在这个链接里找到了解决方案：
:: Set Variable :: set key="C:CodeDKOMProlikeServicesapdis.pem" :: Remove Inheritance :: cmd /c icacls %key% /c /t /inheritance:d
:: Set Ownership to Owner :: cmd /c icacls %key% /c /t /grant %username%:F
:: Remove All Users, except for Owner :: cmd /c icacls %key% /c /t /remove Administrator "Authenticated Users" BUILTINAdministrators BUILTIN Everyone System Users
:: Verify :: cmd /c icacls %key%
之后使用脚本ssh -i sapdis.pem root@39.XX.XXX.142
