Install Slurm on the VM

Install Slurm on the Linux virtual machine and configure the VM per your site's environment. Follow the instructions in the Slurm Quick Start Administrator Guide.

The user name for logging into the virtual machine is determined by the SSH key that was provided during the creation of the virtual machine.

A startup script is provided during the creation of the cloud environment. This script (cloud-init script) is executed after a cloud node is deployed and is used to set up the system environment so that nodes deployed in the cloud can communicate with the workload manager. A service specifically designed for cloud instance initialization is cloud-init and is utilized by NavOps when booting cloud nodes, therefore it must be installed on the VM. For more information about installing cloud-init, refer to the Cloudinit Documentation.

  1. SSH into the VM using the public IP address of the VM: 
    ssh IPV4PublicIP
    where IPV4PublicIP is the public IP address of the virtual machine.

  2. Enter the command: 
    sudo -i
  3. Copy the Slurm installation package to the VM.
  4. Using the Slurm Quick Start Administration Guide, install and configure the system. Make the path same as the one on the Head Node. The scaling process uses a lot of data from the server, this make it easier to run the cloud-init and create the environment.
  5. Configure the VM for your site's environment such as mounting file systems, connecting it to the authentication service, installing any applications, etc.
  6. Check if cloud-init is installed. For example: 
    yum list installed | grep cloud
  7. If cloud-init is not present, install it. For example: 
    yum install cloud-init
  8. Submit a job and test to ensure it is working as expected.
