Webpy + Apache with mod_wsgi

The following steps were tested on Apache-2.2.3 (Red Hat Enterprise Linux 5.2, x86_64), mod_wsgi-2.0.

Note:

  • You may replace ‘appname’ with your own project name.
  • You may replace code.py with your own file name.
  • /var/www/webpy-app found below refers to the path to the directory contains your code.py
  • /var/www/webpy-app/code.py is the full path to your python file

Steps:

  • Download and install mod_wsgi from its website: http://code.google.com/p/modwsgi/. It will install a ‘.so’ module in Apache module directory. e.g.

      /usr/lib64/httpd/modules/
    
  • Configure Apache to load mod_wsgi module and your project in httpd.conf:

      LoadModule wsgi_module modules/mod_wsgi.so
    
      WSGIScriptAlias /appname /var/www/webpy-app/code.py/
    
      Alias /appname/static /var/www/webpy-app/static/
      AddType text/html .py
    
      <Directory /var/www/webpy-app/>
          Order deny,allow
          Allow from all
      </Directory>
    
  • Sample file ‘code.py’:

      import web
    
      urls = (
          '/.*', 'hello',
          )
    
      class hello:
          def GET(self):
              return "Hello, world."
    
      application = web.application(urls, globals()).wsgifunc()
    
  • Point your browser to ‘http://your_server_name/appname’ to verify whether it works for you.

#Note: mod_wsgi + sessions

If you use sessions with mod_wsgi, you should change you code like below:

app = web.application(urls, globals())

curdir = os.path.dirname(__file__)
session = web.session.Session(app, web.session.DiskStore(os.path.join(curdir,'sessions')),)

application = app.wsgifunc()
