一、简介
etcd is a strongly consistent, distributed key-value store that provides a reliable way to store data that needs to be accessed by a distributed system or cluster of machines. It gracefully handles leader elections during network partitions and can tolerate machine failure, even in the leader node
二、下载
官网地址：https://etcd.io/
点击quickStart
点击截图链接
下载最新windows版本即可
三、集群配置
属性配置文件可查看各版本的configuration.md文件，此处以3.4为例
https://github.com/etcd-io/etcd/tree/release-3.4/Documentation/op-guide
单节点集群配置，其他节点修改指定的几个变量即可
etcd1.bat（此处的配置是直接加在启动命令后，也可将配置写在指定的文件中–具体查看configuration.md）
-- On each etcd node, specify the cluster members
set TOKEN=token-01
set CLUSTER_STATE=new
set NAME_1=etcd1
set NAME_2=etcd2
set NAME_3=etcd3
set HOST_1=127.0.0.1:2379
set LISTEN_HOST_1=127.0.0.1:2380
set HOST_2=127.0.0.1:2479
set LISTEN_HOST_2=127.0.0.1:2480
set HOST_3=127.0.0.1:2579
set LISTEN_HOST_3=127.0.0.1:2580
set CLUSTER=%NAME_1%=http://%LISTEN_HOST_1%,%NAME_2%=http://%LISTEN_HOST_2%,%NAME_3%=http://%LISTEN_HOST_3%
-- Run this on each machine
-- node1
set THIS_NAME=%NAME_1%
set THIS_IP=%HOST_1%
set THIS_LISTEN_IP=%LISTEN_HOST_1%

四、验证
安装etcdmanager客户端
验证效果如下图
