NetBackup™ for Cassandra 管理者ガイド

プライマリサーバーでの cassandra.conf ファイルの設定

Cassandra クラスタを保護するには、Cassandra クラスタの構成の詳細を含むプライマリサーバーに構成ファイルを作成する必要があります。次のパスで作成します。

cassandra.conf ファイルのサンプル:

CBR ノードの RSA キーを入力します。RSA キーを取得するには、データステージングサーバーで使用するホストクレデンシャルを使用して CBR ノードにログインし、cat /etc/ssh/ssh_host_rsa_key.pub |awk '{print $2}' |base64 -d |sha256sum |awk '{print $1}' コマンドを実行します。
