Problems installing Ruby on rails with apache2 on ubuntu

Using the guide found on http://www.modrails.com/install.html I installed Ruby on rails and phusion-passenger for deployment with apache2. (on ubuntu-server) (This is not the development server). The rails script works fine when i run "rails -s", but when I try to access the server using apache I get a "500 - Internal server error".

The error file from apache:

[Fri Apr 27 22:52:01 2012] [notice] caught SIGTERM, shutting down

Anyone familiar with this error - and feels like helping me our?

As far as I understood this errorlinge is key to figuring out the issue, but googeling and did not help me much.

<internal:lib/rubygems/custom_require>:29:in `require': no such file to load -- phusion_passenger/utils (LoadError)

Edit: I found out my first error was that I wrote "bun" and not "bin" in the mods-enables file in apache. And thus not pointing it to a correct-ruby directory.

I now get an error generated by passenger. Saying the following:

Ruby (Rack) application could not be started
Error message:
    no such file to load -- bundler

And then it goes on with a long backtrace, i will post a short snippitt here:

Solution

  • I had the same issue, then I fixed it by installing passenger via gems.

    Visit the Phusion Passenger (mod_rails) website for complete documentation on Passenger. You will need GCC installed to setup passenger.

    Install Passenger via Gem

    gem install passenger

    Run the passenger install script for apache2

    passenger-install-apache2-module

    Put the following in /etc/httpd/conf.d/passenger.conf (better to copy direct from the passenger-install-apache2-module output)

    LoadModule passenger_module /usr/lib/ruby/gems/1.8/gems/passenger-2.2.3/ext/apache2    /mod_passenger.so
PassengerRoot /usr/lib/ruby/gems/1.8/gems/passenger-2.2.3
PassengerRuby /usr/bin/ruby
