Cognitiveはよいぞ。電波伝搬はよいぞ。

ベアメタルサーバにRancherOSをインストールする手順(といくつか気づいたこと)。

おことわり:私と同じRancherOSを触ったことない人向けに書いているので、全体的に冗長な構成になっている。

tl;dr

  • 作業用Windowsから対象サーバーに対してRancherOSをインストールするまでの手順
  • RancherOSはいいぞ
  • RancherとRancherOSは別物だぞ。RancherOSはAlpine+Dockerみたいなもの。

モチベーション

  • ふくばねてすでつよつよだと取り上げられていた
  • 前々から@inductorさんが推してて気になってた
  • RancherOS環境に移行することで嫌でもDockerで作業をしなければならない状態を強制できる
  • 軽そう

環境

  • インストール先
  • インストール準備環境

前準備

この辺りを先に読んでおくと良い。

ファイルの準備

https://github.com/rancher/os/releases/ よりISOファイルをダウンロード

  • rancheros.isoを選ぶこと
    • 今回は2019/04/09時点で最新のv1.5.1を使用する

rufusで起動ディスク作成

RancherOSの手順には載っていないが、 https://rufus.ie/ を使用してISOからブータブルUSBを作成する。

f:id:kitkatayama:20190409222539p:plainf:id:kitkatayama:20190409222543p:plainf:id:kitkatayama:20190409222808p:plain
いくつか警告が出るが無視してかまわない

ベアメタルサーバーへインストール

USBディスクブート

rufusで作成したブータブルUSBを接続してサーバーを起動する。USBディスクが正常に読み込まれ、Linuxカーネルに対応したサーバーであれば、rancherユーザで自動的にログインされる。

BIOS設定によって内蔵ディスクのほうが起動優先度が高い場合がある。その際はBIOSから設定変更すること。(以下の図では、PRIMERGY TX1310 M1でのブートデバイスを指定する例を挙げている。)

f:id:kitkatayama:20190409222813p:plainf:id:kitkatayama:20190409223646j:plainf:id:kitkatayama:20190409223653j:plainf:id:kitkatayama:20190409223702j:plain
rebootからブータブルUSBからRancherOSが立ち上がるまで

SSHでのログイン

コンソール上のtty1では作業が面倒なので、一旦SSHで入れるようにする(この作業は、ブータブルUSBで起動している現在のセッションにのみ設定していることに留意する)。

sudo passwd rancher

f:id:kitkatayama:20190409223756j:plain
こればかりはコンソール上で実行が必要かもしれない。代替の方法があれば教えてほしい

Tips: sshd_configの追記について

sshd_configには、OpenSSHで生成されるデフォルトのものに比べ、以下の追記があるようにうかがえる。UseDNS noは、sshdの名前解決動作の関係でログインが遅くなることがあるのが知られているので、その解消のためと推測される。

UseDNS no
PermitRootLogin no

cloud-config.ymlの生成

手順によれば、GitHubの手順を参考に公開鍵認証用のキーペアを作成することが求められる。既に用意しているものがあればそれを使用しても良い。今回は、RancherOS用に新たなキーペアを生成することとする。

ここでcloud-config.ymlに記載した公開鍵は、rancherユーザの~/.ssh/authorized_keysに登録される。

キーペアの生成後、以下のコマンドでcloud-config.ymlを作成する。

echo -n -e "#cloud-config\nssh_authorized_keys:\n  - " > cloud-config.yml
echo "<生成した公開鍵>" >> cloud-config.yml

f:id:kitkatayama:20190409224023p:plain
手順通り、作業用のWindowsにてGit Bashで鍵を作成してみる

ディスクへの書き込み

念のため、ディスク一覧を確認後実行。

sudo ls /dev/sd*
sudo ros install -c cloud-config.yml -d /dev/sda

再起動確認されるので、再起動。尚、ブータブルUSBを接続したままにしていると、そちらが優先される可能性があるので注意すること。

f:id:kitkatayama:20190409224030p:plainf:id:kitkatayama:20190409224225j:plainf:id:kitkatayama:20190409224229j:plain
内蔵ディスクへの書き込み後、起動

Tips: rancher.password パラメータについて

rancher.password は、一時期、無効なパラメータとするように検討されていたようだ。

とはいえ、現在でも使用はデフォルトで可能である。セキュリティポリシー等でパスワードログインを無効にしたい場合は、こちらのドキュメントを参照して、カーネルから無効にすることができる。

再起動後、SSHログイン

公開鍵認証でrancherにログインできることを確認する。下記はTera Termの例。

f:id:kitkatayama:20190409224419p:plainf:id:kitkatayama:20190409224433p:plainf:id:kitkatayama:20190409224452p:plain
ブートデバイスが変更されたため、サーバー鍵が変更されていることに注意すること

その他

ネットワーク設定について

ここに書いてある。

https://rancher.com/docs/os/v1.2/en/networking/interfaces/

sudo ros config set rancher.network.interfaces.eth0.address 192.168.*.*/24
sudo ros config set rancher.network.interfaces.eth0.gateway 192.168.*.*
sudo ros config set rancher.network.interfaces.eth0.mtu 1500
sudo ros config set rancher.network.interfaces.eth0.dhcp false

設定が即時反映されるか不明だったため、念のため && で実行したが、これらの設定はreboot後に反映されるようだ。

RancherOS上で実行可能コマンドについて

RancherOSでは、全てDocker上でごにょごにょする思想となっている。とはいえ、ベースはLinuxなので、それなりのコマンドは使用できるようになっている。

$ echo $PATH
/bin:/sbin:/usr/bin:/usr/sbin

ところで、/bin/sbinを見ると、/usr/bin/usr/sbinシンボリックリンクされている。

[rancher@rancher ~]$ ls -al /bin /sbin
lrwxrwxrwx    1 root     root             7 Oct 25 18:43 /bin -> usr/bin
lrwxrwxrwx    1 root     root             8 Oct 25 18:43 /sbin -> usr/sbin

つまり、RancherOS v1.5.1で使えるコマンドは以下のようになっている。参考になれば幸い。
