CGI |
|
=== |
|
|
|
If all other deployment methods do not work, CGI will work for sure. CGI |
|
is supported by all major servers but usually has a less-than-optimal |
|
performance. |
|
|
|
This is also the way you can use a Flask application on Google's |
|
`App Engine`_, there however the execution does happen in a CGI-like |
|
environment. The application's performance is unaffected because of that. |
|
|
|
.. admonition:: Watch Out |
|
|
|
Please make sure in advance that your ``app.run()`` call you might |
|
have in your application file, is inside an ``if __name__ == |
|
'__main__':`` or moved to a separate file. Just make sure it's not |
|
called because this will always start a local WSGI server which we do |
|
not want if we deploy that application to CGI / app engine. |
|
|
|
.. _App Engine: http://code.google.com/appengine/ |
|
|
|
Creating a `.cgi` file |
|
---------------------- |
|
|
|
First you need to create the CGI application file. Let's call it |
|
`yourapplication.cgi`:: |
|
|
|
#!/usr/bin/python |
|
from wsgiref.handlers import CGIHandler |
|
from yourapplication import app |
|
|
|
CGIHandler().run(app) |
|
|
|
Server Setup |
|
------------ |
|
|
|
Usually there are two ways to configure the server. Either just copy the |
|
`.cgi` into a `cgi-bin` (and use `mod_rewrite` or something similar to |
|
rewrite the URL) or let the server point to the file directly. |
|
|
|
In Apache for example you can put a like like this into the config: |
|
|
|
.. sourcecode:: apache |
|
|
|
ScriptAlias /app /path/to/the/application.cgi |
|
|
|
For more information consult the documentation of your webserver.
