Step-by-Step Guide: How to Set up / Upgrade to PHP 8.2 on Ubuntu/Debian

Step-by-Step Guide: How to Set up / Upgrade to PHP 8.2 on Ubuntu/Debian

Sure, I can provide you with a step-by-step guide on how to set up or upgrade to PHP 8.2 with FPM (FastCGI Process Manager) on both Apache and Nginx web servers on Ubuntu/Debian. Please note that the specific steps may vary depending on the exact versions of software and your system configuration, so it’s always a good idea to refer to the official documentation as well.

Step 1: Update your system Before installing PHP 8.2, it’s a good practice to update your system’s package list and upgrade existing packages:

sudo apt update sudo apt upgrade

Step 2: Install PHP 8.2

sudo apt install software-properties-common
sudo add-apt-repository ppa:ondrej/php
sudo apt update
sudo apt install php8.2 php8.2-fpm php8.2-mysql php8.2-curl php8.2-xml php8.2-json php8.2-opcache php8.2-mbstring php8.2-zip

You can include additional PHP extensions as needed for your specific application.

Step 3: Configure PHP-FPM

Edit the PHP-FPM pool configuration file:

sudo nano /etc/php/8.2/fpm/pool.d/www.conf

Make sure the listen directive points to the correct socket or IP address/port, and adjust other settings as needed. Save and close the file.

Step 4: Configure Apache

sudo apt install apache2
sudo a2enmod proxy_fcgi setenvif
sudo a2enconf php8.2-fpm
sudo systemctl restart apache2

Step 5: Configure Nginx

sudo apt install nginx

Create a new server block configuration for Nginx:

sudo nano /etc/nginx/sites-available/example.com

Replace example.com with your domain name, and add the following configuration:

server {
    listen 80;
    server_name example.com www.example.com;

    root /var/www/example.com;
    index index.php;

    location / {
        try_files $uri $uri/ /index.php?$args;

    location ~ \.php$ {
        include snippets/fastcgi-php.conf;
        fastcgi_pass unix:/run/php/php8.2-fpm.sock;

    location ~ /\.ht {
        deny all;

Enable the server block and restart Nginx:

sudo ln -s /etc/nginx/sites-available/example.com /etc/nginx/sites-enabled/ 
sudo systemctl restart nginx

Step 6: Test PHP

Create a test PHP file in your web server’s document root:

sudo nano /var/www/html/info.php

Add the following code:

<?php phpinfo(); ?>

Access the file in your browser (http://your_domain/info.php) to verify that PHP 8.2 is installed and configured correctly.

Remember that these steps provide a general guide. Your specific server configuration and needs might require additional steps or adjustments. Always refer to the official documentation of PHP, Apache, and Nginx for the most up-to-date and accurate instructions.
