Guided Exercise: Install Red Hat Enterprise Linux

In this exercise, you reinstall one of your servers with a minimal installation of Red Hat Enterprise Linux.

Outcomes

  • Manually install Red Hat Enterprise Linux 9.

As the student user on the workstation machine, use the lab command to prepare your system for this exercise.

This command prepares your environment and ensures that all required resources are available.

[student@workstation ~]$ lab start installing-install

Instructions

  1. Access the servera console and reboot the system into the installation media.

    1. Locate the servera console icon in your classroom environment. Open the console.

    2. To reboot, send Ctrl+Alt+Del to your system by using the relevant keyboard, virtual, or menu entry.

    3. When the boot loader menu appears, select the Install Red Hat Enterprise Linux 9 menu entry.

  2. Keep the default selected language and click Continue.

      Gateway 172.25.250.254
      DNS servers 172.25.250.254

      Note

      Because Red Hat Enterprise Linux is already installed on the servera.lab.example.com machine, the values for each of the required fields exist. For a clean server, you must complete this information.

    4. Click Save to save the network configuration, and then click Done.

  4. Click Installation Source to configure the network installation source.

    1. Select the On the network option.

    1. Select the vda disk and then click Done.

    2. On the next page, click Reclaim space.

      The /dev/vda disk already has partitions and file systems from the previous installation. With this selection, you can wipe the disk for the new installation.

    3. Click Delete all, and then click Reclaim space.

  6. Click Software Selection, select Minimal Install from the Base Environment list, and then click Done.

  7. Set redhat as the password for the root user.

    1. Click Root Password and enter redhat in the Root Password field.

    5. Enter student in the Confirm password field.

    6. Click the Done button twice because the password fails the dictionary check.
