MEAN Setup

new_gist_file_0

For my purposes I didn't use build dist because there was some confusion retrieving assets and such so I just stuck to development and kept things in the client folder
From there:
Use the FTP client of your choice to upload your angular-fullstack folder to /opt
In the terminal of your choice run: ssh root@your-digital-ocean-ip-address
cd into /opt/name-of-your-fullstack-project-folder
Then run node server/app.js
This will start up your server in development on port 9000.

To keep the server running:
Run these commands in order
In server/config/production.js change port from 8080 to 80
npm install forever -g 
export NODE_ENV='production'
cd back into /opt/name-of-your-fullstack-project-folder
forever start server/app.js

You may already know many of these steps but I detailed it pretty much step by step to avoid any confusion, hope it helps!
