[qun@cluster-master ~]$ cat /etc/sysctl.conf
# sysctl settings are defined through files in
# /usr/lib/sysctl.d/, /run/sysctl.d/, and /etc/sysctl.d/.
#
# Vendors settings live in /usr/lib/sysctl.d/.
# To override a whole file, create a new file with the same in
# /etc/sysctl.d/ and put new settings there. To override
# only specific settings, add a file with a lexically later
# name in /etc/sysctl.d/ and put new settings there.
#
# For more information, see sysctl.conf(5) and sysctl.d(5).

分发安装文件
scp -r elasticsearch-6.5.1 qun@cluster-slave1:~/
scp -r elasticsearch-6.5.1 qun@cluster-backup:~/
修改cluster-slave1和cluster-backup配置文件
cluster-slave1节点
vi elasticsearch.yml
node.name: node2
cluster-backup节点
vi elasticsearch.yml
node.name: node3
启动
在三个节点分别执行
bin/elasticsearch &
配置elasticsearch-head
下载配置nodejs

下载安装启动elasticsearch-head
git clone https://github.com/mobz/elasticsearch-head.git
cd elasticsearch-head
npm install -g grunt-cli
npm install
grunt server
查看elasticsearch-head web 控制台
http://192.168.120.5:9100/
创建一个index，这里使用的是google 浏览器的postman插件；
这里需要注意的是，虽然我们指定http://192.168.120.5:9200/customer?pretty发送Put请求创建Index，其实只要指定集群中任何一台节点都可以
查看集群状态
插入数据
执行sql查询
