linuxserver_test

Ansible playbook to setup then break a LAMP server for testing basic Linux skills. Tested on Centos 7, AlmaLinux 8, and Debian 11.

This is a work in progress. The script may have bugs and is not optimized, especially in how to handle failures.

Installs

• Apache
• PHP 7.3
• Nginx (as a reverse proxy)
• Mariadb 5.5
• WordPress (via wp cli)

Service installations are idempotent.

How it breaks things

1. Changes the port Apache is Listening on (as an ingress from Nginx)
2. Sets a root password for MariaDB to prevent passwordless login
3. The mariadb service is stopped and not enabled to start on boot
4. Configures wp-config.php to use the wrong database connection details
5. wp-config.php is set to immutable
6. chmod 000 /usr/bin/ls
7. Sets iptable chain policies to DROP (except for SSH)

Usage

The playbook needs to be used with one of two tags:

• provision : This tag assumes a fresh server. The playbook will install all services mentioned above then make all breaking changes.

• break : This tag assumes all services are already installed, though not necessarily running/working. The playbook will reapply all breaking changes as necessary.
