How to run Ruby on Rails?

[John]

If you have an existing application, Change the line in your Rails application’s public/dispatch.fcgi.

Change

require 'fcgi'

To

require 'fcgi'
require 'rubygems'
require_gem 'fcgi'

Make sure Apache can find dispatch.fcgi

Now edit your app’s public/.htaccess and change/add the following lines to make sure that the Rails app is using FastCGI and that it knows that the app is living in a subdirectory.

Change:

RewriteRule ^(.*)$ dispatch.cgi?$1 [QSA,L]

To:

RewriteBase /testapp
RewriteRule ^(.*)$ dispatch.fcgi?$1 [QSA,L]

Make sure that dispatch.fcgi is executable:

$ chmod 755 public/dispatch.fcgi
