Ghost is a free and open source blogging platform written in node.js, completely customizable and dedicated for publishing. For a manual install, read this tutorial.

The Script

The script is hosted on GitHub Gist. For a fully automated install, you will need the file install.sh. If you do not want to use an encrypted connection, then you will also need to replace https with http.

apt-get update
apt-get install wget -y

wget -O - https://gist.githubusercontent.com/bbs4us/58809c6ddbbbe960af9b/raw/phantom.sh | bash >> /tmp/phantom.log
sleep 5
wget -N https://gist.githubusercontent.com/bbs4us/58809c6ddbbbe960af9b/raw/ghostly.sh && bash ghostly.sh https yoursite.tld # replace me
sleep 1

Now you can create a new instance with the script. After installation, go to https://yoursite.tld/ghost/setup/ to setup user login credentials. You will see a warning about certificate not trusted, ignore that as the certificate is self-signed.
