How to Install PHP on Linux (NGINX + PHP Setup Guide)

Now that you have a working NGINX server and a hosted website, it's time to make your server dynamic by installing PHP.

PHP allows your server to run scripts, process forms, and power real web applications.

What Is PHP?

PHP is a server-side scripting language used to create dynamic websites. It powers platforms like WordPress, Laravel, and many web applications.

Step 1: Install PHP

Debian / Ubuntu:

sudo apt install php-fpm php-mysql -y

Red Hat / Rocky / Fedora:

sudo dnf install php php-fpm php-mysqlnd -y

Step 2: Start PHP-FPM

sudo systemctl start php8.3-fpm

Or (depending on system):

sudo systemctl start php-fpm

Step 3: Enable PHP at Boot

sudo systemctl enable php8.3-fpm

Step 4: Configure NGINX for PHP

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

Add this inside your server block:

location ~ \.php$ {
    include snippets/fastcgi-php.conf;
    fastcgi_pass unix:/run/php/php8.3-fpm.sock;
}

Step 5: Restart NGINX

sudo systemctl restart nginx

Step 6: Create a PHP Test File

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

Add:

<?php
phpinfo();
?>

Step 7: Test in Browser

Go to:

http://your-server-ip/info.php

If you see the PHP info page, everything is working!

• Check PHP-FPM status
• Verify socket path
• Restart NGINX
