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 commandblkid
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 UUID2019-08-15-21-52-52-00
. - 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 themount
command:# mount /dev/sr0 /media/iso/ OR # mount /dev/cdrom /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/
