Lab Exercise 3.2: Installing Linux Products and Managing Processes

In this exercise, you will install the Mozilla web browser on your server. Then you will practice managing Linux processes. Complete the following steps:

CAUTION

This lab assumes you have Internet access from your Linux server.

  1. Boot your Linux server and authenticate as your student user with a password of novell. Change to your root user account entering sux – at a shell prompt.

  2. Your SUSE Linux distribution comes with an older version of Mozilla, which was installed when the system was installed. You need to use a newer version in order to access Novell's NNLS web-based management utilities. To do this, you need to complete these steps:

    1. Select Applications, Internet, WWW, Mozilla.

    2. In your Mozilla window, browse to http://www.mozilla.org.

    3. Download the latest version of Mozilla to /tmp. You must use version 1.5 or later.

    4. When the download is complete, close your browser window.

    5. Open a terminal session.

    6. Change to the root user account by entering su – and supplying a password of novell.

    7. Change to the /tmp directory by entering cd /tmp.

    8. At the shell prompt, enter ls. Notice that the file you downloaded from Mozilla.org is a tarball file. For example, if you downloaded Mozilla 1.6, you will see a file named mozilla-i686-pc-linux-gnu-1.6-installer.tar.gz.

    9. Extract the tarball by entering tar –zxvf ./mo; then press the Tab key. Notice that the rest of the filename is automatically completed for you. The tab-complete feature of Linux makes typing long filenames much easier.

    10. At the shell prompt, enter ls. You should now see a new directory named mozilla-installer where the files from the archive were extracted.

    11. Enter cd mozilla-installer.

    12. Start the installation script by entering ./mozilla-installer.

    13. At this point, you will be presented with a graphical installation wizard that varies depending on the version of Mozilla you've downloaded. Follow the prompts presented to complete a typical installation to the /usr/local/mozilla directory.

Create an icon on your Desktop for the new version of Mozilla by completing the following steps:

  1. Right-click anywhere on your Desktop.

  2. Select New Launcher.

  3. In the Name field, enter Mozilla.

  4. In the Generic Name field, enter Mozilla.

  5. In the Command field, enter /usr/local/mozilla/mozilla.

  6. Select the No Icon button.

  7. Select an icon of your choosing for the Mozilla browser icon.

  8. Click OK.

  9. Close any open browser windows; then test your new launcher by double-clicking the Mozilla icon on the Desktop.

  10. The Mozilla browser should be displayed as shown in Figure 3.31.

Figure 3.31Figure 3.31 Mozilla running on SUSE Linux.

Install the Pure-FTP service on your server by completing the following steps:

  1. Start YaST on your server by selecting Applications, SUSE Menu, System, YaST2.

  2. When prompted, supply your root user's password (novell).

NOTE

When you do this, you'll notice that YaST returns a password error but runs anyway. You can safely disregard the error message.

  1. Select Install or Remove Software.

  2. In the Filter drop-down list, select Package Groups.

  3. Select zzz All.

  4. In the top-right frame, scroll down to and select pure-ftpd.

  5. Click Accept.

  6. When prompted, insert UnitedLinux 1.0 CD #2 and then click OK.

  7. Wait while the package is installed.

  8. When the installation is complete, click Close.

Follow these steps to manage the pure-ftpd service on your server:

  1. Open a terminal session and change to your root user account by entering su – and supplying a password of novell.

  2. At the shell prompt, enter cd /etc/init.d.

  3. Enter ls. You should see a script for the pure-ftpd daemon, as shown in Figure 3.32.

  4. Figure 3.32Figure 3.32 The pure-ftpd script.

  5. Check to see the runlevels pure-ftpd is configured to automatically start at by entering chkconfig –l pure-ftpd at the shell prompt.

  6. You should see that pure-ftpd is not configured to automatically start at any runlevel. Start the pure-ftpd service by entering ./pure-ftpd start.

  7. Configure pure-ftpd to automatically start at runlevels 3 and 5 by entering chkconfig pure-ftpd 35.

  8. Verify this change by entering chkconfig –l pure-ftpd.

Now you can practice managing Linux processes by completing the following steps:

  1. At your shell prompt, enter top.

  2. Sort the display by CPU usage by entering P.

Which process is using the most CPU cycles on your system?

  1. Open a new terminal session.

  2. Change to the root user with the su – command.

  3. Kill the top process by entering killall top. Notice that the top process in the first terminal session is terminated, as shown in Figure 3.33.
