+tags: 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
+{% highlight apache %}
+<Location /myapp/>
+    ProxyPass http://127.0.0.1:8888/myapp/
+    ProxyPassReverse http://127.0.0.1:8888/myapp/
+    RequestHeader set SCRIPT_NAME "/myapp/"
+</Location>
+{% endhighlight %}
+
+**Important**: *SCRIPT_NAME* and the end of *ProxyPass* URL  **MUST BE THE SAME**. Otherwise, Gunicorn will fail miserably.
+
+Try it with:
+{% highlight bash %}
+venv/bin/gunicorn -w 4 -b 127.0.0.1:8888 --log-file - --access-logfile - wsgi:application
+{% endhighlight %}
+
+
+## UWSGI 
+This is a very simple configuration. I will try to upload one with more options for uwsgi (in a .ini file).
+
+{% highlight apache %}
+<Location /myapp/>
+    SetHandler uwsgi_handler
+    uWSGISocker 127.0.0.1:8888
+</Location>
+{% endhighlight %}
+
+Try it with:
+
+{% highlight bash %}
+uwsgi --socket 127.0.0.1:8888 -w wsgi:application
+{% endhighlight %}
+
+### Extra: Supervisor
+If everything went as expected, you can wrap your command in a supervisor config file and let it handle the server for you.
+{% highlight ini %}
+[unix_http_server]
+file=/tmp/myapp.sock                       ; path to your socket file
+
+[supervisord]
+logfile = %(here)s/logs/supervisor.log
+childlogdir = %(here)s/logs/
+
+[rpcinterface:supervisor]
+supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface
+
+[supervisorctl]
+logfile = %(here)s/logs/supervisorctl.log
+serverurl=unix:///tmp/supervisor.sock         ; use a unix:// URL  for a unix socket
+
+
+[program:myapp]
+command = venv/bin/gunicorn -w 4 -b 0.0.0.0:5000 --log-file %(here)s/logs/gunicorn.log --access-logfile - wsgi:application
+directory = %(here)s
+environment = PATH=%(here)s/venv/bin/
+logfile = %(here)s/logs/myapp.log
+{% endhighlight %}
