In Detail

CentOS is widely respected as a very powerful and flexible Linux distribution, and it can be used as a web server, file server, FTP server, domain server, or a multirole solution. It is designed to handle the more demanding needs of business applications such as network and system administration, database management, and web services. CentOS is self-sufficient and fast while working, with the added benefit of global acceptance as a large number of the world's web servers run on it.

This book not only concentrates on the basics, but also supplements your existing knowledge on subject areas that are important in the Enterprise market, such as directory services, security configuration management, and web-based architecture. By the end of this book, you will be able to manage an Enterprise Linux network focused on management-centralized configuration, user management, and filesystem enhancements by covering everything from the latest filesystem advances with BTRFS through to learning about the new web server on the block—Nginx.
