What is UltraStack?

UltraStack is a collection of server settings developed by InMotion Hosting experts, aimed at optimizing server performance for specific content management systems like WordPress.

What is included?

NGINX

NGINX is part of UltraStack and acts as a reverse-proxy and cache, helping your website respond to requests much faster. It uses a short cache time to handle high traffic more effectively and has rules to prevent caching for logged-in users.

PHP-FPM

PHP-FPM stands for FastCGI Process Manager, which is a better way to run PHP. Each PHP-FPM pool acts like an independent installation of PHP, with its own settings and resources.

Redis

Redis stands for Remote Dictionary Server. It speeds up database queries by caching them in the faster memory instead of using the slower hard drive. This makes it easier to handle frequent database requests quickly.

Role Variables

Here are the available variables you can use, along with their default settings (you can also check defaults/main.yml):

Variable	Definition
use_ultrastack	Enables UltraStack configuration by default. Set to false to skip installing NGINX and Redis.
use_redis	Turn Redis installation on or off.
site_domain	The domain you'll use for the service configuration.
ultrastack_w3tc_settings	Additional settings for W3TC if you're installing on an existing WordPress site.
nginx_ratelimit_enable	Turns on/off rate limiting for certain paths in NGINX.
nginx_ratelimit_burst	Sets burst limits for the rate limit zone in NGINX.
nginx_ratelimit_nodelay	Enables or disables delays for the NGINX rate limit zone.
nginx_ratelimit_zone	Name for the NGINX rate limit area.
nginx_ratelimit_paths	Paths that will have rate limiting applied.
nginx_cache_bypass_paths	Paths that will bypass the cache.
nginx_cache_purge_enable	Enables cache purging in NGINX when using a specific module.
nginx_vts_enable	Enables NGINX settings for the VTS module.
nginx_cache_profile	Loads a pre-set profile for NGINX caching.

Note: If you're using UltraStack, it’s highly recommended to also use the w3-total-cache plugin.
