CentOS 9には公式リポジトリでPHP 7.4がサポートされていないため、Remiリポジトリを使用してPHP 7.4をインストールする必要があります。以下の手順に従ってインストールを行います。
ステップ 1: 依存パッケージのインストール
まず、必要な依存パッケージをインストールします。ターミナルで以下のコマンドを実行してください:
sudo dnf install epel-release -y
sudo dnf install dnf-utils -y画面ログ：

ステップ 2: Remiリポジトリのインストール
Remiリポジトリは、複数のPHPバージョンを提供しているサードパーティのリポジトリです。以下のコマンドでRemiリポジトリをインストールします:
sudo dnf install https://rpms.remirepo.net/enterprise/remi-release-9.rpm -y[root@localhost ~]# sudo dnf install https://rpms.remirepo.net/enterprise/remi-release-9.rpm -y Updating Subscription Management repositories.

Installed: remi-release-9.4-2.el9.remi.noarch Complete!
ステップ 3: Remiリポジトリを有効化し、PHP 7.4を選択
次に、PHP 7.4のモジュールを有効化する必要があります。まず、利用可能なPHPモジュールをリストします:
sudo dnf module list php[root@localhost ~]# sudo dnf module list php Updating Subscription Management repositories. Unable to read consumer identity This system is not registered with an entitlement server. You can use "rhc" or "subscription-manager" to register. Remi's Modular repository for Enterprise Linux 9 - x86_64 256 kB/s | 680 kB 0 Safe Remi's RPM repository for Enterprise Linux 9 - x86_64 365 kB/s | 1.0 MB 0 Last metadata expiration check: 0:00:01 ago on Tue 10 Sep 2024 12:58:10 PM JST.

表示されたリストから「PHP 7.4」を確認し、以下のコマンドで有効化します:
sudo dnf module enable php:remi-7.4 -y[root@localhost ~]# sudo dnf module enable php:remi-7.4 -y Updating Subscription Management repositories. Unable to read consumer identity This system is not registered with an entitlement server. You can use "rhc" or "subscription-manager" to register.

Dependencies resolved. ==================================================================================================================================================================================== Package Architecture Version Repository ==================================================================================================================================================================================== Enabling module streams: php remi-7.4 Transaction Summary ==================================================================================================================================================================================== Complete!
ステップ 4: PHP 7.4のインストール
Remiリポジトリを有効にした後、以下のコマンドでPHP 7.4とその関連パッケージをインストールします:
sudo dnf install php php-cli php-common php-mysqlnd php-fpm php-json php-xml php-mbstring php-zip php-gd php-curl -yThis system is not registered with an entitlement server. You can use "rhc" or "subscription-manager" to register. Last metadata expiration check: 0:00:41 ago on Tue 10 Sep 2024 12:58:10 PM JST. Dependencies resolved. ==================================================================================================================================================================================== Package Architecture Version Repository ==================================================================================================================================================================================== Installing: php x86_64 7.4.33-17.el9.remi remi-modular php-cli x86_64 7.4.33-17.el9.remi remi-modular php-common x86_64 7.4.33-17.el9.remi remi-modular php-fpm x86_64 7.4.33-17.el9.remi remi-modular php-gd x86_64 7.4.33-17.el9.remi remi-modular php-json x86_64 7.4.33-17.el9.remi remi-modular php-mbstring x86_64 7.4.33-17.el9.remi remi-modular php-mysqlnd x86_64 7.4.33-17.el9.remi remi-modular php-pecl-zip x86_64 1.22.3-1.el9.remi.7.4 remi-modular php-xml x86_64 7.4.33-17.el9.remi remi-modular Installing dependencies: gd3php x86_64 2.3.3-9.el9.remi remi-safe highway x86_64 1.2.0-2.el9 epel libaom x86_64 3.9.0-1.el9 epel libavif x86_64 0.11.1-4.el9 epel libdav1d x86_64 1.2.1-1.el9 epel libimagequant x86_64 2.17.0-1.el9 epel libjxl x86_64 0.7.0-1.el9 epel libraqm x86_64 0.8.0-1.el9 epel libsodium x86_64 1.0.18-8.el9 epel libvmaf x86_64 2.3.0-2.el9 epel oniguruma5php x86_64 6.9.9-1.el9.remi remi-safe php-pdo x86_64 7.4.33-17.el9.remi remi-modular ...
ステップ 5: PHPのバージョンを確認
インストールが完了したら、以下のコマンドでPHPのバージョンを確認できます:
php -v「PHP 7.4」が表示されれば、インストールは正常に完了しています。
[root@localhost html]# php -v
PHP 7.4.33 (cli) (built: Aug 26 2024 13:25:54) ( NTS )
Copyright (c) The PHP Group
Zend Engine v3.4.0, Copyright (c) Zend Technologies
with Zend OPcache v7.4.33, Copyright (c), by Zend Technologies
ステップ 6: PHP-FPMの起動と有効化
Webサーバー（NginxやApache）とPHPを連携させるためにPHP-FPMを使用する場合、以下のコマンドでPHP-FPMを起動および有効化します:
sudo systemctl start php-fpm
sudo systemctl enable php-fpm[root@localhost html]# sudo systemctl enable php-fpm Created symlink /etc/systemd/system/multi-user.target.wants/php-fpm.service → /usr/lib/systemd/system/php-fpm.service.
以上の手順で、CentOS 9にPHP 7.4をインストールし、動作させることができます。NginxやApacheとの連携方法についても、別の記事で解説していますので、ご参考ください。
