Create Local YUM Repository from Systemd Mounted DVD on RHEL 7

We can mount DVDs/partitions using systemd.mount by writing a mount unit file.

Ensure that a RHEL7 DVD is inserted (or attached if using a VM).

Create a mountpoint:

# mkdir /mnt/rhel7dvd

Note that mount units must be named after the mountpoint directories they control. In our case, the mountpoint /mnt/rhel7dvd has to be configured in the file mnt-rhel7dvd.mount. The unit file name has to match the mountpoint path.

Here’s the context of the newly created file /etc/systemd/system/mnt-rhel7dvd.mount:

[Unit]
Description=rhel7dvd

[Mount]
What=/dev/cdrom
Where=/mnt/rhel7dvd

[Install]
WantedBy=multi-user.target

Reload the systemd daemon and start the unit:

# systemctl daemon-reload
# systemctl start mnt-rhel7dvd.mount
# systemctl enable mnt-rhel7dvd.mount

Create a Yum repo file /etc/yum.repos.d/rhel7dvd.repo with the following content:

[dvd]
name=rhel7 dvd
baseurl=file:///mnt/rhel7dvd
enabled=1
gpgcheck=1
gpgkey=file:///mnt/rhel7dvd/RPM-GPG-KEY-redhat-release

Verify:

# yum clean all && yum repolist
Cleaning repos: dvd
Cleaning up everything

dvd                                      rhel7 dvd                                     4,751

  1. Hi Tomas , just wanted to know what is the purpose of using a mount unit file instead of using normal mount command to mount the rhel7 DVD.
    Thanks.
