linux-permission-denied-问题，关联 mount, remount, cdrom

February 22, 2022

• 参考：
  • Kali Linux VM: Permission denied to run shell script, as root

permission denied 问题，可能是：

1. 文件没有执行权限
   解决： chmod a+x your-file

2. 挂载参数包含 noexec
   It might be that the /media/cdrom0 filesystem has the noexec flag set.
   执行 mount -v | grep cdrom0 看下挂载参数有么 noexec

   解决： 重新挂载， sudo mount -o remount,exec,ro /media/cdrom0
