=OPS635 Pre-Lab: Host installation and virtual network setup=
==Overview==
In this lab you will configure the host with basic services and a virtual network that you will build on
for the rest of the course.
===Pre-Requisites===
None
This will start with a brand-new installation of Centos 7 on your drive. You may not re-use an
installation from previous semesters.
===Materials===
*One Solid State Drive (SSD), minimum capacity 240GB, in a USB3 Enclosure.
*One installation medium. Either a DVD or USB flash drive configured as an installation disc.
==Investigation 1: Host Installation==
Install Centos 7 Directly on your drive following the guidelines below.
*Networking Should be on.
*Set the hostname of the machine to be host.<domainname>.ops. Check blackboard for your assigned domain name.
*Set the timezone to Americas/Toronto
*Select Server with GUI as the installation type.
*The partition setup will be similar to what you had in previous OPS courses.
◦ Delete any old partitions on the drive.
◦ Provide a separate mount point for /var/lib/libvirt/images with at least 100GB.
*Set a good root password. No, not ‘P@ssw0rd’.
*Create a non-privileged user account using your MySeneca ID.
◦ If your MySeneca ID is long enough that typing it would be irritating to do on a regular
basis you may use an alternate name, but you must clear it with me first.
===On First Boot===
Make sure your machine meets the following conditions:
* Your NIC is set to automatically turn on when the machine does.
* Add a virtual interface to your existing one. Give it the static address 172.16.[x].1, where x is the network number on blackboard.
* SELinux is set to enforcing.
* The machine must be fully updated.
* You may use either iptables or firewalld as your firewall.
* Install libvirt and virt-manager. Set the virtualization service to start automatically when the machine boots.
* Reboot your machine
==Investigation 2: Basic Service Installation==
Configure the postfix service on your host to send and receive email for your domain.
*Install bind and configure your host as the master DNS server for your domain.
◦ It must provide forward and reverse lookups of the machines in your domain.
◦ As the course goes on, you will add entries to your zone for the machines you create.
◦ Create an MX record to direct all mail sent to users @<yourdomain>.ops to your host.
◦ It must allow machines in your virtual network to access the outside world (e.g. to get updates).
*Ensure both services start automatically when the machine boots, and allow the traffic for both through your firewall.
==Investigation 3: Virtual Network & Machine Installation==
*Remove the default virtual network.
*Create a new virtual network called opsnet.
◦ Address: 192.168.1[x].0/24, where x is the network number on blackboard. E.g. if your network number is 29, your opsnet network will be 192.168.129.0/24.
* Disable DHCP, and allow forwarding to any physical device using NAT.
*Install a new vm using the same Centos 7 release as the host machine.
◦ You may wish to provide the VM access to more than 1 CPU and 1 GiB of RAM so it installs and updates faster.
* During the installation process:
Set the hostname to blank.<yourdomain>.ops, using the same domain name as the host machine.
Provide your machine with a static address of your choice, using the host’s address for the primary DNS server and the gateway.
Set the timezone to Americas/Toronto.
Use a minimal installation (no GUI).
Set your root password, and create a non-privileged user account using your MySeneca ID.
* If your MySeneca ID is long enough that typing it would be irritating to do on a regular basis you may use an alternate name, but you must clear it with me first.
◦ Once the machine is installed, ensure it is fully updated.
*Shut down your VM, make sure the resource settings are reduced back to 1 CPU and 1 GiB of RAM.
*When you need a new VM, clone this one.
==Submission==
It is not necessary to submit this lab. If you wish to confirm that it has been completed
correctly, you may ask me to review it in class.
