Oracle Cloud外の環境でOracle Linux 8をインストールしている場合や古めのOracle Cloudインスタンスの場合、こちらのOS側のコマンドで設定する手順を行います。
現状のレポジトリ設定状況を「sudo dnf repolist –all」を実行して確認します。

手順3-1b:Oracle CloudのOS管理下にある場合の手順
2022年4月6日時点でOracle Cloud上で提供されているOracle-Linux-8.5-aarch64-2022.03.17-1では「sudo dnf repolist –all」の実行結果に変化があり、「This system is receiving updates from OSMS server.」と書かれた上で、だいぶ整理されたレポジトリのみが表示されます。

Oracle Linux 8環境では、moduleという形で複数バージョンのソフトウェアが提供されています。
phpに関してどのようなものがあるのかを「dnf module list | grep php」を実行して確認します。
$ sudo dnf module list | grep php
php 7.2 [d] common [d], devel, minimal PHP scripting language
php 7.3 common [d], devel, minimal PHP scripting language
php 7.4 common [d], devel, minimal PHP scripting language
$
php 7.2が標準選択で、他にphp 7.3とphp 7.4が選べることがわかります。 2022/07/01時点で提供されているOracle Linux 8.6では php 8.0も選択できるようになっています。
php7.4を指定してパッケージを追加します。
$ sudo dnf install @php:7.4 -y

手順6: MySQL設定編
Oralce Linux 8ではわざわざ「MySQL 8.0 for Oracle Linux 8 (aarch64)」を用意していますが、よく見るとそこにmysql-serverはなく、メインのol8_appstream に含まれているという理由はよくわかりませんが、せっかくなのでそのまま使用します。
MySQL 8におけるデータベースユーザ作成と権限の割り当てが従来の「grant all on DB名.* to wordpress@localhost identified by ‘パスワード’;」という一文から、「create user ～」と「grant ～」の２つに分かれている点に注意が必要です。
$ sudo mysql -u root
