Part -1:

Instructions: This lab provides you with experience in loading Apache in Fedora and Windows Server 2008. It also provides you with experience in installing Internet Information Services (IIS) Server in Windows Server 2008. This lab has three parts: installing Apache on Fedora, installing Apache in Windows Server 2008, and adding IIS to Windows Server 2008 as a role. Complete all three parts of this lab and attach this worksheet to your assignment when it is completed.

Part A, Installing Apache in Fedora.

Installing Apache in Fedora is a straight forward process that can be easily done in a few minutes. Since Apache can be installed anywhere in the Fedora file system, we'll do this first install in the lab1user's home directory.

Do the following steps to download the current version of Apache to Fedora.
1. Start your Fedora virtual machine and log into Fedora using the lab1user account that you created during the install process.
2. Open your browser and navigate to https://httpd.apache.org/download.cgi.
3. Locate the link for httpd-2.4.9.tar.gz and click on it. You will be prompted to open or save the file.
4. Verify that the Save File radio button is selected and click OK. The file will download to the /home/lab1user/Downloads directory on your Fedora virtual machine.
5. From the browser, right click on the [MD5] link to the right of the link for the file you just downloaded. Select the Save Link As... option on the menu that displays. You will be prompted to save the file as httpd-2.4.9.tar.gz.md5 in the Downloads folder.
6. Click Save. The MD5 hash file will be saved in the Downloads folder.
7. Minimize your browser, open a command prompt, and navigate to the /home/lab1user/Downloads folder.
8. Enter the following command: md5sum -c httpd-2.4.9.tar.gz.md5. If the file downloaded without errors, the md5sum command will return the following message: httpd-2.4.9.gz.md5: OK.
9. Enter the following command: tar -xzf httpd-2.4.9.tar.gz -C /home/lab1user . The tar command will create a directory called /home/lab1user/httpd-2.4.9 and extract the files to it.
10. If all of the steps completed successfully, you should be able to see the apache files in the /home/lab1user/httpd-2.4.9 directory.
Do the following steps to compile and install the current version of Apache in Fedora.
1. Verify that Apache is not already running by maximizing your browser, typing https://localhost/ in the Address text box, and pressing Enter. If you get a page not found error, Apache is not running. If you get a web page, Apache is running and you will need to shut it down using the procedures found in the Course Documents area of this course.
2. Maximize the command screen. At the command prompt type the following command and press Enter: su -. Remember to include the dash. You will be prompted for the root account password.
3. Type the password for the root account and press Enter. You will be logged in as root.
4. At the root command prompt, type the following command:

yum install gcc apr apr-devel apr-util apr-util-devel pcre pcre-devel

and press Enter. The yum installer will begin installing the compiler that will be used to compile Apache. After a short while, you will be prompted to answer if the installation is OK.
5. Type y each time you are prompted and press enter. After a short while, the installer will complete the installation of the specified modules and then return you to the command prompt.
6. Type exit and press Enter. This will log you out of root and return you to the user prompt.
7. At the user command prompt, change directory to /home/lab1user/httpd-2.4.9.
8. Type ./configure -prefix=/home/lab1user/apache/. This sets the installation directory for Apache.
9. Type make. After a few minutes, the make command will complete.
10. Type make install. After a few minutes the make install command will complete.
11. Type su - and press Enter. You will be prompted for the root account's password.
12. Type the password you gave the root account during installation. You will be presented with a root prompt (the pound sign).
13. Type /home/lab1user/apache/bin/apachectl start and press Enter. The Apache service will start.
14. Type exit and press Enter. You will return to the user prompt.
15. Change the permissions to read and execute for the group and others for the lab1user directory by typing chmod 755 /home/lab1user at the command prompt and pressing Enter.
16. Change the permissions to read and execute for the group and others for the apache directory by typing chmod 755 /home/lab1user/apache at the command prompt and pressing Enter.
17. Change the permissions to read and execute for the group and others for the htdocs directory by typing chmod 755 /home/lab1users/apache/htdocs at the command prompt and pressing Enter.
18. At the command prompt, type exit and press Enter. The command screen will close and you will return to your desktop.
19. Verify that Apache is running by maximizing your browser, typing https://localhost/ in the Address text box, and pressing Enter. If you get a web page, Apache is running.
20. Maximize the Oracle VirtualBox VM Manager and verify that the Apache Web page is visible in the Preview window.
21. Left click on the title bar to select it, press and hold the Alt key, and press the PrtScn key. Windows will create a screen shot of the VM Manager. Note: The screen shot should be of the VM Manager, not the virtual machine itself. Windows has difficulty making screen shots of virtual machines.
22. Paste the screen shot here:
23. Close the Fedora 14 virtual machine. When prompted, click the Save State radio button to save the current state of the machine.

Instructions: This assignment explains how to use active content in Apache Web servers. Please complete the following steps and contact your instructor if you experience problems with it. This is a graded lab assignment. Make sure you attach the completed lab worksheet to your assignment.

I. Configuring Apache for Server-Side Includes

1. Using vi, open your /etc/httpd/conf/httpd.conf file.

2. Search for your Options directive (Options Indexes FollowSymLinks) in the file. You can search for a string in vi by typing a forward slash and then the string your are looking for. To search, you must be in command mode. If you are in insert mode, the forward slash will be entered as text. To return to command mode from insert mode, press the Escape key.

3. When you find the Options directive, modify it by adding Includes to it. When you are done, the directive should look like this:
Options Indexes FollowSymLinks Includes

4. Search for the two lines shown below:
#AddType text/html .shtml
#AddOutputFilter INCLUDES .shtml

Remove the pound sign (#) that is in front of each line to uncomment it.

5. Go to the end of the file and add the following line:

XBitHack on

6. Search for the following line. If it exists, put a pound sign (#) in front of it to comment it out:

Include conf/extra/httpd-vhosts.conf

7. Save the file and exit vi.

8. At the command prompt, type apachectl restart and press Enter to restart Apache.

9. Using vi, create a file in the /var/www/html directory called ssi.html. Add the following html code to it

<html>
<head>
<title>SSI Page</title>
