Redmine

Hello,
I have followed the installation instructions, logged as root, from http://www.redmine.org/projects/redmine/wiki/RedmineInstall
with

RHEL5
rvm and ruby 1.9.3p327
Rails 3.2.9
Phusion Passenger version 3.0.18
redmine checkout v 2.1.4

I succeeded to run redmine, with webrick, using ruby script/rails server webrick -e production and to access it from my LAN with
http://192.xxx.xxx.xxx:3000/

I must admit that i do not see exactly how all these ruby/rails/passenger and redmine work together, and i did not manage to run redmine from apache2, which is currently running, providing some other services.

I want redmine to be accessible from a LAN, and to use a 'sub-URI' approach:

• I created a softlink : /var/www/html/redmine -> /opt/redmine/public
• I added the following in my /etc/httpd/conf/httpd.conf :
  

  Listen *:3000
  
  LoadModule passenger_module /usr/local/rvm/gems/ruby-1.9.3-p327/gems/passenger-3.0.18/ext/apache2/mod_passenger.so
  PassengerRoot /usr/local/rvm/gems/ruby-1.9.3-p327/gems/passenger-3.0.18
  PassengerRuby /usr/local/rvm/wrappers/ruby-1.9.3-p327/ruby
  PassengerUserSwitching off
  PassengerDefaultUser apache
  
  <Directory /var/www/html/redmine>
      RailsBaseURI /redmine
      PassengerResolveSymlinksInDocumentRoot on
      Options -MultiViews
  </Directory>
  

• Of course, i use service httpd restart every time i modify something.

I am not sure this configuration is sufficient, and i was wondering if adding the passenger_module to the httpd.conf implied that redmine started with apache service, or if redmine had to be launched another way...?

In the logfile (/var/log/httpd/error_log), i found something interesting occuring when restarting httpd service :

[Wed Dec 05 10:33:46 2012] [notice] Apache/2.2.3 (Red Hat) configured -- resuming normal operations
/usr/local/rvm/rubies/ruby-1.9.3-p327/lib/ruby/site_ruby/1.9.1/rubygems/specification.rb:541:in `read': Permission denied - /usr/local/rvm/gems/ruby-1.9.3-p327/specifications/rails-3.2.8.gemspec (Errno::EACCES)

I realize that i have both rails-3.2.8.gemspec and rails-3.2.9.gemspec, and that the one apache (or passenger or rails, or ruby ... :s) is looking for, is actually one with no read permission for apache user.

-rw-r----- 1 root rvm 2069 Dec  4 09:15 rails-3.2.8.gemspec
-rw-rw-r-- 1 root rvm 2069 Dec  4 08:59 rails-3.2.9.gemspec

Why is it trying to read rails-3.2.8.gemspec instead of rails-3.2.9.gemspec, since "rails -v" returns me "Rails 3.2.9" ?

I hope there is enough informations here, and i would enjoy any help into this setup process !
Thanks,
