What are the steps to mount a DVD drive in CentOS 7?

To mount a CD drive, follow these steps:

1. Firstly, make sure that a CD or DVD drive is already inserted into the CentOS 7 server.
2. Create a directory for mounting the CD-ROM, you can choose any directory, such as /mnt/cdrom:

sudo mkdir /mnt/cdrom

1. Next, use the following command to mount the CD-ROM to the created directory:

sudo mount /dev/cdrom /mnt/cdrom

If the system prompts that /dev/cdrom cannot be found, you can try the following command:

sudo mount /dev/sr0 /mnt/cdrom

1. After the mounting is completed, you can view the files in the CD-ROM by accessing the /mnt/cdrom directory.
2. You can use the following command to eject the CD-ROM drive when you no longer need to access its contents:

sudo umount /mnt/cdrom

This completes the steps of mounting and unmounting a CD drive on CentOS 7.
