SOLVED - How to configure Daphne proxy with Nginx and uwsgi

Question

I have a Django application located in a server with Nginx and uwsgi configuration. And now I have to work with Django Channels too. In a local computer all it's fine but I have read a lot about that Django Channels is not compatible with uwsgi.

I tried to configure many times and many different ways a proxy in nginx.conf with Daphne but nothing works for me. I have this problem for several months and I can't find anything that can help me.

settings.py

# WSGI
WSGI_APPLICATION = 'config.wsgi.application'

# Channels
ASGI_APPLICATION = 'config.routing.application'
CHANNEL_LAYERS = {
    'default': {
        'BACKEND': 'channels_redis.core.RedisChannelLayer',
        'CONFIG': {
            "hosts": [('127.0.0.1', 6379)],
        },
    },
}

config.routing.py

from channels.auth import AuthMiddlewareStack
from channels.routing import ProtocolTypeRouter, URLRouter
import myproject.websocket.routing

application = ProtocolTypeRouter({
    'websocket': AuthMiddlewareStack(
        URLRouter(
            myproject.websocket.routing.websocket_urlpatterns
        )
    )
})

websocket url

from django.urls import re_path
from . import consumers

websocket_urlpatterns = [
    re_path(r'ws/socket/$', consumers.WebSocketConsumer),
]

asgi.py

import os

from django.core.asgi import get_asgi_application

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'config.settings')
application = get_asgi_application()

nginx.conf

upstream myproject {
    server unix:///tmp/myproject.sock;
}

upstream channels {
    server localhost:9001;
}

server {
    listen 80;
    server_name myprojectdomain;

    client_max_body_size 100M;

    if ($host !~* ^(myprojectdomain)$ ) {
        return 444;
    }

    location / {
        include /etc/nginx/uwsgi_params;
        uwsgi_params myproject;
    }

    location /static/ {
        alias /home/myproject/httpdocs/static/;
    }

    location /media/ {
        alias /home/myproject/httpdocs/myproject/media/;
    }

    location /ws/ {
        proxy_pass channels;
    }
}

uwsgi.ini

[uwsgi]
virtualenv = /home/myproject/httpdocs/venv
pythonpath = /home/myproject/httpdocs
socket = /tmp/myproject.sock
chmod-socket = 664
module=config.wsgi:application
master = true
daemonize = /var/log/uwsgi/myproject.log
pidfile = /tmp/myproject.pid

(venv) uwsgi --ini config/uwsgi.ini 

(venv) daphne -p 9001 myproject.asgi:application

SOLUTION

I have merged the asgi.py and routing.py files into the asgi.py and I add it some information:

import os
from django.core.asgi import get_asgi_application

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'config.settings')
asgi_app = get_asgi_application()

from channels.auth import AuthMiddlewareStack
from channels.routing import ProtocolTypeRouter, URLRouter
import myproject.websocket.routing

application = ProtocolTypeRouter({
    "http": asgi_app,
    'websocket': AuthMiddlewareStack(
        URLRouter(
            myproject.websocket.routing.websocket_urlpatterns
        )
    )
})

Is important to respect the order of the imports.

Finally my nginx.conf is:

myproject {
    server unix:///tmp/myproject.sock;
}
server {
    listen 80;
    server_name mydomain;

    client_max_body_size 100M;

    if ($host !~* ^(mydomain)$ ) {
        return 444;
    }

    location / {
        include /etc/nginx/uwsgi_params;
        uwsgi_pass myproject;
    }

    location /ws/ {
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_redirect off;
        proxy_pass http://127.0.0.1:8001;
    }

    location /static/ {
        alias /home/myproject/httpdocs/static/;
    }

    location /media/ {
        alias /home/myproject/httpdocs/liszt/media/;
    }
}

Then I execute: (venv) uwsgi --ini config/uwsgi.ini (venv) daphne -b 0.0.0.0 -p 8001 myproject.asgi:application

You should be create a daphne.service file to trigger to keep executing daphne when shell is closed.

I expect that this information can help someone.
