Options may include:
:app
a rack application to run (overrides :config)
:config
a rackup configuration file path to load (.ru)
:environment
this selects the middleware that will be wrapped around your application. Default options available are: - development: CommonLogger, ShowExceptions, and Lint - deployment: CommonLogger - none: no extra middleware note: when the server is a cgi server, CommonLogger is not included.
:server
choose a specific Rack::Handler, e.g. cgi, fcgi, webrick
:daemonize
if true, the server will daemonize itself (fork, detach, etc)
:pid
path to write a pid file after daemonize
:Host
the host address to bind to (used by supporting Rack::Handler)
:Port
the port to bind to (used by supporting Rack::Handler)
:AccessLog
webrick acess log options (or supporting Rack::Handler)
:debug
turn on debug output ($DEBUG = true)
:warn
turn on warnings ($-w = true)
:include
add given paths to $LOAD_PATH
:require
require the given libraries

Start a new rack server (like running rackup). This will parse ARGV and provide standard ARGV rackup options, defaulting to load ‘config.ru’.
Providing an options hash will prevent ARGV parsing and will not include any default options.
This method can be used to very easily launch a CGI application, for example:
Rack::Server.start( :app => lambda do |e| [200, {'Content-Type' => 'text/html'}, ['hello world']] end, :server => 'cgi' )
Further options available here are documented on Rack::Server#initialize
