Linux Clustering

Linux Clustering is the premier resource for system administrators wishing to implement clustering solutions on the many types of Linux systems. It guides Linux administrators through difficult tasks while offering helpful tips and tricks. Not only does it offer a comprehensive look at today's clustering technology, but it provides system administrators the tools needed to keep their servers up and running with the lowest effort. The first section helps the Linux administrator prepare the best way to keep multiple computers up and streamlined. The second part introduces the reader to the heart of clustering technology and provides step by step examples on how to install and maintain even the most difficult clusters. Also included in the appendices are hard to find unparalleled resources for system administrators. These are excellent resource of information. The Web site (www.newriders.com) contains examples of code that readers can freely cut and paste into their own programs, as well as links to clustering information and software.

Autorentext
About the AuthorAbout the Author Charles Bookman fell in love with the personal computer when he was 12. He would stay after school to teach himself programming on the Commodore Pet. His experiences with Linux started during the 2.0.30 days, when he took the work computer at his counseling job and converted it into something that nobody there had ever seen. After they fired him, he knew that he was on to something, and has been a Linux evangelist ever since. Charles' hobbies include being up to no good, using sarcasm, listening to music, being snobbish about art, playing bass and guitar, and painting and drawing when he finds the time. He'll kick your butt at table tennis, and is learning a great game of pool as well. Charles currently works at the University of the Pacific as a UNIX systems administrator, maintaining its high-performance cluster. He runs a design company, and consults in his spare time. © Copyright Pearson Education. All rights reserved.

Klappentext
Linux Clustering: Building and Maintaining Linux Clusters provides Linux users with information about building their own Linux cluster from the ground up. It gives best practices, helpful hints, and guidelines about building one server or hundreds of servers at a level that administrators at any experience level can understand. From installation of the air conditioning and power in the data center, to alternative file systems to the final production run, this book provides you with everything that you need to know. Linux Clustering: Building and Maintaining Linux Clusters walks you through the initial design and selection of the best possible types of clusters, as well as covering monitoring tools and providing for disaster recovery. Not only does this book provide information on parallel and Beowulf type clusters, Charles Bookman goes into depth on high availability clusters, load balancing, and provides advice for writing your own distributing applications as well. Incorporating best practices and cutting-edge approaches, Bookman provides step-by-step and tried-and-true methods of bringing up a Linux cluster to production level.

Zusammenfassung
