一.介绍 head插件

head插件是用node.js开发的所以需要此环境

简单的说 Node.js 就是运行在服务端的 JavaScript。Node.js 是一个基于 Chrome V8 引擎的 JavaScript 运行环境。Node.js 使用了一个事件驱动、非阻塞式 I/O 的模型，使其轻量又高效。Node.js 的包管理器 npm，是全球最大的开源库生态系统。

二.下载软件包node.js和head插件：

https://nodejs.org/en/download/

https://github.com/mobz/elasticsearch-head

2.1 上传到服务器指定的目录下如图：

三.解压到指定文件夹以及配置环境变量：

3.1 解压到指定文件夹中：

[root@localhost es-plugs-head]# cp -r /opt/softpackagebyjurf/node-v10.15.3-linux-x64 .

[root@localhost es-plugs-head]# ls

node-v10.15.3-linux-x64[root@localhost es-plugs-head]# cp -r /opt/softpackagebyjurf/elasticsearch-head-master .

[root@localhost es-plugs-head]# ls

elasticsearch-head-master node-v10.15.3-linux-x64

3.2 配置node.js的环境变量

[root@localhost es-plugs-head]# vim /etc/profile #此操作使用root用户操作

export NODE_HOME=/opt/softpackagebyjurf/es-plugs-head/node-v10.15.3-linux-x64

export PATH=$PATH:$NODE_HOME/bin

export NODE_PATH=$NODE_HOME/lib/node_modules

配置后执行：source /etc/profile

[root@localhost es-plugs-head]# source /etc/profile

四.head的插件安装：

进入 elasticsearch-head-master目录：

#4.1 grunt插件的安装

[root@localhost es-plugs-head]# cd elasticsearch-head-master/

[root@localhost elasticsearch-head-master]# npm install -g grunt-cli

/opt/softpackagebyjurf/es-plugs-head/node-v10.15.3-linux-x64/bin/grunt -> /opt/softpackagebyjurf/es-plugs-head/node-v10.15.3-linux-x64/lib/node_modules/grunt-cli/bin/grunt

#4.3 给es的执行用户赋予head插件的权限

因为root用户拥有head插件目录的执行权限，现在赋予给es的操作用户elauser也具有head插件目录的操作权限，命令如下：

[root@localhost elasticsearch-head-master]# chown -R elauser:elagroup /opt/softpackagebyjurf/es-plugs-head/

#4.4 置修改Gruntfile.js

[root@localhost elasticsearch-head-master]# vim Gruntfile.js

connect: {

server: {

options: {

hostname: '0.0.0.0',

port: 9100,

base: '.',

keepalive: true

}

#4.5 置修改ip地址

修改连接地址：elasticsearch-head-master /_site/app.js

将localhost改为192.168.233.120

#4.6 修改elasticsearch.yml配置文件：（注意键值对后面的“：”加一空格）

http.cors.enabled: true

http.cors.allow-origin: "*"

五.head的启动：

进入elasticsearch-head-master目录下： cd elasticsearch-head-master

5.1 启动grunt server

#执行 grunt server

[root@localhost elasticsearch-head-master]# grunt server

Running "connect:server" (connect) task

Waiting forever...

Started connect web server on http://localhost:9100

#后台运行方式 grunt server & 后台启动head插件（加&设置为后台启动，不加ctrl+c退出时则关闭）

[root@localhost elasticsearch-head-master]# grunt server &

[1] 58893

[root@localhost elasticsearch-head-master]# Running "connect:server" (connect) task

Waiting forever...

Started connect web server on http://localhost:9100

5.2 启动es

启动es （必须用elauser用户）

[elauser@localhost bin]$ ./elasticsearch -d

[elauser@localhost bin]$ jps

58707 Elasticsearch

58731 Jps

[elauser@localhost bin]$

5.3 页面访问es

本机访问: http://localhost:9100

其他机器访问：http://192.168.233.120:9100

https://blog.csdn.net/qq_36697880/article/details/83011578 Linux安装elasticsearch6.X的head插件

六.自定义启动和关闭脚本程序：

6.1 自定义后台启动和关闭的脚本程序

ps -ef |grep grunt|awk '{print $2}'|sed -n '1p' |xargs kill -9

'{print $2}'：表示每行的第二列

sed -n '1p' ：多条数据，只取第一行，即第一条数据。

6.2 自定义启动脚本es-head-start.sh的内容：

#!/bin/bash

echo "START elasticsearch-head "

nohup grunt server &

exit

6.3 自定义启动脚本es-head-stop.sh的内容：

#!/bin/bash

echo "STOP elasticsearch-head "
