安裝x-pack會停止運行彈性搜索

Win10主機上的Centos VM guest虛擬機。試圖按照installation guide進行x-pack（並從training course開始逐步執行）。 ES和K運行良好，但是一旦安裝了x-pack插件，kibana將啓動（並且抱怨ES丟失 - 這很好），然後彈性搜索開始並立即失敗。它看起來像3一樣的錯誤，但在本地虛擬機中，而不是生產設置。這裏的日誌尾部：安裝x-pack會停止運行彈性搜索

好因爲日誌包含

Caused by: java.nio.file.AccessDeniedException:

問題可能是用戶權限。這個目錄的所有者是誰？

/etc/elasticsearch/x-pack

ls -l /etc/elasticsearch/x-pack給你什麼輸出？

如果您具有sudo權限或具有root用戶訪問權限，則可以更改此目錄的所有權。

謝謝！這是肯定的一步。 system_key文件是：-rw -------。 1 root root 128 Dec 9 16:29 system_key' so chmod 604 on the file to get read rights for elastic，and the service was able to start。默認的用戶帳戶尚未登錄，但生病進一步審查正確的權限。這當然有助於解決主要問題 –

由於這是一個關鍵，最好使用'sudo chown elastic：elastic system.key'將所有權更改爲彈性。大多數安全程序檢查權限集。我會建議不要給別人一個閱讀權限。這應該適合你。 HTH – cinhtau

瞭解，並會驗證。 chmod是爲了證明問題所在......然而，現在有了'太多的本地重定向'，因此可能需要更改我的平臺以允許更多節點進行故障排除。 –

嘗試一下：

打開配置/ elasticsearch.yml文件
變化xpack配置行

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

問題在於您用來安裝elasitcsearch和x-pack的用戶帳戶。確保您使用相同的帳戶並擁有正確的權限來執行此操作！

您可能想要使用chown授予訪問權限。
