Red Hat Enterprise Linux 8 の Developer サブスクリプション更新

Red Hat Developer サブスクリプションの更新【Red Hat Enterprise Linux for x86_64】

RHEL の Developer サブスクリプションが切れていたので、更新のメモ。
今回はホスト名変えたからなのか、 SSL 証明書のエラーも発生中。

[root@rhel-m01 ~]# subscription-manager status
Unknown server reply (HTTP error code 400: Bad Request):
<html><13>
<head><title>400 The SSL certificate error</title></head><13>

RHEL のサポート情報より、プロファイルの ID 再生成を実施(詳細は参考URL)
