centosstream8 に nginx1.20 , php8.1 をインストール

centosstream9 だと snapdが入らずSSL化できない。
ということで 8 に落として再インストール

yum が dnf になった
以下、すべてrootで。

まずはバージョンを最新にしてselinuxをオフ

dnf update
sudo timedatectl set-timezone Asia/Tokyo
grubby --update-kernel ALL --args selinux=0
shutdown -r now

#epel 的なのを一気にインスコ

dnf -y install epel-release
dnf -y install elrepo-release
dnf -y install https://rpms.remirepo.net/enterprise/remi-release-8.rpm
dnf config-manager --set-enabled powertools
dnf install epel-release epel-next-release

#最新の nginx をインスコ

//ついでに自動起動設定も
sudo systemctl enable nginx
sudo systemctl enable php-fpm

これで、あなたのIPにアクセスしたときにphpinfoが表示されればOK!

必要に応じphp.iniも変更
