These instructions assume that you already have nginx or Apache set up for your local development environment. I'll put together some more detailed instructions in a later post for starting completely from scratch. This gets you from Magento 2.4.3 or lower to Magento 2.4.4.

First, you have to install php 8.1:

sudo apt install software-properties-common && sudo add-apt-repository ppa:ondrej/php -y
sudo apt update

Now install all of the php 8.1 modules:

sudo apt -y install php8.1-bcmath php8.1-common php8.1-curl php8.1-fpm php8.1-gd php8.1-intl php8.1-mbstring php8.1-mysql php8.1-soap php8.1-xml php8.1-xsl php8.1-zip php8.1-cli

Edit the FPM php.ini to increase PHP limitations to Magento 2.4.4's minimum requirements:

Edit /etc/php/8.1/fpm/php.ini

Find memory_limit and change it to memory_limit=1024M

Magento 2.4.4 can get by with 768M but it seems to do a little better with some extra.

Find max_execution_time and change it to max_execution_time=36000 or max_execution_time=-1

Note: This is for LOCAL DEVELOPMENT ONLY. Don't set a production environment up like this.

Change zlib.output_compression to zlib.output_compression=1

Save the file and exit the text editor. Restart php with sudo service php8.1-fpm restart and nginx (or Apache) to be safe.
