起動用 SD カードの作成

Raspberry Pi Imager で簡単作成 (Windows/macOS/Ubuntu)

Use Raspberry Pi Imager for an easy way to install Raspberry Pi OS and other operating systems to an SD card ready to use with your Raspberry Pi:

GUI でお好きなイメージを。

初回起動時 SSH 有効化

私の環境では、 /Volumes/boot が SD カードの root です。
空の ssh ファイルを作成。

~ ❯❯❯ cd /Volumes/boot
/V/boot ❯❯❯ touch ssh
/V/boot ❯❯❯ ls -la ssh
-rwxrwxrwx  1 user1  staff  0 Sep 25 11:04 ssh

初回起動時 Wi-Fi 有効化

wpa_supplicant.conf に Wi-Fi の情報を記載。

/V/boot ❯❯❯ touch wpa_supplicant.conf
/V/boot ❯❯❯ vi wpa_supplicant.conf
/V/boot ❯❯❯ cat ./wpa_supplicant.conf
country=JP
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
network={
    ssid="Your-SSID"
    psk="your-password"
}

SD カードを raspberry pi に挿入し、電源 ON

SSH 確認

Raspberry Pi の wifi の mac address を事前に確認しておくといいかも。 私は DHCP でアドレス配布しているルータから mac address で IP address を逆引きします。

Router#show ip dhcp binding | i 01dc.a632

Raspberry Pi OS のデフォルトクレデンシャルは pi/raspberry

The default user is pi, and the password is raspberry. You can add users and change each user's password.

SSH is enabled and the default password for the 'pi' user has not been changed.
This is a security risk - please login as the 'pi' user and type 'passwd' to set a new password.
