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。

    4.配置

    4.1停止ElasticSearch

    如果ElasticSearch已经启动，需要先停止
    1. [es@node1 ~]$ jps
    2. 3261 Elasticsearch
    3. 3375 Jps
    4. [es@node1 ~]$ kill 3261

    4.2配置 ElasticSearch，使得HTTP对外提供服务

    1. [es@node1 elasticsearch-6.1.1]$ vi config/elasticsearch.yml
    添加如下内容
    1. # 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
    2. http.cors.enabled: true
    3. http.cors.allow-origin: "*"

    4.3 修改Head插件配置文件

    1. [es@node1 elasticsearch-head-master]$ vi Gruntfile.js
    找到connect：server，添加hostname一项，如下
    1. connect: {
    2. server: {
    3.   options: {
    4.     hostname: '0.0.0.0',
    5.     port: 9100,
    6.     base: '.',
    7.     keepalive: true
    8.   }
    9. }
    10. }

    5.启动

    5.1启动elasticsearch

    首先确认elasticsearch已经启动
    1. [es@node1 elasticsearch-6.1.1]$ bin/elasticsearch -d
    2. [es@node1 elasticsearch-6.1.1]$ jps
    3. 3451 Jps
    4. 3436 Elasticsearch
    5. [es@node1 elasticsearch-6.1.1]$

    5.2启动head

    通过命令grunt server启动head
    1. [es@node1 elasticsearch-head-master]$ grunt server
    2. Running "connect:server" (connect) task
    3. Waiting forever...
    4. Started connect web server on http://node1:9100
    或者通过命令npm run start也可以启动head
    1. [es@node1 elasticsearch-head-master]$ npm run start
    2. > elasticsearch-head@0.0.0 start /home/es/elasticsearch-head-master
    3. > grunt server
    4. Running "connect:server" (connect) task
    5. Waiting forever...
    6. Started connect web server on http://node1:9100

    5.3访问9100端口

    http://node1:9100/

    6 简单应用

    6.1创建索引

    1. [root@node1 ~]# curl -XPUT node1:9200/test
    2. {"acknowledged":true,"shards_acknowledged":true,"index":"test"}[root@node1 ~]#
