Download the latest ruby-web_x.x.x.tar.gz. Run the enclosed installer:

% cd ruby-web_x.x.x
% ruby install.rb config
% ruby install.rb setup
% ruby install.rb install

This will compile and install the ruby-web interpreter into the same directory as ruby. If you are running ruby-web as a cgi, all you need to do is swap ruby-web for ruby:

#!/usr/bin/ruby-web

puts 'Hello, World'

FastCGI

After configuring ruby-web as the interpreter, you need the library to run fastcgi.

You will still need to do the standard FastCGI config on your webserver. You can find a links to extensions for Apache and other web servers at http://www.fastcgi.com

Mod Ruby

To use the ruby-web interpreter with mod_ruby, there is a slightly different configuration for http.conf:

  <IfModule mod_ruby.c>
  RubySafeLevel 0
  # for Web::RubyRun
  RubyRequire web/sapi/apache

  <Location / >
      Options Indexes FollowSymLinks ExecCGI
      AddHandler ruby-object cgi rb rhtml
      RubyHandler Web::RubyRun.instance
  </Location>
  </IfModule>
  

Webrick

ruby-web provides a Web::RubyWebHandler, based on the CGIHandler, to run ruby-web scripts. You will need to add the Web::RubyWebHandler to webrick with a startup script like this, replacing :DocumentRoot with the appropriate value:

    #!/usr/local/bin/ruby
    $: << File.dirname($0)
    require 'webrick'
    require 'web/sapi/webrick'

    include WEBrick

		# These lines configure webrick to handle .rb and .rhtml files with ruby-web
    HTTPServlet::FileHandler.add_handler("rb", Web::RubyWebHandler)
    HTTPServlet::FileHandler.add_handler("rhtml", Web::RubyWebHandler)

    s = HTTPServer.new(:Port            => 80,
                       :DocumentRoot    => "./htdocs" )
    trap("INT"){ s.shutdown }
    s.start
