Initial creation of the VM

Instructions:

  1. Download the latest Centos 7 Minimal ISO from https://www.centos.org/download/
  2. Open VirtualBox and create a new Virtual Machine (VM) by clicking the New button.
  3. Give the VM a representative name, such as ‘AnsibleControlNode’. Change the type to ‘Linux’, and the Version to ‘Red Hat (64-bit). Click Next.
  4. Depending on the VM usage, update the value or accept the default ‘Memory size’ and click Next.
  5. Accept the default ‘Hard Disk’ and click Next.
  6. Accept the default ‘Hard disk file type’ and click Next.
  7. Set the ‘Storage on physical hard disk’ to an appropriate level for your use case - click Next.
  8. Depending on the VM usage, update the value or accept the default ‘File location and size’ and click Create.
  9. Right click on the new VM in VirtualBox. Select Settings > System > Motherboard. Change the pointing device to USB Tablet. Click OK
  10. Right click on the new VM in VirtualBox. Select Settings > Storage. Select the empty disk drive under the IDE Controller. Under Attributes, click the small CD image, then ‘Choose Virtual Optical Disk File’. Locate the CentOs 7 Minimal ISO. Click Open. Click OK.
  11. Double click on the new VM in VirtualBox to power it on.
  12. Select Install CentOs 7 using the cursor keys. Hit Return. After a short pause, you will be presented with a GUI to guide you through the installaton of CentOs.
  13. Choose your desired language settings and click Continue.
  14. Select Installation Destination, and accept the defaults by clicking Done.
  15. Begin the installation in the background by clicking ‘Begin Installation’
  16. You can now set the root users password by clicking on it. Enter the password twice and click Done.
  17. As we do not want to be using the root used by default, we will create another administrator account for our use. Click ‘User Creation’. Enter a Full name and User name. I suggest ‘ansible’ for both. Ensure the ‘Make this user administrator’ checkbox is checked. Enter the password twice and then click on Done.
  18. Wait for the installation to complete, and then click ‘Finish configuration’
  19. Click the Reboot button, and wait for the VM to restart.
  20. Login to the VM using the non-root account.
  21. To connect the VM to your host, we now need to make a change to the VMs network card. 
    sudo vi /etc/sysconfig/network-scripts/ifcfg-enp0s3
  22. Edit the ONBOOT line to equal ‘set ONBOOT=yes’. Save the file.
  23. Or sed -i ‘/ONBOOT/s/no/yes’/ /etc/sysconfig/network-scripts/ifcfg-enp0s3
  24. Restart the VM using ‘reboot’
