kibana启动后访问失败 curl: (52) Empty reply from server

问题：

想构建一个单机ES+Kibana做测试，安装最新版本（8.17.0）ES和Kibana的rpm包，修改配置文件并启动ES和Kibana，ES正常访问，Kibana始终无法访问，使用curl命令测试返回结果

[root@16- ~]# curl 127.0.0.1:5601 -I
curl: (52) Empty reply from server

发现：

部署的单机ES，基本访问测试正常

[root@16- ~]# curl 127.0.0.1:9200
{
  "name" : "node1",
  "cluster_name" : "singlenode-cluster",
  "cluster_uuid" : "_na_",
  "version" : {
    "number" : "8.17.0",
    "build_flavor" : "default",
    "build_type" : "rpm",
    "build_hash" : "2b6a7fed44faa321997703718f07ee0420804b41",
    "build_date" : "2024-12-11T12:08:05.663969764Z",
    "build_snapshot" : false,
    "lucene_version" : "9.12.0",
    "minimum_wire_compatibility_version" : "7.17.0",
    "minimum_index_compatibility_version" : "7.0.0"
  },
  "tagline" : "You Know, for Search"
}

集群健康访问报错

[root@16- ~]# curl -XGET 'localhost:9200/_cluster/health?pretty'
{
  "error" : {
    "root_cause" : [
      {
        "type" : "master_not_discovered_exception",
        "reason" : null
      }
    ],
    "type" : "master_not_discovered_exception",
    "reason" : null
  },
  "status" : 503
}

解决

ES的配置中新增了集群master配置

discovery.seed_hosts: ["192.168.100.16"]
cluster.initial_master_nodes: ["192.168.100.16"]
