Host RPMs on Apache Server

Set up an Apache HTTP server to host the Slurm RPM repository so that the OIM can download packages during cluster deployment.

Overview

After building Slurm RPMs (see Build Slurm Repository), you need to host them on an HTTP server accessible from the OIM. This guide uses Apache (httpd) to serve the RPMs as a YUM/DNF repository.

Prerequisites

  • Slurm RPMs are built and verified (see Build Slurm Repository).
  • The server on which you want to host the repository is accessible from the OIM.

Procedure

  1. Update system packages:

    Run on: repo server
    dnf update -y

  2. Install Apache:

    Run on: repo server
    dnf install -y httpd

  3. Install createrepo:

    Run on: repo server
    dnf install -y createrepo

  4. Start and enable Apache:

    Run on: repo server
    systemctl start httpd
systemctl enable httpd

  5. Verify the HTTP service status:

    Run on: repo server
    systemctl status httpd

    The status should be Active.

  6. Create a directory, copy the RPMs, and generate repository metadata:

    Run on: repo server
    mkdir -p /var/www/html/slurm_custom
cp /root/rpmbuild/RPMS/x86_64/slurm-*.rpm /var/www/html/slurm_custom/
cd /var/www/html/slurm_custom
createrepo .

    Note

    For aarch64 RPMs, create a separate directory:

    Run on: repo server
    mkdir -p /var/www/html/slurm_custom_aarch64
cp /root/rpmbuild/RPMS/aarch64/slurm-*.rpm /var/www/html/slurm_custom_aarch64/
cd /var/www/html/slurm_custom_aarch64
createrepo .

Custom Port (Optional)

If you want to host the repository on a custom port instead of the default port 80:

  1. Edit the Apache configuration:

    Run on: repo server
    vi /etc/httpd/conf/httpd.conf

    Find the Listen parameter and update the port:

    File: /etc/httpd/conf/httpd.conf
    #Listen 12.34.56.78:80
Listen 8080

  2. Restart Apache:

    Run on: repo server
    systemctl restart httpd
systemctl status httpd

Verification

  1. Verify the repository is accessible from the OIM:

    Run on: OIM host
    curl -s http://<repo-server-ip>/slurm_custom/repodata/repomd.xml | head

    If using a custom port:

    Run on: OIM host
    curl -s http://<repo-server-ip>:8080/slurm_custom/repodata/repomd.xml | head

Configure in Omnia

After hosting the repository, add the URL to local_repo_config.yml:

File: /opt/omnia/input/project_default/local_repo_config.yml
user_repo_url_x86_64:
  - { url: "http://<repo-server-ip>/slurm_custom/", gpgkey: "", name: "slurm_custom" }

For aarch64:

File: /opt/omnia/input/project_default/local_repo_config.yml
user_repo_url_aarch64:
  - { url: "http://<repo-server-ip>/slurm_custom_aarch64/", gpgkey: "", name: "slurm_custom" }

Important

The repository name must be slurm_custom to match the software_config.json entry.
