elasticsearch-6.7.1叢集搭建

elasticsearch下載地址:ttps://github.com/elastic/elasticsearch/releases

ik下載地址:

1.下載解壓es和jdk包

[root@node1 ~]# wget

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

[root@node1 ~]# wget

[root@node1 ~]# scp jdk-8u202-linux-x64.rpm  node2:/root/    --將jdk傳到各節點上

[root@node1 ~]# scp jdk-8u202-linux-x64.rpm  node3:/root/    --將jdk傳到各節點上

[root@node1 ~]# rpm -ivh jdk-8u202-linux-x64.rpm             --在各節點安裝jdk

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

[root@node1 elasticsearch-6.7.1]# useradd wuhan     --建立es使用者,es不能用root使用者啟動

[root@node1 elasticsearch-6.7.1]# passwd wuhan

更改使用者 wuhan 的密碼 。

新的 密碼：

無效的密碼： 密碼少於 8 個字元

重新輸入新的 密碼：

passwd：所有的身份驗證令牌已經成功更新。

[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     --設定叢集節點名

node.name: node-1       --為每臺機器設定node名字,各節點名字不能一樣

path.data: /opt/elasticsearch-6.7.1/data    --es資料目錄

path.logs: /opt/elasticsearch-6.7.1/logs    --日誌目錄

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

network.host: 172.16.8.23    --繫結本機的IP地址

http.port: 9200              --指定埠

[root@node1 elasticsearch-6.7.1]#

2.將node1的es檔案複製到其它節點(與node1配置一樣)

[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.啟動各節點的es服務

[root@node1 ~]# su - wuhan 

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

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

[wuhan@node1 bin]# curl

{

  "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.安裝head外掛

[root@node1 ~]$ wget

[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

[root@node1 elasticsearch-head]# npm run start

> elasticsearch-head@0.0.0 start /root/elasticsearch-head

5.修改es配置檔案,重啟服務

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

http.cors.enabled: true 

http.cors.allow-origin: "*"

[wuhan@node1 bin]$ jps

17849 Elasticsearch

17935 Jps

[wuhan@node1 bin]$ kill -9 17849

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

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

6.訪問web頁面

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

[1] 20212

[root@node1 elasticsearch-head]# 

錯誤提示:

npm ERR! code ELIFECYCLE

npm ERR! errno 1

解決方法:

ES和ik版本必須一至,否則會出錯
