How to use linux virtual optical drive?

Using a virtual optical drive under Linux actually does not require any virtual optical drive software. You can use the mount command to complete it.

1. Make the CD into an iso file

cp /dev/cdrom XXXXX.iso

XXXXX.iso is an image file named for you. After executing this command, the entire disc can be made into an iso file. You can add the path before XXXXX.iso

.

2. Load the iso file on the hard disk to the CD (or virtual CD-ROM drive).

mount -t iso9660 -o loop /*/XXXXX.iso /mnt/iso

3. If you are installing files provided by the system disk, such as adding or deleting programs, the system may prompt you to insert the CD, but we do not have a CD, only a mirror, what should we do?

For Redhat, first mount iso, and then execute

redhat-install-packages --isodir=/mnt/iso

4. General virtual optical drive

Use losetup to check the usage of the loop device, and use losetup -f to find the first available device.

rm -rf /dev/cdrom #删除光驱
ln /dev/loop7 /dev/cdrom
losetup /dev/loop7 /*/XXXXX.iso
mount /dev/cdrom /mnt/cdrom

Then you look at the iso file, has it become a virtual optical drive?

Cancel this optical drive:

losetup -d /dev/loop7

If you change the disk:

Just transfer the iso association to /dev/loop

losetup /dev/loop7 /*/XXXXX.iso
