Manage WordPress with Ansible on Ubuntu

This guide will introduce you to Ansible and how you can use it to automate common WordPress tasks, particularly those aimed at optimizing performance.

What is Ansible?

Ansible is an open-source automation tool, or platform, used for IT tasks such as configuration management, application deployment, intraservice orchestration, and provisioning. It uses a simple, human-readable language (YAML) for defining automation jobs, which makes it extremely popular and easy to use.

How to Manage WordPress with Ansible

Ansible allows you to automate repetitive tasks, which can improve the reliability and consistency of those tasks. When it comes to managing WordPress performance on Ubuntu, there are several tasks Ansible can automate:

1. WordPress installation and setup
2. Plugin updates and management
3. Server optimization tasks (e.g., cache clearing, database optimization)
4. Backup management
5. And more…

Preparing your Environment

Before we start with Ansible, ensure you have the necessary environment set up.

1. A Ubuntu server: Make sure you have Ubuntu 18.04 or higher installed on your server.
2. SSH access: You should have SSH access to your server. If not, set this up first.
3. Python installed: Ansible requires Python, ensure Python 2 (version 2.6 or later), or Python 3 (version 3.5 or later) is installed.

Installing Ansible

Now, let’s install Ansible on your Ubuntu machine. Open your terminal and type:

sudo apt update
sudo apt install software-properties-common
sudo apt-add-repository --yes --update ppa:ansible/ansible
sudo apt install ansible

Ansible Basics

There are two key terms you need to understand in Ansible: Playbooks and Roles.

Playbook: A playbook is a YAML file containing a series of procedures that Ansible will execute.

Role: A role is a way of grouping related tasks and configurations into one container. It makes it easier to reuse and share playbooks.

Ansible Playbooks for WordPress Management

Below is an example of an Ansible playbook that installs WordPress, optimizes the database, and manages backups on Ubuntu.

---
- hosts: wordpress
  become: true
  roles:
    - wordpress-install
    - wordpress-optimization
    - wordpress-backup

Here, we’ve grouped tasks into three roles: wordpress-install, wordpress-optimization, and wordpress-backup.

Defining Roles

Next, let’s define each role in the roles directory.

1. Role: wordpress-install

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

- name: Install necessary packages
  apt: 
    name: "{{ item }}" 
    state: latest
  loop:
    - apache2 
    - mysql-server 
    - php 
    - php-mysql 
    - libapache2-mod-php 
    - php-cli

- name: Download WordPress
  get_url:
    url: https://wordpress.org/latest.tar.gz
    dest: /tmp/wordpress.tar.gz

- name: Extract WordPress
  unarchive: 
    src: /tmp/wordpress.tar.gz 
    dest: /var/www/wptbox/
    remote_src: yes

# more tasks for setting up WordPress...

2. Role: wordpress-optimization

This will automate tasks like clearing the cache and optimizing the database.

---
- name: Install WP-CLI
  get_url: 
    url: https://raw.githubusercontent.com/wp-cli/builds/gh-pages/phar/wp-cli.phar
    dest: /usr/local/bin/wp
    mode: '0755'

- name: Run database optimization
  command: 
    cmd: wp db optimize --allow-root
    chdir: /var/www/wptbox/wordpress

3. Role: wordpress-backup

This role handles backups.

---
- name: Install zip
  apt: 
    name: zip
    state: latest

- name: Backup WordPress files
  command: 
    cmd: zip -r /backups/wordpress-files.zip /var/www/wptbox/wordpress
    creates: /backups/wordpress-files.zip

- name: Backup WordPress database
  command: 
    cmd: wp db export --allow-root --path=/var/www/wptbox/wordpress /backups/wordpress-db.sql
    creates: /backups/wordpress-db.sql

Remember to replace the sample values with your actual values where required.

Once you’ve written your playbook and roles, you can run the playbook using the following command:

ansible-playbook wordpress-playbook.yml

Congratulations! You now have an automated WordPress setup, optimization, and backup process in place.
