How to mount CD/DVD ROM on CentOS / RHEL Linux step by step instructions

Locate CD/DVD block device: First we need to find a correct CD/DVD block device. To do this execute a command blkid as root user:

# blkid 

/dev/sda1: UUID="d9704e79-b05e-4c9d-b94a-09643ba70592" TYPE="xfs" PARTUUID="83288aa1-01"

/dev/sda2: UUID="21291424-9d73-4c7e-b039-ce311702c75f" TYPE="swap" PARTUUID="83288aa1-02"

/dev/sr0: UUID="2019-08-15-21-52-52-00" LABEL="CentOS-8-BaseOS-x86_64" TYPE="iso9660" PTUUID="3e04f576" PTTYPE="dos"

Take a note of the relevant block device eg. /dev/sr0 and optionally also take a note of the shown UUID 2019-08-15-21-52-52-00.

Create Mount Point:
Mount point will be a directory where you wish to mount your CD/DVD drive. It can be any arbitrary directory. For example in this case we will be using /media/iso as a directory mount point:

# mkdir /media/iso 

Mount CD/DVD:
We are now ready to mount CD/DVD by using the mount command:

# mount /dev/sr0 /media/iso/

mount: /media/iso: WARNING: device write-protected, mounted read-only.

At this point you should be able to access all files on your CD/DVD drive:

   $ ls /media/iso/

   AppStream  BaseOS  EFI  images  isolinux  media.repo  TRANS.TBL

Permanent CD/DVD mount:

To mount your drive permanently edit /etc/fstab by adding the following line. Change UUID and mount point to fit your environment:

UUID=2019-08-15-21-52-52-00             /media/iso                iso9660 ro,user,auto  0 0

Once ready mount the CD/DVD by:

   # mount /media/iso/
