| post | Proxies with Apache and python | 2014-10-09 10:00:00 | 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/" {% 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 {% 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 %}
