How to do it...

1. First up, we set up our uwsgi.ini file, which should be located in the root of your Flask application. Here's the file:

      [uwsgi]
      socket = 127.0.0.1:8000
      uid = www-data gid = www-data
      chdir = /var/www/flaskdemo
      module = demoapp
      callable = application
      master = True
      pidfile = /tmp/uwsgi-flaskdemo.pid
      max-requests = 5000
      daemonize = /var/log/uwsgi/flaskdemo.log

For this demo, we have a single Flask file located in /var/www/flaskdemo/demoapp.py.

You can quickly launch your uWSGI service by running the following command:

      uwsgi --ini uwsgi.ini

1. We now need to configure the NGINX server block directive and again I've included this in a separate file (/etc/nginx/conf.d/flask.conf):

      server { 
          listen 80; 
          server_name flaskdemo.nginxcookbook.com;
          access_log /var/log/nginx/flaskdemo-access.log combined;
          location = /favicon.ico { access_log off; log_not_found off; } 
          location / {
              include uwsgi_params;
              uwsgi_pass 127.0.0.1:8000;
              uwsgi_param SCRIPT_NAME '';
          }
      }
