Kibana 服务器尚未准备好甚至启动

我有1个主节点（master）和1个数据节点（node-1）。 我使用centos7作为操作系统。

主控：9200

[root@localhost kibana]# curl localhost:9200
{
  "name" : "master",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "P4QlwvuRRGSmlT77RroSjA",
  "version" : {
    "number" : "7.6.1",
    "build_flavor" : "default",
    "build_type" : "rpm",
    "build_hash" : "aa751e09be0a5072e8570670309b1f12348f023b",
    "build_date" : "2020-02-29T00:15:25.529771Z",
    "build_snapshot" : false,
    "lucene_version" : "8.4.0",
    "minimum_wire_compatibility_version" : "6.8.0",
    "minimum_index_compatibility_version" : "6.0.0-beta1"
  },
  "tagline" : "You Know, for Search"
}

节点 1:9200

[root@dev ~]# curl localhost:9200
{
  "name" : "node-1",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "P4QlwvuRRGSmlT77RroSjA",
  "version" : {
    "number" : "7.6.1",
    "build_flavor" : "default",
    "build_type" : "rpm",
    "build_hash" : "aa751e09be0a5072e8570670309b1f12348f023b",
    "build_date" : "2020-02-29T00:15:25.529771Z",
    "build_snapshot" : false,
    "lucene_version" : "8.4.0",
    "minimum_wire_compatibility_version" : "6.8.0",
    "minimum_index_compatibility_version" : "6.0.0-beta1"
  },
  "tagline" : "You Know, for Search"
}

两个节点都可以看到对方

[root@localhost kibana]# curl master:9200/_cluster/health?pretty
{
  "cluster_name" : "elasticsearch",
  "status" : "yellow",
  "timed_out" : false,
  "number_of_nodes" : 2,
  "number_of_data_nodes" : 2,
  "active_primary_shards" : 27,
  "active_shards" : 27,
  "relocating_shards" : 0,
  "initializing_shards" : 0,
  "unassigned_shards" : 27,
  "delayed_unassigned_shards" : 0,
  "number_of_pending_tasks" : 0,
  "number_of_in_flight_fetch" : 0,
  "task_max_waiting_in_queue_millis" : 0,
  "active_shards_percent_as_number" : 50.0
}

kibana 安装在主节点上。 systemctl 状态 kibana。 更新了 kibana 日志

我们如何知道 kibana 和 elastic 之间的兼容版本？我查过matrix https://www.elastic.co/support/matrix它没有显示什么kibana版本支持什么elastic版本 任何形式的回应将不胜感激。先感谢您

答案就在最后一个 Kibana 日志行中。

此版本的 Kibana (v7.7.0) 与集群中的以下 Elasticsearch 节点不兼容：v7.6.1

您运行的是 ES 7.6.1 和 Kibana 7.7.0，这是行不通的。两者需要处于同一版本。
