    server_name     $hostname;
    access_log /web/example.com/logs/access.log;
    error_log /web/example.com/logs/error.log;

    location / {
        uwsgi_pass      unix:///run/uwsgi/app/example.com/example.com.socket;
        include         uwsgi_params;
        uwsgi_param     UWSGI_SCHEME $scheme;
        uwsgi_param     SERVER_SOFTWARE    nginx/$nginx_version;
    }

    location /static {
        root   /web/example.com/public_html/static/;
    }
}

Then create a symlink
