Pi Zero cluster setup.

README.md

A bit of a Pi Zero cluster setup I'm getting together, with some setup notes in case I have to rebuild it.

Four Pi Zero's connected to a Pi 2, which is connected to the network via Ethernet or Wifi.

The below script should leave the Pi Zero's mounted to verify things.

pizero-clustersetup.sh

#!/bin/bash

c=1
for i in d e f g; do
        mkdir pi-$i
        mount /dev/sd${i}2 pi-$i
        mount /dev/sd${i}1 pi-$i/boot
        echo " " > pi-$i/boot/ssh
        echo -e "\ndtoverlay=dwc2" >> pi-$i/boot/config.txt
        mv pi-$i/boot/cmdline.txt pi-$i/boot/cmdline.txt.old
        sed  's/$/ modules-load=dwc2,g_ether/' pi-$i/boot/cmdline.txt.old > pi-$
        echo "pinode$c" >> pi-$i/etc/hostname
        mv pi-$i/etc/hosts pi-$i/etc/hosts.old
        sed "s/raspberrypi/pinode$c/" pi-$i/etc/hosts.old > pi-$i/etc/hosts

        c=$(( c+1 ))
done
