Fedora 17 Installation (on Main Host - f17host)
- In this lab, you are going to install the Fedora (GNU/Linux Distribution) to your removable hard disk from your burned DVD.
- Although this will be a simple install, this Fedora Operating System will be a platform for other Virtual Machine Fedora installations (in future labs). Therefore, it is very important that you take the time to carefully read and perform ALL steps, and take time to check your work.
- After performing the Fedora17 DVD installation, you will collect baseline information about your Fedora GNU/Linux system, and perform some post installation configuration to prepare your system for the remainder of the labs.
- Perform a GNU/Linux installation using the Fedora 17 distribution
- Investigate information during and after the Fedora 17 installation
- Perform an update after a recent installation
Required Materials (Bring to All Labs)
- Fedora 17 LIVE CD
- Fedora 17 x86_64 Installation DVD
- SATA Hard Disk (in removable disk tray)
- USB Memory Stick
- Lab Logbook
- None (First Lab)
Linux Command Online Reference
Each Link below displays online manpages for each command (via http://linuxmanpages.com):
Normally you would read man pages on the machine you're working on using the man command, for example man rpm will show you the manual page for the rpm command.

Performing Lab 1
Investigation 1: How to Perform a Fedora DVD Install on Your Removable Hard Drive
Part 1: Simple Things
- Insert your removable SATA hard disk into the drive tray.
- Set your computer's drive selector switch to external (a.k.a position #4).
- Power up the computer and insert the Fedora 17 Installation DVD into the CD/DVD drive.
- Wait until the Fedora DVD boots (could take a few moments).
- Note the time at the beginning of your installation.
- When the Fedora17 Installation DVD boots, it will prompt the user to test the media (i.e. DVD) for integrity. Since time is limited for installation in the lab, select SKIP. On the other hand, if the install did not work, then you can test out the integrity of the DVD in the computer lab during your spare time.
- Select the default language (English) in the next install screen, and click Next.
- Select the default keyboard layout and Basic Storage Devices in the following installation screens.
- Set your hostname (name of the computer) to f17host (one word, no space, all lowercase).
- Set your time zone to Toronto. Note that the system (BIOS) clock is set to local time, not UTC.
- Root Password: enter a password of your own choosing. Pick one that is hard to guess to protect your system. (Recommendation: use the first letter and all the punctuation from a favorite phrase or song verse. For example, "To be or not to be, that is the question!" could become the password "Tbontb,titq!").
Part 2: Partitioning
- If you get a warning with something like "This device may contain data" - it's probably your new hard drive and you can safely use it.
- Select Create Custom Layout, we don't want to use the Fedora default setup now.
- On your drive you will need at least the following partitions. These may be primary partitions or logical drives. If you have more space than 250GB available - you can add the extra space in equal parts to /home and /var/lib/libvirt/images
- 20GB for / (i.e. "root")
- 30GB for /home
- 8GB for swap (Note: "swap" must be selected from the drop down menu)
- 100GB for /var/lib/libvirt/images
Part 3: Completing Installation
- Select in the next screen the Graphical Desktop applications, and in the additional repositories section (at the bottom) accept the default settings, then proceed. You may look at what's available if you choose "Customize now" but you don't need to customize the software installed at this point.
- Add in your lab logbook a brief description of the term "software repository" and what its major purpose serves (what you think it does). We will not add any existing repositories since we are not currently connected to the Internet. Therefore, we will customize the repositories later.
- Proceed with the installation. This may take some time. Record in your lab log-book the general steps in the installation process (displayed in the dialog box).
- When installation is complete, a screen will confirm completion, and ask the user to remove the DVD, and reboot the computer. Write in your lab log-book the time it took to perform this DVD Fedora install.
- Remove the Fedora Installation DVD, and click Reboot.
- When the system starts, set or accept the time and date default.
- Create a user account for yourself using the same user ID as your learn account, and create a suitable password.
- Normally, you would want to enable Network Time Protocol, but since we will be experimenting with the networking turned off in later labs, leave it disabled.
- Click on Do Not Send Hardware Profile.
- Finish the post-installation customization, wait for the login screen to appear, and then login to your computer account and your created (i.e. your name).
- Proceed to Investigation 2
Answer the Investigation 1 observations / questions in your lab log book.
Investigation 2: How many file packages and files are installed on the system?
For the rest of the tasks in this lab, you must login to your installed Fedora system using your Learn account, open a terminal and execute the following listed Linux commands to obtain information for your lab-logbook (lab1). If you get a Permission Denied message when trying to execute a command, then switch to the superuser account by running the command su - and type in your password for "root" (since you are the main administrator for your Fedora system). Once the intended command is executed, type "exit" to exit from the superuser account and return to your regular Learn account.
Navigate through your Graphical Fedora system, locate and run a terminal program (in order to issue Linux commands). Issue and record the commands used and the output generated in each of the following steps:
- The name of the installation log file is
/root/install.log-- It is an ASCII file (how can you be sure?) which can be viewed with the
- You can make use of this file to determine how many packages have been installed: complete the following command to count the number of packages that are labelled "Installing" in the installation log file:
grep ________________ /root/install.log | wc -l
- Using the
rpmcommand: you can also use the following commands to list all the installed packages, and the total number of packages installed:
rpm -q -a
rpm -q -a | wc -l
rpm -qa | wc -l
-qoption means query, and the
-aoption means all (in other words, query all installed software packages). Did you get the same number of packages from the above two methods?
- Some of the files on your system were installed with the software packages, and some were created by system activity (for example, by creating your Learn account and by logging in). If you know the package name (from the
install.log), you can list all the files that were installed from the package by using the following command:
rpm -q -l package_name
(where package_name represents the name of the application or package)
- This combines the
-q(query) option with the
-l(list filenames) option
- You can pipe the outupt through
wc -lto count the number of lines:
rpm -ql package_name| wc -l
- Using what you learned in steps 3, 4, and 7, get a count of the total number of files installed by all of the software packages on your system.
- To find out the name that you have assigned to your Linux system, enter the command:
- To find out the kernel version of your GNU/Linux workstation and the date it was created, enter the command:
- To find out all the system processes running on your GNU/Linux workstation, enter the command:
- To capture the list of all the system processes to a file called
ps.lst, enter the command:
ps -ef > ps.lst
- Copy the installation log file
/root/install.logand the file ps.lst to a USB memory key, or scp to your matrix account as a backup.
- View the section below to learn about and perform an update on your fresh Fedora install (you may have to find spare time to perform this install if you are running short on lab time). Do not proceed to Investigation 3 without performing an update.
Answer the Investigation 2 observations / questions in your lab log book.
Investigation 3: What is the network configuration?
- To check the network configuration settings obtained from the DHCP server, run the following commands, describing the output in your log book:
- nslookup (at the > prompt, enter the word "server" (do not type the quotes) and record the output. Type exit to leave nslookup).
- Find the following information in the output of the above commands:
- MAC address (physical or hardware address) of the ethernet network interface
- Subnet mask
- The IP address (logical address) assigned by the DHCP server
- The default route (gateway)
- The DNS nameserver
Answer the Investigation 3 observations / questions in your lab log book.
Investigation 4: SELinux
- Disabling SELinux on Fedora is actually quite simple, just edit the file /etc/selinux/config and change the following line to look like this:
