+title: Proxies with Apache and python
+date:   2014-10-09 10:00:00
+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
+--------
+
+```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>
+```
+
+<!--more-->
+
+**Important**: *SCRIPT_NAME* and the end of *ProxyPass* URL **MUST BE
+THE SAME**. Otherwise, Gunicorn will fail miserably.
+
+Try it with:
+
+```bash
+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).
+
+```apache
+<Location /myapp/>
+    SetHandler uwsgi_handler
+    uWSGISocker 127.0.0.1:8888
+</Location>
+```
+
+Try it with:
+
+```bash
+uwsgi --socket 127.0.0.1:8888 -w wsgi:application
+```
+
+### 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.
+
+```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
+```
