本文详细介绍了如何在单机环境中部署一个包含三个节点的etcd集群，包括配置文件的创建、节点启动以及状态检查。同时，文章还提供了etcd的数据备份和恢复流程，包括备份脚本的执行和数据导入，确保在必要时能够快速恢复集群状态。

etcd单机集群部署
下载etcd 二进制安装包。
https://github.com/etcd-io/etcd/releases

创建相关目录

mkdir –p /data/etcd/node1
mkdir –p /data/etcd/node2
mkdir –p /data/etcd/node3

在 /data/etcd/node1，/data/etcd/node2，/data/etcd/node3创建三个配置文件
node1.yml
name: node1
data-dir: /data/etcd/node1
listen-client-urls: 'http://192.168.73.222:9002'
advertise-client-urls: 'http://192.168.73.222:9002'

initial-cluster-token: etcd-cluster-1
initial-cluster-state: new

node2.yml
name: node2
data-dir: /data/etcd/node2

node3.yml
