Working with uWSGI using unix sockets?

Thanks for this great library!

I’m trying to use it with uWSGI via unix sockets without success, and am wondering if anyone has any ideas. The set up is Python 3.5 + Nginx + uWSGI.

(Sorry if this is not the right place to ask - I hope it may be helpful to others in similar situations.)

The Nginx part is working I think:

server {
  listen 80;

  location / {
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "Upgrade";
    proxy_http_version 1.1;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_pass http://127.0.0.1:5000;
  }
}

And that’s because if I run the uWSGI server using HTTP, it works fine:

uwsgi --http :5000 --gevent 1000 --http-websockets --master --module myapp.wsgi --callable app

But if I run it using unix socket, it doesn’t. I have this Nginx setup:

server {
  listen 5000;

  gzip on;
  gzip_disable "msie6";
  gzip_min_length 1000;
  gzip_vary on;
  gzip_comp_level 6;
  gzip_types text/css application/json application/x-javascript text/javascript;

  location / {
    include uwsgi_params;
    uwsgi_pass unix:///tmp/myapp.sock;
  }
}

and the following uWSGI setup:

[uwsgi]
chdir = /home/ubuntu/myapp
module = myapp.wsgi
callable = app
home = /home/ubuntu/myapp/env

master = true
processes = 10
gevent = 1000
http-websockets = true

socket = /tmp/myapp.sock
chmod-socket = 660
vacuum = true

die-on-term = true

The error is WebSocket is closed before the connection is established.

Oh I got it working. Turns out you can’t specify the process param. Thanks again for the help!

Here’s the working config:

Nginx:

server {
  ...
  (non-socketio can still use uWSGI socket)

  location /socket.io/ {
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_pass http://unix:///tmp/myapp.sock;
  }
}

uWSGI:

master = true
gevent = 500
http-websockets = true

http-socket = /tmp/myapp.sock
chmod-socket = 660
vacuum = true

Nothing fancy there:

location / {
    include uwsgi_params;
    uwsgi_pass unix:///tmp/myapp.sock;
}
