实验平台：CentOS Linux release 7.9.2009 (Core)

ElasticSearch Version：7.9.2, JVM: 15

1.报错详情

$ curl 10.10.13.1:9200

{
    "error": {
        "root_cause": [{
            "type": "master_not_discovered_exception",
            "reason": null
        }],
        "type": "master_not_discovered_exception",
        "reason": null
    },
    "status": 503
}

这是因为你安装的 单节点 或 集群 没有初始节点导致，指定一个即可

2.解决报错

$ vim /data/elasticsearch/config/elasticsearch.yml

cluster.initial_master_nodes: node-1
#增加这一行，我这里 node-1 是默认的节点名称，修改为自己的节点名称即可

3.验证

$ curl 10.10.13.1:9200

  "name" : "node-1",
  "cluster_name" : "linlikesi",
