单节点集群未发现elastic search master elastic search v7.11.1

Question

我正在尝试在单个虚拟机中设置三个节点的弹性搜索。但是主节点根本没有发现。如果我将cluster.initial_master_nodes作为一个节点开始。选择了Master，但没有发生群集形成，并且发生了RemoteTransportException。我尝试了太多的可能性，但是没有成功。

这是我的配置。

我在windows上尝试了同样的配置，运行良好。但是linux cent os我正面临着这个问题。

Os Version: CentOS Linux release 7.9.2009 (Core)
Elastic : 7.11.2 RPM Distribution
Node1

cluster.name: escluster
node.name: master-1
path.data: /var/lib/elasticsearch
path.logs: /var/log/elasticsearch
network.host: 0.0.0.0
http.port: 9200
discovery.seed_hosts: ["127.0.0.1"]
cluster.initial_master_nodes: ["master-1", "master-2","master-3"]
node.max_local_storage_nodes: 3

Node2

cluster.name: escluster
node.name: master-2
path.data: /var/lib/elasticsearch
path.logs: /var/log/elasticsearch
network.host: 0.0.0.0
http.port: 9201
discovery.seed_hosts: ["127.0.0.1"]
cluster.initial_master_nodes: ["master-1", "master-2","master-3"]
node.max_local_storage_nodes: 3

Node3
cluster.name: escluster
node.name: master-3
path.data: /var/lib/elasticsearch
path.logs: /var/log/elasticsearch
network.host: 0.0.0.0
http.port: 9202
discovery.seed_hosts: ["127.0.0.1"]
cluster.initial_master_nodes: ["master-1", "master-2","master-3"]
node.max_local_storage_nodes: 3

所有三个节点都成功启动。但是星团的形成并没有发生。

任何帮助都将不胜感激！

Answer 1

按如下方式更改YML：

node1:
http.port: 9200
transport.port:9300
discovery.seed_hosts: ["127.0.0.1"]
cluster.initial_master_nodes: ["master-1"]
node2:
http.port: 9201
transport.port:9301
discovery.seed_hosts: ["127.0.0.1:9300"]
cluster.initial_master_nodes: ["master-1:9300"]
node3:
http.port: 9202
transport.port:9302
discovery.seed_hosts: ["127.0.0.1:9300"]
cluster.initial_master_nodes: ["master-1:9300"]

Answer 2

在启动集群之前，我们需要确保节点已创建。创建节点后，群集将按预期形成。
