テクニカルサポートの 片方 です。
今回は、RHEL9 OS の EC2 インスタンスに nkf をインストールする機会があったのでご紹介します。
やってみた
検証として、RHEL-9.6.0_HVM-20250618-x86_64-0-Hourly2-GP3 (ami-040573aabcd4f9b69) を利用しました。
- EPELリポジトリのインストール
$ sudo dnf install -y https://dl.fedoraproject.org/pub/epel/epel-release-latest-9.noarch.rpm
- DNF設定ツールのインストール
$ sudo dnf install -y dnf-utils
- CodeReady Builder (CRB) リポジトリの有効化
$ sudo dnf config-manager --set-enabled codeready-builder-for-rhel-9-rhui-rpms
- リポジトリが正しく有効化されたことを確認
※ 出力に codeready-builder-for-rhel-9-rhui-rpms が含まれていることを確認します。
$ sudo dnf repolist
- nkfのインストール
$ sudo dnf install -y nkf
- インストールの確認
$ nkf --version
※ 検証環境で実施した際のコマンド実行例です。
