2.1 Head插件簡介

ElasticSearch-head是一個H5編寫的ElasticSearch集群操作和管理工具,，可以對集群進行傻瓜式操作,。

顯示集群的拓撲,并且能夠執(zhí)行索引和節(jié)點級別操作
搜索接口能夠查詢集群中原始json或表格格式的檢索數(shù)據(jù)
能夠快速訪問并顯示集群的狀態(tài)
有一個輸入窗口,允許任意調(diào)用RESTful API,。這個接口包含幾個選項,可以組合在一起以產(chǎn)生有趣的結(jié)果;
5.0版本之前可以通過plugin名安裝,，5.0之后可以獨立運行,。

2.3 配置

（0）停止ElasticSearch
如果ElasticSearch已經(jīng)啟動，需要先停止

[es@node1 ~]$ jps
3261 Elasticsearch
3375 Jps
[es@node1 ~]$ kill 32611

（1）配置 ElasticSearch,，使得HTTP對外提供服務(wù)

[es@node1 elasticsearch-6.1.1]$ vi config/elasticsearch.yml1

添加如下內(nèi)容

# 增加新的參數(shù),，這樣head插件可以訪問es。設(shè)置參數(shù)的時候:后面要有空格
http.cors.enabled: true
http.cors.allow-origin: "*"1

（2）修改Head插件配置文件

[es@node1 elasticsearch-head-master]$ vi Gruntfile.js1

找到connect：server，添加hostname一項,，如下

connect: {
                        server: {
                                options: {
                                        hostname: 'node1',
                                        port: 9100,
                                        base: '.',
                                        keepalive: true
                                }
                        }
                }

首先確認elasticsearch已經(jīng)啟動

[es@node1 elasticsearch-6.1.1]$ bin/elasticsearch -d
[es@node1 elasticsearch-6.1.1]$ jps
3451 Jps
3436 Elasticsearch
[es@node1 elasticsearch-6.1.1]$1

（2）啟動head
通過命令grunt server啟動head

[es@node1 elasticsearch-head-master]$ grunt server
Running "connect:server" (connect) task

或者通過命令npm run start也可以啟動head

[es@node1 elasticsearch-head-master]$ npm run start

> [email protected] start /home/es/elasticsearch-head-master
> grunt server

Running "connect:server" (connect) task

（3）訪問9100端口
http://node1:9100/

如果出現(xiàn)“未連接”,，請修改localhost為node1，然后單擊“連接”按鈕

2.5 簡單應(yīng)用

（1）創(chuàng)建索引

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

（2）查看head變化
