Finally, a potential problem is that users may access our site via port 
80
, instead of 
utilizing HTTPS. We can tell NGINX to forward these people to the secure version 
of our site automatically. To do that, we can edit the default configuration file (
/etc/
nginx/sites-available/default
) and add the following line just after the two 
listen
 
directives:
return 301 https://$host$request_uri; 
Now, anytime a user visits the HTTP version of our site, they'll be redirected to the 
secure HTTPS version automatically.

take a moment to discuss 
keepalived
, which can help us achieve high availability as 
well.
