WordPressのヘルスチェック項目で、PHPのバージョンが古いと怒られた。CentOS6から8へやっとサーバ移行したばかりだというのに・・・
# dnf module list php
CentOS Linux 8 - AppStream
Name Stream Profiles Summary
php 7.2 [d][e] 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 あら・・・デフォルトの7.2のままだったorz
remiとか使わずに7.4をインストールできるのなら最初から入れておけば良かったけれど、気づいていなかったんだなぁ
といってもdnfかつ標準リポジトリしか使っていないのでこのような時の対応は非常に簡単。
# dnf module install php:7.4
Dependencies resolved.
The operation would result in switching of module 'php' stream '7.2' to stream '7.4'
Error: It is not possible to switch enabled streams of a module.
It is recommended to remove all installed content from the module, and reset the module using 'dnf module reset <module_name>' command. After you reset the module, you can install the other stream.
あ、怒られた。最初にphpモジュールを削除しておかないとダメなのね
# dnf module remove php
Unable to match profile in argument php
Dependencies resolved.
Nothing to do.

Complete!php7.4だけをdnfでインストールしましたが、7.2の細かいモジュールも全て自動的にアップグレードされました。
念のために # systemctl restart php-fpm だけ実行しておいて、Wordpressのヘルスチェックも問題が解消されました。もちろんコンテンツの表示も問題なし！
