PHP 8.1 was released on November 25, 2021, however, it was not available on amazon-linux-extra repo until recently. I have seen users asking for this in various forums and GitHub issues.

Most of the tutorials that you’ll find on the internet are installing PHP 8.1 via the Remi repository. However, I always find it convenient and hassle-free to install packages from a native-supported repository.

And I am happy that PHP 8.1 is already present in amazon-linux-extra repository. So let’s go and install it on our Linux 2 system.

So let’s start with that step.

1. Run System Update

sudo yum update

2. Check If amazon-linux-extras is installed

Usually, Amazon Linux 2 system already comes installed with amazon-linux-extras and you can check it with the below command.

which amazon-linux-extras

As you can see it is installed and you can see the location in the above screenshot.

However, by any chance, If it is not there, you can install it using the below command.

sudo yum install -y amazon-linux-extras

3. Check for Available PHP packages/topics in amazon-linux-extras repo

amazon-linux-extras list | grep php

After running g this command, it shows all the available versions of PHP in the repo as you can see below-

or type

sudo amazon-linux-extras install php8.1

Both the command work equally well and after firing any of the above, you will get below output-

Installed PHP 8.1

Enter y when prompted and your packages get installed on the system.

Note: You’ll have to use sudo(root privilege ) to run the above command. The reason is that whenever you try to install, remove or change any software, you must have root privilege to do such tasks.
