1. 解压

unzip elasticsearch-head-master.zip

1. 安装node和Grunt环境
   
   • 下载node: https://npm.taobao.org/mirrors/node/latest-v4.x/node-v4.4.7-linux-x64.tar.gz
   • 解压并配置环境变量vim /etc/profile

export NODE_HOME=/usr/local/node-v4.4.7-linux-x64
export PATH=$PATH:$NODE_HOME/bin
export NODE_PATH=$NODE_HOME/lib/node_modules
 
 

 
 

• 刷新环境变量：source /etc/profile
• 安装grunt命令行工具grunt-cli

npm install -g grunt-cli
 
 

 
 

• 安装grunt及其插件

npm install grunt --save-dev
 
 

 
 

• 验证安装是否成功:

grunt -version
 
 

 
 

1. 重命名为elasticsearch-head
2. 配置连接信息：进入elasticsearch-head/，运行vi Gruntfile.js来修复如下配置（ip 和 端口号）

    connect: {
            server: {
                options: {
                    port: 9100,
                    hostname: "0.0.0.0",
                    base: '.',
                    keepalive: true
                }
            }
        }
 
 

 
 

1. 保存后配置防火墙，开放9100端口，在控制台输入

firewall-cmd --zone=public --add-port=9100/tcp --permanent

firewall-cmd --reload
 
 

 
 

1. 修改elasticsearch服务器的elasticsearch.yml文件，使得head插件可以连接到es服务器，增加以下两个配置（跨域访问）


http.cors.enabled: true
http.cors.allow-origin: "*"
 
 

 
 

1. 重启elastic 进入elasticsearch-head安装目录里elasticsearch-head/ 运行grunt server来启动head服务

grunt server 
 
 

 
 

会出现下面的错误：

root@931a920a04b6:/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.

需要安装这些缺失的node modules, 注意需要回到elasticsearch_head目录下安装，

npm install grunt-contrib-clean grunt-contrib-concat grunt-contrib-watch grunt-contrib-connect grunt-contrib-copy grunt-contrib-jasmine

再次运行grunt server

输出以下信息证明启动成功

Running "connect:server" (connect) task
Waiting forever...
