白话Elasticsearch64-zen discovery集群发现机制
但是默认配置下，unicast是本机，也就是localhost，因此只能在一台机器上启动多个node来组成一个集群。 因此现在建议在生产环境中用unicast机制，提供一个es种子node作为中转路由节点就可以了。 ---- （1）ping ping是一个node用discovery机制来发现其他node的一个过程 （2）unicast unicast discovery集群发现机制是要求配置一个主机列表，用来作为 这就是基于gossip流言式通信协议的unicast集群发现机制。 ，首先通过network.host绑定到了非回环的ip地址，从而可以跟其他节点通信 （2）通过discovery.zen.ping.unicast.hosts配置了一批unicast中间路由的node
