Elasticsearch6.0 安装elasticsearch-head插件

Posted 2020-10-16

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/
[[email protected] 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
[[email protected] elasticsearch-head]#tar xf node-v8.9.1-linux-x64.tar.xz
[[email protected] elasticsearch-head]#mv node-v8.9.1-linux-x64 /usr/local
[[email protected] elasticsearch-head]#ln -s /usr/local/node-v8.9.1-linux-x64/bin/node /usr/local/bin/node
[[email protected] elasticsearch-head]#ln -s /usr/local/node-v8.9.1-linux-x64/bin/npm /usr/local/bin/npm

2、安装elasticsearch-head

[[email protected] ]#cd /usr/local
[[email protected] ]# git clone git://github.com/mobz/elasticsearch-head.git
[[email protected] ]# cd elasticsearch-head
[[email protected] elasticsearch-head]# npm install
[[email protected] elasticsearch-head]# npm install grunt --save-dev
[[email protected] elasticsearch-head]# rm -f /usr/local/bin/grunt
[[email protected] 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：

[[email protected] 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：

[[email protected] elasticsearch-head]# npm install grunt-contrib-clean -registry=https://registry.npm.taobao.org 
[[email protected] elasticsearch-head]# npm install grunt-contrib-concat -registry=https://registry.npm.taobao.org 
[[email protected] elasticsearch-head]# npm install grunt-contrib-watch -registry=https://registry.npm.taobao.org 
[[email protected] elasticsearch-head]# npm install grunt-contrib-connect -registry=https://registry.npm.taobao.org 
[[email protected] elasticsearch-head]# npm install grunt-contrib-copy -registry=https://registry.npm.taobao.org 
[[email protected] elasticsearch-head]# npm install grunt-contrib-jasmine -registry=https://registry.npm.taobao.org

启动head插件：
[[email protected] 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.
