Cleaning up

You can uninstall the entire Piwigo installation using an

Ansible playbook. This has to happen in the reverse order.

You have to remove Piwigo first, followed by PHP, MySQL

and Apache. A playbook to do this is included in the

playbooks/admin folder and given below for reference:

---

• name: Uninstall Piwigo
  hosts: ubuntu
