Step 6 : Edit your Nginx configuration file for your site (e.g., example.com) to include PHP processing directives.
sudo nano /etc/nginx/sites-available/example.com
server {
listen 80;
server_name example.com www.example.com;
root /var/www/html/example.com;
index index.php index.html index.htm;
location / {
try_files $uri $uri/ =404;
}
location ~ \.php$ {
include snippets/fastcgi-php.conf;
fastcgi_pass unix:/var/run/php/php8.3-fpm.sock;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
location ~ /\.ht {
deny all;
}
error_log /var/log/nginx/example.com_error.log;
access_log /var/log/nginx/example.com_access.log;
}
Step 7 : Enable your Nginx site configuration file by creating a symbolic link from the sites-available directory to the sites-enabled directory.
sudo ln -s /etc/nginx/sites-available/example.com /etc/nginx/sites-enabled/
Step 8 : Check the syntax of your Nginx configuration to ensure there are no errors:
sudo nginx -t
Step 9 : Restart Nginx to apply the changes:
sudo systemctl restart nginx
Step 10 : Create a PHP file (e.g., info.php) in your web root directory
sudo nano /var/www/html/example.com/info.php
Add the following line:
<?php
phpinfo();
?>
Step 11 : Navigate to your domain (e.g., http://example.com/info.php) in a web browser to see the PHP information page.
Congratulations! You have successfully installed PHP 8.3 for Nginx on Ubuntu 24.04.
