-====== FAH Removal ======
-In our previous step we [[fah_installation|set up FAH]] on our [[Stack of NUCs]].
-Now we are going to disable the service and uninstall it. In the last step there was an optional step to "finish folding". Bonus points for doing this.
-Purpose:
-  * Demonstrate stopping and removing an installed service workload
-====== Step 1 - Connect to the Ansible Control Node ======
-From [[stack - nuc 1|NUC 1]], log in to the Ansible control node, [[stack - nuc 2|NUC 2]].
-====== Step 2 - Create the Playbook ======
-Create the file /home/ansible/my-project/fah/removefah.yml
-<file yaml removefah.yml>

-====== Step 3 - Test the Playbook ======
-''ansible-playbook removefah.yml''
-Now that we have removed the CPU-hungry FAH service, we go next to [[Install Kubernetes|installing Kubernetes]]
-====== Optional ======
-Cyber security students may want to deploy hashtopolis in the Lab. This deploys a distributed hashcat cluster for brute forcing password hashes.
