master_not_discovered_exception ElasticSearch 单节点

Question

我正在尝试在单个主机上设置 elasticsearch。这是我的配置的样子：

弹性搜索.yml

node.name: ${HOSTNAME}

network.host: _site_, _local_
http.port: 9200
transport.tcp.port: 9300
cluster.name: "test_cluster"
node.local: true

kibana.yml

server.host: 0.0.0.0
elasticsearch.url: http://localhost:9200

在以下命令中：

curl -XGET 'localhost:9200/_cluster/health?pretty'

我收到以下消息：

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

在日志文件中，我看到以下消息：

not enough master nodes discovered during pinging (found [[]], but needed [-1]), pinging again

有人可以在这里指出我正确的方向吗？

Answer 1

我花了几天（叹气）基本上这个。我试图将我的单节点集群从 6.x 升级到 7.x，我一直在“master_not_discovered_exception”的山上死去。

最终为我解决的是检查全新安装的 7.x。

对于我的单节点集群，我的/etc/elasticsearch/elasticsearch.yml需要以下行：

discovery.type: single-node

我希望这能让其他人免于像我一样度过几天。在我的辩护中，我对 es 很陌生。

First I dont think you need network.host setting for this.

In your log it is trying to get a master, but result is 0

Can you try setting properties like:

node.master: true
node.data:true

Also can you please put more logs here, if it doesnt work
