Head插件安装

1. Head插件简介
ElasticSearch-head是一个H5编写的ElasticSearch集群操作和管理工具,可以对集群进行傻瓜式操作。

  • 显示集群的拓扑,并且能够执行索引和节点级别操作
  • 搜索接口能够查询集群中原始json或表格格式的检索数据
  • 能够快速访问并显示集群的状态
  • 有一个输入窗口,允许任意调用RESTful API。这个接口包含几个选项,可以组合在一起以产生有趣的结果;
  • 5.0版本之前可以通过plugin名安装,5.0之后可以独立运行。

2. Head插件安装
(1)安装NodeJS

[root@cyj ~]# yum install -y nodejs

(2)安装npm

[root@cyj~]#  npm install -g cnpm --registry=https://registry.npm.taobao.org

(3)使用npm安装grunt

[root@cyj~]# npm install -g grunt
npm WARN deprecated coffee-script@1.10.0: CoffeeScript on NPM has moved to "coffeescript" (no hyphen)
npm WARN gentlyRm not removing /usr/bin/grunt as it wasn't installed by /usr/lib/node_modules/grunt

[root@cyj ~]# 
[root@cyj ~]# npm install -g grunt-cli --registry=https://registry.npm.taobao.org --no-proxy

  ├─┬ nopt@3.0.6 
  │ └── abbrev@1.1.1

[root@cyj ~]#  

(4)版本确认

[es@cyj ~]$ node -v
v6.12.0
[es@cyj ~]$ npm -v
3.10.10
[es@cyj ~]$ grunt -version
grunt-cli v1.2.0
[es@cyj ~]$

(5)下载head插件源码

[es@cyj ~]$ git clone git://github.com/mobz/elasticsearch-head.git
[es@cyj ~]$ cd elasticsearch-head
[es@cyj ~]$ npm install
[es@cyj ~]$ npm run start

3. 配置elasticsearch
(1)配置 ElasticSearch,使得HTTP对外提供服务

[es@cyj elasticsearch-6.4.2]$ vi config/elasticsearch.yml

添加如下内容

# 增加新的参数,这样head插件可以访问es。设置参数的时候:后面要有空格
http.cors.enabled: true
http.cors.allow-origin: "*"

Kibana插件

(1) 下载kibana插件
https://www.elastic.co/downloads/kibana

注意,ElasticSearch版本是6.4.2,kibana的版本必须对应,所以,此处下载kibana-6.4.2-linux-x86_64.tar.gz

[es@cyj ~]$ wget https://artifacts.elastic.co/downloads/kibana/kibana-6.4.2-linux-x86_64.tar.gz

[es@node1 ~]$ 

(2) 解压

[es@cyj ~]$ tar -zxvf kibana-6.4.2-linux-x86_64.tar.gz
[es@node1 ~]$ cd kibana-6.4.2-linux-x86_64
[es@node1 kibana-6.4.2-linux-x86_64]$

(3) 修改配置
修改kibana配置文件kibana.yml
需要修改的主要有三处

#设置kibana监听的端口
server.port: 5601
#设置kibana的地址
server.host: xxxx.xxxx.xxxx.xxxx
#设置elastcisearch的地址端口
elasticsearch.url: "http://xxxx.xxxx.xxxx.xxxx:9200"

(4) 启动kibana

[root@cyj kibana-6.4.2-linux-x86_64]# ./bin/kibana

(5) 浏览器访问http://xxxx.xxxx.xxxx.xxxx:5601

GET _analyze?pretty
{
  "analyzer": "ik_smart",
  "text":"安徽省长江流域"
}

分词结果:

{
  "tokens": [
    {
      "token": "安徽省",
      "start_offset": 0,
      "end_offset": 3,
      "type": "CN_WORD",
      "position": 0
    },
    {
      "token": "长江流域",
      "start_offset": 3,
      "end_offset": 7,
      "type": "CN_WORD",
      "position": 1
    }
  ]
}
  • ik_max_word
GET _analyze?pretty
{
  "analyzer": "ik_max_word",
  "text": "安徽省长江流域"
}

分词结果:

{
  "tokens": [
    {
      "token": "安徽省",
      "start_offset": 0,
      "end_offset": 3,
