5.2. Creating Leostream Infrastructure VMs (Broker and Gateway)

The Connection Broker and Leostream Gateway install on the latest 64-bit CentOS 7 or Red Hat Enterprise Linux 7. Each component requires a unique VM.


Neither the Connection Broker nor the Leostream Gateway can be deployed on CentOS 8, Red Hat Enterprise Linux version 8, or any other Linux distribution.

When creating a virtual machine for the Connection Broker installation, ensure that the VM has, at least, the following resources:

  • 4 vCPUs

  • 8.0 GB of RAM

  • At least 20 GB of hard drive space

  • One NIC, ideally with internet connectivity

At a minimum, create a virtual machine for your Leostream Gateway with the following resources.

  • 2 or more CPUs or vCPUs at 2.5GHz or higher

  • 4 GB of RAM, more if using the built-in Leostream HTML5 viewer.

  • 4 GB of swap space

  • 20 GB of free disk

To create virtual machines using the VM creation wizard. Go to Compute > Virtual Machines and click Create Virtual Machine. For complete instructions, see Creating virtual machines. The following figure shows an example creating a VM for the Connection Broker from your CentOS 7 image and using a large flavor.


When creating the VMs ensure that the Connection Broker VM has access to the Broker-Network and the Gateway VM has access to the Gateway-Network by attaching the network during the VM creation wizard. If you forget to do so, you can attach the network once the VM has been created.
