1.下载解压es和jdk包

[root@node1 ~]# wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.7.1.tar.gz

[root@node1 ~]# tar xvf elasticsearch-6.7.1.tar.gz -C /opt/

[root@node1 ~]# wget https://download.oracle.com/otn-pub/java/jdk/8u202-b08/1961070e4c9b4e26a04e7f5a083f551e/jdk-8u202-linux-x64.rpm?AuthParam=1552723272_02cde009ff2384cfcf01e2c377d085cc

[root@node1 ~]# scp jdk-8u202-linux-x64.rpm  node2:/root/    --将jdk传到各节点上

[root@node1 ~]# scp jdk-8u202-linux-x64.rpm  node3:/root/    --将jdk传到各节点上

[root@node1 ~]# rpm -ivh jdk-8u202-linux-x64.rpm             --在各节点安装jdk

[root@node1 ~]# cd /opt/elasticsearch-6.7.1/

[root@node1 elasticsearch-6.7.1]# useradd wuhan     --创建es用户,es不能用root用户启动

[root@node1 elasticsearch-6.7.1]# passwd wuhan

更改用户 wuhan 的密码 。

新的 密码：

无效的密码： 密码少于 8 个字符

重新输入新的 密码：

passwd：所有的身份验证令牌已经成功更新。

[root@node1 elasticsearch-6.7.1]# chown -R wuhan:wuhan /opt/elasticsearch-6.7.1/

[root@node1 elasticsearch-6.7.1]# vim /etc/security/limits.conf 

*      soft    nofile    65535

*      hard    nofile    65535

[root@node1 elasticsearch-6.7.1]# vim /etc/sysctl.conf 

vm.max_map_count=262144

[root@node1 elasticsearch-6.7.1]# sysctl -p

[root@node1 elasticsearch-6.7.1]# vim /opt/elasticsearch-6.7.1/config/elasticsearch.yml

cluster.name: wuhan     --设置集群节点名

node.name: node-1       --为每台机器设置node名字,各节点名字不能一样

path.data: /opt/elasticsearch-6.7.1/data    --es数据目录

path.logs: /opt/elasticsearch-6.7.1/logs    --日志目录

discovery.zen.ping.unicast.hosts: ["node1", "node2", "node3", "node4"]

network.host: 172.16.8.23    --绑定本机的IP地址

http.port: 9200              --指定端口

[root@node1 elasticsearch-6.7.1]#

2.将node1的es文件复制到其它节点(与node1配置一样)

[root@node1 opt]# scp -r elasticsearch-6.7.1 node2:/opt/

[root@node1 opt]# scp -r elasticsearch-6.7.1 node3:/opt/

[root@node2 ~]# chown -R wuhan:wuhan /opt/elasticsearch-6.7.1/

[root@node2 ~]# vim /etc/security/limits.conf 

*      soft    nofile    65535

*      hard    nofile    65535

[root@node2 ~]# vim /etc/sysctl.conf

vm.max_map_count=262144

[root@node2 ~]# sysctl -p

3.启动各节点的es服务

[root@node1 ~]# su - wuhan 

[wuhan@node1 ~]$ cd /opt/elasticsearch-6.7.1/bin/

[wuhan@node1 bin]$ ./elasticsearch -d

[wuhan@node1 bin]# curl http://172.16.8.23:9200

{

  "name" : "node-1",

  "cluster_name" : "wuhan",

  "cluster_uuid" : "_na_",

  "version" : {

    "number" : "6.7.1",

    "build_flavor" : "default",

    "build_type" : "tar",

    "build_hash" : "2f32220",

    "build_date" : "2019-04-02T15:59:27.961366Z",

    "build_snapshot" : false,

    "lucene_version" : "7.7.0",

    "minimum_wire_compatibility_version" : "5.6.0",

    "minimum_index_compatibility_version" : "5.0.0"

  },

  "tagline" : "You Know, for Search"

}

[wuhan@node1 bin]# 

4.安装head插件

[root@node1 ~]$ wget https://nodejs.org/dist/v11.13.0/node-v11.13.0-linux-x64.tar.xz

[root@node1 ~]$ tar xvf node-v11.13.0-linux-x64.tar.xz 

[root@node1 ~]$ mv node-v11.13.0-linux-x64 /opt/node-v11.13.0

[root@node1 ~]$ vim /etc/profile

export PATH=$PATH:/opt/node-v11.13.0/bin

[root@node1 ~]$ git clone git://github.com/mobz/elasticsearch-head.git

[root@node1 ~]# cd elasticsearch-head/

[root@node1 elasticsearch-head]# npm  install

5.修改es配置文件,重启服务

[wuhan@node1 bin]# vim /opt/elasticsearch-6.7.1/config/elasticsearch.yml 

http.cors.enabled: true 

http.cors.allow-origin: "*"

[wuhan@node1 bin]$ jps

[wuhan@node1 bin]$ kill -9 17849

[wuhan@node1 bin]$ cd /opt/elasticsearch-6.7.1/bin

[wuhan@node1 bin]$ ./elasticsearch -d

6.访问web页面

[root@node1 elasticsearch-head]# grunt server &

[1] 20212

[root@node1 elasticsearch-head]# 

错误提示:
