So what is WSGI anyway?

WSGI (pronounced Whisky) is the Web Server Gateway Interface. It is a specification for web servers and application servers to communicate with web applications (though it can also be used for more than that). It is a Python standard, described in detail in PEP 333.

modwsgi

modwsgi is an Apache module which can host any Python application which supports the Python WSGI interface. The module is suitable for use in hosting high performance production web sites, as well as average personal sites running on commodity web hosting services.

To install: yum install mod_wsgi

Example Settings for MoinMoin

httpd.conf

WSGISocketPrefix run/wsgi

# new wsgi moin stuff
# this is for icons, css, js (and must match url_prefix from wiki config):
Alias /moinmoin/ls_stardust/ /home/david/www/ls_stardust/

# this is the URL http://servername/moin/ you will use later to invoke moin:
WSGIScriptAlias /wiki /home/david/lib/moinmoin/moin.wsgi

# create some wsgi daemons - use someuser.somegroup same as your data_dir:

WSGIDaemonProcess wikidaemon user=david group=david processes=5 threads=10 maximum-requests=1000 umask=0007
# umask=0007 does not work for mod_wsgi 1.0rc1, but will work later

# use the daemons we defined above to process requests!
WSGIProcessGroup wikidaemon

moin.wsgi

import logging

from MoinMoin.server.server_wsgi import WsgiConfig, moinmoinApp

class Config(WsgiConfig):
    logPath = '/home/david/data/moinmoin/moin.log' # adapt this to your needs!
    #loglevel_file = logging.INFO # adapt if you don't like the default

config = Config() # MUST create an instance to init logging!

application = moinmoinApp

flup

flup includes three sets of WSGI servers/gateways, which speak AJP 1.3, FastCGI, and SCGI. Each server comes in two flavors: a threaded version, and a forking version.

WebDev | Apache | FastCGI | mod_python | CGI | flup
