Build Base VM

VirtualBox VM Settings

Create a VM with two network interfaces:

1. Host Only Network 
2. NAT

Base Memory:

• 2048 MB

Issue the following commands on your vm. The master node will require 2 cores and 2GB memory.

Update apt-get

> sudo su > apt-get update

Install openssh

HD Size

• 10 GB

Audio

• Disabled

Install Ubuntu or Centos and enable/install openssh if available.> apt-get install openssh-server

Enable both network interfaces

If you are installing Ubuntu server it will enable a primary network interface.

For VirtualBox VMs we are using 2 network interfaces:

• a NAT network used for accessing the internet (primary)a host only network for accessing the host from our machine without having to setup port forwarding. (primary)
• a NAT network used for accessing the internet

>ifconfig -a

Add the missing interface to your interfaces config file and reboot

...

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).


source /etc/network/interfaces.d/*


# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto enp0s8enp0s3
iface enp0s8enp0s3 inet dhcp

auto enp0s3enp0s8
iface enp0s3enp0s8 inet dhcp

> reboot

Login and get IP address:

Update apt-get

> sudo su > apt-get update

Install openssh

> apt-get install openssh-server

Now you can ssh into the virtual machine on the host-only network from your host
