Mount CD/DVD ROM on RHEL 7 Linux

       

Instructions

Locate Block device

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

# blkid
/dev/sda1: UUID="937c8752-0206-4c5a-a25f-63a187b1a749" TYPE="xfs"
/dev/sda2: UUID="fWxSbV-Y4mQ-CJbE-HUTb-XsnF-DsGB-1ThV6s" TYPE="LVM2_member"
/dev/sr0: UUID="2015-10-30-11-11-49-00" LABEL="RHEL-7.2 Server.x86_64" TYPE="iso9660" PTTYPE="dos"
/dev/mapper/rhel-root: UUID="63b73273-3de4-423d-9a85-8c99701fb137" TYPE="xfs"
/dev/mapper/rhel-swap: UUID="0f3f07ac-d817-4f2c-9b74-b7223b486605" TYPE="swap"
/dev/mapper/rhel-home: UUID="467a69d7-6fec-4a07-bec9-e1e9d7cb1ad8" TYPE="xfs"

Take a note of the relevant block device eg. /dev/sr0 and optionally also take a note of the shown UUID Take a note of the relevant block device eg. /dev/sr0 and optionally also take a note of the shown UUID 2016-10-19-18-32-06-.

Create a mount point

Next, create a new directory or use existing to be used as a mount point:

# mkdir /media/rhel

Permanent CD/DVD mount using fstab

The above will mount your CD/DVD ROM only temporarily. In order to make this mount permanent after reboot edit /etc/fstab configuration file by adding a following line replacing UUID to match your previous blkid command output:

UUID=2015-10-30-11-11-49-00             /media/rhel   iso9660 ro,user,auto  0 0
