This document is aimed at the deployment of es on 3 nodes in centos7 environment. The 3-node ip is 172.16.10.102.172.16.10.103172.16.10.104 respectively.

First, add host

Add host configuration under each node

172.16.10.102 HadoopMaster

172.16.10.103 HadoopSlave1

172.16.10.104 HadoopSlave2

Second, then download the es installation package

Cd / opt wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.4.0.tar.gz

Third, extract the es installation package

Tar-zxvf elasticsearch-6.4.0.tar.gz

4. Edit the es configuration file (the master configuration is as follows, and the other two slave can modify the node.master:false)

Vim config/elasticsearch.yml

Network.host: 0.0.0.0

Discovery.zen.ping_timeout: 120s

Client.transport.ping_timeout: 60s

Discovery.zen.ping.unicast.hosts: ["172.16.10.102", "172.16.10.103", "172.16.10.104"]

Cluster.name: escluster

Node.name: HadoopMaster

Path.data: / opt/elasticsearch-6.4.0/data

Path.logs: / opt/elasticsearch-6.4.0/datalog

Node.master: true

Node.data: true

Node.attr.rack: r1

Bootstrap.memory_lock: true

Bootstrap.system_call_filter: false

Http.port: 9200

Http.cors.enabled: true

Http.cors.allow-origin: "*"

Fifth, modify the system parameters

Vim / etc/security/limits.conf

Add

Soft nofile 65536hard nofile 65536soft nproc 65536hard nproc 65536soft memlock unlimitedhard memlock unlimited

Vim / etc/sysctl.conf

Add

Vm.max_map_count=655360

Then reload the system parameters

Sysctl-p

6. Start with es user

Groupadd es

Useradd es- g es-p elasticsearch-6.4.0

Chown-R es:es elasticsearch-6.4.0

Su es

. / elasticsearch-d

7. Install head

Git clone git://github.com/mobz/elasticsearch-head.git under a random folder

Install the nodejs environment

Yum-y install nodejs

Cd elasticsearch-head/

Npm install

Npm install-g grunt-cli

Grunt server &

Open http://localhost:9100

(if prompted to report an error phantomjs-prebuilt@2.1.16 install: node install.js)

Npm install phantomjs-prebuilt@2.1.16-ignore-scripts is fine.

Restart the es program.

Open the web page: http://172.16.10.102:9100 (if 9200 of the head cannot be connected, check the http.cors.enabled: true of the configuration file

Http.cors.allow-origin: whether "*" is configured)
