rhel8試用に伴う Red Hat サブスクリプションの有効化

Red Hat Enterprise Linux 8 を試用しますが、今後もきっと、忘れるので、メモ

rhel8の初期状態では、repositoryを参照できず、yum を使用できません

$ cat /etc/redhat-release 
Red Hat Enterprise Linux release 8.4 (Ootpa)

$ sudo yum install samba

Updating Subscription Management repositories.
Unable to read consumer identity

This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.

Error: There are no enabled repositories in "/etc/yum.repos.d", "/etc/yum/repos.d", "/etc/distro.repos.d".

以下のコマンドにより、Red Hat の サブスクリプション & repository の有効化

ブラウザで redhatへ、アクセスすることでも可能なようですが、試していません
