遠端同步

1. 將 deyu1 家目錄下的 cron.daily 目錄及目錄下的檔案，用戶及群組變更為 deyu1。

   [root@kvm5 ~]# chown deyu1.deyu1 -R /home/deyu1/cron.daily
   

2. 切換身份成 deyu1。

   [root@kvm5 ~]# su - deyu1
   Last login: Fri Oct 11 15:46:34 CST 2019 on pts/0
   

3. 將 cron.daily 目錄同步到遠端機器 kvm7.deyu.wang (192.168.122.7) 帳號 deyu1 的家目錄，其中選項 -z 是將資料壓縮再傳送。

   [deyu1@kvm5 ~]$ rsync -avzh cron.daily deyu1@kvm7.deyu.wang:
