Installatie Raspberry Pi

1 – RASPBERRY PI 3 B+ HEADLESS SETUP (SSH and WiFI) 

Write Image to SD Card with Etcher

Enable SSH by placing a file named “ssh” (without any extension) onto the boot partition of the SD card:

Add “wpa_supplicant.conf” File to the SD Card Root with the following text

country=NL
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1

network={
    ssid="EDH-WAP-002-2.4GHz-Open-Internet"
    psk="NETWORK-PASSWORD"
}

Boot your Pi AND CHANGE YOUR PASSWORD

2 -For security add a new user and Remove the default user the PI

Check the current PI groups

groups

pi adm dialout cdrom sudo audio video plugdev games users input netdev gpio i2c spi

Add a new user with the same groups

sudo useradd -m -G adm,dialout,cdrom,sudo,audio,video,plugdev,games,users,input,netdev,gpio,i2c,spi USERNAME

Give the new user a password

sudo passwd USERNAME

sudo nano /etc/passwd

USERNAME:x:1001:1001::/home/USERNAME:/bin/bash

Reboot and login with new username and remove the default user PI

sudo deluser --remove-all-files pi

3 – Raspberry Pi updaten

sudo apt-get update -y && sudo apt-get upgrade -y

4 – Static IP address

sudo nano /etc/dhcpcd.conf

To use DHCP disable the appropiate lines by placing a # in front of the line.

5 – Hostname
sudo hostname name
