One-Click Ghost Install Script for Ubuntu and CentOS
One-Click Ghost Install Script for Ubuntu and CentOS - installGhost.sh

I had to modify the script to point to the most current version which also works on CentOS:

wget -O - https://gist.githubusercontent.com/pengpengliu/d9a77df1b1d823528d42/raw/a41a2afdea11017d7572bdb143792c44f0cbc567/installGhost.sh | sudo bash

FastComet provides nice instructions for using this script:

I will test this soon and post my results here.

Shared Hosting for Ghost

For an even more simple Ghost hosting solution that gives you a full (shared) hosting package with a cPanel interface, a drop-dead simple (and cheap) web host which I use is FastComet. This Ghost site is running on FastComet. (It's fast, right?)
