django-wsgiserver Description
A web server for Django using CherryPy's WSGI server django-wsgiserver is a Django plugin for serving Django sites via CherryPy's excellent, production ready, pure-python web server without needing to install all of Cherrypy. Note that Cherrypy names its server "wsgiserver" but it is actually a full-blown, multi-threaded http/https web server which has been used on production sites alone, or more often proxied behind a something like Apache or nginx.UsesThe wsgiserver component has been used for years in production. Peter Baumgartner noted that it solved problems for him on memory on a memory-limited VPS hosted site . Performance-wise it does well: it can serve up thousands of requests per second .I haven't used django-wsgiserver for production myself (yet) as daemonized modwsgi and uwsgi have served me well. I use it all the time though during development. It's my "pocket-sized" server. completely written in python and it gives me an instant approximation of the final production environment I use. In some ways, it's much better than the development server which is built into django. It's noticeable when I have pages that do multiple ajax calls and the built-in runserver hangs. I just stop the built-in server, and then domanage.py runwsgiserverand reload my browser page and the problem is fixed. It's also useful to see if some weird effect is being caused by runserver's process of loading the settings twice.This project is a slight modification of code form Peter Baumgartner code (see Peter's blog post) Peter and others did the work of creating a management command. I've added a few small improvements from my point of view: It doesn't require installing cherrypy separately. It uses the same port as the development server (8000) so I don't need to re-enter my testing url in my browser, and it works by default with OS's like Mac OS 10.6 and Ubuntu 10.04 which prefer binding localhost to an ip6 address.RequirementsTo get started using the server, you need nothing outside of django itself and the project code that you would like to serve up. However, for ssl support, you may need PyOpenSSL--though the new cherrypy server includes support for using the python built-in ssl module depending on which version of python you are using.InstallationTo install, django-wsgiserver follows the usual pattern for a django python application. You have several options 1. pip install django-wsgiserver OR 2. easy_install django-wsgiserver 3. If you would like to use the latest possible version, you can use pip and mercurial checkout from bitbucketpip install -e hg+https://cleemesser@bitbucket.org/cleemesser/django-cherrypy-wsgiserver#egg=django-wsgiserver 4. Alternatively you can download the code and install it so that django_wsgiserver is on your PYTHONPATHAfter you used one of the methods above, you need to add django_wsgiserver to your INSTALLED_APPS in your django project's settings file.UsageTo see how to run the server as a management command, run:python manage.py runwsgiserver helpfrom within your project directory. You'll see something like what's below:Run this project in CherryPy's production quality http webserver.Note that it's called wsgiserver but it is actually a complete http server. runwsgiserver Optional CherryPy server settings: (setting=value) host=HOSTNAME hostname to listen on Defaults to 127.0.0.1, (set to 0.0.0.0 to bind all ip4 interfaces or :: for all ip6 interfaces) port=PORTNUM port to listen on Defaults to 8000 server_name=STRING CherryPy's SERVER_NAME environ entry Defaults to localhost daemonize=BOOL whether to detach from terminal Defaults to False pidfile=FILE write the spawned process-id to this file workdir=DIRECTORY change to this directory when daemonizing threads=NUMBER Number of threads for server to use ssl_certificate=FILE SSL certificate file ssl_private_key=FILE SSL private key file server_user=STRING user to run daemonized process Defaults to www-data server_group=STRING group to daemonized process Defaults to www-data Examples: Run a "standard" CherryPy server server $ manage.py runwsgiserver Run a CherryPy server on port 80 $ manage.py runwsgiserver port=80Run a CherryPy server as a daemon and write the spawned PID in a file $ manage.py runwsgiserver daemonize=true pidfile=/var/run/django-cpwsgi.pid Run a CherryPy server using ssl with test certificates located in /tmp $ manage.py runwsgiserver ssl_certificate=/tmp/testserver.crt ssl_private_key=/tmp/testserver.keyNotesIf you want to use an installed version of Cherrypy--perhaps because you now have a more recent version, you only need to change one line of code in (around line 177) of django_wsgiserver/management/commands/run_wsgiserver.py:from django_wsgiserver.wsgiserver import CherryPyWSGIServer as Server#from cherrypy.wsgiserver import CherryPyWSGIServer as ServerJust comment out the import from django_wsgiserver.wsgiserver and uncomment the import from cherrypy.wsgiserver to make the switch. Requirements: · Python · Django What's New in This Release: · added test project in tests/ directory · got tired of typing run_cp_wsgiserver so did a rename so I could use runwsgiserver instead. · updated wsgiserver to svn r2680 (matches cherrypy version 3.2 beta+). This fixes some bugs and gives better python 2.6 support. This version of cherrypy will also support python 3.x for whenever django starts supporting it. · use port 8000 as with django devserver rather than Cherrypy's default 8088 · adapted defaults host=127.0.0.1 in order to work with ip4 by default. This addresses an issue I first noticed on mac OS 10.6 and later on ubuntu 10.04 where ip6 is active by default. Can get around this by adjusting the host option. For binding all ip4 interfaces, set to 0.0.0.0. For all ip6 interfaces I believe you use '::' You can also bind a specific interface by specifying host= See http://www.cherrypy.org/ticket/711 · switched code to use run_cp_wsgiserver instead of runcpserver
