What you need for this book
The requirements of this book are relatively simple and begin with the need to download the CentOS operating system. The software is free, but you will need a computer that is capable of fulfilling the role of a server, some free installation media (blank CD-R/DVD-R or USB device), an Internet connection, some spare time, and a desire to have fun.
In saying that, many readers will be aware that you do not need a spare computer to take advantage of this book as the option of installing CentOS on virtualization software is always available. This approach is quite common and where the recipes contained within these pages remain applicable, you should be aware that the use of virtualization software is not considered by this book. For this reason, any requests for support regarding the use of this software should be directed towards the appropriate supplier.
