Install PHP 8.0 on Amazon Linux 2

Install the yum-utils package which provides yum-config-manager command line tool.

sudo yum -y install yum-utils

Method 1: Install PHP 8.0 from OS repositories

Let’s confirm that PHP 8.0 topic is available in our Amazon Linux 2 machine:

$ sudo  amazon-linux-extras | grep php
 15  php7.2                   available    \
 17  lamp-mariadb10.2-php7.2  available    \
 31  php7.3                   available    \
 42  php7.4                   available    [ =stable ]
 51  php8.0                   available    [ =stable ]

We can confirm php8.0 topic is available. Let’s enable it.

sudo yum-config-manager --disable 'remi-php*'
sudo amazon-linux-extras enable php8.0 

After repo is enabled, install PHP 8.0 on Amazon Linux 2 with standard PHP extensions.

sudo yum clean metadata
sudo yum install php-pear,cgi,pdo,common,curl,mbstring,gd,mysqlnd,gettext,bcmath,json,xml,fpm,intl,zip
