{{Admon/important|Enabling Virtualization on your Home Computer|If you are going to try this lab on your home computer, there are a few things you need to be aware:<br><br><ul><li>'''RAM Size considerations:''' Your Seneca Lab Workstations have '''16GB''' of RAM. Your home computer should have a sufficient amount of RAM in order to function efficiently.<br><br></li><li>'''Enable Virtualization in home computer's BIOS:''' Most home computers do not have Virtualization enabled on their computer's BIOS. In your machines BIOS/UEFI: Enable the options VT-X(required) and VT-D(only if available)</li></ul>}}

The next step is to perform a custom installation for your Centos7 virtual machine using the Centos7 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 Centos7 operating system on that virtual machine.

# Select from the installation menu: '''Install Centos7'''.

#During the installation process, you will required to create a '''root password''' (for administration access) and create a '''regular user account'''. Click on '''Root Password''' and enter your root password. Think of an appropriate password and record that password somewhere in case you forget! An indicator will appear to show you how secure your password is. Retype your root password and click '''Done''' (you may have to click Done <u>twice</u> if your password is not considered to be a strong password).

#Refer to the Information box regarding how to access the admin account from the command line.

SELinux stands for '''Security-Enhanced Linux'''. It is a component that helps to better secure the system to protect against intrusion (hackers). SELinux is enabled upon the default install of CentOS. SELinux can be a good thing, if you take care of it and know how it works. For this course it is strongly recommended that you '''disable SELinux by default''' because we won't have the time to reconfigure it every time the labs make it necessary.

# Disabling SELinux is quite simple.

# Study the Linux commands and their purpose to note computer software information for your installed c7hostVM. You should take time to issue each of these commands to view the output, and record this chart in your lab1 logbook.<br><br>

If you have performed the lab correctly, then you will get a series of <b><code><span style="color:#66cc00;border:thin solid black;font-size:1.2em;">&nbsp;OK&nbsp;</span></code></b> messages and you can proceed with the SIGN-OFF for lab1. On the other hand, if there were errors, then a <b><code><span style="color:#ff0000;border:thin solid black;font-size:1.2em;">&nbsp;WARNING&nbsp;</span></code></b> message will appear with general suggestions that you will need to fix on your c7hostVM in order to have your OPS235 sign-off in this lab in order to proceed to the next lab.

# Make certain that your '''c7host''' VM is running, open the Bash Shell terminal and issue the command: <b><code><span style="color:#3366CC;font-size:1.2em;">su -</span></code></b> and enter root's password.<br><br>
