django with nginx uwsgi bad gateway 502

i want to run django with nginx i followed this instructions and in

/etc/nginx/sites-available/cartoview_one

upstream django {
    server unix:///root/cartoview_project/mysite.sock; # for a file socket    }

server {
    listen      80;
    server_name xx.xx.xx.xx;
    charset     utf-8;

    # max upload size
    client_max_body_size 2048M;   # adjust to taste

    # Django media
    location /media  {
        alias /root/cartoview_project/uploaded;
    }

    location /static {
        alias /root/cartoview_project/static;
    }
    location / {
        uwsgi_pass  django;
        include     /root/cartoview_project/uwsgi_params; # the uwsgi_params file you installed
    }
}

then created symlink using:

sudo ln -s /etc/nginx/sites-available/cartoview_one /etc/nginx/sites-enabled

and in project folder mysite_uwsgi.ini:

[uwsgi]
project = cartoview_project
chdir           = /root/cartoview_project
module          = %(project).wsgi:application
home            = /root/env
master          = true
processes       = 10
socket          = /root/cartoview_project/mysite.sock
chmod-socket = 666
vacuum          = true
http-socket = 0.0.0.0:80

project structure :

.
|-- apps
|-- cartoview_project
|   |-- __init__.py
|   |-- __init__.pyc
|   |-- local_settings.py
|   |-- local_settings.pyc
|   |-- local_settings.py.sample
|   |-- settings.py
|   |-- settings.pyc
|   |-- urls.py
|   |-- wsgi.py
|   `-- wsgi.pyc
|-- default_oauth_apps.json
|-- initial_data.json
|-- manage.py
|-- mysite_uwsgi.ini
`-- uwsgi_params

when i try to access website with myip this message appear :

502 Bad Gateway

nginx/1.10.0 (Ubuntu)

error.log :

2017/02/06 09:46:41 [crit] 6867#6867: *1 connect() to unix:///root/cartoview_project/mysite.sock failed (13: Permission denied) while connecting to upstream, client: xx.xx.xxx.xxx, server: xxx.xxx.xxx.xxx, request: "GET / HTTP/1.1", upstream: "uwsgi://unix:///root/cartoview_project/mysite.sock:", host: "xxx.xxx.xxx.xxx"

Update :

i removed http-socket and run the following command /root/env/bin/uwsgi --ini mysite_uwsgi.ini and mysite.sock appeared in project then restart nginx but nothing changed.

:~/cartoview_project# stat mysite.sock

From the description, it looks like you haven't run your uwsgi process - a 502 error at this point means that nginx is passing the response through correctly, but there's nothing for it to connect to, or it's not getting the correct response.

which uwsgi will give you the path for the appropriate uwsgi (do this inside your virtualenv if you're running one).

e.g.

/root/cartoview_project/uwsgi --ini mysite_uwsgi.ini

You should take the http-socket config variable out of uwsgi though - nginx is listening on port 80, and passing it through to your .sock file created by your uwsgi app.
