sudo設定

visudo という専用コマンドがあるので、それで /etc/sudoers を編集する。 ただし、そのまま実行すると (debianデフォルトの)nano エディタが起動してゲンナリするので、 先に環境変数を設定しておく。

$ declare -x EDITOR="vi"

・編集

$ visudo
	⇒「ユーザ名   ALL=(ALL) ALL」を追加

・反映

$ /etc/init.d/sudo
	Usage: /etc/init.d/sudo {start|stop|restart|force-reload}
$ /etc/init.d/sudo restart
