推荐答案
看起来你的文件夹没有正确的读/写权限。
Looks like your folder does not have the correct read/write permissions.
尝试授予读写访问到所有用户问题的目录,例如:
Try granting read-write access to all users to the directory in question, e.g.:
sudo chmod -R ugo+rw /mnt/my-address
如果你用不授予写权限的一切,你可以微调的权限,所有权和组打球,但我需要更多的信息关于您的设置,以帮助你这一点。
If you are uncomfortable with granting write permissions to all, you could fine tune the permissions by playing with ownership and groups, but I would need more info about your setup to help you with that.
修改:如果EC2用户是唯一一个需要访问,你可以改变目录的所有权给用户,然后授予仅他访问:
Edit: if the ec2-user is the only one needing access, you could change the ownership of the directory to that user and then grant access to only him:
sudo chown -R ec2-user:ec2-user /mnt/my-address
sudo chmod -R u+rw,go-rw /mnt/my-address
