After following a couple half out of date guides on the internet, I’ve finally been able to create a little green padlock next to my URL in Chrome. Cloudflare provides a free shared certificate that isn’t too difficult to set up provided you have the correct list of steps in front of you.
Step 1 - Fire up a digitalocean droplet with nginx
I am assuming you have a digitalocean droplet set up with Nginx. If not, it’s pretty easy to create a new one with the one-click app for LEMP. You probably don’t need the MySql or PHP, but I think it’s easier to uninstall those than install nginx from scratch, so I just let digitalocean do all the work.
