CGI deployment on Apache

Here are the simple steps needed to create and run an web.py application.

  • Install web.py and flups

  • Create the application as documented

      if __name__ == "__main__":
          web.run(urls, globals())

For our example, let it be named app.py, located in /www/app and we need it accessible as http://server/app/app.py.

  • Configure Apache (version 2.2 in this example)

      ScriptAlias /app "/www/app/"
      <Directory "/www/app/">
              Options +ExecCGI +FollowSymLinks
              Order allow,deny
              Allow from all

That’s it. Your application is accessible via http://server/app/app.py/. Additional URLs handled by the application are added to the end of the URL, for examples http://server/app/app.py/myurl.

  • .htaccess configuration

            Options +ExecCGI
            AddHandler cgi-script .py
            DirectoryIndex index.py
            <IfModule mod_rewrite.c>
                RewriteEngine on
                RewriteBase /
                RewriteCond %{REQUEST_FILENAME} !-f
                RewriteCond %{REQUEST_FILENAME} !-d
                RewriteCond %{REQUEST_URI} !^/favicon.ico$
                RewriteCond %{REQUEST_URI} !^(/.*)+index.py/
                RewriteRule ^(.*)$ index.py/$1 [PT]

Here it is assumed that your application is called index.py. The above htaccess checks if some static file/directory exists failing which it routes the data to your index.py. Change the Rewrite Base to a sub-directory if needed.
