Question

Connection refused with uwsgi and nginx

followed one of the tutorials on digitalocean to be able to set up a flask app using uwsgi and nginx.

But I am having a 502 Bad Gateway error everytime I try to connect to it. When looking in the /var/log/nginx/errors.log it shows that the connection was refused.

I have been trying to figure this out for days. Can someone please tell me whats wrong? I think it’s the permissions but I dont know what the permissions are suppose to be.

/var/log/nginx/error.log:

2016/08/01 16:12:13 [error] 18539#18539: *1 connect() to unix:/home/lit/howlit/how_lit_restapi.sock failed (111: Connection refused) while connecting to upstream,

here is my howlit.ini file:

[uwsgi]
module = wsgi:app


master = true
processes = 5


socket = how_lit_restapi.sock

chmod-sock = 666

vaccum = true

die-on-term = true

Here is my permissions in the app directory:

drwx---r-x 6 lit www-data 4096 Jul 29 11:47 env
-rwx---r-x 1 lit www-data  141 Jul 29 19:01 howlit.ini
-rwx---r-x 1 lit www-data 1175 Jul 29 11:52 how_lit_restapi.py
-rwx---r-x 1 lit www-data 1781 Jul 29 11:54 how_lit_restapi.pyc
srwx---r-x 1 lit www-data    0 Jul 29 16:46 how_lit_restapi.sock
-rwx---r-x 1 lit www-data   73 Jul 29 11:54 wsgi.py
-rwx---r-x 1 lit www-data  218 Jul 29 11:54 wsgi.pyc

Here is my nginx config file in /etc/nginx/sites-enabled file:

root@digitalocean:~# cat /etc/nginx/sites-enabled/how_lit 
server {
    listen 80;
    server_name XXX.XX.XX;

    location / {
        include uwsgi_params;
        uwsgi_pass unix:/home/lit/howlit/how_lit_restapi.sock;
    }
}

The XXX.XX.XX has a real ip address didnt want to put mine out there.
