In this labsection, you will learn how to install access your '''CentOS Full Install DVD''' as Matrix Linux account by two different methods: :* From within a workstation within a virtual machine using the '''VMware Workstation''' application.Seneca College lab:* From your own computer within or outside Seneca College
===Part 1: Accessing your Matrix Account from a Seneca College Lab ===
Before you can install your CentOS Full Install DVD onto your Virtual Machine, you must first create a storage container which is a virtual machine that will provide a platform for you to install your CentOS operating system.x
:'''Perform the Following Steps:'''
# Although the images may be a little out of date (i.e. not exact), you can refer to this listing of installation screenshots for general reference:<br>[[http://matrix.senecac.on.ca/~murray.saul/ops235/ssd2/ installation screen-shots] ]<br>
# Power up the computer in your Seneca lab in '''Windows'''.
# If you haven't already downloaded the CentOS 7 Full Install DVD ISO, then download the following link for the CentOS 7 Full Install DVD image on your local computer: <br>https://mirror.senecacollege.ca/centos/7/isos/x86_64/CentOS-7-x86_64-DVD-1810.iso# Plug your SSD drive into your computer. Note the drive letter for that device.# Format your SSD to use exFAT, '''not NTFS'''. Open ''My Computer'', right-click on the SSD, and select ''Format...''. The dialog box should have the '''exFAT''' option selected, as the example to your right shows. Once selected, click ''Start''.# Create a folder called: '''Virtual Machines''' on your SSD device.# On your Seneca computer lab workstation, click the '''Windows Menu''' button and type '''VMware'''.# There are two VMware products: '''VMware Workstation Pro''' and ''VMware Player''.# Run the '''VMware Workstation Pro''' application (do '''<u>NOT</u>''' run VMware Player!).# <span style="background-color:yellow;">In your VMware Workstation application window, click the '''Edit''' menu, then select '''Preferences'''. Under the '''Default Location For Virtual Machines''', enter the pathname for the newly created folder in your SSD device and click '''OK'''</span>.# Click on the item labelled '''Create a New Virtual Machine'''.<br><br>'''NOTE:''' We will just be creating a "shell" for the VM to contain our CentOS 7 Linux operating system.<br>This will allow us to configure the VM properly so it will boot-up properly in our Seneca labs.<br><br># Select the '''Custom (advanced)''' for the Virtual Machine Configuration setting and click '''Next'''.# Click '''Next''' at the next screen to proceed.# Select the '''I will in<u>s</u>tall the operating system later''' option and click '''Next'''.# In the next screen, select '''Linux''' as the '''Guest Operating System''', and '''CentOS 7 64-bit''' for the OS ''version'' and click '''Next'''.# Enter '''c7host''' for the ''<u>V</u>irtual machine name'' and note the location where the image will be stored on your Windows machine and click '''Next'''.<br><br>'''NOTE:''' Since this "virtual machine" will be supporting other virtual machines (i.e. nested VMs), it is recommended to select a '''higher number or core processors''' (like 2 or 3).<br>You can always change this setting later on to maximize the performance of running the "nested" VMs on your Host VM.<br><br># Select <b>1 CPU, 4 cores</b> and click '''Next''' . # In the following screen, change the Memory from ''1GB'' to '''8GB''' (i.e. '''8192 MB''') and click '''Next'''.# Click '''Next''' to accept the default (i.e. '''NAT''') for the network type.# Click '''Next''' to accept the default (i.e. '''LSI Logic''') for the SCSI Controller type.# Click '''Next''' to accept the default (i.e. '''SCSI''' for the virtual disk type).# Click '''Next''' to accept ''Create New Virtual Disk''.# Change the Maximum Disk Size from ''20GB'' to '''238GB''' and click '''Next'''.# Accept the default Disk File name (i.e. c7host.vmdk) and click '''Next'''.# Quickly review your VM settings in the final setup wizard dialog box and click '''Finish'''.# You should now see a detailed screen for your '''c7host''' VM on the right-hand side.<br><br>'''ATTENTION: PRIOR to proceeding, you MUST perform the following step <u>BEFORE</u> starting your Host VM in order to allow your Host VM to run correctly!!!<br>Students that do not follow these procedures exactly will run in to problems when trying to perform lab2 !!! You have been warned!!!.'''<br><br># Make certain that your Host VM is <u>'''NOT'''</u> powered on before proceeding!# In the right-hand window (below "c7host"), and below ''"Power on this virtual machine"'', click the link called '''Edit virtual machine settings'''.# <span style="background-color:yellow">In this setup dialog box, click the '''options''' tab and then click the '''Advanced''' option at the bottom of the list. On the right-hand side, under ''Firmware Type'', '''select the radio button for UEFI'''. Then click on the '''Hardware''' tab, and then select the '''CD/DVD (IDE)''' device and select in the right-side select the radio button for the '''use ISO Image file'''. Click the '''Browse''' button and specify the path of your downloaded CentOS 7 Full install DVD (most likely file is contained in your Downloads folder). Click '''Processors''', and click the check-box to <u>enable</u> '''Virtual Intel VT-X/EPT or AMD-V/RVI'''. When finished, click on the '''OK''' button</span>.# You will return to your c7host VM. Click '''Power on this virtual machine''' icon near the top to boot your c7host VM to start your c7host VM, and proceed to Part 2.x
===Part 2: Install CentOS on Access your Newly-Created VM Matrix Account From your own computer within or outside Seneca College ===
The next step is to perform a custom installation for your CentOS 7 virtual machine using the CentOS 7 Full DVD. Upon creation of your c7host virtual machine, The VMware Workstation application will automatically simulate a "boot" to allow you to complete the installation process to create the CentOS 7 operating system on that virtual machine.x
:'''Perform the following steps:'''
# Select from the installation menu: '''Install CentOS 7'''.
# Next, you will be prompted for a language. In the first screen, select language '''English''' with subselection '''English-Canada''' and then click the '''Continue''' button on the bottom right-hand screen.
# The '''Install Summary''' should now appear. This screen allows the installer to customize their CentOS 7 system prior to installation.
