1. Environmental preparation
download nodejs
Nodejs official website download address https://nodejs.org/dist/
[root@localhost data]# wget https://nodejs.org/dist/v6.11.2/node-v6.11.2-linux-x64.tar.xz
2. Configure node environment variables
[root@node1 data]# xz -d node-v6.11.2-linux-x64.tar.xz
[root@node1 data]# tar -xvf node-v6.11.2-linux-x64.tar -C /usr/local/
[root@node1 data]# cd ~
[root@node1 ~]# ln -s /usr/local/node-v6.11.2-linux-x64/bin/node /usr/bin/node
[root@node1 ~]# ln -s /usr/local/node-v6.11.2-linux-x64/bin/npm /usr/bin/npm
[root@node1 ~]# node -v
v6.11.2
[root@node1 ~]# npm -v
3.10.10
[root@node1 ~]#
or:
root@node1 data]# vim /etc/profile Add the following 2 lines
export NODE_HOME=/usr/local/node-v6.11.2-linux-x64
export PATH=$PATH:$NODE_HOME/bin
root@node1 data]# source /etc/profile
[root@node1 data]# node -v
v6.11.2
[root@node1 data]# npm -v
3.10.10
4. Install grunt
If the production environment cannot be connected to the Internet to install grunt online, you can find a host that can connect to the Internet to configure node, and after installing grunt, package and upload the node_models in the elasticsearch-head directory.
[root@node1 ~]# npm install -g grunt-cli #After executing the command, the display is as follows:
/usr/local/node-v6.11.2-linux-x64/bin/grunt -> /usr/local/node-v6.11.2-linux-x64/lib/node_modules/grunt-cli/bin/grunt
/usr/local/node-v6.11.2-linux-x64/lib

再关联下grunt
[root@node1 ~]# ln -s /usr/local/node-v6.9.5-linux-x64/lib/node_modules/grunt-cli/bin/grunt /usr/bin/grunt
grunt是一个方便的构建工具，可以进行打包压缩、测试、执行等等的工作，5.x里的head插件就是通过grunt启动的；
#”-g”参数代表全局安装，一般安装到nodejs的”lib/node_modules”目录下；不带参数”-g”，则是本地安装，一般安装到运行npm命令时所在的目录，这里就需要安装到head插件目录；
#为grunt命令建软链接，方便全局执行，或加入环境变量；；
#如果镜像速度不理想，可提前切到国内的镜像，在安装grunt-cli前执行：npm config set registry https://registry.npm.taobao.org。
5、 下载elasticsearch-head
[root@node1 ~]# cd /usr/local
[root@node1 local]# git clone git://github.com/mobz/elasticsearch-head.git
[root@node1 local]# cd elasticsearch-head/
[root@node1 elasticsearch-head]# npm install
npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@^1.0.0 (node_modules/chokidar/node_modules/fsevents):
npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for [email protected]: wanted {"os":"darwin","arch":"any"} (current: {"os":"linux","arch":"x64"})
npm WARN [email protected] license should be a valid SPDX license expression
发现有3个警告信息，忽略即可，其中“npm WARN [email protected] license should be a valid SPDX license expression”警告信息可做如下处理：http://www.itdadao.com/articles/c15a1031952p0.html
即修改”./ elasticsearch-head”目录下“package.json”文件第19行的”"Apache2" “为"Apache-2.0"，涉及到开源软件与其他合作类软件的使用声明。
#如果没有全局安装grunt二进制程序，可在”elasticsearch-head”目录下执行”npm install grunt --save“ 或 ”npm install grunt-cli“。
6、配置head文件
[root@node1 elasticsearch-head]# cd _site/
[root@node1 _site]# cp app.js app.js.bak
[root@node1 _site]# vim app.js
#在4330行将原"http://localhost:9200"修改为"http://10.129.11.86:9200"，否则head插件不能获取节点状态信息。
[root@node1 elasticsearch-head]# cp Gruntfile.js Gruntfile.js.bak
[root@node1 elasticsearch-head]# vim Gruntfile.js
connect: {
server: {
options: {
hostname: '0.0.0.0',
port: 9100,
base: '.',
keepalive: true
}
}
}
# 在93行新增”hostname: '0.0.0.0', “，确保能被访问。
7、重启elasticsearch，并启动node 且验证，
[root@node1 elasticsearch-head]# nohup node_modules/grunt/bin/grunt server &exit
#Start the head plugin, you need to go to the elasticsearch-head directory
If you want to turn off the head plugin, use the Linux find process command:
ps aux|grep head
end process:
kill 进程号
