4. Create an SSL Certificate for Domain

To allow a domain to function on SSL certbot can be used to generate the certificate. To create the certificate replace the example.com in the below command.

If directed select option 2 to redirect all traffic to the SSL connection.

Run the dry-run certbot command to have the certificate automatically renew itself when its due to be remade.
