<a href="Server/Options.html">Options</a> may include:
</p>
<ul>
<li>:<a href="Server.html#M000420">app</a>
<pre>
a rack application to run (overrides :config)
</pre>
</li>
<li>:config
<pre>
a rackup configuration file path to load (.ru)
</pre>
</li>
<li>:environment
<pre>
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.
</pre>
</li>
<li>:<a href="Server.html#M000426">server</a>
<pre>
choose a specific Rack::Handler, e.g. cgi, fcgi, webrick
</pre>
</li>
<li>:daemonize
<pre>
if true, the server will daemonize itself (fork, detach, etc)
</pre>
</li>
<li>:pid
<pre>
path to write a pid file after daemonize
</pre>
</li>
<li>:Host
<pre>
the host address to bind to (used by supporting Rack::Handler)
</pre>
</li>
<li>:Port
<pre>
the port to bind to (used by supporting Rack::Handler)
</pre>
</li>
<li>:AccessLog
<pre>
webrick access log options (or supporting Rack::Handler)
</pre>
</li>
<li>:debug
<pre>
turn on debug output ($DEBUG = true)
</pre>
</li>
<li>:warn
<pre>
turn on warnings ($-w = true)
</pre>
</li>
<li>:include
<pre>
add given paths to $LOAD_PATH
</pre>
</li>
<li>:require
<pre>
require the given libraries

<p>
Start a <a href="Server.html#M000417">new</a> rack <a
href="Server.html#M000426">server</a> (like running rackup). This will
parse ARGV and provide standard ARGV rackup <a
href="Server.html#M000418">options</a>, defaulting to load
‘config.ru’.
</p>
<p>
Providing an <a href="Server.html#M000418">options</a> hash will prevent
ARGV parsing and will not include any default <a
href="Server.html#M000418">options</a>.
</p>
<p>
This method can be used to very easily launch a CGI application, for
example:
</p>
<pre>
Rack::Server.start(
:app => lambda do |e|
[200, {'Content-Type' => 'text/html'}, ['hello world']]
end,
:server => 'cgi'
)
</pre>
<p>
Further <a href="Server.html#M000418">options</a> available here are
documented on Rack::Server#initialize
