This must be a simple question, but I could not find the answer by browsing this forum.

When I check rails version, it shows version 3.2.8

user@domain.com [~/rails_apps]# rails -v
Rails 3.2.8
user@domain.com [~/rails_apps]#

But when I start the server, it runs version 2.3.11

user@domain.com [~/rails_apps/myapp]# script/server -p12011
=> Booting Mongrel
=> Rails 2.3.11 application starting on http://0.0.0.0:12011
/home3/user/rails_apps/myapp/config/environment.rb:45: warning: already initialized constant RAILS_ENV
NOTE: SourceIndex.new(hash) is deprecated; From /usr/lib64/ruby/gems/1.8/gems/rails-2.3.11/lib/rails/vendor_gem_source_index.rb:100:in `new'.
=> Call with -d to detach
=> Ctrl-C to shutdown server

What am I doing wrong?

    If you application is a 2.x rails application, you need to complete some changes before upgrade to 3.x

    You may have a look to railscast http://railscasts.com/?tag_id=27

    On the other hand, you may want to upgrade your ruby to 1.9 using rvm
    rails 3.x work better with ruby 1.9
