Disable/remove Let's Encrypt?

Question

I followed this tutorial to enable Let's Encrypt on my server, however I now want to remove/disable it:

https://www.digitalocean.com/community/tutorials/how-to-secure-nginx-with-let-s-encrypt-on-ubuntu-14-04

How can I do this?

Solution

To remove letsencrypt as installed by that link

rm -rf /opt/letsencrypt

To remove any certs and other letsencrypt stuff

rm -ft /etc/letsencrpt

then disable the server/vhost using the certs and restart apache.
