rackup [ruby options] [rack options] [rackup config]

Rackup is a useful tool for running Rack applications, which uses the Rack::Builder DSL to configure middleware and build up applications easily.

rackup automatically figures out the environment it is run in, and runs your application as FastCGI, CGI, or standalone with Mongrel or WEBrick -all from the same configuration.

Ruby options:

-e, --eval [LINE]

evaluate a LINE of code

-d, --debug

set debugging flags (set $DEBUG to true)

-w, --warn

turn warnings on for your script

-I, --include [PATH]

specify $LOAD_PATH (may be used more than once)

-r, --require [LIBRARY]

require the library, before executing your script

Rack options:

-s, --server [SERVER]

serve using SERVER (webrick/mongrel)

-o, --host [HOST]

listen on HOST (default: 0.0.0.0)

-p, --port [PORT]

use PORT (default: 9292)

-E, --env [ENVIRONMENT]

use ENVIRONMENT for defaults (default: development)

-D, --daemonize

run daemonized in the background

-P, --pid [FILE]

file to store PID (default: rack.pid)

Common options:

-h, --help

Show the help message

--version

Show version

This is a simple example on how to start an application based on Rack with rackup:

$ rackup -Ilib blog/config.ru
