How to bind Daphne on a unix socket?

Question

So far, I've used Gunicorn, with this configuration file systemd:

[Unit]
Description=gunicorn daemon
After=network.target


[Service]
EnvironmentFile=/var/www/user/.envvars
User=user
Group=www-data
WorkingDirectory=/var/www/user
ExecStart=/var/www/venv/bin/gunicorn --workers 3 --bind unix:/var/www/user/user.sock config.wsgi:application --env DJANGO_SETTINGS_MODULE='config.settings.production'

[Install]
WantedBy=multi-user.target

And Nginx proxy requests for this unix socket.

Trying Daphne, I realized that I can not specify --env DJANGO_SETTINGS_MODULE='config.settings.production'

But I specify this variable in asgi.py, on it all is normal.

As soon as I ran the gunicorn service, the socket itself was instantly created on which requests from nginx.

When I try to do the same trick with Daphne, I get an error:

Jun 26 11:48:32 p435061.kvmvps daphne[8447]: ValueError: invalid literal for int() with base 8: '/var/www/user/user.sock'

But I can not figure out how to use the unix.sock when I try to run Daphne and create my systemd file

UPDATE

I changed the settings file, and it gives something strange, but it works:

[Unit]
Description=daphne daemon
After=network.target


[Service]
EnvironmentFile=/var/www/gglobal/.envvars
User=gglobal
Group=www-data
WorkingDirectory=/var/www/gglobal
ExecStart=/var/www/venv/bin/daphne -b unix:/var/www/gglobal/gglobal.sock  config.asgi:channel_layer -v2

systemctl status daphne returns:

But nginx swears at the lack of a *.sock file:

2017/06/26 17:47:51 [crit] 12682#12682: *59 connect() to unix:/var/www/project/project.sock failed (2: No such file or directory) while connecting to upstream, client: 5.152.1.201, server: mydomain.com, request: "GET / HTTP/2.0", upstream: "http://unix:/var/www/project/project.sock:/", host: "mydomain.com"

I spent the whole day fighting this, but nothing happened.

Answer 1

The answer was quite simple:

The problem was that I pointed out -b unix:, and the unix: prefix interfered with the work, and, of course, the flag should be set -u
