All three nodes will have the same version. I'm going to leave the default location as it is. Select the location of your Virtual Machine on your host computer.Later on, I will name other worker nodes as 'cl-node-01' and 'cl-node-02'. This is the master node so, I am going name is as 'cl-master'. For the simplicity, I will keep the VM configuration same for all of the nodes i.e 2 CPUs, 2 GB RAM and 8 GB Hard Disk. Click OK and then OK again to save the preferences.“Supports DHCP” is checked by default.Name your NAT Network to something meaningful.Right Click on newly added NAT Network and edit the settings.Open VirtualBox and click on File ⇒ Preferences ⇒ Network.You can download putty from here.įirst of all let's create a small network for our cluster as we want to ensure all Virtual Machines created in that cluster are able to talk to each other. Putty to establish session with server from host computer.There may a slight variation of commands for Centos/Red Hat or other Operating Systems. I will be using 'ubuntu-18.04.3-live-server-amd64'. ISO image of any Linux based Operating System e.g.Official Installation Guide can be useful in case you need help. You've verified that your computer supports Virtualization and have already installed VirtualBox.This article assumes you have a Windows 10 Laptop or Desktop with 8 gig RAM and about 40 GB Hard Disk space available for your Linux Virtual Machines. Host machine is able to establish shell connection with virtual machines.Virtual machines are able to access internet to download patches or updates.

Virtual machines have their own network to communicate with each other.I thought I will note down the steps and share with the community for beginners while I am working on creating this cluster. Well, there is lot of material available in bits and pieces but I couldn't find anything serving my purpose. I thought it would be straight forward and I will be able to find instruction on Google quite easy. Of course, I didn't have three physical boxes available at home along with required networking cables etc. I wanted to create three nodes cluster for some R&D.
