注意事项
1）版本不同，集群配置方法不同。例如 Elasticsearch 6.8.6 与 7.6.2 的集群配置方法是不同的。
第一步、服务搭建
跳过服务部署步骤，详细参考 Elasticsearch on CentOS 笔记。
第二步、调整配置
修改每台主机的/etc/elasticsearch/elasticsearch.yml文件，修改以下地方：
# 设置集群的名称
cluster.name: production-elasticsearch-cluster
# 设置节点的名称，取当前主机名。
node.name: ${HOSTNAME}
# 设置集群节点
discovery.zen.ping.unicast.hosts: ["10.0.0.1", "10.0.0.2", "10.0.0.3"]
第三步、重启服务
重启每台主机的 Elasticsearch 服务。
第四步、查看状态
执行curl -s http://ipaddress:9200/_cluster/state/?pretty | less命令，如果产生类似如下输出，则表示集群正常：
{
"cluster_name" : "elasticsearch-cluster",
"cluster_uuid" : "Mq7wyMd9Rw2nMQHhrPB-PA",
"version" : 13,
"state_uuid" : "ZnWe0IL_TRiH1hgwQSEz-g",
