1 つのサーバで複数バージョンの Rails 動かすにはどうしたらいいでしょうか？
この場合、メインで動かす mod_rails 環境に加えて Apache, nginx, Phusion Passenger でリバースプロキシを構成することになります。

====

現在インストールされている Ruby のバージョンの確認

$ ruby -v
ruby 1.9.2p290 (2011-07-09 revision 32553) [x86_64-linux]

Ruby 1.8.7 をインストールする

# rvm install 1.8.7
# rvm use 1.8.7
# ruby -v
ruby 1.8.7 (2011-06-30 patchlevel 352) [x86_64-linux]

global gemset に Passenger をインストールする

# rvm gemset use global
# gem install passenger --pre

Rails をインストールする

# rvm gemset create rails-2.3.11
# rvm gemset use rails-2.3.11
# gem install rails -v '2.3.11'

.rvmrc の作成

$ cd /path/to/rails_app
$ rvm --rvmrc --create 1.8.7@rails-2.3.11
# rvm rvmrc trust /path/to/rails_app/

Apache のリバースプロキシ設定

<VirtualHost *:80>
    DocumentRoot /path/to/rails_app/public
    ServerName xchannel.info
    PassengerEnabled off
    ProxyPass / http://127.0.0.1:3000/
    ProxyPassReverse / http://127.0.0.1:3000/
</VirtualHost>

httpd を再起動します。

# service httpd restart

Rails の細かい設定

config/setup_load_paths.rb というファイルを作成して小細工をします。

#config/setup_load_paths.rb
if ENV['MY_RUBY_HOME'] && ENV['MY_RUBY_HOME'].include?('rvm')
  begin
    rvm_path     = File.dirname(File.dirname(ENV['MY_RUBY_HOME']))
    rvm_lib_path = File.join(rvm_path, 'lib')
    $LOAD_PATH.unshift rvm_lib_path
    require 'rvm'
    RVM.use_from_path! File.dirname(File.dirname(__FILE__))
  rescue LoadError
    # RVM is unavailable at this point.
    raise "RVM ruby lib is currently unavailable."
  end
end

nginx のインストール & Passenger を standalone で起動

$ passenger start -a 127.0.0.1 -p 3000 -d

むむむ、エラー・・・。もう一回。

$ passenger start -a 127.0.0.1 -p 3000 -d
Nginx core 0.7.67 isn't installed

Phusion Passenger Standalone will automatically install it into:

  /home/noguchi/.passenger/standalone/3.0.0.pre4-x86_64-ruby1.8.7-linux-gcc4.1.2-1002/nginx-0.7.67

This will only be done once. Please sit back and relax while installation is
in progress.

Looks like it's not. But don't worry, the necessary binaries will be compiled from source instead.

今度はうまく nginx がインストールされ、Passenger が standalone で起動されました。
ちなみに tips なのですが、Passenger を起動するときに -e production とすると production モードで起動することができます。
