- 部署前各角色的分配
- 部署elasticsearch
- 环境部署
- 使用shell脚本一键部署第一台master
- 部署一台服务器上的其他三台elasticsearch
- 安装包地址
一、这里我们可以把elasticsearch的角色分为3种类型。
1.master节点
2.data（数据）节点
3.client（客户端、分发）节点
可以根据实际情况进行决定
二、根据流量或访问量配置client节点
三、elasticsearch部署集群时，master节点至少需要三台
注意：master节点需要为单数，否则第一个master节点不能进行选举，且master就作为主节点，不参与数据的保存的任务
