Steps To Install and Run PHP 8.3 on Linux Mint 21

Before you start your PHP installation, you must have access to your Linux Mint server as a non-root user with sudo privileges. Now proceed to the following steps to complete this guide.

Step 1 – Enable PPA Repository For PHP on Linux Mint 21

First, you must install the required packages and add the PPA repository for PHP installation in Linux Mint. To do this, you can run the following commands:

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

When you are done, run the system update and upgrade with the command below:

sudo apt update && sudo apt upgrade -y

Step 2 – Install PHP 8.3 with Apache on Mint 21

At this point, you can install PHP 8.3 for the Apache module by using the command below:

sudo apt install php8.3 libapache2-mod-php8.3 -y

Then, restart Apache to apply the changes:

sudo systemctl restart apache2

Also, you can install Apache with the PHP-FPM module. To do this, use the command below:

sudo apt install php8.3-fpm libapache2-mod-fcgid

Step 3 – Enable PHP-FPM For Apache on Mint 21

As you may know, PHP-FPM is not enabled for Apache. To enable it, you must run the following command:

sudo a2enmod proxy_fcgi setenvif && sudo a2enconf php8.3-fpm

sudo systemctl restart apache2

Now you can verify your PHP-FPM is active and running in Linux Mint 21:

Then, verify your PHP-FPM is enabled on your server with the command below:

sudo systemctl status php8.3-fpm

Also, you need to edit your Nginx server block and add the example below for Nginx to process the PHP files on Linux Mint 21.

server {
# … some other code
location ~ .php$ {
include snippets/fastcgi-php.conf;
fastcgi_pass unix:/run/php/php8.3-fpm.sock;
}

Test Nginx to make sure you have no errors with the adjustments made with the code above; enter the following command:
