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

手順7: Webサーバ設定
手順7-1: httpdインストール
httpdをインストールします。
Oracle Linux 9.2ではWebサーバとして Apache(httpd) 2.4.53 、nginx 1.20.1、nginx 1.22.1が使えるが、apacheを使う。
$ sudo dnf install httpd -y

手順14 メモリが足らない対策
Oracle CloudのFree Tierで初期値のまま稼働させてみたのですが、頻繁に応答がなくなりました。(Oracle Linux 8だと問題なかったんだけど、Oracle Linux 9だと1日複数回発生)
