操作系统设置

There are two important discovery and cluster formation settings that should be configured before going to production so that nodes in the cluster can discover each other and elect a master node:discovery.seed_hosts,cluster.initial_master_nodes
network.host: 0.0.0.0 discovery.seed_hosts: ["10.10.50.217", "10.10.50.218", "10.10.50.219"] cluster.initial_master_nodes: ["esclus-01", "esclus-02", "esclus-03"]
注意事项,参数 cluster.initial_master_nodes 中的参数要与节点名称对应。
