Exercise one: installing and securing MySQL using xampp
Step 1: Download and install XAMMP
Go to: http://www.apachefriends.org/en/xampp.html and click the link for your Operating
System.
Step 2: Once your download is complete, install the program, click on "Run"
Step 1: Accept the default settings.
A command will open and offer an initial installation prompt. Just hit the Enter key, and
accept the default settings. To simplify installation, just hit ENTER when prompted on
the command line. You can always change settings, by editing the configuration files
later.
Step 1: When your installation is complete, exit the command window by
typing x on the command line.
Step 1: Verifying and starting XAMMP
 Start the XAMPP Control Panel by clicking the short cut icon placed on the desk top.
 Start the Apache and MySQL components. You can also start the other components,
if you plan to use them.
 Verify the Apache install, by clicking on the Apache administrative link in the
Control Panel.
Verify the MySQL installation, by clicking on the MySQL administrative link in
the XAMPP Control Panel.
 If the verification steps are successful, XAMPP should be successfully installed on
your PC. Open a browser and enter "localhost" on your address bar. You will be
redirected to a page telling you that you've successfully installed xampp on your system
