# Move Adminer to the web server directory
echo "Moving Adminer to /var/www/html/..."
sudo mv adminer.php /var/www/html/
# Set correct ownership and permissions
echo "Setting ownership and permissions for Adminer..."
sudo chown www-data:www-data /var/www/html/adminer.php
sudo chmod 644 /var/www/html/adminer.php
# Enable PHP module and restart Apache
echo "Enabling PHP module and restarting Apache..."
sudo a2enmod php
sudo systemctl restart apache2
echo "Adminer installation and configuration complete. Access it at http://<your-server-ip>/adminer.php"
2. Make the Script Executable
