1.蛋疼的ElasticSearch(一)之安装ElasticSearch
2.蛋疼的ElasticSearch(二)之配置ElasticSearch Head插件
配置elasticsearch-analysis-ik
1.下载https://github.com/medcl/elasticsearch-analysis-ik
2.解压 elasticsearch-analysis-ik-master.zip
3.mvn clean package

4.打开编译target\releases，解压压缩包，然后进入解压的压缩包里面可以看到几个jar包和配置文件

5.在plugins目录下创建目录ik

6.启动elasticsearch，测试分词是否生效。

elasticsearch集群搭建
elasticsearch-master(192.168.10.6:9200)，配置如下：
#action.destructive_requires_name: true
node.max_local_storage_nodes: 256
#集群的名字
cluster.name: mayday
node.master: true
#节点名字
node.name: node-master
#数据存储目录(多个路径)
path.data: /home/elasticsearch/data
#日志目录
path.logs: /home/elasticsearch/logs
#本机的ip地址
network.host: 192.168.10.6
#设置集群中master节点的初始列表，可以通过这些节点来自动发现新加入集群的节点
discovery.zen.ping.unicast.hosts: ["192.168.10.6:9300","192.168.10.6:9301","192.168.10.6:9302"]
#设置节点间tcp端口(集群)，默认9300
transport.tcp.port: 9300
#监听端口(默认)
http.port: 9200
#增加参数，使head插件可以访问es
http.cors.enabled: true
http.cors.allow-origin: "*"
discovery.zen.ping_timeout: 200s
discovery.zen.fd.ping_timeout: 200s
discovery.zen.fd.ping_interval: 30s
discovery.zen.fd.ping_retries: 5
elasticsearch-slave01(192.168.10.6:9201)，配置如下：
#action.destructive_requires_name: true
node.max_local_storage_nodes: 256
#集群的名字
cluster.name: mayday
#节点名字
node.name: node-slave01
#数据存储目录(多个路径)

transport.tcp.port: 9301
#监听端口(默认)
http.port: 9201
#增加参数，使head插件可以访问es
http.cors.enabled: true
http.cors.allow-origin: "*"
elasticsearch-slave02(192.168.10.6:9202)，配置如下：
node.max_local_storage_nodes: 256
#action.destructive_requires_name: true
#集群的名字
cluster.name: mayday
#节点名字
node.name: node-slave02
#数据存储目录(多个路径)
path.data: /home/elasticsearch/data
#日志目录
path.logs: /home/elasticsearch/logs
#本机的ip地址
network.host: 192.168.10.6
#设置集群中master节点的初始列表，可以通过这些节点来自动发现新加入集群的节点
discovery.zen.ping.unicast.hosts: ["192.168.10.6:9300","192.168.10.6:9301","192.168.10.6:9302"]
#设置节点间tcp端口(集群)，默认9300
transport.tcp.port: 9302
#监听端口(默认)
http.port: 9202
#增加参数，使head插件可以访问es
http.cors.enabled: true
http.cors.allow-origin: "*"
启动三台elasticsearch，测试是否成功。

查看log日志，可以发现elasticsearch-master已经找到了elasticsearch-slave01和elasticsearch-slave02节点了，彼此建立了连接。
