How to Create Yum Repository from CDROM Media

In this guide, we will walk you through the process of installing or updating Redhat RPM packages from a locally mounted CDROM. This tutorial is particularly useful if you’re looking to install Redhat 5 packages. We will break down the process into easy-to-follow steps, ensuring you can successfully create a Yum repository from CDROM media.

Now, let’s get started with our tutorial on creating a Yum repository from CDROM media.

Step 1: Mount the CDROM Media

The first step in this process is to mount the CDROM media. This can be done by executing the following command:

# mount /dev/hdc /media

This command mounts the CDROM media to the /media directory.

Step 2: Create local.repo in yum.repos.d

Next, navigate to the /etc/yum.repos.d directory using the ‘cd’ command:

# cd /etc/yum.repos.d

Once you’re in the correct directory, create a new file named local.repo:

# vi local.repo

In the local.repo file, add the following lines:

[RHEL-5-Repository]
name=RHEL5 repository
baseurl=file:///media/Server
enabled=1
gpgcheck=0

This sets up the repository for the Redhat 5 packages.

Step 3: Install or Update Using Yum Command

After saving the local.repo file, you can start installing or updating packages using the yum command.

Commands Mentioned

• mount /dev/hdc /media – This command mounts the CDROM media to the /media directory.
• cd /etc/yum.repos.d – This command navigates to the /etc/yum.repos.d directory.
• vi local.repo – This command creates a new file named local.repo.

FAQ

1. What is the purpose of mounting the CDROM media?

   Mounting the CDROM media allows the system to access the data contained on the CDROM. It essentially makes the CDROM’s content available in the system’s directory tree, specifically in the /media directory in this case.

2. Why do we need to create a local.repo file?

   The local.repo file is created to define the repository from which the Yum package manager can install or update packages. It contains the necessary configuration for accessing the Redhat 5 packages from the mounted CDROM.

3. What does the yum command do?

   The yum command is used by the Yum package manager to install, update, or remove software packages on Linux systems. After setting up the local repository, you can use the yum command to install or update the Redhat 5 packages from the mounted CDROM.

4. What does the ‘gpgcheck=0’ line mean in the local.repo file?

   The ‘gpgcheck=0′ line in the local.repo file disables the GPG signature check for the packages. This means that yum will not verify the signature of the packages before installing them. It’s generally recommended to enable GPG check to ensure the packages’ authenticity and integrity, but in this case, it’s assumed that the packages on the CDROM are trusted.

5. What is the purpose of the ‘enabled=1’ line in the local.repo file?

   The ‘enabled=1’ line in the local.repo file indicates that the repository is enabled. This means that yum will use this repository when installing or updating packages. If you set ‘enabled=0’, yum will ignore this repository.
