echo "LAMP, WordPress, Let's Encrypt, virtual host, and optimization setup is complete!"Save the above script in a file (e.g., setup.sh), make it executable using chmod +x setup.sh, and then execute it with ./setup.sh. The script will guide you through the setup process, prompting you to enter your domain name and perform the necessary installations and configurations.
Please note that running a script like this should be done with caution, as it will make changes to your system configuration. Ensure you have backups and review the script to make any necessary modifications to fit your specific requirements.
