   yum list docker-ce --showduplicates |sort -r
   

   

4. 指定版本安裝Docker

   docker version
   

6. 安裝Docker-compose

   curl -L "https://github.com/docker/compose/releases/download/1.22.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
   

7. 給Docker-compose賦予可執行許可權

   chmod +x /usr/local/bin/docker-compose
   

8. 檢視Docker是否安裝成功

   docker-compose -v
   

9. 啟動\重啟\停止Docker

   #啟動
   systemctl start docker
   # 重啟
   systemctl restart docker
   # 停止
    
   
   systemctl stop docker
   

10. 將Docker加入到開機啟動項
