Setting up a new (headless) RPi.md

How to set up a "Headless" Raspberry Pi with my typical configurations (and preferred tools).

Goal: To put all of my infrquently used setups stuff in one place. Tested on: A Pi2 B (arm6l) with a fresh Raspbian Buster OS

Setup the OS, connections, and logins

• Download an OS image to another machine (currently Raspbian Buster Lite)
• Unzip the image
• Write the image to an SD card using Etcher.io
• If it will connect via WiFi, add a wpa_supplicant.conf to the /boot partition. Source: https://www.raspberrypi.org/documentation/configuration/wireless/headless.md
• Turn on ssh by placing a file called ssh in the boot partition.
• Insert the SD Card into the RPi and start it up.
• Locate the IP address (I used my router's info) and ssh in.
  • Default user: pi
  • Default pass: raspberry
• Change the default password: passwd
• Make a place for my cert: nano ./ssh/known_hosts (for password-less logins)
• Change the hostname: sudo nano /etc/hostname

Mount USB Drives

Get a sense of what is attached and device numbers, UUIDs, etc.

• cat /var/log/messages | tail -n 50 #Review the most recent 50 messages to see the details on what was plugged in.
• df # Which device has /boot? Don't want to mess with that one.
• lsusb # List USB devices with manufactuer's name/label
• ls -l /dev/disk/by-uuid/ # By UUID and device.
• ls -l /dev/disk/by-id # By name/label and device.

Mount it temporarily (manually)

• Create a directory for the mount point

sudo mkdir /media/usb32g
sudo mount /dev/sda1 /media/usb32g/ -o uid=pi,gid=pi

sudo mkdir /media/other_usb
sudo mount /dev/sdb1 /media/other_usb/ -o uid=pi,gid=pi

Format it:

sudo mkfs -t vfat -I /dev/sda1 (Not sure I really want vfat, but I’ll live with it for now).

Mount it permaently:

• sudo nano /etc/fstab

Set up Python 3

• Check python versions, install Conda (see other gist)
• Install pip3: sudo apt-get install python3-pip (not included in "lite" version)
• Install numpy dependency: sudo apt-get install libatlas-base-dev Source: numpy/numpy#11110
• Install python packages: pip3 install numpy pandas boto jupyterlab docker-compose

Install Docker Tools

• Install docker: sudo apt-get install docker.io
• Create a docker group and add the pi user to it: sudo usermod -aG docker pi #That way we don't need to use sudo all the time. Source: https://howchoo.com/g/nmrlzmq1ymn/how-to-install-docker-on-your-raspberry-pi
• Install docker-compose: pip3 install docker-compose
• Install docker-compose: sudo apt-get install docker-compose # Untested.

Set up boto/AWS

• Set up boto/AWS credentials: ``
