本文详细介绍了如何在两台机器上配置Elasticsearch集群，包括master和slave节点的设置，以及为解决大量数据插入时的gcoverhead问题而进行的ping超时时间调整。同时，还提供了Kibana和Elasticsearch-head的配置指南。

设置elasticsearch

两台机器：

master ip 192.168.31.106

slave ip 192.168.31.162

master elasticsearch.yml

bootstrap.memory_lock: false
bootstrap.system_call_filter: false

node.name: node-1
node.master: true
node.data: true
network.bind_host: 192.168.31.106
network.publish_host: 192.168.1.106
network.host: 0.0.0.0
http.max_content_length: 1024mb
discovery.zen.ping.unicast.hosts: ["192.168.31.162"]
http.cors.enabled: true
http.cors.allow-origin: "*"
discovery.zen.ping_timeout: 10s
discovery.zen.minimum_master_nodes: 2
discovery.zen.fd.ping_timeout: 10000s
discovery.zen.fd.ping_retries: 10

The discovery.zen.ping_timeout (which defaults to 3s) determines how long the node will wait before deciding on starting an election or joining an existing cluster.

discovery.zen.fd：

ping_timeout

How long to wait for a ping response, defaults to 30s.

ES在大量插入数据时会产生gc overhead 错误，在gc overhead 过程中会进入stop-the-world状态，导致ping不通，因此调整ping的时间长度

slave elasticsearch.yml

bootstrap.memory_lock: false
bootstrap.system_call_filter: false

node.name: node-2
node.master: true
node.data: true
network.bind_host: 192.168.31.162
network.publish_host: 192.168.1.162
network.host: 0.0.0.0
http.max_content_length: 1024mb
discovery.zen.ping.unicast.hosts: ["192.168.31.106"]
http.cors.enabled: true
http.cors.allow-origin: "*"
discovery.zen.ping_timeout: 10s
discovery.zen.minimum_master_nodes: 2
discovery.zen.fd.ping_timeout: 10000s
discovery.zen.fd.ping_retries: 10

设置node.master: true ，两台机器哪个先启动，哪个就是master。

设置kibana

server.host: "0.0.0.0"
elasticsearch.url: "http://192.168.1.162:9200"

设置ElasticSearh-head

下载elasticsearch-head

cd /path/to/elasticsearch-head
npm install -g grunt-cli
npm install
grunt server
http://localhost:9100/
