UPDATE: Now you can simply install the https util like so in 1 step:

sudo apt install python3-certbot-nginx

Then execute the utility with:

certbot

Note the python3.

End update.

First off all, you need a domain pointing to your VPS to activate SSL.

To setup SSL follow these steps:

1. Install nginx and use the basic template from this repository. Remember to add your domain name in server_name otherwise you won't be able to add a SSL certificate.

2. Run these commands to install certbot:

sudo add-apt-repository ppa:certbot/certbot
apt-get update
apt-get install python-certbot-nginx

3. Setup your nginx server and install the certificate:

sudo service nginx restart
sudo certbot --nginx -d <YOUR-DOMAIN>.com -d www.<YOUR-DOMAIN>.com

4. That's it! You now should have SSL enabled. Remember to setup pm2 to have a node.js server running all the time.

5. To auto-renew the certificates add a cronjob by doing the following:

• Run: crontab -e
• Then do: 0 12 * * * certbot renew

That will check every day at 12pm and update if necessary. Check this tab generator to verify it: https://crontab.guru/#0_12___*
