Configure RHEL Repo and WKMS

information
  • If a user creates RHEL and Windows Server prior to August 2025 via the Samsung Cloud Platform Console, they need to modify the RHEL Repository and WKMS (Windows Key Management Service) settings.
  • The SCP RHEL Repository is a repository provided by SCP to support user environments such as VPC Private Subnets where external access is restricted.
    Since the SCP RHEL Repository synchronizes with each Region Local Repository according to an internal schedule, it is recommended to switch to an external public mirror site to apply the latest patches quickly.

RHEL Repository Configuration Guide

In Samsung Cloud Platform, when using RHEL, you can install and download the same packages as the official RHEL Repository by using the RHEL Repository provided by SCP.
SCP provides the latest repository for the given major version by default. To configure the RHEL repository, follow the steps below.

  1. As the root user on the Virtual Server, use the cat command to verify the /etc/yum.repos.d/scp.rhel8.repo or /etc/yum.repos.d/scp.rhel9.repo settings.

    Color mode
    cat /etc/yum.repos.d/scp.rhel8.repo
    cat /etc/yum.repos.d/scp.rhel8.repo
    Code block. Verify repo configuration (RHEL8)
    Color mode
    cat /etc/yum.repos.d/scp.rhel9.repo
    cat /etc/yum.repos.d/scp.rhel9.repo
    Code block. Verify repo configuration (RHEL9)

    • When checking the configuration file, the following result is displayed.
