Follow the prompts to secure your MySQL installation by setting a root password.

Step 4 – Install PHP and Necessary Extensions:
PHP, the scripting language for dynamic content, and essential extensions should be installed:

sudo dnf install php-fpm php-mysqlnd

Step 5 – Configure Nginx for PHP:
Create a new server block configuration for your web application in “/etc/nginx/conf.d/your_domain.conf” (replace your_domain with your actual domain or project name):

server {
    listen 80;
    server_name your_domain.com www.your_domain.com;

    root /var/www/your_domain;
    index index.php index.html;

    location / {
        try_files $uri $uri/ =404;
    }

    location ~ \.php$ {
        include fastcgi_params;
        fastcgi_pass unix:/run/php-fpm/www.sock;
    }

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

Reload Nginx to apply the changes:

sudo systemctl reload nginx

Step 6 – Create Web Root Directory and Test PHP:
Create the directory for your website files and test PHP-FPM with a PHP info file:

sudo mkdir -p /var/www/your_domain
sudo chown -R nginx:nginx /var/www/your_domain
echo "<?php phpinfo(); ?>" | sudo tee /var/www/your_domain/info.php

Access the PHP test page by visiting http://your_domain/info.php in your browser.

Step 7 – Secure MySQL Installation:
Enhance MySQL security by running the security script:

sudo mysql_secure_installation

Congratulation!!
You’ve successfully installed and configured a LEMP stack on your CentOS server. The combination of Linux, Nginx, MySQL, and PHP provides a solid foundation for hosting and serving dynamic web applications. You’re now well-equipped to develop and deploy your web projects efficiently and securely.
