How to Install PHP 8.0 on Ubuntu 20.04 or 18.04

1 Answer(s)

    let’s update your Ubuntu system packages and install some dependencies as shown.

    $ sudo apt update
    $ sudo apt upgrade
    $ sudo apt install  ca-certificates apt-transport-https software-properties-common

    Next, add the Ondrej PPA.

    $ sudo add-apt-repository ppa:ondrej/php

    When prompted, press ENTER to proceed with adding the repository.

    Step 2: Install PHP 8.0 with Apache on Ubuntu

    Next, update the system repositories to start using the PPA.

    $ sudo apt update

    If you are running the Apache web server, install PHP 8.0 with the Apache module as shown.

    $ sudo apt install php8.0 libapache2-mod-php8.0

    Next, restart the Apache webserver to enable the module.

    $ sudo systemctl restart apache2

    If you want to use Apache webserver with PHP-FPM, run the command below to install the required packages:

    $ sudo apt install php8.0-fpm libapache2-mod-fcgid

    Since PHP-FPM is not enabled by default, enable it by invoking the following commands:

    $ sudo a2enmod proxy_fcgi setenvif
    $ sudo a2enconf php8.0-fpm

    Then restart the Apache webserver for the changes to come into effect.

    $ sudo systemctl restart apache2

    Verify PHP 8 Installation in Ubuntu

    To confirm the version of PHP installed, run the command:

    $ php -v
