elasticsearch 如何在elasticsearch中配置一个集群中的两个节点？

我在远程服务器1（node1）和远程服务器2（node2）中安装了两个Elasticsearch安装实例，我希望将这两个节点连接到一个集群中，但是我也在一个服务器中安装了kibana，当我运行GET_cluster/health时，我得到

{
"cluster_name" : "elasticsearch",
"status" : "green",
"timed_out" : false,
"number_of_nodes" : 1,
"number_of_data_nodes" : 1,
"active_primary_shards" : 1,
"active_shards" : 1,
"relocating_shards" : 0,
"initializing_shards" : 0,
"unassigned_shards" : 0,
"delayed_unassigned_shards" : 0,
"number_of_pending_tasks" : 0,
"number_of_in_flight_fetch" : 0,
"task_max_waiting_in_queue_millis" : 0,
"active_shards_percent_as_number" : 100.0
}

在为node1和node2的两种配置提供示例时，您是否可以提供帮助，以及如何确认两个节点都添加到一个集群中

下面是服务器1中的elasticsearch.yml文件

bootstrap.memory_lock: false
cluster.name: elasticsearch
http.port: 9200
node.data: true
node.ingest: true
node.master: true
node.max_local_storage_nodes: 2
node.name: Server1
path.data: C:\ProgramData\Elastic\Elasticsearch\data
path.logs: C:\ProgramData\Elastic\Elasticsearch\logs
transport.tcp.port: 9300
xpack.license.self_generated.type: basic
xpack.security.enabled: false
discovery.zen.minimum_master_nodes: 2
discovery.zen.ping.unicast.hosts: ["Server1","Server2"]
network.host: Server1

Server2:elasticsearch.yml文件-

bootstrap.memory_lock: false
cluster.name: elasticsearch
http.port: 9200
node.data: true
node.ingest: true
node.master: false
node.max_local_storage_nodes: 1
node.name: Server2
path.data: C:\ProgramData\Elastic\Elasticsearch\data
path.logs: C:\ProgramData\Elastic\Elasticsearch\logs
transport.tcp.port: 9300
xpack.license.self_generated.type: basic
xpack.security.enabled: false
discovery.zen.ping.unicast.hosts: ["Server1","Server2"]
network.host: Server2

谢谢

您将最小主节点（discovery.zen.minimum主节点）配置为2，但第二个节点具有

node.master：false

---

将第二个节点更改为master:true或将最小主节点数减少为1

有最小主节点数的公式

(total number of master-eligible nodes / 2 + 1)

因此，一个集群中的两个节点是一个主节点，一个是从节点

As of formula (2 / 2+1) = 0.6666 ~ 1

discovery.zen.minimum_master_nodes: 1

---

为了帮助其他人，让我将这两个节点的配置

主节点配置：

bootstrap.memory_lock: false
cluster.name: elasticsearch
http.port: 9200
node.data: true
node.ingest: true
node.master: true
node.max_local_storage_nodes: 2
node.name: Server1
path.data: C:\ProgramData\Elastic\Elasticsearch\data
path.logs: C:\ProgramData\Elastic\Elasticsearch\logs
transport.tcp.port: 9300
xpack.license.self_generated.type: basic
xpack.security.enabled: false
discovery.zen.minimum_master_nodes: 1
discovery.zen.ping.unicast.hosts: ["Server1","Server2"]
network.host: Server1

bootstrap.memory_lock: false
cluster.name: elasticsearch
http.port: 9200
node.data: true
node.ingest: true
node.master: false
node.max_local_storage_nodes: 1
node.name: Server2
path.data: C:\ProgramData\Elastic\Elasticsearch\data
path.logs: C:\ProgramData\Elastic\Elasticsearch\logs
transport.tcp.port: 9300
xpack.license.self_generated.type: basic
xpack.security.enabled: false
discovery.zen.minimum_master_nodes: 1
discovery.zen.ping.unicast.hosts: ["Server1","Server2"]
network.host: Server2

从节点配置：

bootstrap.memory_lock: false
cluster.name: elasticsearch
http.port: 9200
node.data: true
node.ingest: true
node.master: true
node.max_local_storage_nodes: 2
node.name: Server1
path.data: C:\ProgramData\Elastic\Elasticsearch\data
path.logs: C:\ProgramData\Elastic\Elasticsearch\logs
transport.tcp.port: 9300
xpack.license.self_generated.type: basic
xpack.security.enabled: false
discovery.zen.minimum_master_nodes: 1
discovery.zen.ping.unicast.hosts: ["Server1","Server2"]
network.host: Server1

bootstrap.memory_lock: false
cluster.name: elasticsearch
http.port: 9200
node.data: true
node.ingest: true
node.master: false
node.max_local_storage_nodes: 1
node.name: Server2
path.data: C:\ProgramData\Elastic\Elasticsearch\data
path.logs: C:\ProgramData\Elastic\Elasticsearch\logs
transport.tcp.port: 9300
xpack.license.self_generated.type: basic
xpack.security.enabled: false
discovery.zen.minimum_master_nodes: 1
discovery.zen.ping.unicast.hosts: ["Server1","Server2"]
network.host: Server2

完成此操作后，您将得到如下响应：

{
  "cluster_name": "elasticsearch",
  "status": "green",
  "timed_out": false,
  "number_of_nodes": 2,
  "number_of_data_nodes": 2,
  "active_primary_shards": 1,
  "active_shards": 2,
  "relocating_shards": 0,
  "initializing_shards": 0,
  "unassigned_shards": 0,
  "delayed_unassigned_shards": 0,
  "number_of_pending_tasks": 0,
  "number_of_in_flight_fetch": 0,
  "task_max_waiting_in_queue_millis": 0,
  "active_shards_percent_as_number": 100.0
}

谢谢

感谢您的帮助，我还需要将该行同时放入两个配置中，然后它就工作了：discovery.zen.minimum_master_nodes:1这是错误的信息。2/2+1是2。如果你能提供日志，回答这个问题会很有帮助
