Agenda
• Hardware requirements
• Software requirements
• Install Raspbian
• Additional configuration of Raspbian
• Setup external HDD
• Setup Samba Server

3.
Hardware requirements
• Raspberry Pi 4 Computer Modell B, 1GB RAM
• Adapter cable from micro HDMI (Type D) to HDMI (Type A)
• official Raspberry Pi USB-C power supply 5,1V / 3,0A
• piece heat sink set for Raspberry Pi 4
• microSDHC 32GB
• SEAGATE Expansion Portable, 5TB HDD, 2.5 Zoll, extern
• PC with card reader
• USB Keyboard for Raspberry Pi

4.
Software requirements
• Raspian Buster Lite
We don't need a desktop for a server, so the Lite version is a good choice.
• balenaEtcher
Flash OS images to SD cards & USB drives

5.
Install Raspbian
• Download Raspian Buster Lite
Link: https://downloads.raspberrypi.org/raspbian_lite_latest
• Download balenaEtcher
Link: https://www.balena.io/etcher/
• flash Raspian Buster Lite image to sd card

card-make-bootable-usb

6.
Install Raspbian
• Connect your Raspberry pi with your monitor, network (LAN) and keyboard
• Insert the SD card into the raspberry pi
• Connect the power supply and watch the output on the monitor.
• First the SD card is prepared, and a restart is required.
• Log in with the login pi and password raspberry.
NOTE: On a german keyboard z and y are swapped!
• For remote access you must activate ssh manually with follows commands
sudo systemctl enable ssh
sudo systemctl start ssh

7.
Install Raspbian
• Shutdown your raspberry pi with
sudo poweroff
• You can now remotely access the Raspberry Pi using SSH.
• Disconnect your monitor and keyboard from raspberry pi
• Startup your raspberry pi

8.
Additional configuration of Raspbian
• Start a terminal on your computer and execute the following command:
ssh pi@<ip-address>
• You still have to change other configurations such as password. Use
command:
sudo raspi-config
• Checklist:
• Change hostname
• Change password
• Change your keyboard settings

9.
Setup external HDD
• Setup and use the LogicalVolume Manager (LVM)
sudo apt-get install lvm2
• Connect your external HDD to USB 3 Port (blue) and wait for a moment
• With the following command you should see your drive.
sudo lsblk –f

10.
Setup external HDD
• Hard disk is set up with LVM.
PV_DEV="/dev/sda2“
sudo umount "${PV_DEV}“
sudo pvcreate "${PV_DEV}“
VG_NAME="vhd1“
sudo vgcreate "${VG_NAME}" "${PV_DEV}“
sudo vgdisplay

11.
Setup external HDD
LV_NAME="backup-var“
VG_NAME="$(sudo vgdisplay
| sudo grep "VG Name"
| sudo head --lines=1
| sudo cut --characters=25-)“
sudo lvcreate -n "${LV_NAME}" -l100%FREE "${VG_NAME}“
sudo mkfs -t ext4 "/dev/${VG_NAME}/${LV_NAME}“
sudo mkdir /media/backup-var
Based on https://howto.biapy.com/en/debian-gnu-linux/system/setup/setup-and-use-the-logical-volume-manager-lvm-on-debian

12.
Setup external HDD
sudo blkid | grep vhd1-backup--var
open file with
sudo nano /etc/fstab
and insert this line at the end.
UUID=f843cba9-8aec-4dd7-831d-7383ea49bd1d
/media/backup-var ext4 defaults 0 0
Based on https://howto.biapy.com/en/debian-gnu-linux/system/setup/setup-and-use-the-logical-volume-manager-lvm-on-debian

13.
Setup Samba Server
• Install Samba Server
sudo apt-get update
sudo apt-get install samba samba-common smbclient
• Check Samba Server
sudo service smbd status
sudo service nmbd status
• Basic configuration of the Samba server
sudo mv /etc/samba/smb.conf /etc/samba/smb.conf_old
sudo nano /etc/samba/smb.conf

14.
Setup Samba Server
• The Content of /etc/samba/smb.conf
[global]
workgroup = WORKGROUP
security = user
encrypt passwords = yes
client min protocol = SMB2
client max protocol = SMB3

15.
Setup Samba Server
• Check configuration with
testparm
If you see the following messages, then you should still execute this here.
Open config file with:
sudo nano /etc/security/limits.conf
And add at the end
* - nofile 16384
root - nofile 16384
reboot your raspberry pi

16.
Setup Samba Server
• Create a folder for samba share:
sudo mkdir /media/backup-var/backup
sudo chown root:root /media/backup-var/backup
sudo chmod 777 /media/backup-var/backup
• Open smb.conf
sudo nano /etc/samba/smb.conf
• Add this at end
[backup]
comment = Samba-Backup-Share
path = /media/backup-var/backup
read only = no

17.
Setup Samba Server
• Close file and check this file with
testparm
• Restart Samba Server with:
sudo service smbd restart
sudo service nmbd restart

18.
Setup Samba Server
• Add user to linux and Samba Server
sudo useradd -M pi-share
sudo smbpasswd -a pi-share
• open yourWindows Explorer and visit
nas-01backup
<ip-address>backup

19.
Setup Samba Server
At this point you have a simple Windows
share installed on the Raspberry Pi.
