About the directory structure

While writing this book, a couple of Unix-like operating systems were used, more specifically Mac OS X and Ubuntu. So, when referencing a directory path, the format adopted is /some/folder. If you are a Windows user, the equivalent path would be C:\some\folder.

The base folder used in the book is /opt/packt/. Inside it, we're going to add a few more folders to accommodate the necessary components. Here's the basic structure you have to create before moving on to the next section:

/opt/packt/
 |- domains
 |- etc
 |- install
 |- workspace

Of course, you don't need to follow the preceding definitions. If so, just remember to change the references accordingly, when mentioned.
