Django: channels 2.0 with nginx + daphne

Recently I made chat function with django channels 2.0

It’s bit easy to create function in local, but I encountered obstacle while deploy it to production server.

I have to use asgi for deploy socket. For that, I use daphne instead of gunicorn or uwsgi.

Install redis in ubuntu

First, just redis. It’s not a hard work.

sudo apt-get install redis-server

# then start server
redis-server start

# can access redis-cli
redis-cli

Install channel_redis

Have to install dependencies just like local’s requirements.txt

pip install -U channels_redis

Add asgi.py

Have to make asgi.py just beside wsgi.py

"""
ASGI entrypoint. Configures Django and then runs the application
defined in the ASGI_APPLICATION setting.
"""

import os
import django
from channels.routing import get_default_application

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "myproject.settings")
django.setup()
application = get_default_application()

use daphne

daphne myproject.asgi:application

        }
    }
    # your settings include /static or /media
    ...
