Fedora 19 Installation (on Main Host - f19host)
- 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 Fedora19 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 19 distribution
- Investigate information during and after the Fedora 19 installation
- Perform an update after a recent installation
Required Materials (Bring to All Labs)
- Fedora 19 LIVE CD (not used in lab1)
- Fedora 19 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 19 Full Installation DVD into the CD/DVD drive. Note: do NOT use the Live CD - that will be used later in lab2...
- Wait until the Fedora DVD boots (could take a few moments).
- Note the time at the beginning of your installation.
- When the Fedora19 Installation DVD boots, it will prompt the user for the default language. Select the default language (English) in the next install screen, and click Continue.
- You will be brought to an installation summary screen.
- Verify that the Keyboard is set to English (English (US)).
- Verify that "Gnome Desktop" is the default software selection.
- Click on the Date & Time icon. Select for the city of Toronto (you can type, select, or click on the graphical region on the map). When finished, click on the Done button located in the top right-hand corner. This will return you to the installation summary screen.
Part 2: Partitioning
- In the installation summary screen, click the Installation Destination icon (under the Storage section).
- Verify that your hard disk is the default destination for install (i.e. check mark underneath hard disk icon). Click the Done button.
- An Installation Options dialog box should appear. Select "I want to review/modify my disk partitions before continuing" and make certain that the Partition Scheme is set to LVM. Click the Continue button.
- A Manual Partitioning screen should appear. This is the screen where you can customize your partitioning information.
- Ignore the "New Fedora 19 Installation" section. Instead, Click the "Fedora Linux 19 for X86_64" to expand the section. Delete each partition in that section by clicking on each partition (eg. /, /home. swap), and click the minus button "-" on the bottom left-hand-side to delete and verify that you want to delete those partitions.
- When all the partitions are removed, click on the plus sign on the bottom left-hand-side to create your partitions. On your hard drive you will need to create at least the following partitions. These may be primary partitions or logical drives. If you have more space than 160GB available - you can add the extra space in equal parts to /home and /var/lib/libvirt/images
- 50GB for / (i.e. "root")
- 500 MB for /boot
- 40GB 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
- Click the Done button, and click Accept Changes in the Summary of Changes dialog box to return to the installation summary screen.
- Click Begin Installation to proceed with the install. During the installation process, you will need to create a root password and at least one regular user account.
- When the installation process 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.
- 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).
- It is recommended to open a web-browser and authenticate into the Senenet system by entering your Seneca username and password. You should do this in future labs in order to be connected to the Internet
- 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.
Issue and record the commands used and the output generated in each of the following steps:
- Open a terminal by clicking the Activities menu, and typing in the search area: gnome-terminal. A terminal program icon should appear: click on the icon to open a shell terminal.
- 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).
- Enter the following command and record the number:
rpm -qal | wc -l
- What is the difference between the commands: rpm -qa and rpm -qal? (Refer to the online man pages for the rpm command for an answer).
- 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:
