**elasticsearch.yml配置文件详细说明：**

 <tbody> 
  <tr> 
   <td>cluster.name</td> 
   <td>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。</td> 
  </tr> 
  <tr> 
   <td>node.name</td> 
   <td>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。</td> 
  </tr> 
  <tr> 
   <td>node.master</td> 
   <td>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。</td>

    # 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
    http.cors.allow-origin: "*"
    # 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

    #
    # Use a descriptive name for the node:
    #

    # Make sure that the heap size is set to about half the memory available

    # Elasticsearch performs poorly when the system is swapping the memory.

    # --------------------------------- Discovery ----------------------------------

    # For more information, consult the discovery and cluster formation module documentation.

    #
    # Block initial recovery after a full cluster restart until N nodes are started:

    #
    # For more information, consult the gateway module documentation.

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**）
