I decided to have a look around for an alternative to WordPress. I must admit I do have a tendency to do this from time to time. Anyway, enter Ghost. No php, just pure js built for the new world order. Anyway, get your Raspberry Pi up and running with Raspbian Jessie and then plug in the following commands - you can check through the here for the latest v4 (Argon) nodejs. That is currently the best supported version Ghost recommends.

cd ~
wget http://nodejs.org/dist/latest-argon/node-v4.6.2.tar.gz
tar -xzf node node-v4.6.2.tar.gz
cd node-v4.6.2
./configure
make
sudo make install
node -v

cd ~
curl -L https://ghost.org/zip/ghost-latest.zip -o ghost.zip
sudo unzip -uo ghost.zip -d /var/www/[your-web-site]
cd /var/www/[your-web-site]
sudo npm install --unsafe-perm --production
sudo nano config.js

Under production
        url: 'http://[your-webserver-address]',

Under server
            host: '0.0.0.0',
            port: '80'

sudo npm start --production
