Introduction
This tutorial will guide you through the process of installing PHP versions 5.6 and 7.0 through 8.3 with PHP-FPM and FastCGI mode for ISPConfig 3.2 on Ubuntu 18.04 through 22.04. ISPConfig is an open-source hosting control panel for Linux which allows you to manage multiple servers from a single control panel.
Prerequisites
Before you begin, ensure you have:
- An Ubuntu server running version 18.04, 20.04, or 22.04
- SSH access to the server
- Root or sudo privileges
Step 1: Add PHP Repository
Add the ondrej/php repository which provides multiple PHP versions:
sudo apt update
sudo apt install software-properties-common -y
sudo add-apt-repository ppa:ondrej/php
sudo apt update
Step 2: Install PHP Versions
Install the desired PHP versions along with PHP-FPM:
sudo apt install php5.6-fpm php7.0-fpm php7.1-fpm php7.2-fpm php7.3-fpm php7.4-fpm php8.0-fpm php8.1-fpm php8.2-fpm php8.3-fpm -y
Step 3: Configure PHP-FPM
Edit the PHP-FPM configuration file for each PHP version:
sudo nano /etc/php/5.6/fpm/pool.d/www.conf
sudo nano /etc/php/7.0/fpm/pool.d/www.conf
sudo nano /etc/php/7.1/fpm/pool.d/www.conf
sudo nano /etc/php/7.2/fpm/pool.d/www.conf
sudo nano /etc/php/7.3/fpm/pool.d/www.conf
sudo nano /etc/php/7.4/fpm/pool.d/www.conf
sudo nano /etc/php/8.0/fpm/pool.d/www.conf
sudo nano /etc/php/8.1/fpm/pool.d/www.conf
sudo nano /etc/php/8.2/fpm/pool.d/www.conf
sudo nano /etc/php/8.3/fpm/pool.d/www.conf
Modify the listen directive to use a socket instead of TCP:
listen = /var/run/php/php{version}-fpm.sock
Replace {version} with the respective PHP version (e.g., 5.6, 7.0, etc.).
Save the file and exit the text editor.
Step 4: Restart PHP-FPM Services
Restart PHP-FPM services for each PHP version:
sudo systemctl restart php5.6-fpm
sudo systemctl restart php7.0-fpm
sudo systemctl restart php7.1-fpm
sudo systemctl restart php7.2-fpm
sudo systemctl restart php7.3-fpm
sudo systemctl restart php7.4-fpm
sudo systemctl restart php8.0-fpm
sudo systemctl restart php8.1-fpm
sudo systemctl restart php8.2-fpm
sudo systemctl restart php8.3-fpm
Step 5: Configure FastCGI for ISPConfig
Configure ISPConfig to use FastCGI and PHP-FPM for each PHP version:
sudo nano /etc/apache2/conf-available/ispconfig.conf
Add the following lines for each PHP version:
ProxyPassMatch ^/(.*\.php(/.*)?)$ fcgi://unix:/var/run/php/php{version}-fpm.sock|fcgi://localhost/var/www/ispconfig/{domain}/web/$1
Replace {version} with the respective PHP version (e.g., 5.6, 7.0, etc.).
Save the file and exit the text editor.
Enable the FastCGI configuration:
sudo a2enconf ispconfig
sudo systemctl restart apache2
Step 6: Verify PHP-FPM Configuration
Verify that PHP-FPM is running and listening on the specified sockets:
sudo systemctl status php{version}-fpm
Replace {version} with the respective PHP version (e.g., 5.6, 7.0, etc.).
Conclusion
You have successfully installed PHP versions 5.6 and 7.0 through 8.3 with PHP-FPM and FastCGI mode for ISPConfig 3.2 on Ubuntu 18.04 through 22.04. You can now configure virtual hosts in ISPConfig to use different PHP versions for your websites and web applications.
