1. Write a short, concise description, of what *you* think a System Administrator is.
2. Write a summary of the installation of VirtualBox and the Ubuntu Server. Include details of how easy or hard it was, how long it took and any problems that were encountered.
3. Submit a screen capture of the Ubuntu Server systems disks (don't worry if it scrolls off the screen). Details of how to do this can be found in the Chapter 8 reading. The command to run is sudo fdisk -l.
4. Submit a screen capture of each of the following:
· the systems Volume Groups
· the systems Logical Volumes
· the systems Physical Volumes
Details of how these can be generated are provided in the Chapter 8 reading. The commands to run are sudo vgdisplay, sudo lvdisplay and sudo pvdisplay.
5. Submit a screen capture of the systems disk free space. Details of how to do this can be found in the Chapter 8 reading. The command to use is df.
6. A good System Administrator documents everything they do so that they can go back and do it again if they need to, without having to research the process again.
Now that we have done an installation using the "Base Server Installation" document, create a list of things that are important to record when installing or updating software.
Include the following basic details: date, author, changes/updates made, plus those details you think are important. Discuss it on the course forum if you are not sure what to do.
7. Run levels, starting up and shutting down:
Review the readings for the week and also the "upstart_cookbook" reference provided in the Readings section above and answer the following questions related to our Ubuntu Server.
a) Briefly describe each of the run levels available on our system.
b) Briefly summarise the startup and shutdown process for our system i.e. what happens during startup and shutdown. [The "upstart_cookbook" will help in answering this question.]
* Submit all answers, screen captures etc. as a single Word document zipped up as week01.zip.
