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.

I am always keen to create scripts to carry out tasks so that those tasks become repeatedly correct. Once the script is created and tested, we will have the knowledge and faith that it will run in the same way every time and we will not make mistakes or miss critical steps, either because it gets boring or we are working late on a Friday night and just want to go home. Scripting itself is just knowing the command line well and being able to use it at its best. This truth remains across all systems that you will work with.
