2、解决办法

本质原因是elasticsearch.yml文件的参数配置不正确。由于自己检查不仔细，花了很长时间没有发现参数错误。
后来才发现是一个低级错误：3个节点的Elasticsearch集群中，elastic1节点的配置文件elasticsearch.yml的IP写错啦，IP地址本应是192.168.12.160，我写成了192.168.12.158啦。

node.name和network.host的值对应，保证正确：

  1. #当前节点名
  2. node.name: elastic1
  4. #配置当前结点绑定的IP地址，默认为0.0.0.0
  5. network.host: 192.168.12.160
