Before you begin

If you are upgrading to Experience Portal 8.x from Experience Portal 6.x or 7.x, you must do a fresh installation of a supported version of Red Hat Enterprise Linux Server.

Procedure

    The system displays the Welcome to Red Hat Enterprise Linux screen.

  2. Select the Install Red Hat Enterprise Linux option.
  3. Select English as the language to use during the installation process.
  4. Select the U.S. English keyboard option.
  5. Select Installation Destination and select the disk to install Red Hat Enterprise Linux..
  6. Select Network and Host name.
  7. Enter the host name and select Apply.
    Note:

    All network configuration including the hostname and IP (and other properties specified in steps 7 and 8) must remain the same.

  8. To configure the network:
    1. Ensure that eth0/ens192, the main Ethernet interface, is enabled.
    2. On the IPv4 Settings tab, configure the following settings using the values specified on the installation worksheet:

      • Static IP address

      • Netmask

      • Gateway

      • DNS servers

      • Search domains

  9. Enter the applicable timezone.
  10. Select Begin Installation.

    1. Accept the License Agreement and Finish Configuration (RHEL 8.x).
    2. Set the system clock.
    3. Create a non-root account. Ensure that you use the value that you have specified in the installation worksheet.
      Note:

      After the Experience Portal software is installed, use a non-root account to log in and then change to root account by using the su — command.
