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}
