What could be the issue ?

# configuration of the server
server {
    # the port your site will be served on
    listen      8000;
    # the domain name it will serve for
    server_name mytest.com; # substitute your machine's IP address or FQDN
    charset     utf-8;

    # Django media
    location /media  {
        alias /home/karesh/tutorial/uwsgi-tutorial/mysite/media;  # your Django project's media files - amend as required
    }

    location /static {
        alias /home/karesh/tutorial/uwsgi-tutorial/mysite/static; # your Django project's static files - amend as required
    }

    # Finally, send all non-media requests to the Django server.
    location / {
        uwsgi_pass  unix:/home/karesh/tutorial/uwsgi-tutorial/mysite/mysite.sock;
        include     /home/karesh/tutorial/uwsgi-tutorial/mysite/uwsgi_params; # the uwsgi_params file you installed
    }
}

uwsgi_params file inside project directory

uwsgi_param  QUERY_STRING       $query_string;
uwsgi_param  REQUEST_METHOD     $request_method;
uwsgi_param  CONTENT_TYPE       $content_type;

uwsgi_param  SERVER_PROTOCOL    $server_protocol;
uwsgi_param  REQUEST_SCHEME     $scheme;
uwsgi_param  HTTPS              $https if_not_empty;

Answer 1

A few things, that could help you: 1) Add user, that runs uWSGI, to nginx group 2) On CentOS with enabled SE the best way to put socket is a directory under /run 3) Set socket permissions to <your_user>:nginx (in other words - set permission for socket for your user and for nginx group.

These steps normally helps me to figure out with permissions error.
