第5章 起動と終了

5.1. 起動

Armadillo-IoT G3に電源を接続するときUSBシリアル変換アダプタのスライドスイッチによって起動モードが変わります。 詳しくは「スライドスイッチの設定について」を参照してください。 本節では、保守モードに設定しているときの例を示します。 オートブートモードを選択した場合は、途中でコマンドを入力することなく起動が完了します。

図5.2 起動ログ


[ティップ]

Armadillo-IoTの起動状態をユーザーLEDから確認することができます。このため、Armadillo-IoTにUSBシリアル変換アダプタを接続せずに電源を投入した場合でも、Linuxの起動を確認することができます。

起動状態ユーザーLED1ユーザーLED2ユーザーLED3ユーザーLED4
ブートローダーが保守モード点灯消灯消灯消灯
Linuxの起動中点灯点灯消灯消灯
Linuxが起動完了点灯消灯消灯消灯

ユーザーLEDの位置については、図6.35「ユーザーLEDの位置」を参照してください。

5.2. ログイン

起動が完了するとログインプロンプトが表示されます。表5.1「シリアルコンソールログイン時のユーザ名とパスワード」に示すユーザでログインすることができます。

表5.1 シリアルコンソールログイン時のユーザ名とパスワード

ユーザ名パスワード権限
rootrootrootユーザ
atmarkatmark一般ユーザ

初めて機器を接続したときは、必ず以下の手順に従って、初期パスワードを変更してください。

  1. rootでログイン

    初期パスワードを変更します。

    [armadillo ~]# passwd
    Enter new UNIX password: # 新しいパスワードを入力
    Retype new UNIX password: # 再入力
  2. atmarkでログイン

    初期パスワードを変更します。

    [armadillo ~]$ passwd
    Enter new UNIX password: # 新しいパスワードを入力
    Retype new UNIX password: # 再入力
    [armadillo ~]$ 
[警告]

Armadillo-IoT G3はネットワークに接続されることを前提としている機器ですので、 初期パスワードのままご利用になるとセキュリティリスクが非常に高まります。 セキュリティ強度の高いパスワードに変更され、その後も適切にパスワードを運用されることを強くお勧めします。

5.3. debianのユーザを管理する

  1. ユーザを作成

    例としてguestというユーザを作成します。

    [armadillo ~]# adduser guest
    Adding user `[user_name]' ...
    Adding new group `guest' (1001) ...
    Adding new user `guest' (1001) with group `guest' ...
    Creating home directory `/home/guest' ...
    Copying files from `/etc/skel' ...
    Enter new UNIX password: # パスワードを入力
    Retype new UNIX password: # 再入力
    passwd: password updated successfully
    Changing the user information for guest
    Enter the new value, or press ENTER for the default
            Full Name []: # Enterを入力
            Room Number []: # Enterを入力
            Work Phone []: # Enterを入力
            Home Phone []: # Enterを入力
            Other []: # Enterを入力
    Is the information correct? [Y/n] # Enterを入力
  2. パスワードの変更

    例としてguestユーザのパスワードを変更します。

    [armadillo ~]# passwd guest
    Enter new UNIX password: # 新しいパスワードを入力
    Retype new UNIX password: # 再入力
  3. sudoを許可する

    例としてguestユーザにsudoを許可します。viの使い方については、「viエディタの使用方法」を参照にしてください。

    [armadillo ~]# visudo
    ...
    # User privilege specification
    root    ALL=(ALL:ALL) ALL
    guest   ALL=(ALL:ALL) ALL # この行を追加します
    ...
  4. ユーザを削除

    例としてguestユーザを削除します。

    [armadillo ~]# userdel guest
    [ティップ]

    ホームディレクトリも合わせて消したいときは、"r"オプションをつけます。

    [armadillo ~]# userdel -r guest

5.4. 終了方法

安全に終了させる場合は、次のようにコマンドを実行し、「System halted.」と表示されたのを確認してから電源を切断します。
