   cluster.name: qsearch
   node.name: qsearch-master
   node.data: false
   node.master: true
   path.data: /data/install/elastic/data
   path.logs: /data/install/elastic/logs
   network.host: 本机内网ip
   # 本机ip或其他集群中机器的ip，随便写几个就行，不用全写，只要有一台机连上，就# 能自动加入集群
   discovery.zen.ping.unicast.hosts: ['host1', 'host2', ...]
   # 防止脑裂
   discovery.zen.minimum_master_nodes: number of master-nodes / 2 + 1

2.配置client node
   cluster.name: qsearch
   node.name: qsearch-client
   node.data: false
   node.master: false
   path.data: /data/install/elastic/data
   path.logs: /data/install/elastic/logs
   network.host: 本机内网ip
   discovery.zen.ping.unicast.hosts: ['host1', 'host2', ...]

3.配置data node
   cluster.name: qsearch
   node.name: qsearch-data
   node.data: false
   node.master: false
   path.data: /data/install/elastic/data
   path.logs: /data/install/elastic/logs
   network.host: 本机内网ip
   discovery.zen.ping.unicast.hosts: ['host1', 'host2', ...]
   bootstrap.mlockall: true

系统配置

以下是data node必配，其他的参考：https://blog.csdn.net/iorichang/article/details/53840824

vim /etc/security/limits.conf
   elastic soft nofile 65536
   elastic hard nofile 65536
   elastic soft memlock unlimited
   elastic hard memlock unlimited

vim /etc/sysctl.conf
   vm.swappiness=1 # 关闭 swapping
   net.core.somaxconn=65535 # 上调端口的最大连接数
   vm.max_map_count=262144
   fs.file-max=518144

安装分词+拼音插件

源码编译安装：
1.安装maven
2.解压
elasticsearch-analysis-ik-6.2.4.source.zip
elasticsearch-analysis-pinyin-master.source.zip
3.进入解压目录，输入mvn clean package 编译
4.编译结果在:/target/releases/XXXX.zip
5.安装插件：elasticsearch-plugin install /target/releases/xxxx.zip
