我正在寻找设置自动电子商务在特定的时间间隔内(比如说每周一次)进行快照,为此我进行了 Google,发现可以使用 shell 脚本完成此任务,并且在这关联。

但是当我在终端上运行它时,它显示以下错误。
由于我是这方面的新手,所以解决这个问题有点不方便。请提出解决方案,我几天前就开始解决这个问题了。
答案1
我按照以下步骤解决了它。
- 创建 /var/log/volumes-list 并在其中写入 volume-id:Volume-name。
- 使用此安装 AWS CLI关联。
- 将 /usr/local/bin/aws 更改为 /home/centos/.local/bin/aws (就我而言)。
- 使用以下命令运行它。
脚本文件
它非常有效。
