x-packをインストールするとelasticsearchが実行されなくなる

CentOS VMゲストon Win10ホスト。 x-packの場合はinstallation guideに従うように試みます（そしてtraining courseからステップバイステップ）。 ESとKは正常に動作しますが、x-packプラグインがインストールされると、キバナが起動します（ESが見つからないと訴えます）。 3と同じエラーが発生しますが、プロダクション設定ではなくローカルVMで表示されます。x-packをインストールするとelasticsearchが実行されなくなる

さてここでログの末尾ですログには

が含まれているため

Caused by: java.nio.file.AccessDeniedException:

問題はおそらくユーザーのアクセス許可です。このディレクトリの所有者は誰ですか？

/etc/elasticsearch/x-pack

ls -l /etc/elasticsearch/x-packから出力するものは何ですか？

sudo権限を持っているか、root権限を持っている場合は、このディレクトリの所有権を変更するだけです。

ありがとう！これは確実な一歩でした。 system_keyファイルは '-rw -------でした。 1 root root 128 Dec 9 16:29 system_key'だからchmod 604ファイルに少なくとも弾力性のための読み取り権を取得し、サービスを開始することができました。既定のユーザーアカウントはまだログインしていませんが、適切なアクセス許可をさらに見直してください。これは確かに主な問題を解決するのに役立ちました。 –

それは鍵であるので、 'sudo chown elastic：elastic system.key'を使って所有権を弾力的に変更する方が良いです。ほとんどのセキュリティプログラムは、権限セットをチェックします。私は他人に読書のアクセスを与えないことを勧めます。これはあなたのために働くはずです。 HTH – cinhtau

が理解され、検証されます。 chmodは問題領域を証明することでした...しかし、「ローカルリダイレクトが多すぎます」ので、より多くのノードがトラブルシューティングできるようにプラットフォームを変更する必要があります。 –

はそれを試してみる：

オープンのconfig/elasticsearch.ymlファイル
変更xpack構成行

xpack.security.enabled: false xpack.graph.enabled: false xpack.watcher.enabled: false

問題は、elasitcsearchとx-packのインストールに使用したユーザーアカウントの問題です。同じアカウントを使用し、正しい権限を持っていることを確認してください！

chownを使用してアクセスを許可したい場合があります。
