Setup Raspberry Pi

Image

Download Images

If using new version Raspbian, make sure all the version related name in fabfile.py is matched

Write Image into SD Card

  1. Select image.zip
  2. Select drive
  3. Flash!

Configuration

Setup SSH

In order to connect to Raspberry Pi without a monitor at first. We need to enable ssh since in current version of Raspbian it is default disable.

  1. Create a empty file called ssh at the root directory of the SD card.
    • touch /Volumes/boot/ssh
  2. Ejact (Unmount) SD card
    • Check the device name of the SD Card diskutil list
    • Unmount disk diskutil unmountDisk /dev/diskNum

Connect to Pi

Scan Pi's IP Address

There are many approaches

nmap

Use ifconfig and see current PC WLAN address and replace x with related value

  • nmap -sn 192.168.x.x/24

Fing

Angry IP Scanner

SSH Client

  • Windows
    • putty
  • iOS, Android
    • Terminus

Connection

Default setting

  • user: pi
  • password: raspberry

e.g. ssh [email protected]

Additional Settings

raspi-config

Login to each Raspparry Pi and type sudo raspi-config (only for Raspbian)

  1. Setup locale

Format and copy image from another SD card
