RHEL 7 yumコマンドがエラーで使えない

9月 29, 2022AmazonLinux_CentOS,OperatingSystem

概要

  • EC2 上に起動したRHEL(Red Hat Enterprise Linux) 7 の環境において、yumコマンドを実行すると下記の様なエラーとなり、yumコマンドが使用できません。
  • 原因は、rh-amazon-rhui-client が 2.x 以下だとリポジトリにアクセスできないことが原因のようです。

  • rpmコマンドで rh-amazon-rhui-client のバージョンを確認します。以下の様に、2.x 以下だと該当します。
$ rpm -qa rh-amazon-rhui-client
rh-amazon-rhui-client-2.2.117-1.el7.noarch
$ rpm -qa rh-amazon-rhui-client
rh-amazon-rhui-client-2.2.133-1.el7.noarch

 

対処方法

  • RHEL7.9 の AMI (例: ami-0155fdd0956a0c7a0) を使用して、新規にインスタンスを起動します。自力で、RHEL のAMIを探すのは労力が掛かります。
  • yumdownloader rh-amazon-rhui-client コマンドを使用して、rh-amazon-rhui-clientの最新RPM モジュールを取得します。念のため、rh-amazon-rhui-client のバージョンが 3.x 以降であることを確認します。

  • インストール対象のインスタンスに、scpコマンドやS3 経由でファイルを送ります。
  • rpm -U コマンドでrh-amazon-rhui-client を更新します。
$ sudo rpm -Uvh ./rh-amazon-rhui-client-4.0.4-1.el7.noarch.rpm
