Raspberry Pi Cluster

Cluster Tutorial

Hardware Setup

• Rpi v1 x1
• Rpi v3 x2

Master Node Setup

sudo raspi-config
# change the hostname to indicate master node
sudo apt update && sudo apt upgrade
sudo apt install vim isc-dhcp-server

touch ssh
touch wpa_supplicant.conf

country=us
update_config=1
ctrl_interface=/var/run/wpa_supplicant

network={
 scan_ssid=1
 ssid="MyNetworkSSID"
 psk="Pa55w0rd1234"
}

Installing DHCP server software for master node

1. Edit dhcpd.conf

    PUT comment tag # in front of option domain-name "example.org";
    PUT comment tag # in front of option domain-name-servers ns1.example.org, ns2.example.org;
    REMOVE the comment tag # in the line #authoritative;
   

2. subnet 192.168.8.0 netmask 255.255.255.0 {
     range 192.168.8.100 192.168.8.200;
     option broadcast-address 192.168.8.255;
     option routers 192.168.8.1;
     max-lease-time 7200;
     option domain-name "rpi3";
     option domain-name-servers 8.8.8.8, 8.8.4.4;
   }
