Foreword

When I go back in time to when I bought my very first technical book (about Perl 4

programming), I had no idea what it would mean to me. Of course, I had expected to

learn about Perl, but indirectly the book opened a whole new world to me. The book

introduced me to Unix and taught me valuable things about operating systems in general.

It taught me about filesystems and networking, about Perl modules and Perl developers,

and about open source and communities.

Not only did it help me to discover all these things, but it also made clear what I

didn’t know. And although the book didn’t go into detail about a lot of topics, the fact

that it gave me a framework, a place to put newfound information and relate it to what

I already knew, was more important than anything else in that book.

Over the years I realized that the book itself was not that special, except that it

allowed me to start doing things with little hassle, learn from them, and build on that.

And the book was excellent in building momentum, with me learning and doing in a

rapid whirlpool of instant joy and eagerness for more. And although I was far from being

a good Perl programmer when I finished the book, it gave me the confidence to explore

without the fear of breaking things.

When you apply the examples of this book, The Definitive Guide to CentOS, I hope

you will get the same satisfaction and build that same confidence to help others with

CentOS. By reading this book and trying the examples, you become a member of the

CentOS community—or, as we say, the C in CentOS. But what is so special about CentOS?

Why CentOS?

Well, if you look at the different Linux distributions that exist today, CentOS has a

unique appeal because it doesn’t try to consist of the latest and greatest open source soft-

ware (which is in itself a never-ending story); it focuses instead on being the most reliable

and secure environment that is resistant to change over a seven-year lifetime. And apart

from resisting change, about every 24 to 30 months a newer CentOS version pops up with

newer software that is again tested for stability and goes unchanged for another seven-

year time span. It is up to you to decide when to stay or move to another version at any

point in time.

Those design characteristics make CentOS (and its commercial twin, Red Hat Enter-

prise Linux) perfect for environments where you don’t want to inflict too much change,

like an enterprise data center, but the same applies to, say, your office computer or your

personal laptop. With CentOS you minimize the time to maintain the operating system

and included software for the longest period possible. And as a benefit, you can discuss
