OPS245 Lab 1
!!!THIS LAB IS NOT READY YET!!!
In this lab we'll set up three new virtual machines to act as servers, and we'll use Debian for the Linux distribution.
To give you a better overview of the common Linux installation options available: the three servers will be installed using different methods.
You'll need two ISO files:
- A large DVD image which includes all the packages you're likely to install. Download the latest one from here.
- A much smaller "netinst" image. This contains just the most common defaults, and the rest is downloaded from the internet during installation. Download the latest from here (for example debian-11.6.0-amd64-netinst.iso).
server1
The relatively large DVD ISO file you'll use for installing server1 (that's the number 1, not the letter L) includes all the software that most people typically want installed. The rest of the software can be downloaded from the internet later. Putting all the available Debian packages on DVD images would require over 19 DVD disks, which very few people want therefore they're not even available for download.
It's a large file to download but the potential benefit is: you only need to download it once, and you can use it an unlimited number of times, therefore potentially saving much time and bandwidth. Since we're not installing a lot of software: the DVD download is not saving us any time or bandwidth, but hopefully it's not hard for you to imagine that you might install much more than the minimum selection of packages.
Create a new virtual machine in VirtualBox
- Name it server1
- Store it in the same location as your workstation (each VM will have its own folder)
- Pick Linux / Debian (64bit) for the Type and Version.
- Since we're not going to be installing a graphical user interface in this machine: it needs much less RAM, give it the default 1GB
- The graphical user interface also requires disk space, and since we're not installing one: allocate just 10GB for your new virtual disk.
