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 Werkzeug application on Google’s AppEngine, there however the execution does happen in a CGI-like environment. The application’s performance is unaffected because of that.
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 make_app application = make_app() CGIHandler().run(application)
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 something like this into the config:
ScriptAlias /app /path/to/the/application.cgi
For more information consult the documentation of your webserver.
