#Recheck each of the created partitions, and make certain that the file-system type is set to ''ext4'' and the Device Type is set to ''Standard Partition''.
#Finally, add a swap partition (Mount Point: swap) for '''16 GB'''.

#A Summary of Changes screen will appear to show the partitioning operations that will be created. Click the '''Accept Changes''' and click '''Begin Installation''' in the Installation Summary screen to proceed with the installation.
#Start timing your host machine installation.
== Part 3: Completing the Installation ==
#When installation is complete, you will notice a message at the bottom of the screen stating: '''CentOS is now successfully installed and ready for you to use!'''
#Click the Reboot button. Your DVD will <u>briefly</u> open in the DVD drive bay. Make certain to remove this installation DVD so that Centos will boot from your hard drive.
#After the system reboots, a boot menu should briefly appear, then prompt the user to accept the License Information (what this is only a one-time occurrence).<br> In order to accept the purpose of accepting license agreement, issue the license?).#Click on following keystrokes:<br><br>'''1'''License Informationfollowed by ENTER (to select the license agreement prompt<br>''' and 2'''click that you agree followed by ENTER (to accept the license agreement)<br>''', click c'''Donefollowed by ENTER (to save the selection)<br>''' and then click c'''Finish Configuration'''.#Click Forward followed by ENTER (a second time to enable Kdump (what is continue booting into the purpose of this application?system).<br><br>

#Stop timing your installation and note the amount of time that your installation took to perform. Also take the time to fill in the c7host section of the installation comparison chart in your lab2 logbook.
#Open a web-browser and check to see if you can connect to the Internet.<br><br>
'''Answer Investigation 1 observations (all parts and questions) in your lab log book.'''
#Issue the command <b><code><span style="color:#3366CC;font-size:1.3em;">su </span></code></b> Issue the '''pwd''' and '''whoami''' commands to confirm your directory pathname. When finished logout of this account.
#Issue the command <b><code><span style="color:#3366CC;font-size:1.3em;">su - </span></code></b> Issue the '''pwd''' and '''whoami''' commands to confirm your directory pathname. What do you notice are the main differences between using '''su''' versus using '''su -''' ?
# An installation log file called <b><code><span style="color:#3366CC;font-size:1.2em;">/var/log/anaconda/anaconda.packaging.log</span></code></b> has been created to record the installation of your c7host machine. This file is an ASCII file which can be viewed with the <b><code><span style="color:#3366CC;font-size:1.2em;">more</span></code></b> command.
# 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:
:: <b><code><span style="color:#3366CC;font-size:1.2em;">grep -i installing packaging /var/log/anaconda/anaconda.packaging.log | wc -l'''</span></code></b>
<ol>
<li value="8">Issue that command displayed above. Does it work? If not, what account do you think you should be in? When you get the command working record this important information regarding commands and the admin account in your lab logbook.</li>
<ol>
<li value="10">The <code>'''-q'''</code> option means query, and the <code>'''-a'''</code> option means all (in other words, query all installed software packages). Did you get the same number of packages from the above two methods?</li>
<li>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 <code>installpackaging.log</code>), you can list all the files that were installed from the package by using the following command:</li>
</ol>
::<b><code><span style=" pointer-events:none;cursor:default;color:#3366CC;font-size:1.2em;">rpm -q -l gedit</span></code></b>
<li value="13">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.</li><li>How can you explain why this number is a lot larger than the total number of packages installed? Record your answer in your lab logbook.
