Run Rails with Passenger on Apache with Plesk

Question

I have everything installed as per this tutorial: https://www.digitalocean.com/community/tutorials/how-to-setup-a-rails-4-app-with-apache-and-passenger-on-centos-6

But when I go to the website, I get an error, and in the error log it shows this:

[ 2015-02-26 16:17:47.3041 28207/7f7326058780 agents/Watchdog/Main.cpp:728 ]: All Phusion Passenger agents started!

Can anyone help?

The config.ru file was auto generated by rails, and it has these lines:

# This file is used by Rack-based servers to start the application.

require ::File.expand_path('../config/environment',  __FILE__)
run BlahBlah::Application

Answer 1

Your problem can be related to the following things:

• config.ru file is not exists by the specified path

  Try to execute command for check this:

   ls -la /var/www/vhosts/blah.blah/httpdocs/config.ru 

• Passenger doesn't have permissions to read this file

  Try to execute command for check this:

   namei -lm /var/www/vhosts/blah.blah/httpdocs/config.ru 

PS I noticed you are using shared hosting. Don't use them if you want to avoid a lot of different problems. Use VPS servers instead. Like Digital Ocean or Linode for Rails applications.
