RasPi設定まとめ

Raspiのupdate

$ sudo rpi-updateで実行

その後$ sudo rebootで再起動

rootのパスワード設定

pi@raspberrypi:~ $ sudo passwd root
Enter new UNIX password:
Retype new UNIX password:
passwd: password updated successfully

root userでログインできるか確認

pi@raspberrypi:~ $ su
Password:
root@raspberrypi:/home/pi# exit

pi userのパスワード設定

pi@raspberrypi:~ $ sudo passwd pi
Enter new UNIX password:
Retype new UNIX password:
passwd: password updated successfully

user (sampleUser)加える

pi@raspberrypi:~ $ sudo adduser sampleUser
Adding user `sampleUser' ...
Adding new group `sampleUser' (1001) ...
Adding new user `sampleUser' (1001) with group `sampleUser' ...
Creating home directory `/home/sampleUser' ...
Copying files from `/etc/skel' ...
Enter new UNIX password:
Retype new UNIX password:
passwd: password updated successfully
Changing the user information for sampleUser
Enter the new value, or press ENTER for the default
    Full Name []: < 空白でOK
    Room Number []:
    Work Phone []:

piと同様の権限をsampleUserに渡す

まずpiがどの権限を持ってるのか確認

pi@raspberrypi:~ $ groups pi
pi : pi adm dialout cdrom sudo audio video plugdev games users input netdev spi i2c gpio

この権限をsampleUserに渡し、最後に$ groups sampleUserで権限確認

pi@raspberrypi:~ $ sudo usermod -G pi,adm,dialout,cdrom,sudo,audio,video,plugdev,games,users,netdev,input,spi,gpio sampleUser

SSH KeyをRasPiに渡す

Terminal 2つ [Local]と[Raspi]開きましょう (keygenミスったりすると入れなくなります)

1. Keyを作成

[local]$ ssh-keygen -t rsaにより~/.ssh/id_rsaにpublic keyとprivate key作成される

2. KeyをRaspi側に移す

[local]$ scp id_rsa.pub yourRasPiAddr:~/.sshpublic Keyを移動

3. public Keyをauthorized_keysに書き出す

[Raspi]@raspberrypi:~/.ssh $ cat id_rsa.pub >> authorized_keys
[Raspi]@raspberrypi:~/.ssh $ ls -a
.  ..  authorized_key  id_rsa.pub

4. 権限設定

[Raspi]@raspberrypi:~/.ssh $ chmod 600 authorized_key
[Raspi]@raspberrypi:~ $ chmod 700 .ssh
[Raspi]@raspberrypi:~/.ssh $ su
Password:
root@raspberrypi:/home/[Raspi]/.ssh# cd /etc/ssh

5. デーモン書き換え

root@raspberrypi:/etc/ssh# vim sshd_config

以下のファイル書き換え

AuthorizedKeysFile      %h/.ssh/authorized_keys
PasswordAuthentication no
PermitRootLogin no

6. デーモン再起動

[Raspi]@raspberrypi:~/.ssh $ sudo /etc/init.d/ssh restart
[ ok ] Restarting ssh (via systemctl): ssh.service.
