/2.4.0/gems/passenger-5.1.2
     PassengerDefaultRuby /home/ec2-user/.rbenv/versions/2.4.0/bin/ruby
   </IfModule>

After you restart Apache, you are ready to deploy any number of web
applications on Apache, with a minimum amount of configuration!
