# Configurazione Raspberry Pi da riga di comando
|
||||
|
||||
Scaricare la ISO da [https://www.raspberrypi.com/software/operating-systems/](https://www.raspberrypi.com/software/operating-systems/)
|
||||
|
||||
```bash
|
||||
cd ~/Scaricati
|
||||
wget -c https://downloads.raspberrypi.org/raspios_lite_arm64/images/raspios_lite_arm64-2023-02-22/2023-02-21-raspios-bullseye-arm64-lite.img.xz
|
||||
```
|
||||
|
||||
Quindi decomprimere l'archivio:
|
||||
|
||||
```bash
|
||||
xz -d 2023-02-21-raspios-bullseye-arm64-lite.img.xz
|
||||
```
|
||||
## Flashare il SO sulla microSD
|
||||
|
||||
Tramite il comando `lsblk -f` individuare il device corretto.
|
||||
|
||||
Quindi smontare il device. Una volta smontato procedere a:
|
||||
|
||||
- creare una nuova tabella gpt;
|
||||
- creare una nuova partizione;
|
||||
- formattare la partizione nel file-system `ext4`;
|
||||
- flashare la iso tramite `dd`:
|
||||
|
||||
```bash
|
||||
sudo lsblk -f
|
||||
NAME FSTYPE FSVER LABEL UUID FSAVAIL FSUSE% MOUNTPOINTS
|
||||
sda
|
||||
├─sda1 vfat FAT32 bootfs 37CA-39EC
|
||||
└─sda2 ext4 1.0 rootfs a4af13c6-d165-4cbd-a9f6-c961fef8255d 344,9M 73% /media/davide/rootfs
|
||||
|
||||
umount /dev/sda1
|
||||
umount /dev/sda2
|
||||
|
||||
sudo fdisk /dev/sda
|
||||
Comando (m per richiamare la guida): g
|
||||
Created a new GPT disklabel (GUID: CE1B9100-FFF7-0041-9C6F-34080C8A08C6).
|
||||
Comando (m per richiamare la guida): n
|
||||
Numero della partizione (1-128, default 1):
|
||||
First sector (2048-124805086, default 2048):
|
||||
Last sector, +/-sectors or +/-size{K,M,G,T,P} (2048-124805086, default 124803071):
|
||||
Created a new partition 1 of type 'Linux filesystem' and of size 59,5 GiB.
|
||||
Comando (m per richiamare la guida): w
|
||||
The partition table has been altered.
|
||||
Calling ioctl() to re-read partition table.
|
||||
Syncing disks.
|
||||
|
||||
sudo mkfs.ext4 /dev/sda1
|
||||
mke2fs 1.47.0 (5-Feb-2023)
|
||||
Creating filesystem with 15600128 4k blocks and 3907584 inodes
|
||||
Filesystem UUID: ab33b6d8-fdf0-44b5-977d-3511ee17c9ed
|
||||
Superblock backups stored on blocks:
|
||||
32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208,
|
||||
4096000, 7962624, 11239424
|
||||
|
||||
Allocating group tables: done
|
||||
Writing inode tables: done
|
||||
Creating journal (65536 blocks): done
|
||||
Writing superblocks and filesystem accounting information: done
|
||||
|
||||
umount /dev/sda1
|
||||
|
||||
dd if=2023-02-21-raspios-bullseye-arm64-lite.img of=/dev/sda status=progress
|
||||
|
||||
sudo lsblk
|
||||
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS
|
||||
sda 8:0 1 59,5G 0 disk
|
||||
├─sda1 8:1 1 256M 0 part /media/davide/bootfs
|
||||
└─sda2 8:2 1 1,7G 0 part /media/davide/rootfs
|
||||
```
|
||||
In questo modo si otterranno le due partizioni seguenti:
|
||||
|
||||
```bash
|
||||
sudo lsblk -f
|
||||
|
||||
NAME FSTYPE FSVER LABEL UUID FSAVAIL FSUSE% MOUNTPOINTS
|
||||
sda
|
||||
├─sda1 vfat FAT32 bootfs 37CA-39EC 224,4M 12% /media/davide/bootfs
|
||||
└─sda2 ext4 1.0 rootfs a4af13c6-d165-4cbd-a9f6-c961fef8255d 344,9M 73% /media/davide/rootfs
|
||||
```
|
||||
|
||||
## Configurazione della rete wireless
|
||||
|
||||
```bash
|
||||
cd /media/davide/bootfs/
|
||||
|
||||
cat wpa_supplicant.conf
|
||||
|
||||
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
|
||||
country=IT
|
||||
update_config=1
|
||||
|
||||
network={
|
||||
ssid="<name>"
|
||||
psk="***********"
|
||||
}
|
||||
```
|
||||
|
||||
## Configurazione utente
|
||||
|
||||
```bash
|
||||
cat userconf.txt
|
||||
|
||||
davide:$6$Nf4LCWz7u2fcO4Vs$Z2S/T6IjgLXWTAWZfmWUbnraE0haKD0O7tt43ytGC3O7sN14UDOOGeZ7RDHOUxUZlqOOq54Ry2eAVcNfnRbiX.
|
||||
```
|
||||
Per generare la password crittografata dare il comando:
|
||||
|
||||
```bash
|
||||
openssl passwd -6
|
||||
```
|
||||
|
||||
## Configurazione ssh
|
||||
|
||||
Creare in `bootfs` il file `.sh` e appendere `net.ifnames=0` nel file `cmdline.txt`
|
||||
|
||||
```bash
|
||||
cat cmdline.txt
|
||||
|
||||
console=serial0,115200 console=tty1 root=PARTUUID=e088fd39-02 rootfstype=ext4 fsck.repair=yes rootwait quiet init=/usr/lib/raspberrypi-sys-mods/firstboot net.ifnames=0
|
||||
```
|
||||
## Impostare indirizzo IP statico
|
||||
|
||||
```bash
|
||||
cd /media/davide/rootfs/
|
||||
cd etc/
|
||||
tail -n 5 dhcpcd.conf
|
||||
|
||||
interface wlan0
|
||||
static ip_address=192.168.1.100/24
|
||||
static routers=192.168.1.1
|
||||
static domain_name_servers=5.2.75.75
|
||||
```
|
||||
|
||||
## Cambiare hostname
|
||||
|
||||
Nella medesima directory, modificare il nome host nei due seguenti file:
|
||||
|
||||
```bash
|
||||
cat hostname
|
||||
|
||||
pi
|
||||
|
||||
cat hosts
|
||||
|
||||
127.0.0.1 localhost
|
||||
::1 localhost ip6-localhost ip6-loopback
|
||||
ff02::1 ip6-allnodes
|
||||
ff02::2 ip6-allrouters
|
||||
|
||||
127.0.1.1 pi
|
||||
```
