Installing PHP-FPM with Nginx on Ubuntu 22.04, 20.04, and CentOS

A Comprehensive Guide

Introduction:
PHP-FPM (FastCGI Process Manager) is a PHP FastCGI implementation that provides efficient processing for PHP applications. When combined with Nginx, it enables high-performance web serving and dynamic content generation. This guide will walk you through the installation process of PHP-FPM with Nginx on Ubuntu 22.04, 20.04, and CentOS.

1. Installing PHP-FPM with Nginx on Ubuntu 22.04:

Step 1: Install PHP-FPM and Nginx:

sudo apt update
sudo apt install nginx php-fpm

Step 2: Configure PHP-FPM:
Edit the PHP-FPM configuration file:

sudo nano /etc/php/{PHP_VERSION}/fpm/php.ini

Replace {PHP_VERSION} with your installed PHP version.
Ensure the following configurations are set:

cgi.fix_pathinfo=0

Step 3: Restart PHP-FPM Service:

sudo systemctl restart php{PHP_VERSION}-fpm

Replace {PHP_VERSION} with your installed PHP version.

Step 4: Configure Nginx to Use PHP-FPM:
Edit the default Nginx server block configuration:

sudo nano /etc/nginx/sites-available/default

Add the following lines within the server block:

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

Replace {PHP_VERSION} with your installed PHP version.

Step 5: Test Nginx Configuration and Restart Nginx:

sudo nginx -t
sudo systemctl restart nginx

2. Installing PHP-FPM with Nginx on Ubuntu 20.04:

Repeat the steps above for Ubuntu 20.04. PHP-FPM installation and configuration process remains the same across Ubuntu versions.

3. Installing PHP-FPM with Nginx on CentOS:

Step 1: Install PHP-FPM and Nginx:

sudo yum install epel-release
sudo yum install nginx php-fpm

Step 2: Configure PHP-FPM:
Edit the PHP-FPM configuration file:

sudo nano /etc/php-fpm.d/www.conf

Ensure the following configurations are set:

listen = /var/run/php-fpm/php-fpm.sock

Step 3: Restart PHP-FPM Service:

sudo systemctl restart php-fpm

Step 4: Configure Nginx to Use PHP-FPM:
Follow the same configuration steps as outlined for Ubuntu.

By following these steps, you can successfully install PHP-FPM with Nginx on Ubuntu 22.04, 20.04, and CentOS, providing a powerful platform for hosting dynamic web applications.
