弹性搜索节点未加入集群

Question

我创建了具有 3 个节点、两个符合条件的主节点和一个数据节点的弹性搜索集群， 以下是.yml文件配置（注释设置省略）

问题是所有节点都没有创建集群，

主节点和数据节点02组成一个集群，数据节点01分别创建一个单独的集群。

我是否遗漏了 .yml 配置中的任何内容？

调用http://(master_node_ip):9200/_cluster/state?pretty

返回

并在 data_node_01 上调用集群 api 返回

有人可以帮忙吗？

弹性搜索中的脑裂问题

更新：

你的问题是discovery.zen.minimum_master_nodes: 你没有设置那个值，默认是 1，

在您的情况下，合格的主节点是 2 个，并且只需要一个节点来选举主节点，

master_node 和 data_node_01 将自己分配为主节点 所以脑裂
