# vi /usr/local/elasticsearch-6.2.3/config/elasticsearch.yml
http.cors.enabled: true
http.cors.allow-origin: "*"
node.master: true
node.data: true

重启：
# netstat -nlpt | grep 9200
tcp6 0 0 127.0.0.1:9200 :::* LISTEN 13803/java
tcp6 0 0 192.168.110.200:9200 :::* LISTEN 13803/java

# kill -9 13803
# /usr/local/elasticsearch-6.2.3/bin/elasticsearch -d

>下载head插件
# cd /tmp
# wget https://github.com/mobz/elasticsearch-head/archive/master.zip

>解压到/opt目录
[root@elk tmp]# unzip master.zip -d /opt/
[root@elk tmp]# ls /opt/
elasticsearch-head-master

>下载安装node
[root@elk tmp]# wget https://npm.taobao.org/mirrors/node/latest-v4.x/node-v4.4.7-linux-x64.tar.gz
[root@elk tmp]# tar -xf node-v4.4.7-linux-x64.tar.gz -C /opt/
[root@elk tmp]# ls /opt/
elasticsearch-head-master node-v4.4.7-linux-x64

>修改环境变量配置文件
# vi /etc/profile
export NODE_HOME=/opt/node-v4.4.7-linux-x64
export PATH=${PATH}:$NODE_HOME/bin
export NODE_PATH=$NODE_HOME/lib/node_modules

[root@elk ~]# source /etc/profile
[root@elk ~]# npm -v

[root@elk elasticsearch-head-master]# npm install -g grunt-cli
[root@elk elasticsearch-head-master]# grunt -version

>修改head插件源码/opt/elasticsearch-head-master/Gruntfile.js
# vi /opt/elasticsearch-head-master/Gruntfile.js
connect: {
