Kibana 服务器未准备就绪

Question

我配置了 Elastic 搜索、Kibana 和日志存储集群。 弹性搜索工作正常，但 Kibana 显示错误，指出 Kibana 服务器未就绪。

日志显示

需要帮助！ 我也尝试删除

curl -XDELETE 'http://ElasticsarchIP:9200/.kibana_1' --header "content-type: application/JSON" -u elastic -p

Answer 1

首先，尝试删除版本化索引，然后按照上述建议重新启动：

curl -XDELETE http://localhost:9200/.kibana_1 

systemctl restart Kibana

如果它不起作用，请验证您已创建版本化索引，例如字节计数相同等。之后，删除原始的 .kibana：

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

然后为其别名：

curl -X POST "localhost:9200/_aliases" -H 'Content-Type: application/json' -d' { "actions" : [ { "add" : { "index" : ".kibana_1", "alias" : ".kibana" } } ] }'

然后重新启动 kibana。

Answer 2

我只是遵循了错误附带的建议：

如果没有其他 Kibana 实例正在尝试迁移，您可以过去 此消息通过删除索引.kibana_task_manager_1并重新启动 木花。

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

然后我重新启动了木花

Answer 3

这是由弹性搜索和 Kibana 之间的版本不匹配引起的，在设置弹性搜索和 Kibana 版本矩阵时使用以下版本 Elastic.co

https://www.elastic.co/support/matrix#matrix_compatibility

Answer 4

如果您不在乎丢失仪表板/可视化：

curl -XDELETE http://localhost:9200/.kibana*

这是唯一的解决方案，就像 elasticsearch 一样，如果没有快照，您永远无法恢复数据。

如果已经有.kibana_1索引，请检查.kibana别名是否也存在，或创建它：

curl -XPUT https://XXXXX/.kibana_1/_alias/.kibana

(任务管理器索引也是如此(。
