部署etcd

官网：https://etcd.io/docs/v3.5/install/
release版本链接：https://github.com/etcd-io/etcd/releases/

下载部署文件

参考release版本链接中的说明，拼装相应版本的下载地址：

wget https://github.com/etcd-io/etcd/releases/download/{ETCD_VER}/etcd-{ETCD_VER}-darwin-amd64.zip

如v3.5.12 版本:

wget https://github.com/etcd-io/etcd/releases/download/v3.5.12/etcd-v3.5.12-darwin-amd64.zip

启动服务

将zip包解压出来，进入目录查看文件。

localhost:etcd xxx$ unzip etcd-v3.5.12-darwin-amd64.zip

运行启动命令

localhost:etcd-v3.5.12-darwin-amd64 xxx$ nohup ./etcd &
[1] 53092
localhost:etcd-v3.5.12-darwin-amd64 xxx$ appending output to nohup.out

命令行使用

1. put

   localhost:etcd-v3.5.12-darwin-amd64 xxx$ ./etcdctl put name cloud
   OK
   

2. get

   localhost:etcd-v3.5.12-darwin-amd64 xxx$ ./etcdctl get name
   name
   cloud
   

3. del

   localhost:etcd-v3.5.12-darwin-amd64 xxx$ ./etcdctl del name
   1
   

4. watch
   先执行watch，此时命令行会挂起， 等待watch的信息返回

   localhost:etcd-v3.5.12-darwin-amd64 xxx$ ./etcdctl watch name

   另外再开一个命令行窗口，执行put 命令，watch窗口会显示put的信息
   新窗口:

   localhost:etcd-v3.5.12-darwin-amd64 xxx$ ./etcdctl put name cloud
   OK
   

   watch窗口：

   localhost:etcd-v3.5.12-darwin-amd64 xxx$ ./etcdctl watch name
   PUT
   name
   cloud

   新窗口`再执行del命令:

   localhost:etcd-v3.5.12-darwin-amd64 xxx$ ./etcdctl del name
   1
   

   watch窗口也会显示del信息：

   localhost:etcd-v3.5.12-darwin-amd64 xxx$ ./etcdctl watch name
   PUT
   name
   cloud
   DELETE
   name

5. lease

   localhost:etcd-v3.5.12-darwin-amd64 xxx$ ./etcdctl lease grant 120
   lease 694d8dd00386a80a granted with TTL(120s)
   localhost:etcd-v3.5.12-darwin-amd64 xxx$ ./etcdctl put name cloud --	lease="694d8dd00386a80a"
   OK
   

brew 安装etcd

安装etcd

brew install etcd

运行 etcd
安装完后，会有相关提示，推荐使用 brew services 来管理这些应用。

brew services 常用的操作:

# 查看当前应用列表
brew services list# 启动某个应用
brew services start {serviceName}# 停止某个应用
brew services stop {serviceName}

以etcd为例：

#安装etcd 
brew install etcd#启动etcd
brew services start {serviceName}
