# Installation
Download the latest Raspberry Pi OS, lite version, based on Debian bookworm:
```auto
$ wget https://downloads.raspberrypi.com/raspios_lite_armhf/images/raspios_lite_armhf-2024-11-19/2024-11-19-raspios-bookworm-armhf-lite.img.xz
```
Verify the integrity of the file:
```auto
$ wget https://downloads.raspberrypi.com/raspios_lite_armhf/images/raspios_lite_armhf-2024-11-19/2024-11-19-raspios-bookworm-armhf-lite.img.xz.sha256
$ echo "$(cat 2024-11-19-raspios-bookworm-armhf-lite.img.xz.sha256)" | sha256sum --check
```
Copy the image to an SD card:
```auto
$ unxz 2024-11-19-raspios-bookworm-armhf.img.xz
$ sudo dd if=2024-11-19-raspios-bookworm-armhf-lite.img of= bs=16M status=progress oflag=sync
```
Now put the SD card in the RaspberryPi, connect it to an HDMI monitor and a USB keyboard, and boot.
Enter keyboard layout, the user name and the password.
Login.
Enable ssh:
```auto
$ sudo systemctl enable ssh
```
Change the hostname:
```auto
$ sudo hostnamectl set-hostname tabechaka-05
```
Also edit the file `/etc/hosts` to replace `raspberrypi` with `tabechaka-05`.
Turn it off:
```auto
$ systemctl poweroff
```
Now I can move it to the rack and login with ssh.
Install software for administration:
```auto
$ sudo apt update
$ sudo apt install emacs-nox byobu
```
Enable ssh public key authentication:
```auto
$ mkdir --mode 700 ~/.ssh
```
Add my user public key to `~/.ssh/authorized_keys`.
Adjust the permission of this file.
```auto
$ chmod 600 .ssh/authorized_keys
```
Disable ssh password autentication:
Edit the file `/etc/ssh/sshd_config`, uncommenting and setting:
```auto
PasswordAuthentication no
```
```auto
$ sudo systemctl reload sshd
```
Reboot:
```auto
$ sudo systemctl reboot
```
