Integrate PHP-FPM with Nginx on Ubuntu 24.04

Prerequisites

• Nginx installed and running
• PHP-FPM installed (see Install PHP-FPM on Ubuntu 24.04)

Step 1 – Confirm PHP-FPM socket path

grep -E '^listen' /etc/php-fpm.d/www.conf 2>/dev/null || \
grep -E '^listen' /etc/php/*/fpm/pool.d/www.conf 2>/dev/null

Default socket: /run/php/php8.3-fpm.sock

Step 2 – Update the Nginx server block

server {
    listen 80;
    server_name example.com;
    root /var/www/example.com/html;
    index index.php index.html;

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

    location ~ \.php$ {
        include        fastcgi_params;
        fastcgi_pass   unix:/run/php/php8.3-fpm.sock;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME $document_root$fastcgi_script_name;
    }

    location ~ /\.ht {
        deny all;
    }
}

Step 3 – Test configuration and reload

nginx -t && systemctl reload nginx 2>/dev/null || \
nginx -t && rc-service nginx reload 2>/dev/null || \
nginx -t && rcctl reload nginx

Step 4 – Create a test PHP file

echo '<?php phpinfo(); ?>' > /var/www/example.com/html/info.php

Visit http://example.com/info.php in a browser. Remove the file afterwards:

rm /var/www/example.com/html/info.php
