index.number_of_shards: 默认的配置是把索引分为5个分片
index.number_of_replicas:设置每个index的默认的冗余备份的分片数，默认是1
network.bind_host: 设置可以访问的ip,可以是ipv4或ipv6的，默认为0.0.0.0，这里全部设置通过
network.publish_host:设置其它结点和该结点交互的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
http.cors.enabled: 是否允许跨域REST请求
http.cors.allow-origin: 允许 REST 请求来自何处
node.master: true 配置该结点有资格被选举为主结点（候选主结点），用于处理请求和管理集群。如果结点没有资格成为主结点，那么该结点永远不可能成为主结点；如果结点有资格成为主结点，只有在被其他候选主结点认可和被选举为主结点之后，才真正成为主结点。
node.data: true 配置该结点是数据结点，用于保存数据，执行数据相关的操作（CRUD，Aggregation）；
