   sudo apt install software-properties-common -y
sudo add-apt-repository ppa:ondrej/php -y
sudo apt update
2. Install PHP 8.2 with necessary extensions:

   php -v
4. Enable and start PHP-FPM:
   sudo systemctl enable php8.2-fpm
sudo systemctl start php8.2-fpm

Step 5: Configure Nginx to Use PHP

Now, configure Nginx to serve PHP files.

1. Remove the default configuration:
   sudo rm /etc/nginx/sites-enabled/default
2. Create a new Nginx server block:
   sudo nano /etc/nginx/sites-available/example.com
   Replace example.com with your domain or IP and add the following configuration:
   
   server {
listen 80; server_name example.com www.example.com;
root /var/www/html;
index index.php index.html index.htm;
location / {
try_files $uri $uri/ =404;
}
location ~ \.php$
{
include snippets/fastcgi-php.conf;
fastcgi_pass unix:/run/php/php8.2-fpm.sock;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params;
}
location ~ /\.ht
{
deny all;
}
}
   
3. Save the file (CTRL + X, then Y, then ENTER).
4. Enable the new site:
   sudo ln -s /etc/nginx/sites-available/example.com /etc/nginx/sites-enabled/
5. Test Nginx configuration:
   sudo nginx -t
6. Reload Nginx to apply changes:
   sudo systemctl reload nginx

---

Step 6: Test PHP

1. Create a PHP info page:
   sudo nano /var/www/html/info.php
2. Add the following content:
   <?php phpinfo(); ?>
3. Save the file and visit:
   http://your-server-ip/info.php I
   f PHP is working, you’ll see the PHP info page.

Step 7: Secure Your Server

1. Remove the test PHP file (for security reasons):
   sudo rm /var/www/html/info.php
2. Enable the UFW firewall:
   sudo ufw allow OpenSSH
sudo ufw allow 'Nginx Full'
sudo ufw enable
3. Set up an SSL Certificate (Optional, Recommended)
   If you have a domain, install Let’s Encrypt SSL:
   sudo apt install certbot python3-certbot-nginx -y
sudo certbot --nginx -d example.com -d www.example.com
   Auto-renew SSL:
   sudo systemctl enable certbot.timer

---

Step 8: Install phpMyAdmin (Optional)

If you need a web-based database management tool, install phpMyAdmin:

sudo apt install phpmyadmin -y

During installation:

• Select Apache (even though you’re using Nginx) and press TAB to continue.
• Select No when asked to configure the database automatically.

Now, configure Nginx to serve phpMyAdmin:

sudo ln -s /usr/share/phpmyadmin /var/www/html

Visit:

http://your-server-ip/phpmyadmin

Final Step: Reboot the Server

sudo reboot

Your Nginx, PHP 8.2, and MySQL web server is now fully set up on Ubuntu 22.04! 🚀
