Correct way in new versions of nginx

Turn out my first answer to this question was correct at certain time, but it turned into another pitfall - to stay up to date please check Taxing rewrite pitfalls

I have been corrected by many SE users, so the credit goes to them, but more importantly, here is the correct code:

server {
       listen         80;
       server_name    my.domain.com;
       return         301 https://$server_name$request_uri;
}

server {
       listen         443 ssl;
       server_name    my.domain.com;
       # add Strict-Transport-Security to prevent man in the middle attacks
       add_header Strict-Transport-Security "max-age=31536000" always; 

       [....]
}

I got it working! Here's what I did:

Created /etc/uwsgi/apps-available/myapp.xml:

<uwsgi>
    <socket>/tmp/uwsgi-myapp.sock</socket>
    <plugins>http, python</plugins>
    <chdir>/path/to/directory/containing/python/app</chdir>
    <module>myapp</module><!-- myapp.py from before -->
</uwsgi>

Issued the following commands:

ln -s /etc/uwsgi/apps-available/myapp.xml /etc/uwsgi/apps-enabled/myapp.xml
sudo service uwsgi restart

Updated /etc/nginx/sites-available/default:

server {
    listen 80;
    server_name localhost;
    location / {
        include uwsgi_params;
        uwsgi_pass unix:///tmp/uwsgi-myapp.sock;
    }
}

Restarted NGINX:

sudo service nginx restart

And everything is golden! Obviously, the above is a very simple configuration and one should review the availalbe UWSGI and NGINX options before going to production.

What also worked is in the UWSGI configuration having <socket>127.0.0.1:9090</socket> and leaving the NGINX configuration as it was.

As a final note: UWSGI supports multiple formats for configuration: (INI, XML, and YAML). I had originally tried YAML but the server would fail to start so I tried XML and everything worked fine.

EDIT:

I just tried INI configuration and it worked as well. The equivilant INI file as the XML file above is as follows:

[uwsgi]
socket = /tmp/uwsgi-myapp.sock
plugins = http, pythong
chdir = /path/to/directory/containing/python/app
module = myapp
