Raspberry Pi Setup Guide

1. Share Mac's Ethernet port [via]
2. Determine PI IP Address arp -a
3. ssh pi@192.168.2.2 / raspberry
4. Generate SSH keys [via]
5. SSH key auth scp ~/.ssh/id_rsa.pub pi@192.168.2.2:~/.ssh/authorized_keys
6. change pi password
7. sudo raspi-config "update this tool to latest version"
8. set TZ, locale (disable en_GB)
9. set hostname to a pi-pun
10. sudo apt-get update
11. sudo apt-get install git-core
12. sudo apt-get install ruby

X11 Notes

• may want to set X11 to full screen mode in Preferences
• ssh -Y pi@192.168.2.2 to get an X11 Forward ssh session [via]
• lxsession starts Desktop Manager
• can start other X apps from cmd line without running Desktop Manager

Deployment Ideas

• Dokku - a mini heroku in bash
• mislav/git-deploy

Copying the public ssh key file can be done with scp ~/.ssh/id_rsa.pub pi@192.168.2.2:~/.ssh/authorized_keys as well.

@nbenes, OSX is inexplicably missing is ssh-copy-id, but good catch. Updated.

The reason I used that one above was that I was kinda fascinated that you can pipe into a remotely executed command. cat ~/.ssh/id_rsa.pub | ssh pi@192.168.2.2 "cat >> ~/.ssh/authorized_keys"

Trying to run dashboard start i had this error: Could not find a JavaScript runtime?
but i solved it with installing NodeJS sudo apt-get install nodejs
Also i had to install RVM for Ruby 2.0
