Answer 1

Steps for upgrading Rails 2.2.2 to 2.3.11.

1. rails install -v=2.3.11

2. modify config/environment.rb

   RAILS_GEM_VERSION = '2.3.11' unless defined? RAILS_GEM_VERSION
   

3. run rake task => rake rails:update # Update configs, scripts and javascripts

   This rake task will modify some of the files.

4. modify config/environment.rb

   Replace

   config.action_controller.session = {
     :session_key => '_name_session',
     :secret      => 'asdfasfasfafafafadaseerweewr'
   }
   

   with

   config.action_controller.session = {
     :key => '_name_session',
     :secret      => 'asdfasfasfafafafadaseerweewr'
   } 
   

5. modify app/controllers/application_controller.rb

   Replace

   session :session_key => '_intrado_session_id'
   

   with

   #session :session_key => '_intrado_session_id'
   

6. Replace

   session.session_id
   

   with

   request.session_options[:id]
   

May be this will help...

EDIT:

Rails 2.3.11 + Rack 1.0.0 + Phusion Passenger 2.0.6 causing problem 500 internal server error undefined method 'rewind' to solve that issue.

I have installed.

1. sudo gem install rack -v=1.1.1

2. sudo gem install passenger -v=2.2.8

3. passenger-install-apache2-module

It would prompt you to replace few lines in /etc/httpd/conf/httpd.conf with the following at the end of installation of the 3nd step

LoadModule passenger_module /usr/local/lib/ruby/gems/1.8/gems/passenger-2.2.8/ext/apache2/mod_passenger.so
PassengerRoot /usr/local/lib/ruby/gems/1.8/gems/passenger-2.2.8
PassengerRuby /usr/local/bin/ruby

This file would already have above three lines. So, it would be sufficient to replace 2.0.6 with 2.2.8.

After performing the above steps, restart apache2 and restart rails by the following commands.

1. sudo /etc/init.d/http.d restart
2. cd /var/www/project_name
3. sudo touch tmp/restart.txt
