Preparing Virtual Machines for Skylar One

This section describes how to prepare virtual nodes or appliances before installing Skylar One (formerly SL1).

Use the following menu options to navigate the Skylar One user interface:

To view a pop-out list of menu options, click the menu icon ().
To view a page containing all of the menu options, click the Advanced menu icon ().

Virtual Machine Specifications

You can deploy Skylar One appliances on hypervisors from the following vendors:

VMware
Microsoft
Nutanix
Citrix
RedHat

For details about the hypervisor versions that are supported and the requirements and specifications for each Skylar One appliance, see the System Requirements page on the ScienceLogic Support Site.

You must have already allocated an IP address for each Skylar One appliance.

Ports for Virtual Appliances

See the section on ports to configure firewalls to allow traffic to and from the Skylar One appliances.

Build Nodes or Appliances in This Order

For ease of configuration, create nodes or appliances in this order:

Database Server
Administration Portal (if applicable)
Data Collectors
Message Collectors (if applicable)

Deploying a Node or Appliance on a VMware System

The following instructions describe how to configure a ScienceLogic virtual machine in VMWare. If you are looking for resources and support for VMWare, see the VMWare Marketplace: https://marketplace.cloud.vmware.com/.

To deploy a Skylar One node or appliance on a VMware system:

If you have not already done so, download the ISO file for Skylar One.
Using the vSphere client, connect to your VMware system as a user that has permissions to deploy a new virtual machine and use the Create New Virtual Machine wizard to create a new virtual machine.
In the Create New Virtual Machine wizard, select the configuration options that are appropriate for your environment and the current recommended specifications for the appliance type you are installing. For details about requirements and specifications, see the System Requirements page on the ScienceLogic Support Site.
On the Guest Operating System page, select Linux as the Guest Operating System, and then select Oracle Linux 8 (64-bit) in the Version drop-down list.
On the Network page, you must select VMXNET 3 in the Adapter field.
After completing the Create New Virtual Machine wizard, edit the settings for the virtual machine:
- Set the CPU and memory allocation to the values recommended on the System Requirements page on the ScienceLogic Support Site.
- Configure the CD/DVD drive to use the Skylar One ISO file.
Turn on the virtual machine and boot the VM from the Skylar One ISO file to begin installing the Skylar One Database Server.
Repeat these steps for each node or appliance in your Skylar One system.

Deploying a Node or Appliance on a Microsoft Hyper-V System

To deploy a Skylar One node or appliance on a Microsoft Hyper-V system:

If you have not already done so, download the ISO file for Skylar One.
Follow the instructions from Microsoft on creating a virtual machine in Hyper-V:

https://learn.microsoft.com/en-us/windows-server/virtualization/hyper-v/get-started/create-a-virtual-machine-in-hyper-v

When prompted to Specify a Generation for the VM, make one of the following selections:

Generation 1. Fully supports Oracle Linux and Skylar One.
Generation 2. To support Oracle Linux and Skylar One, you must disable the "secure boot" feature.

When prompted to Assign Memory and Connect Virtual Hard Disk, enter the hardware requirements as specified on the System Requirements page on the ScienceLogic Support Site.
On the Installation Options page, select Install an operating system later.
Complete the rest of the VM creation steps based on your specific needs. When you are done, click Finish.
If you selected a Generation 2 virtual machine in step 3, open a PowerShell session on the Hyper-V Manager host and execute the following PowerShell cmdlet to disable secure boot on the VM:

Set-VMFirmware "Test VM" -EnableSecureBoot Off

Follow the instructions from Microsoft to install the operating system (Oracle Linux 8 64 bit):

https://learn.microsoft.com/en-us/windows-server/virtualization/hyper-v/get-started/create-a-virtual-machine-in-hyper-v

In the Hyper-V Manager, right-click the VM and select Connect.
In the Virtual Machine Connection window, click Action and then select Start.
Repeat these steps for each node or appliance in your Skylar One system.
To install Skylar One on the Hyper-V virtual machine, see Installing Skylar One on Hardware Appliances and Virtual Appliances.

Deploying a Node or Appliance on a Nutanix AHV System

To deploy a Skylar One node or appliance on a Nutanix AHV virtual machine (VM):

If you have not already done so, download the ISO file for Skylar One.
Review Nutanix's best practices for deploying a n AHV VM: https://portal.nutanix.com/page/documents/solutions/details?targetId=BP-2029-AHV:vm-deployment.html

The AHV VM must be configured to operate on Oracle Linux 8.
Follow the instructions from Nutanix for creating an AHV VM through the Prism Element web console: https://portal.nutanix.com/page/documents/details?targetId=AHV-Admin-Guide-v6_5:wc-vm-create-acropolis-wc-t.html
When creating the VM, in the Compute Details section, set the CPU and memory configuration allocations to the values recommended on the System Requirements page on the ScienceLogic Support Site for your environment and the appliance type you are installing.
In the Disks section, configure the disks to use the Skylar One ISO file.
In the Network Adapters (NIC) section, add a network adapter that enables the VM to connect to the internet.
When you are finished creating the AHV VM, click Save. Nutanix begins creating the VM.
After the VM is created, select the VM from the Nutanix console, then power it on and boot the VM from the Skylar One ISO file to begin installing the Skylar One Database Server.
Repeat these steps for each node or appliance in your Skylar One system.
