将elasticsearch节点添加到多台计算机

Question

我目前正在研究将多台机器中的节点添加到集群中。主节点应该是x. x. x.246，我要添加的数据节点是x. x. x.99。运行最新的elasticsearch 7.6。我已经确定这两个弹性是相同的版本。

cluster.name : elasticsearch
node.name : Node_master
node.master : true
node.data : false
network.host : x.x.x.246
http.port : 9200
transport.tcp.port: 9300
discovery.seed_hosts:
   - x.x.x.246:9300
   - x.x.x.99:9301
cluster.initial_master_nodes:
   - x.x.x.246:9300
   - x.x.x.99:9301

cluster.name : elasticsearch
node.name : Node-1
node.master : false
node.data : true
network.host : x.x.x.99
http.port : 9201
transport.tcp.port: 9301
discovery.seed_hosts:
   - x.x.x.246:9300
   - x.x.x.99:9301
cluster.initial_master_nodes:
   - x.x.x.246:9300
   - x.x.x.99:9301

代码有什么问题？我想我遵循了这个指示

discovery.seed_hosts:
   - x.x.x.246:9300
cluster.initial_master_nodes:
   - Node_master

Answer 1

discovery.seed_hosts：这应该包含符合条件的主节点列表，其形式为host或host： port。

集群。初始_master_节点：这应该是符合主节点资格的节点列表，将用于第一次形成集群。列表包含节点名称。

在您的情况下，您只有一个符合条件的主节点，因此请按如下所示更改上述属性。

主节点更改为：

discovery.seed_hosts:
   - x.x.x.246:9300
cluster.initial_master_nodes:
   - Node_master

对于数据节点cluster.initial_master_nodes并将种子主机更改为：

discovery.seed_hosts:
       - x.x.x.246:9300
