RHEL9にPHP8.3系をインストールする

はじめに

Red Hat社が AWS 上で配布するコミュニティ AMI を使用し、
EC2 上に起動した Red Hat Enterprise Linux 9 の環境において、
デフォルト状態では PHP 8.0系がインストールされる状態にあります。

PHP 8.0系は 2023/11/26 で EOL を迎えており、今から導入することは推奨されません。
本記事では最新の8.3系を導入するには？について記載しています。

いきなりまとめ

PHP 8.2系および8.3系は remi リポジトリで提供がありますので、
subscription-manager を無効化した上で、Appstream を指定してインストールします。

# dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-9.noarch.rpm -y
# dnf install https://rpms.remirepo.net/enterprise/remi-release-9.rpm -y

# cat /etc/yum/pluginconf.d/subscription-manager.conf
[main]
enabled=0

# When following option is set to 1, then all repositories defined outside redhat.repo will be disabled
# every time subscription-manager plugin is triggered by dnf or yum
disable_system_repos=0

# dnf module install php:remi-8.3 -y
# php -v

EC2 インスタンス起動直後

本記事では RHEL 9.2 を使用します。

AMI名	AMI ID
RHEL-9.2.0_HVM-20230905-x86_64-38-Hourly2-GP2	ami-04fdeff70b7359022

$ cat /etc/redhat-release
Red Hat Enterprise Linux release 9.2 (Plow)

デフォルト状態での有効なリポジトリは Red Hat社が提供する BaseOS, AppStream および
rhui-client-config-server-9 があります。

# dnf repolist

利用可能な PHP バージョンを確認すると 8.1系の提供がありました。

特に何も考えずに PHP をインストールすると、AppStream リポジトリ経由で　8.0.30 が入るようです。

ただ、8.1系は本記事を書いている段階で EOL を迎えるまで1年を切っており、
2024/11/25 でサポートが終了となります。

2024/8/7 追記
本日確認したところ、PHP 8.1系の EOL (セキュリティサポート)が、2025/12/31 まで延長されております。

引き続き、以下では8.2系もしくは8.3系をインストールする方法を確認します。
Supported Versions

EPEL, remiリポジトリ追加

Appstream リポジトリでは現状PHP 8.1系の提供になるため、EPEL, remi リポジトリを追加します。

# dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-9.noarch.rpm -y
# dnf install https://rpms.remirepo.net/enterprise/remi-release-9.rpm -y

両リポジトリを追加した後、8.2系および8.3系がインストール可能になります。

subscription-manager 無効化

EPEL や Remi リポジトリ経由でパッケージのインストールを試みると、
subscription-manager でサブスクリプション登録を促すメッセージが表示されます。

# dnf module install php:remi-8.3 -y

Dependencies resolved.
The operation would result in switching of module 'php' stream '8.1' to stream 'remi-8.3'
Error: It is not possible to switch enabled streams of a module unless explicitly enabled via configuration option module_stream_switch.
It is recommended to rather remove all installed content from the module, and reset the module using 'dnf module reset ' command. After you reset the module, you can install the other stream.

実際には RHEL AMI には、アップデートやメンテナンスによる修正を受けるための
基本サブスクリプションが含まれており、subscription-manager に登録する必要はありません。

subscription-manager はデフォルト状態で enabled=1 (有効) になっているので enabled=0 (無効) にします。

# cat /etc/yum/pluginconf.d/subscription-manager.conf
[main]
enabled=0

# When following option is set to 1, then all repositories defined outside redhat.repo will be disabled
# every time subscription-manager plugin is triggered by dnf or yum
disable_system_repos=0

PHP 8.3系のインストール

以下の通り、晴れて8.3系をインストールすることができました。

# dnf module install php:remi-8.3 -y
