elasticsearch.yml配置文件详细说明：
| 配置名字 | 说明 |
|---|---|
| cluster.name | 配置es的集群名称，默认是elasticsearch，es会自动发现在同一网段下的es，如果在同一网段下有多个集群，就可以用这个属性来区分不同的集群。 |
| node.name | 节点名，默认随机指定一个name列表中名字，该列表在es的jar包中config文件夹里name.txt文件中，其中有很多作者添加的有趣名字。 |
| node.master | 指定该节点是否有资格被选举成为master，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 | 指定该节点是否存储索引数据，默认为true。 |
| index.number_of_shards | 设置默认索引分片个数，默认为5片。 |
| index.number_of_replicas | 设置默认索引副本个数，默认为1个副本。 |
| network.bind_host | 设置绑定的ip地址，可以是ipv4或ipv6的，默认为0.0.0.0。 |
| network.publish_host | 设置其它节点和该节点交互的ip地址，如果不设置它会自动判断，值必须是个真实的ip地址。 |
| network.host | 这个参数是用来同时设置bind_host和publish_host上面两个参数。 |
| transport.tcp.compress | 设置是否压缩tcp传输时的数据，默认为false，不压缩。 |
| transport.tcp.port | 设置节点间交互的tcp端口，默认是9300。 |
| http.port | 设置对外服务的http端口，默认为9200。 |
| http.enabled | 是否使用http协议对外提供服务，默认为true，开启。 |
| discovery.zen.ping.multicast.enabled | 设置是否打开多播发现节点，默认是true。 |
| discovery.zen.ping.unicast.hosts | 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 |
1、es-node-master 节点

#必须指向主节点的节点名
cluster.initial_master_nodes: ["es-node-master"]
#culster transport port，节点相互通信端口号，默认9300
transport.tcp.port: 9300
#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

# 增加新的参数，这样head插件可以访问es，解决跨域访问问题（！！！必要）
http.cors.enabled: true

# 集群个节点IP地址，也可以使用els、els.shuaiguoxia.com等名称，需要各节点能够解析
#
# NOTE: Elasticsearch comes with reasonable defaults for most settings.
# Before you set out to tweak and tune the configuration, make sure you
# understand what are you trying to accomplish and the consequences.
#
# The primary way of configuring a node is via this file. This template lists
# the most important settings you may want to configure for a production cluster.
#
# Please consult the documentation for further information on configuration options:
# https://www.elastic.co/guide/en/elasticsearch/reference/index.html
#
# ---------------------------------- Cluster -----------------------------------
#
# Use a descriptive name for your cluster:
#
#cluster.name: my-application
#
# ------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
#
#node.name: node-1
#
# Add custom attributes to the node:
#
#node.attr.rack: r1
#
# ----------------------------------- Paths ------------------------------------
#
# Path to directory where to store the data (separate multiple locations by comma):
#
#path.data: /path/to/data
#
# Path to log files:
#
#path.logs: /path/to/logs
#
# ----------------------------------- Memory -----------------------------------
#
# Lock the memory on startup:
#
#bootstrap.memory_lock: true
#
# Make sure that the heap size is set to about half the memory available
# on the system and that the owner of the process is allowed to use this
# limit.
#
# Elasticsearch performs poorly when the system is swapping the memory.
#
# ---------------------------------- Network -----------------------------------
#
# Set the bind address to a specific IP (IPv4 or IPv6):
#
#network.host: 192.168.0.1
#
# Set a custom port for HTTP:
#
#http.port: 9200
#
# For more information, consult the network module documentation.
#
# --------------------------------- Discovery ----------------------------------
#
# Pass an initial list of hosts to perform discovery when this node is started:
# The default list of hosts is ["127.0.0.1", "[::1]"]
#
#discovery.seed_hosts: ["host1", "host2"]
#
# Bootstrap the cluster using an initial set of master-eligible nodes:
#
#cluster.initial_master_nodes: ["node-1", "node-2"]
#
# For more information, consult the discovery and cluster formation module documentation.
#
# ---------------------------------- Gateway -----------------------------------
#
# Block initial recovery after a full cluster restart until N nodes are started:
#
#gateway.recover_after_nodes: 3
#
# For more information, consult the gateway module documentation.
#
# ---------------------------------- Various -----------------------------------

# Require explicit names when deleting indices:

注意事项：es集群搭建的时候，如果第二个es服务器和第三个es服务器是复制本机上原有第一个es服务器，需要把es下data里面的内容清空（删除nodes文件夹）
