はじめに
- 本記事はOCIのコンピュート上で稼働しているOracle Linux 7.9をOracle Linux 8.9へアップグレードする手順です。また、カーネルのアップグレード(UEK R5からUEK U7へ)も行っています。
- 7.9から8.9へはleappでアップグレードできます。オンプレミス環境はもちろん、OCIにも正式に対応しています。
前提
- Computeは構築済み
- 利用するOS Imageは「Oracle-Linux-7.9-2022.05.31-0」LINK（2024年2月時点では7.9で一番古い）
手順概要
- Yum Update(色々更新
- leappのための前提条件確認
- leappをインストール
- leapp preupgrade
- leapp upgrade
- 事後処理
- カーネルアップデート
- dnf update(色々更新
手順記載していませんが、実際に行う前にはBoot Volumeのバックアップを行いましょう

2. leappのための前提条件確認
- こちらを確認（以下ピックアップしますが、詳細はドキュメントを確認ください）
-
OCIネイティブイメージはLeapp でアップグレード可能だが、BYOIなどはNG。
-
カーネルはUEK→UKEはOK。 RHCKからUEKや、その逆はNG。今回はOracle LinuxではデフォルトのUEK。
-
Btrfs 使っていると厳しい？
-
セキュア ブートが実行されている場合は無効化する
-
ロケールが en_US.UTF-8 に設定されていること
-
RootユーザによるSSHログインを許可する
-
OCIのOS管理が有効化されている場合、無効化する（OCIコンソールのGUIからプラグインを無効化）
- 以下のイメージ
- 以下のイメージ

Title: Missing required answers in the answer file
Summary: One or more sections in answerfile are missing user choices: remove_pam_pkcs11_module_check.confirm

日本語訳１

改善: [hint] leapp answer cliコマンドで、またはanswerfileを手動で編集して、ユーザーの選択肢を登録してください。
leapp answer --section remove_pam_pkcs11_module_check.confirm=True
抜粋２
Risk Factor: high
Title: Packages not signed by Oracle found on the system
Summary: The following packages have not been signed by Oracle and may be removed during the upgrade process in case Oracle-signed packages to be
removed during the upgrade depend on them:
- gpg-pubkey
- wlp-agent
日本語訳２
次のパッケージはOracleによって署名されておらず、アップグレード中に削除されるOracle署名付きパッケージがそれらに依存する場合に備えて、アップグレード・プロセス中に削除される可能性があります。
抜粋３
Risk Factor: high
Title: Difference in Python versions and support in OL 8
Summary: In OL 8, there is no 'python' command. Python 3 (backward incompatible) is the primary Python version and Python 2 is available with lim
ited support and limited set of packages. Read more here: https://docs.oracle.com/en/operating-systems/oracle-linux/8/python/
Remediation: [hint] Please run "alternatives --set python /usr/bin/python3" after upgrade
日本語訳３
OL 8では、'python'コマンドはありません。Python 3(後方互換性のない)はプライマリPythonバージョンであり、Python 2は制限付きサポートと限定されたパッケージセットで利用できます。続きを読む: https://docs.oracle.com/en/operating-systems/oracle-linux/8/python/改善: [hint]アップグレード後に
