Populate this cartography with the IP addresses or domain names of your hosts, categorizing them as needed.

ini
[web_servers]
192.168.1.101
192.168.1.102

[database_servers]
192.168.1.201

With this ledger of hosts, Ansible gains insight into the castles it is to conquer or the fields it is to sow.

Deploying PHP Applications with Ansible

Now that Ansible has set its roots and acquainted itself with the lay of the land, let’s explore the deployment of PHP applications. Ansible playbooks, akin to the scripts of a theatrical production, orchestrate the symphony of tasks required for deployment.

Create a playbook, perhaps named deploy_php_app.yml, and let the drama unfold:

yaml
---
- name: Deploy PHP Application
  hosts: web_servers
  become: true

  tasks:
    - name: Update apt cache
      apt:
        update_cache: yes

    - name: Install PHP and Apache
      apt:
        name:
          - php
          - apache2
        state: present

    - name: Copy PHP application files
      copy:
        src: /path/to/your/app
        dest: /var/www/html/
      notify: Restart Apache

  handlers:
    - name: Restart Apache
      service:
        name: apache2
        state: restarted

In this tale, Ansible dances through tasks—updating the apt cache, installing PHP and Apache, and copying your PHP application files to their designated stage. The handlers, like the stagehands behind the curtain, wait for their cue to restart Apache once the files are in place.

Executing the Playbook

With the playbook penned, the grand performance awaits. Execute the masterpiece with the following command:

bash
ansible-playbook deploy_php_app.yml

Watch as Ansible, the virtuoso of automation, orchestrates the deployment of your PHP application across the web_servers ensemble.
