Kibana服务器还没有准备好，甚至没有开始。

Question

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

主节点: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"
}

双节点互见

[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 status kibana.update log on kibana。

我们怎么知道kibana和elastic之间的兼容版本？ 我查过了 矩阵 It did not show what kibana version support what elastic versionAny kind of respond will be appreciated so much.thank you in advance.

Answer 1

答案就在最后的Kibana日志行中。

这个版本的Kibana(v7.7.0)与你的集群中的以下Elasticsearch节点不兼容：v7.6.1。

你运行的是ES 7.6.1和Kibana 7.7.0，那就不行了。两者需要在同一个版本上。
