搭建etcd单点

首先在github上下载最新的稳定的etcd

> [https://github.com/etcd-io/etcd/releases][https_github.com_etcd-io_etcd_releases]

下载完成后解压，安装即可。

然后解压并且配置环境变量
    unzip etcd-v3.8xx.zip
    
    mv etcd-v3.8 /usr/local
    
    设置环境变量
    export ETCD_HOME=/usr/local/etcd-v3.3.18-darwin-amd64
    export PATH=$ETCD_HOME:$PATH
    
    source /etc/profile

启动etcd

查看端口情况

etcd使用2379和2380作为端口

2379供服务端使用

2380共其他etcd节点使用

尝试写入和读取值

最后贴一下etcdctl 的参数和说明
