Proxies with Apache and python
2014/10/09
python
apache
proxy
gunicorn
uwsgi
This is a quick note on proxying a local python application (e.g. flask)
to a subdirectory in Apache. This assumes that the file wsgi.py contains
a WSGI application with the name application. Hence, wsgi:application.
Gunicorn

<Location /myapp/>
ProxyPass http://127.0.0.1:8888/myapp/
ProxyPassReverse http://127.0.0.1:8888/myapp/
RequestHeader set SCRIPT_NAME "/myapp/"
</Location>
|
Important: SCRIPT_NAME and the end of ProxyPass URL MUST BE
THE SAME. Otherwise, Gunicorn will fail miserably.
Try it with:
1
|
venv/bin/gunicorn -w 4 -b 127.0.0.1:8888 --log-file - --access-logfile - wsgi:application
|
UWSGI
This is a very simple configuration. I will try to upload one with more
options for uwsgi (in a .ini file).

<Location /myapp/>
SetHandler uwsgi_handler
uWSGISocker 127.0.0.1:8888
</Location>

Try it with:
1
|
uwsgi --socket 127.0.0.1:8888 -w wsgi:application

If everything went as expected, you can wrap your command in a
supervisor config file and let it handle the server for you.
