Raspbian Stretch Liteのセットアップ

Raspbian Raspberry Pi Linux

次回インストール時に困らないためのメモ

SDカードの準備

  1. Download Raspbian for Raspberry Piから落としたイメージをbalenaEtcherで焼く。
  2. /boot/sshを作る。
  3. /boot/wpa_supplicant.confにWifi設定を書き込む。

/boot/wpa_supplicant.conf

country=JP
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
network={
  ssid="foo"
  psk=bar
}
network={
  ssid="baz"
  psk=qux
  priority=1
}

本編

ssh pi@raspberrypi.localで繋がる。デフォルトのパスワードはraspberry
適当なタイミングでssh-keygen -t ed25519してGitHubに登録しておく。
