Starting in CherryPy 3.1, cherrypy.server is implemented as an :ref:`Engine Plugin<plugins>`. It's an instance of :class:`cherrypy._cpserver.Server`, which is a subclass of :class:`cherrypy.process.servers.ServerAdapter`. The ``ServerAdapter`` class is designed to control other servers, as well.
If you need to start more than one HTTP server (to serve on multiple ports, or protocols, etc.), you can manually register each one and then start them all with engine.start:
s1 = ServerAdapter(cherrypy.engine, MyWSGIServer(host='0.0.0.0', port=80)) s2 = ServerAdapter(cherrypy.engine, another.HTTPServer(host='127.0.0.1', SSL=True)) s1.subscribe() s2.subscribe() cherrypy.engine.start()
.. index:: SCGI
There are also Flup\ **F**\ CGIServer and Flup\ **S**\ CGIServer classes in :mod:`cherrypy.process.servers`. To start an fcgi server, for example, wrap an instance of it in a ServerAdapter:
addr = ('0.0.0.0', 4000) f = servers.FlupFCGIServer(application=cherrypy.tree, bindAddress=addr) s = servers.ServerAdapter(cherrypy.engine, httpserver=f, bind_addr=addr) s.subscribe()
The :doc:`cherryd</deployguide/cherryd>` startup script will do the above for you via its `-f` flag. Note that you need to download and install `flup <http://trac.saddi.com/flup>`_ yourself, whether you use ``cherryd`` or not.
.. _fastcgi: .. index:: FastCGI
A very simple setup lets your cherry run with FastCGI. You just need the flup library, plus a running Apache server (with ``mod_fastcgi``) or lighttpd server.
CherryPy code ^^^^^^^^^^^^^
hello.py:
#!/usr/bin/python import cherrypy class HelloWorld: """Sample request handler class.""" def index(self): return "Hello world!" index.exposed = True cherrypy.tree.mount(HelloWorld()) # CherryPy autoreload must be disabled for the flup server to work cherrypy.config.update({'engine.autoreload.on':False})
Then run :doc:`/deployguide/cherryd` with the '-f' arg:
cherryd -c <myconfig> -d -f -i hello.py
Apache ^^^^^^
At the top level in httpd.conf:
FastCgiIpcDir /tmp FastCgiServer /path/to/cherry.fcgi -idle-timeout 120 -processes 4
And inside the relevant VirtualHost section:
# FastCGI config AddHandler fastcgi-script .fcgi ScriptAliasMatch (.*$) /path/to/cherry.fcgi$1
Lighttpd ^^^^^^^^
For `Lighttpd <http://www.lighttpd.net/>`_ you can follow these instructions. Within ``lighttpd.conf`` make sure ``mod_fastcgi`` is active within ``server.modules``. Then, within your ``$HTTP["host"]`` directive, configure your fastcgi script like the following:
$HTTP["url"] =~ "" { fastcgi.server = ( "/" => ( "script.fcgi" => ( "bin-path" => "/path/to/your/script.fcgi", "socket" => "/tmp/script.sock", "check-local" => "disable", "disable-time" => 1, "min-procs" => 1, "max-procs" => 1, # adjust as needed ), ), ) } # end of $HTTP["url"] =~ "^/"
Please see `Lighttpd FastCGI Docs <http://redmine.lighttpd.net/wiki/lighttpd/Docs:ModFastCGI>`_ for an explanation of the possible configuration options.
