elasticsearch - Kibana 无法在 Windows 上连接到 elasticsearch

Question

我正在运行 Elastic Search 7.6，它在 http://localhost:9200/ 上运行正常。我能够使用 REST API 将值添加到索引。

现在，当我启动 kibana 7.6 时，出现以下错误:-

log   [12:31:32.247] [info][plugins-service] Plugin "case" is disabled.

Unable to connect to Elasticsearch. Error: Request Timeout after 30000ms

我遇到了和你一样的问题，我通过将 cmd 提示符 窗口切换到 PowerShell 窗口解决了这个问题。看来命令提示符窗口非常敏感。您可能会在这里得到一些想法。 https://discuss.elastic.co/t/kibana-7-4-0-on-windows-command-prompt-not-able-to-start/203877/7

顺便说一句，如果您在重新启动 Kibana 时收到警告，例如:

  log   [06:27:47.136] [warning][savedobjects-service] Unable to connect to Elasticsearch. Error: [resource_already_exists_exception] index [.kibana_task_manager_1/EmPx77s1TLWbLQdqQ8iC0w] already exists, with { index_uuid="EmPx77s1TLWbLQdqQ8iC0w" & index=".kibana_task_manager_1" }
  log   [06:27:47.140] [warning][savedobjects-service] Another Kibana instance appears to be migrating the index. Waiting for that migration to complete. If no other Kibana instance is attempting migrations, you can get past this message by deleting index .kibana_task_manager_1 and restarting Kibana.

只需按照它告诉您的操作，删除索引 .kibana_task_manager_1 并重新启动 Kibana。

curl -XDELETE http://localhost:9200/.kibana_task_manager_1

祝你好运。
