python - Websocket connection by Apache2 + mod_wsgi + Django -


i deploying django project on apache2 using mod_wsgi. can confirm see django's page apache2 server websocket cannot connect, think django-channels doesn't start apache2.

so solve problem install 'asgi_redis' start django-channels.

'pip3 instal asgi_redis'

i changed channel layer.

channel_layers = {     "default": {         "backend": "asgi_redis.redischannellayer",             "config": {             "hosts": [("localhost", 6379)],              },             "routing": "mysite.routing.channel_routing",     }, }

and tried follow command.

'python3 manage.py runworker'

but following error occured.
