How I update Ghost blogging platform
First login to your server. Well really the first thing should be to make a backup of your blog but I'm way too lazy for that!
ssh yourserver.com wget http://ghost.org/zip/ghost-latest.zip sudo su - cd /path/to/your/ghost/install
Stop ghost from running using whatever method you setup. For me I use an init script
/etc/rc.d/init.d/ghost stop rm -fr core unzip -uo /path/to/downloaded/file/ghost-latest.zip -d /path/to/your/ghost/install npm install --production /etc/rc.d/init.d/ghost start
Boom you're done. To confirm just login to the admin portal for your ghost blog and go to 'About'
