OPS335 Web Server Lab

Basic Apache (Web Server) Setup

This lab will show you how to set up the Apache Web server using a Fedora 16 installed PC. You will need at least two systems to do this lab. The first could be Fedora on your removable hard drive while the second could be a virtual machine.

Prerequisites

Your hard drive should have Fedora 16, 64 bit Live edition already installed.
You should have at least one VM installed: also Fedora 16, 64 bit Live edition.
Both your host and guest should have default firewalls enabled.
Both your host and guest should have SELinux enabled.
Both host and guest should have all software updated.

Ensure the clocks on both machines are set to the correct date and time.

Testing your network

• Start Firefox on your host and authenticate yourself on Sene2net with your LEARN account.
• Ensure you can surf the web on your host machine.
• Start Firefox on your guest.
• Ensure you can surf the web on your guest. NOTE: you should not have to authenticate yourself on the guest.

Install and test Apache

• Login to vm02 and install the following three packages, if they are not already installed, like this

 yum install httpd httpd-tools system-config-httpd

• Still on vm01 you can now start your web server with this command

systemctl start httpd.service

• Using Firefox on the host go to address "localhost". You should get the "Fedora Test Page" which indicates your web server is running. Do not continue until this step works.
• Now create your own test page named index.html and put it into directory /var/www/html/. Reload the Firefox "localhost" web page - you should see your own test page now.
• Try viewing this web page from f16 (the gateway/host). You'll need to enter the IP address of vm01 in your Firefox browser. By default this address should be something like 192.168.122.aaa. If this doesn't work you may have to add a rule to the firewall on vm01 to allow incoming connections on port 80.
• Edit the /etc/hosts file on each PC in your network and include the IP address and host name for both PCs. Now try accessing your web site by name in stead of IP number. Note: we're not using DNS so /etc/hosts file should work in its place.
• Now, as root on f16 (the gateway/host), try to forward incoming http connections to our server on vm01 (the guest). Use an iptables command something like this

iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 80 -j DNAT --to 192.168.122.aaa 

Note: aaa is the IP address of your guest VM

• To test this setup you'll need to ask a classmate on another PC to try to use Firefox to view your web page. S/he'll have to enter your external interface IP number (142.204.141.yyy) in Firefox's address window.
• Finally, as root on vm01, use the following command to view/adjust your web server parameters:

system-config-httpd

• Change your listen port to 8080 and restart your web server.
• Go back to f16 and redo your iptables command to forward port 80 connections to the new port 8080 on vm01.
• Verify that other students on other PCs can still view your web page. If this doesn't work you may have to add a rule to the firewall on vm01 to allow connections on port 8080.

Completing the Lab

Answer the following questions and and email them to your teacher in ASCII text format

1. Give the full path names of the Apache log files.
2. What directory is the default server root? Give the full path name.
3. What directory is the default document root? Give the full path name.
4. What is the default configuration file for the Apache web server on Fedora 16? Give the full path name.
5. What is the default maximum number of connections allowed on the server by default?
6. What user/group does Apache run under on Fedora 16?
7. What exact command did you use to allow requests to port 80 to be forwarded to 8080 on your VM?
8. What specific command (give full details) would you need to use on f16 to forward ssh connections to vm01?
9. What is the web site for Apache?
10. What is Apache's current version number? Note: this may be different from the version running on Fedora 16.
