Yes, but remember: uwsgi is a communication protocol (like http or
fastcgi), uWSGI is the application server.
You need to start uWSGI, and configure nginx to speak with it with the
protocol of choice (uwsgi, http or fastcgi)

nginx does not work in that way, but it should be not a problem for you as
upstream modules (http, fastcgi, scgi, uwsgi) are compiled in by default.

you need nothing particular:

include uwsgi_params;
uwsgi_pass <address>;

all the other options are for fine tuning.

I suggest you to start from here:

you can proxy nginx to whatever you want/need if the backend speaks one of
the supported protocol (http, scgi, fastcgi, uwsgi)
