Hi,
If you are logged in as root, then you can run applications - add/remove software. Then wait for it to build the list.
Click on servers, then if you have selected the mysql database to be installed during the installation you should have a check mark next to it. If not, then check it and then you can click on the optional packages button below to see the other packages available in that category.
If you don't know which ones to select, then I suggest that you take a look at these sites.

Apart from the mysql database server, you will also need to select some packages in the web server category below.
By using this method it is assumed that your internet connection is working as the package manager will try to download and install them that way.
If you don't have a broadband or adsl connection, then you will probably want to load the software right from the dvd.
Use the dvd and select the packages using the file manager to install them.
