多节点集群搭建

一、参考

集群安全配置功能大升级，单机模拟运行 Elasticsearch 8.1.2 三节点集群

使用 rpm/deb 软件包安装 Elasticsearch 8.1.0

二、部署

  ⁃ Create an enrollment token with `bin/elasticsearch-create-enrollment-token -s node`.
  ⁃ Uncomment the transport.host setting at the end of config/elasticsearch.yml.
  ⁃ Restart Elasticsearch.
• On other nodes:
  ⁃ Start Elasticsearch with `bin/elasticsearch --enrollment-token <token>`, using the enrollment token that you generated.
