Pass an initial list of hosts to perform discovery when this node is started:
The default list of hosts is [“127.0.0.1”, “[::1]”]

Bootstrap the cluster using an initial set of master-eligible nodes:
#es7.x 之后新增的配置，初始化一个新的集群时需要此配置来选举master
cluster.initial_master_nodes: [“node-1”, “node-2”,“node-3”]

节点node-2配置
======================== Elasticsearch Configuration =========================
NOTE: Elasticsearch comes with reasonable defaults for most settings.
Before you set out to tweak and tune the configuration, make sure you
understand what are you trying to accomplish and the consequences.
The primary way of configuring a node is via this file. This template lists
the most important settings you may want to configure for a production cluster.
Please consult the documentation for further information on configuration options:
https://www.elastic.co/guide/en/elasticsearch/reference/index.html
---------------------------------- Cluster -----------------------------------
Use a descriptive name for your cluster:
#配置es的集群名称，同一个集群中的多个节点使用相同的标识
#如果在同一网段下有多个集群，就可以用这个属性来区分不同的集群。
cluster.name: my-cluster
------------------------------------ Node ------------------------------------
Use a descriptive name for the node:
#节点名称
node.name: node-2
#是不是有资格竞选主节点
node.master: true
Add custom attributes to the node:
#node.attr.rack: r1
----------------------------------- Paths ------------------------------------
Path to directory where to store the data (separate multiple locations by comma):
#数据存储路径
path.data: /opt/es/data
Path to log files:
#日志存储路径
path.logs: /opt/es/logs
----------------------------------- Memory -----------------------------------
Lock the memory on startup:
#ES默认开启了内存地址锁定，为了避免内存交换提高性能。但是Centos6不支持SecComp功能，启动会报错，所以需要将其设置为false
#bootstrap.memory_lock: true
Make sure that the heap size is set to about half the memory available
on the system and that the owner of the process is allowed to use this
limit.
Elasticsearch performs poorly when the system is swapping the memory.
---------------------------------- Network -----------------------------------
By default Elasticsearch is only accessible on localhost. Set a different
address here to expose this node on the network:
#节点所绑定的IP地址，并且该节点会被通知到集群中的其他节点
#通过指定相同网段的其他节点会加入该集群中 0.0.0.0任意IP都可以访问elasticsearch
network.host: 10.10.164.2
bootstrap.system_call_filter: false
By default Elasticsearch listens for HTTP traffic on the first free port it
finds starting at 9200. Set a specific HTTP port here:
#作为数据节点
node.data: true
#对外提供服务的http端口，默认为9200
http.port: 9200
是否支持跨域
http.cors.enabled: true
*表示支持所有域名
http.cors.allow-origin: “*”
#内部节点之间沟通端口
transport.tcp.port: 9300
#设置是否压缩TCP传输时的数据，默认为false
transport.tcp.compress: true
#network.publish_host:10.10.164.2
cluster.routing.allocation.disk.threshold_enabled: false
