Step 6 : Install frequently used PHP extensions:

sudo dnf install -y php-{fpm,mysqlnd,curl,gd,mcrypt,json,pear,common,xml,zip,devel,xsl,soap,bcmath,mbstring,gettext,imagick}

- fpm: Handles PHP requests via FastCGI for Nginx.

Step 7 : Edit the PHP-FPM configuration file:

Replace user = apache and group = apache with:

user = nginx  
group = nginx

Step 8 : Enable and start the PHP-FPM service:

sudo systemctl enable php-fpm  
sudo systemctl start php-fpm

Step 9 : Check the PHP version to confirm the installation:

php -v

Step 10 : To configure Nginx to use PHP, create or edit the domain configuration file (e.g., /etc/nginx/conf.d/example.com.conf):

server {
    listen 80;
    server_name example.com;

    location / {
        root /usr/share/nginx/html;
        index index.php index.html index.htm;
    }

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

Step 11 : Verify the Nginx configuration for syntax errors:

sudo nginx -t

Step 12 : Restart the Nginx service to apply the changes:

sudo systemctl restart nginx

Step 13 : Create a PHP info file to test the setup:

sudo echo "<?php phpinfo(); ?>" > /usr/share/nginx/html/info.php

Step 14 : Access the Info Page

Visit http://example.com/info.php in your browser. You should see the PHP info page displaying PHP 8.4 details.

Congratulations! You have successfully installed PHP 8.4 for Nginx on CentOS Stream 10.
