无法将Kibana连接到Elasticsearch

我已经在RHEL7上安装了ES 7.5和Kibana 7.5，但是在启动Kibana并检查UI后，我看到了错误，“ Kibana服务器尚未准备好。”

检查Kibana日志，我发现它没有正确连接到ES。任何帮助表示赞赏！

这是 journalctl –unit kibana 的输出：

另外，当我运行 ss -tunlp | grep 5601_在Kibana启动期间，我看到Kibana服务正在 _5601

上监听。但是，在多次尝试自动连接到ES的过程中，它停止监听5601和 _ss -tunlp | grep 5601不_返回任何内容。

回答：

FATAL [mapper_parsing_exception] No handler for type [flattened]

使用Elastic non-OSS v7.3 +或Kibana OSS。

Kibana 7.5非OSS（基本）使用flattenedElasticsearch

7.3+的OSS版本中可用的类型。

OSS版本仅包含Apache 2.0许可下可用的功能-https:

//www.elastic.co/subscriptions

您可以使用GET _nodes以下命令进行检查：

{ "name" : "flattened", "version" : "7.5.0", "elasticsearch_version" : "7.5.0", "java_version" : "1.8", "description" : "Module for the flattened field type, which allows JSON objects to be flattened into a single field.", "classname" : "org.elasticsearch.xpack.flattened.FlattenedMapperPlugin", "extended_plugins" : [ "x-pack-core" ], "has_native_controller" : false },
