elasticsearch - Kibana服务器尚未准备好

Question

我刚刚在RHEL 8上安装了Kibana 7.3。Kibana服务处于 Activity 状态(正在运行)。
当我 curl 到http://localhost:5601时，我收到Kibana server is not ready yet消息。
我的Elasticsearch实例在另一台服务器上，并且成功响应了我的请求。我已经更新了kibana.yml

elasticsearch.hosts:["http://EXTERNAL-IP-ADDRESS-OF-ES:9200"]

我可以通过响应从互联网访问elasticsearch:

{
  "name" : "ip-172-31-21-240.ec2.internal",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "y4UjlddiQimGRh29TVZoeA",
  "version" : {
    "number" : "7.3.1",
    "build_flavor" : "default",
    "build_type" : "rpm",
    "build_hash" : "4749ba6",
    "build_date" : "2019-08-19T20:19:25.651794Z",
    "build_snapshot" : false,
    "lucene_version" : "8.1.0",
    "minimum_wire_compatibility_version" : "6.8.0",
    "minimum_index_compatibility_version" : "6.0.0-beta1"
  },
  "tagline" : "You Know, for Search"
}

sudo systemctl status kibana的结果:

the result of "sudo journalctl --unit kibana"

您知道问题出在哪里吗？

Answer 1

当我将Elasticsearch从6.x升级到7.x时，我曾经遇到过同样的问题。

删除.kibana*索引可解决此问题。
