 cluster.name: ELK-elasticsearch  ##集群的名称
 node.name: node-1  ##节点名称,其余两个节点分别为node-2 和node-3
 node.master: true ##指定该节点是否有资格被选举成为master节点，默认是true，es是默认集群中的第一台机器为master，如果这台机挂了就会重新选举master
 node.data: true ##允许该节点存储数据(默认开启)
 path.data: /usr/local/elasticsearch/data  ##索引数据的存储路径
 path.logs: /usr/local/elasticsearch/logs  ##日志文件的存储路径
 bootstrap.mlockall: true ##设置为true来锁住内存。因为内存交换到磁盘对服务器性能来说是致命的，当jvm开始swapping时es的效率会降低，所以要保证它不swap
 network.host: 0.0.0.0  ##绑定的ip地址
 http.port: 9200 ##设置对外服务的http端口，默认为9200
 transport.tcp.port: 9300 ##设置节点间交互的tcp端口,默认是9300 
 discovery.zen.ping.unicast.hosts: ["172.17.120.11:9300", "172.17.120.12:9300", "172.17.120.13:9300"]  ##Elasticsearch将绑定到可用的环回地址，并将扫描端口9300到9305以尝试连接到运行在同一台服务器上的其他节点。这提供了自动集群体验，而无需进行任何配置。数组设置或逗号分隔的设置。每个值的形式应该是host:port或host（如果没有设置，port默认设置会transport.profiles.default.port 回落到transport.tcp.port）。请注意，IPv6主机必须放在括号内。默认为127.0.0.1, [::1]
 discovery.zen.minimum_master_nodes: 2 ##如果没有这种设置,遭受网络故障的集群就有可能将集群分成两个独立的集群 - 分裂的大脑 - 这将导致数据丢失
