Amazon Linux 2023とAmazon Linux2のデフォルトで起動しているサービスやインストールされているパッケージに違いがあるか気になるな

こんにちは、のんピ(@non____97)です。

Amazon Linux 2023がGAされましたね。

こちらの記事でも紹介した通り、Amazon Linux 2023とAmazon Linux 2とを比較して、リポジトリに追加・削除されたパッケージが相当数あります。

どのパッケージが追加・削除されたかはAWS公式ドキュメントから判断つきますが、どのサービスがデフォルトで起動していて、どのパッケージがインストールされているかの情報はありません。

気になったのでAmazon Linux 2023とAmazon Linux2のデフォルトで起動しているサービスやインストールされているパッケージを比較してみます。

検証で使用するAMIは以下の通りです。

  • Amazon Linux 2 : amzn2-ami-kernel-5.10-hvm-2.0.20230307.0-x86_64-gp2(ami-005f9685cb30f234b)
  • Amazon Linux 2023 : al2023-ami-2023.0.20230315.0-kernel-6.1-x86_64(ami-02f3f602d23f1659d)

いきなりまとめ

  • Amazon Linux 2023を使う場合はどのようなパッケージがインストールされているか把握しよう
  • 個人的に気になるAmazon Linux 2023にインストールされていないパッケージは以下
    • rsyslog
    • cronie
    • iptables
    • make
    • lvm2

特に気になるのはcrond.serviceとrsyslog.serviceがAmazon Linux 2023ではデフォルトではインストールされていないことでしょうか。

rsyslog がインストールされていない問題

rsyslog.serviceについてはFedora 20でデフォルトでインストールされなくなったようです。

これはAmazon Linux 2023はFedora 34, 35, 36をベースにしているので、Amazon Linux 2023でもインストールされていないようです。なお、標準リポジトリで提供はされているためインストールすることは可能です。

# rsyslogがインストールされているか確認

「ログが確認できなくて困る」と思われるかもしれません。しかし、journalが出力されているため、journalctlで確認することができます。

また、journalはデフォルトで/var/log/journal配下に出力しているようですね。

journalctlだと全てのユニットやkernelなどのログが出力されます。その場合は、各種オプションを指定してあげます。

これによりsystemdに出力されるログはjournalctlで確認ができます。

journalctlの詳細は以下マニュアルをご覧ください。

2023/3/21時点ではCloudWatch Agentを使ってjournalをCloudWatch Logsに転送することはできません。

そのため、「/var/log/messagesに特定メッセージが出力されたら、CloudWatch LogsのサブスクリプションフィルターでLambda関数を使って通知する」といったことはできません。

jouranalをFluent Bitを使ってCloudWatch Logsに出力している猛者もいますが、素直にrsyslogをインストールさせた方が良い気もします。

journalの設定は以下の通りです。

全てコメントアウトされているためデフォルトのようですね。

デフォルトだとSystem journal(/var/log/journal)の最大使用量は10%(上限 4GB)なので、journalでがディスクが溢れるということは少なそうです。

各設定値の詳細な説明を以下マニュアルをご覧ください。

Cron がインストールされていない問題

crond.serviceは存在していません。

$ systemctl status crond
Unit crond.service could not be found.

Fedoraのドキュメントを確認すると、cronieというパッケージをインストールすることでCronが使えるようです。

確認してみると確かに標準リポジトリ上にcronieがありました。

$ dnf info cronie

Description  : Cronie contains the standard UNIX daemon crond that runs specified programs at
             : scheduled times and related tools. It is a fork of the original vixie-cron and
             : has security and configuration enhancements like the ability to use pam and
             : SELinux.

Cronを使いたい場合は、上述のFedoraのドキュメントを参考にcronieをインストールして、crond.serviceの起動と自動起動を有効化すれば良さそうですね。

Cronを使わずに定期実行を行いたい場合は、systemdのtimerを設定することでも対応できます。

試しに10秒ごとにecho testをするtimerを設定します。

約10秒毎にecho testが実行されていますね。

正確に10秒毎に実行したい場合はtimerの精度AccuracySecを100msなど小さい値にするなど調整をしてください。ただし、小さい値にするとCPU負荷に影響があると考えます。

serviceとtimerの2つのファイルを作成する必要がありますが、[Timer]でかなり自由にスケジューリングすることができます。

systemd.timerとsystemd.timeの詳細は以下マニュアルをご覧ください。

ec2-net-utils.noarchがamazon-ec2-net-utils.noarchとパッケージ名が変わったり、cloud-utils-growpart.noarchがcloud-utils-growpart.x86_64とアーキテクチャーの指定が入ったりと、完全に異なるパッケージの差分となってはいないのでご注意ください。

AWS CLIがv2になっているのがありがたいですね。

また、気になるところとしてはiptablesがインストールされていないようです。OS上でフィルタリングしたい場合はnftablesを使うと良いでしょう。

makeもAmazon Linux 2023にインストールされていないためソースファイルをコンパイルしたい場合は事前にmakeをインストールする必要があります。

EC2インスタンス上でLVMを使うことも少ないと思いますが、LVMを使う場合はlvm2をインストールしてください。

Amazon Linux 2023を使う場合はどのようなパッケージがインストールされているか把握しよう

Amazon Linux 2023とAmazon Linux2のデフォルトで起動しているサービスやインストールされているパッケージを比較してみました。

かなり差分があるのでAmazon Linux 2023を使う場合はどのようなパッケージがインストールされているか、サービスが起動しているのか事前に把握しておきましょう。

この記事が誰かの助けになれば幸いです。
