Prerequisites

1. Your Compute Engine Instance running with minimum 1 GB RAM.

Install Nginx

Ghost uses Nginx web server, you can start updating the packages and install Nginx. SSH to your VM Instance and execute the following commands

sudo apt update
sudo apt upgrade

sudo apt install nginx

Once Nginx is installed proceed to configure and enable UFW.

sudo ufw allow OpenSSH
sudo ufw allow 'Nginx HTTP'
sudo ufw allow 'Nginx HTTPS'
sudo ufw enable

Install Node.js

To install Ghost you need a supported Node.js version, so you can use the officially recommended Node.js v10.

curl -sL https://deb.nodesource.com/setup_10.x | sudo -E bash -
sudo apt install -y nodejs

Confirm the Node.js and NPM installation with the following commands.

node -v
npm -v

You will get the installed version number.

Install Ghost-CLI

You can use the official ghost-cli to setup MySQL user and database and configure Nginx as reverse proxy and finally secure the site with Let’s Encrypt SSL certificate.

sudo npm install ghost-cli@latest -g

Install Ghost

Once your server is setup and ghost-cli is installed you can install Ghost.

Note: Installing Ghost in /root or home/ directories results in a broken setup. Use a custom directory with properly configured permissions.

sudo mkdir /var/www/ghost
