rvmでrubyとrailsをセット
まずはrvmを更新しておく。
[root@localhost ~]# rvm get stable
今回必要なバージョンはそれぞれ以下。
ruby 1.8.7 (2009-12-24 patchlevel 248) [x86_64-linux], MBARI 0x6770, Ruby Enterprise Edition 2010.01
Rails 2.3.5
1.8.7をインストールしgemset（受け皿）を作成
[root@localhost ~]# rvm install 1.8.7
Warning! PATH is not properly set up, '/usr/local/rvm/gems/ruby-1.9.3-p374/bin' is not at first place,
usually this is caused by shell initialization files - check them for 'PATH=...' entries,
it might also help to re-add RVM to your dotfiles: 'rvm get stable --auto-dotfiles',
to fix temporarily in this shell session run: 'rvm use ruby-1.9.3-p374'.
Searching for binary rubies, this might take some time.
No binary rubies available for: centos/6/x86_64/ruby-1.8.7-p374.
It is not possible to build movable binaries for rubies 1.8-1.9.2, but you can do it for your system only.
Continuing with compilation. Please read 'rvm help mount' to get more information on binary rubies.
Checking requirements for centos.
Installing requirements for centos.
Updating system.

WARNING: Please be aware that you just installed a ruby that is no longer maintained, for a list of maintained rubies visit:
http://bugs.ruby-lang.org/projects/ruby/wiki/ReleaseEngineering
Please consider upgrading to ruby-2.1.0 which will have all of the latest security patches.
Ruby was built without documentation, to build it run: rvm docs generate-ri
[root@localhost ~]# rvm gemset create rails235

[root@localhost ~]# rvm 1.8.7@rails235
作ったgemsetでrailsをインストール。
# gem install rails --version "=2.3.5"
同一バージョンのrubyで複数のgemsetを作成して管理することもできるらしい。 参考にしたのはこちら。 http://serihiro.hatenablog.com/entry/20130421/1366552174
マシンを分けたほうがいいと思うけど、必要な場合もあるだろうということで。
