Clearing Nginx's HTTP Cache

I recently implemented Nginx HTTP content caching on our WordPress web servers to improve page load speeds and eliminate redundant, unneeded server-side page rendering. Caching the pages was relatively straightforward, but clearing the cache required a custom workaround.

Nginx comes in two versions: free and “Nginx Plus” at $2,500/year. The free version of Nginx does not offer the needed cache-clearing features of Nginx Plus, and I wasn’t comfortable paying $20,000 for 8 instances without trying to build my own solution.

Our Nginx servers run as an HTTP proxy for multiple PHP/MySQL-backed WordPress sites. The goal was to cache the dynamic PHP HTML responses in Nginx and serve the HTML pages from Nginx to avoid redundant, CPU-intensive PHP renders.

- Older version of this gist (without certbot): https://gist.github.com/kocisov/2a9567eb51b83dfef48efce02ef3ab06/33fdd88872a0801bdde58fccce430fa48737ae10
- I would also now recommend deploying to Vercel if you don't need custom server support

1. Install Nginx, Node and certbot

/**

function getMenuItemsFromLocation($location) {
	$theme_locations = get_nav_menu_locations();

	#zero downtime deployment nextjs without vercel

	echo "Deploy starting..."

	git pull

	npm install \|\| exit

	BUILD_DIR=temp npm run build \|\| exit

	// check version
	node -v \|\| node --version

	// list locally installed versions of node
	nvm ls

	// list remove available versions of node
	nvm ls-remote

	// install specific version of node
