Raspberry Pi

Basic setup

This assumes a headless install on a RPi.

  • Download and install raspberry imager

  • Run rpi-imager

  • Follow the instructions to put an OS image on your SD card. I installed Raspbian lite (no desktop).

  • Since I’m setting it up headless, there are a few more steps. headless instructions

    • Now mount the boot partition from the SD card (the smaller one). (e.g. insert SD card, run thunar or other file browser)

    • Create an empty file named ssh in the root of the boot partition.

    • If you need to connect now using wireless, create a wpa_supplicant.conf file in the root of the boot partition:

      ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
      country=<Insert country code here>
       ssid="<Name of your WiFi>"
       psk="<Password for your WiFi>"
    • Unmount

  • Put the SD card into the RPi.

  • If using wired ethernet, hook up the ethernet cable. If using a wifi dongle, insert it.

  • Plug in the power.

  • Wait a bit. Check your router admin to see what address it ended up at. On mine it came up as raspberrypi.mynet (.mynet is my local network domain).

  • ssh pi@raspberrypi.mynet. Password is raspberry.

  • Create a new user:

    sudo adduser poirier
  • Set a password:

    sudo passwd poirier
  • To enable sudo for the user, edit the sudoers file by running sudo visudo and add a line like poirier ALL=(ALL:ALL) NOPASSWD:ALL

  • Log out

  • ssh poirier@raspberrypi.mynet

  • Delete the old pi user:

    sudo deluser --remove-all-files pi
