ES系列二、CentOS7安装ES head6.3.1
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。

[es@node1 elasticsearch-head-master]$ 4.配置
4.1停止ElasticSearch
如果ElasticSearch已经启动，需要先停止
[es@node1 ~]$ jps
3261 Elasticsearch
3375 Jps
[es@node1 ~]$ kill 32614.2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
# 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: "*"4.3 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
connect: {
server: {
options: {
hostname: '0.0.0.0',
port: 9100,
base: '.',
keepalive: true
}
}
}5.启动
5.1启动elasticsearch
首先确认elasticsearch已经启动
[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]$5.2启动head
通过命令grunt server启动head
[es@node1 elasticsearch-head-master]$ grunt server
Running "connect:server" (connect) task
Waiting forever...
Started connect web server on http://node1:9100或者通过命令npm run start也可以启动head
[es@node1 elasticsearch-head-master]$ npm run start
> elasticsearch-head@0.0.0 start /home/es/elasticsearch-head-master
> grunt server
Running "connect:server" (connect) task
Waiting forever...
Started connect web server on http://node1:91005.3访问9100端口
如果出现“未连接”，请修改localhost为node1，然后单击“连接”按钮
6 简单应用
6.1创建索引
[root@node1 ~]# curl -XPUT node1:9200/test
{"acknowledged":true,"shards_acknowledged":true,"index":"test"}[root@node1 ~]#
