The following are installation instructions for the Nitrous.IO.
Step 1: Create a new application in boxes with NodeJS :
Step 2: Open terminal / SSH to the application / Open IDE
Step 3: Get the files of NodeBB, unzip, delete master.zip and cd to the folder
wget https://github.com/NodeBB/NodeBB/archive/v1.7.x.zip && unzip NodeBB-v1.7.x.zip && rm NodeBB-v1.7.x.zip && cd NodeBB-v1.7.x
Step 4: Install Redis
parts install redis
Step 5: Setup NodeBB
Leave everything as default but you can change yourself.
I recommend the port number to bind : 8080
Step 6: And the last one, start NodeBB
And then open the "Preview URI" without port if you have put for port : 8080.
