Ghost CMS Server Setup Script for Ubuntu

A comprehensive bash script that automates the setup of a Ghost CMS environment on Ubuntu servers. The script handles:

• Creating a new system user with sudo privileges
• System updates and package installation (nginx, MySQL)
• MySQL secure configuration
• Node.js installation with version selection
• Ghost CLI installation
• Directory preparation for Ghost installation

Usage:

./setup_ghost.sh --username [user] --user-password [password] --mysql-password [mysql_pwd] --nodejs-version [e.g. 18]

After running this script, you can proceed with the actual Ghost installation by using the 'ghost install' command.
