  • Elasticsearch6.0 安装elasticsearch-head插件

    es-head主要有三个方面的操作:

    1. 显示集群的拓扑,并且能够执行索引和节点级别操作
    2. 搜索接口能够查询集群中原始json或表格格式的检索数据
    3. 能够快速访问并显示集群的状态
    4. 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; 
      1. 请求方法(get、put、post、delete),查询json数据,节点和路径
      2. 支持JSON验证器
      3. 支持重复请求计时器
      4. 支持使用javascript表达式变换结果
      5. 收集结果的能力随着时间的推移(使用定时器),或比较的结果
      6. 能力图表转换后的结果在一个简单的条形图(包括时间序列)

    1、Elasticsearch6.0安装插件,这个和低版本安装不一样.需要先安装nodejs

    1)、下载npm包
    官网下载npm安装包,https://nodejs.org/en/
    [root@es-jypay-1 elasticsearch-head]# wget  https://nodejs.org/dist/v8.9.1/node-v8.9.1-linux-x64.tar.xz
    
    2)、解压,创建链接
    [root@es-jypay-1 elasticsearch-head]#tar xf node-v8.9.1-linux-x64.tar.xz
    [root@es-jypay-1 elasticsearch-head]#mv node-v8.9.1-linux-x64 /usr/local
    [root@es-jypay-1 elasticsearch-head]#ln -s /usr/local/node-v8.9.1-linux-x64/bin/node /usr/local/bin/node
    [root@es-jypay-1 elasticsearch-head]#ln -s /usr/local/node-v8.9.1-linux-x64/bin/npm /usr/local/bin/npm

    2、安装elasticsearch-head

    [root@es-jypay-1 ]#cd /usr/local
    [root@es-jypay-1 ]# git clone git://github.com/mobz/elasticsearch-head.git
    [root@es-jypay-1 ]# cd elasticsearch-head
    [root@es-jypay-1 elasticsearch-head]# npm install
    [root@es-jypay-1 elasticsearch-head]# npm install grunt --save-dev
    [root@es-jypay-1 elasticsearch-head]# rm -f /usr/local/bin/grunt
    [root@es-jypay-1 elasticsearch-head]# ln -s /usr/local/elasticsearch-head/node_modules/grunt/bin/grunt /usr/local/bin/grunt
    
    出现如下错误,需要安装缺少的包:
    
    [root@es-jypay-1 elasticsearch-head]# /usr/share/elasticsearch/plugins/elasticsearch-head/node_modules/grunt/bin/grunt server
    >> 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.
    
    安装方法如下:
    
    [root@es-jypay-1 elasticsearch-head]# npm install grunt-contrib-clean -registry=https://registry.npm.taobao.org 
    [root@es-jypay-1 elasticsearch-head]# npm install grunt-contrib-concat -registry=https://registry.npm.taobao.org 
    [root@es-jypay-1 elasticsearch-head]# npm install grunt-contrib-watch -registry=https://registry.npm.taobao.org 
    [root@es-jypay-1 elasticsearch-head]# npm install grunt-contrib-connect -registry=https://registry.npm.taobao.org 
    [root@es-jypay-1 elasticsearch-head]# npm install grunt-contrib-copy -registry=https://registry.npm.taobao.org 
    [root@es-jypay-1 elasticsearch-head]# npm install grunt-contrib-jasmine -registry=https://registry.npm.taobao.org
    
    启动head插件:
    [root@es-jypay-1 elasticsearch-head]# grunt --gruntfile=/usr/share/elasticsearch/plugins/elasticsearch-head/Gruntfile.js server  --force &
     elasticsearch/plugins/elasticsearch-head/Gruntfile.js server --force
     (node:3719) ExperimentalWarning: The http2 module is an experimental API.
     Running "connect:server" (connect) task
     Waiting forever...
     Started connect web server on http://localhost:9100

    3、安装完成后,在网页浏览
