{{Admon/caution|THIS IS AN OLD VERSION OF THE LAB|'''This is an archived version. Do not use this in your OPS235 course.'''}} =Fedora 19 17 Installation (on Main Host - f19hostf17host)=
:* 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 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.
==Objectives==
# Perform a GNU/Linux installation using the Fedora 19 17 distribution# Investigate information during and after the Fedora 19 17 installation
# Perform an update after a recent installation
==Required Materials (Bring to All Labs)==
* Fedora 17 LIVE CD* Fedora 19 17 x86_64 Installation DVD (4.1 GB)* SATA Hard Disk (in removable disk tray - storage capacity at least 250 GB)
* USB Memory Stick
* Lab Logbook
 
(Note: Fedora 19 LIVE CD is not used in lab1)
==Prerequisites==
==Resources on the web==
Additional links to tutorials and HOWTOs:

==Investigation 1: How to Perform a Fedora DVD Install on Your Removable Hard Drive ==
=== Part 1: Beginning Installation 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 17 Installation DVD''' into the CD/DVD drive. '''Note: do <u>NOT</u> use the Live CD - that will be used later in lab2...'''
# Wait until the Fedora DVD boots (could take a few moments).
{{Admon/important|Booting from DVD/CD and External Drives Boot-up Issues (Fedora17) in Seneca's Computer labs|Please following If for some reason, the steps below to properly Fedora17 Installation DVD does not boot from your CD/DVD:
:* Restart the computer, and '''press the function key F10 to specify the device to boot''' (eg. DVD drive).
:* Choose the DVD drive from the list of devices avalable for boot.
:* You will need to perform this technique to ensure that Fedora boots from the hard drive (in future labs).
:* If you have tried this technique, and the Fedora Installation DVD does not boot, you may have to burn a new Fedora Installation DVD.  Note: Follow the same procedure when booting to your external hard disk in future lab sessions at Seneca's labs.|

<li value="5">Note the time at the beginning of your installation.</li>
<li>When the Fedora19 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 default languagelab, 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. </li> <li>Select the default language ('''English''') in the next install screen, and click '''ContinueNext'''.</li> <li>You will be brought to an Select the default '''keyboard layout''' and '''Basic Storage Devices''' in the following installation summary screenscreens.</li> <li>Verify that Set your hostname (name of the Keyboard is set computer) to <big>'''English (English (US))f17host'''</big> (one word, no space, all lowercase).</li> <li>Verify Set your time zone to '''Toronto'''.

=== Part 2: Partitioning ===
{{Admon/importanttip |Manual vs Automatic PartitioningYou're supposed to use this hard drive only for this course|By default, the Fedora19 installation DVD will want But if you really need to automatically select the partitions that will be created during the installation process. It is important to NOT select the default partitioning processuse it for two courses, since you will be required to make customized partitions such as '''/var/lib/libvirt/images''' and also assign customized sizes the professor for the partitions. Please carefully follow the instructions below other (probably windows) course will allow it - ask your professor for correct setuphelp with partitioning. Not carefully following the instructions below can result in having to redo the entire installation process!|}}

  ==Investigation 2: Obtaining Operating System InformationHow 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.
{{Admon/tipimportant|Using Superuser Privilege|Throughout this course, you may need to execute commands using the privileges of the the administrative user (username "root", also called the "superuser"). To switch from your account to the root account, type the command: <code>su</code>
After switching user notice and make note of the change in your shell prompt. Also note the difference in output for the <code>whoami</code> and <code>pwd</code> commands.
'''Whenever this is required, make a note of it, and determine why superuser privilege is required.'''

{{Admon/important|SELinux|SELinux stands for '''Security-Enhanced Linux'''. It is a component that helps to better secure the system to protect against intrusion (hackers). Usually, SELinux is enabled upon the default install of Fedora. SELinux can be a good thing, if you take care of it and are aware that it is enabled or disabled. It is recommended that you '''disable SELinux by default''' for this course, since you will be communicating with other virtual machines and can cause machines NOT to communicate.}}
 
# Disabling SELinux on Fedora is actually quite simple, just edit the file '''/etc/selinux/config''' and change the following line to look like this:
