安装Elasticsearch head

Elasticsearch head 是图形化界面管理ES的nodejs的web程序

安装步骤

下载插件

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

elasticsearch-head-master.zip

nodejs官网下载安装包

https://nodejs.org/dist/

node-v6.9.2-linux-x64.tar.xz

将elasticsearch-head-master.zip和node-v6.9.2-linux-x64.tar.xz都导入到linux的/opt/software目录
安装nodejs

[atguigu@hadoop102 software]$ tar -zxvf node-v6.9.2-linux-x64.tar.gz -C /opt/module/

配置nodejs环境变量

[root@hadoop102 software]# vi /etc/profile
export NODE_HOME=/opt/module/node-v6.9.2-linux-x64
export PATH=$PATH:$NODE_HOME/bin
[root@hadoop102 software]# source /etc/profile

查看node和npm版本

[root@hadoop102 software]# node -v
v6.9.2
[root@hadoop102 software]# npm -v
3.10.9

解压head插件到/opt/module目录下

[atguigu@hadoop102 software]$ unzip elasticsearch-head-master.zip -d /opt/module/

查看当前head插件目录下有无node_modules/grunt目录，没有则执行命令创建

[atguigu@hadoop102 elasticsearch-head-master]$ npm install grunt --save

安装head插件

[atguigu@hadoop102 elasticsearch-head-master]$ npm install -g cnpm --registry=https://registry.npm.taobao.org

安装grunt

[atguigu@hadoop102 elasticsearch-head-master]$ npm install -g grunt-cli

编辑Gruntfile.js

[atguigu@hadoop102 elasticsearch-head-master]$ vim Gruntfile.js
文件93行添加hostname:'0.0.0.0'
options: {
hostname:'0.0.0.0',
        port: 9100,
        base: '.',
        keepalive: true
      }

检查head根目录下是否存在base文件夹

没有：将 _site下的base文件夹及其内容复制到head根目录下
[atguigu@hadoop102 elasticsearch-head-master]$ mkdir base
[atguigu@hadoop102 _site]$ cp base/* ../base/

启动grunt server

[atguigu@hadoop102 elasticsearch-head-master]$ grunt server -d
Running "connect:server" (connect) task
[D] Task source: /opt/module/elasticsearch-head-master/node_modules/grunt-contrib-connect/tasks/connect.js
Waiting forever...
Started connect web server on http://localhost:9100

浏览器访问head插件

http://hadoop102:9100

启动集群插件后发现集群未连接

在/opt/module/elasticsearch-5.2.2/config路径下修改配置文件elasticsearch.yml，在文件末尾增加

[atguigu@hadoop102 config]$ pwd

/opt/module/elasticsearch-5.2.2/config

[atguigu@hadoop102 config]$ vi elasticsearch.yml

 

http.cors.enabled: true

http.cors.allow-origin: "*"

再重新启动elasticsearch

如何后台启动插件

后台运行

nohup grunt server &

关闭

好像停不了,网上说的ps -ef|grep head 找不到进程

可能遇到的问题

如果提示grunt的模块没有安装：
Local Npm module “grunt-contrib-clean” not found. Is it installed? 
Local Npm module “grunt-contrib-concat” not found. Is it installed? 
Local Npm module “grunt-contrib-watch” not found. Is it installed? 
Local Npm module “grunt-contrib-connect” not found. Is it installed? 
Local Npm module “grunt-contrib-copy” not found. Is it installed? 
Local Npm module “grunt-contrib-jasmine” not found. Is it installed? 
Warning: Task “connect:server” not found. Use –force to continue. 
执行以下命令： 
npm install grunt-contrib-clean -registry=https://registry.npm.taobao.org
npm install grunt-contrib-concat -registry=https://registry.npm.taobao.org
npm install grunt-contrib-watch -registry=https://registry.npm.taobao.org 
npm install grunt-contrib-connect -registry=https://registry.npm.taobao.org
npm install grunt-contrib-copy -registry=https://registry.npm.taobao.org 
npm install grunt-contrib-jasmine -registry=https://registry.npm.taobao.org
最后一个模块可能安装不成功，但是不影响使用
