Afterburner

See how Voce Platforms makes WordPress fly for large, high-traffic, high-profile sites. From server configuration to must-have WordPress plugins to front end optimizations, you'll learn how to make WordPress scale, reduce server resources, and load quickly.

afterburner-ansible is a set of Ansible playbooks and tasks that complement the resources, guides and recommendations at afterburner.voceplatforms.com.

What's included?

• System level tuning and optimizations
• Basic firewall via iptables and fail2ban with blocking of IP addresses that repeatedly send POST requests to various WordPress pages
• NGINX, tuned for WordPress with output level caching
• PHP-FPM, with ZendOptimizerPlus opcode caching
• memcached, for WordPress object level caching
• Percona MySQL
• Basic WordPress application setup (regular install or multi-site)
• Various utilities for monitoring the stack (htop, mytop, strace)

Getting Started

Requirements

1. A server (either bare metal or virtual) with at least 1GB of RAM.
2. Ubuntu 12.04
3. SSH access to your server as a user with 'sudo' ability

Setting up your server

First, get Ansible installed.

Once you have Ansible installed...

1. Clone this repository and cd afterburner-ansible
2. Run ./install. (this copies .sample files for editing)
3. Edit group_vars/ files and change any variables needed to match your application/requirements.
4. Edit hosts and supply the domain names of your server(s).
5. Edit ansible.cfg and change any variables needed to run Ansible tasks against your server(s).
6. Execute ansible all -m ping to ensure Ansible can connect to your hosts
7. Run ansible-playbook site.yml

Visit your application's domain name to view your WordPress install. The wp-admin login details:

• Username: admin
• Password: nsgreoheare

It's strongly recommended you change the default wp-admin login credentials.

To do

• Allow configuring and setting up multiple applications and domains
• Add backup support (Tarnsap? Duplicity to S3?)
• Use ansible facts for wp-config.php database and memcached addresses
