2.1 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。

2.2 Head插件安装

（1）安装NodeJS

[root@node1 ~]# yum install -y nodejs

或者自己下载tar文件解压

wget https://npm.taobao.org/mirrors/node/latest-v4.x/node-v4.5.0-linux-x64.tar.gz

tar -zxvf node-v4.5.0-linux-x64.tar.gz

配置下环境变量,编辑/etc/profile添加

export NODE_HOME=/usr/local/node-v4.5.0-linux-x64

export PATH=NODE_HOME/bin/

export NODE_PATH=$NODE_HOME/lib/node_modules

执行 source /etc/profile

2.3 配置

（0）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

（1）配置 ElasticSearch，使得HTTP对外提供服务

[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: "*"

（2）修改Head插件配置文件

[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. }

2.4 启动

（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]$

（2）启动head

通过命令grunt server启动head

[es@node1 elasticsearch-head-master]$ grunt server

1. 需要在head的目录下运行
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. [email protected] 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

（3）访问9100端口

http://10.105.45.32:9100/

如果出现“未连接”，请修改localhost为node1，然后单击“连接”按钮

2.5 简单应用

（1）创建索引

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

（2）查看head变化
