OPS335 Lab 5

In this lab we will have a quick look at several separate technologies that are often used together with the Apache web server to install and run web applications.

Apache on its own does little more than serve text pages, images, and other static files. You can format those pages to look nice but they won't have any dynamic functionality - they will always look the same.

To add life to a website more than just the web server is needed. A popular acronym is LAMP. It stands for Linux, Apache, MySQL, and PHP (or Python). This week we will set up this stack to give us a website that does webmail (send and receive email in a web browser).

Linux

We'll need a new virtual machine. Because you probably forgot how to install one - go through the exercise again, and set up a vm4 from scratch. Only a minimal setup is needed. Configure it in the same way that you've configured the other three main VMs. This should be a quick exercise for you by now, including:

• The installation,
• Connecting to the correct network with a static IP (the address 192.168.X.5 should be available),
• Making sure you're using your internal DNS server,
• Configuring default rules for your iptables firewall.

As an interesting exercise: configure all your network settings (except the firewall) during the installation wizard.

Apache

Install Apache (the package name is httpd), start the service, make it start automatically, and allow access to it through the firewall (Apache serves HTTP traffic which goes over TCP port 80).

Now if you navigate to vm4.youruserid.org in a web browser in your host - you should see an Apache testing page.
