添加节点使本地集群 Elasticsearch [7.8]

Question

我正在学习 Elastic Search (v7.8)，所以我做了一个本地集群来测试它。我制作了 3 个 Ubuntu 18 的虚拟机，相同数量的资源，在具有 IP 的同一网络中：

192.168.1.77
192.168.1.76
192.168.1.75

所有正确的个人安装，每个都回复她API：

curl -XGET localhost:9200/?pretty

但是当我尝试编辑集群时 /etc/elasticsearch/elasticsearch.yml 每个节点都形成了自己的同名集群。这是我的文件：https://gist.github.com/RedxLus/f8eb561157c7f2b61fb4dfaa74fe8868

这是每个节点的输出。一模一样:

curl -XGET 192.168.1.77:9200/_cluster/health?pretty

{
  "cluster_name" : "luisiblog",
  "status" : "green",
  "timed_out" : false,
  "number_of_nodes" : 1,
  "number_of_data_nodes" : 1,
  "active_primary_shards" : 0,
  "active_shards" : 0,
  "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
}

我不知道这是配置错误还是我跳过了任何添加节点的步骤。我希望他们能帮助我。非常感谢大家。

首先是您缺少 network.host 正确的值，该值应该是 0.0.0.0 以确保它在非环回地址上可见。

你能试试下面的配置吗:

#这是针对节点 1

 cluster.name: elasticsearch
    node.name: node-1
    network.host: 0.0.0.0
    discovery.seed_hosts: ["192.168.1.77","192.168.1.76","192.168.1.75"]
    cluster.initial_master_nodes: ["192.168.1.77"]
    discovery.zen.minimum_master_nodes : 1
    node.master: true

#这是针对节点 2

cluster.name: elasticsearch
node.name: node-2
network.host: 0.0.0.0
discovery.seed_hosts: ["192.168.1.77","192.168.1.76","192.168.1.75"]
cluster.initial_master_nodes: ["192.168.1.77"]
discovery.zen.minimum_master_nodes : 1
node.master: false

# 这是节点 3

cluster.name: elasticsearch
node.name: node-3
network.host: 0.0.0.0
discovery.seed_hosts: ["192.168.1.77","192.168.1.76","192.168.1.75"]
cluster.initial_master_nodes: ["192.168.1.77"]
discovery.zen.minimum_master_nodes : 1
node.master: false

请注意，我正在创建一个专用主节点，在本例中为 node-1
