Mount CD from command line in RedHat

How to mount a CD in RedHat

First, we need to find out where the block device is;

(Option 1)

blkid

Which will give us something like;

Fig.1 (/dev/sr0)

The above is from RHEL 7.8 running virtually.

We can see in Fig.1 the iso9660 device is at /dev/sr0

(Option 2)

If we do not see /dev/sr0 as per Fig.1 then we can try:

ls /dev/cd* and if /dev/cdrom exists then we can continue.

We may also need to create a mount point, something like /mnt/iso is good and of course we can do this with;

mkdir /mnt/iso

We can also check the /etc/fstab entry for a mount point and if one exists,

we can try mount -a or mount --all

Finally, if there is not entry in fstab, we can mount the CD by mount device dir or in our example;

mount /dev/sr0 /mnt/iso

or from option 2;

mount /dev/cdrom /mnt/iso
