Setting up RHEL Repo and WKMS

Notice
  • If the user created 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 Subnet where external access is restricted.
    Since the SCP RHEL Repository synchronizes with each Region Local Repository according to the internal schedule, it is recommended to switch to an external Public Mirror site to quickly apply the latest patches.

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 utilizing the RHEL Repository provided by SCP.
SCP provides the latest version of the repository for the given major version by default. To set up the RHEL repository, follow the steps below.

  1. Using the root user of the Virtual Server’s OS, use the cat command to check 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. repo configuration check (RHEL8)
    Color mode
    cat /etc/yum.repos.d/scp.rhel9.repo
    cat /etc/yum.repos.d/scp.rhel9.repo
    Code block. repo configuration check (RHEL9)

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