Provides the knowledge and skills needed to understand and improve the performance of Linux servers. It describes the collective practical experience of IBM Linux Technology Centre experts in Linux performance monitoring, evaluation and measurement, analysis, and tuning of Linux servers.

Updated to cover version 2.4.x of the Linux kernel, the second edition of Linux Device Drivers remains the best general-purpose, paper-bound guide for programmers wishing to make hardware devices work under the world's most popular open-source operating system. The authors take care to show how to write drivers that are portable--that is, that compile and run under all popular Linux platforms. That, along with the fact that they're careful to explain and illustrate concepts, makes this book very well-suited to any programmer familiar with C but not with the hardware-software interface. It's worth noting that the emphasis in the title is on "device drivers" as much as "Linux". This book will make sense to you if you've never written a driver for any platform before. It helps if you have some Linux or UNIX background, but even that is secondary as a prerequisite to C skill.

Apache is far and away the most widely used web server platform in the world. Both free and rock-solid, it runs more than half of the world's web sites, ranging from huge e-commerce operations to corporate intranets and smaller hobby sites, and it continues to maintain its popularity, drawing new users all the time. If you work with Apache on a regular basis, you have plenty of documentation on installing and configuring your server, but where do you go for help with the day-to-day stuff, like adding common modules or fine-tuning your activity logging? The Apache Cookbook is a collection of problems, solutions, and practical examples for webmasters, web administrators, programmers, and everyone else who works with Apache. For every problem addressed in the book, there's a worked-out solution or "recipe"--short, focused pieces of code that you can use immediately. But this book offers more than cut-and-paste code. You also get explanations of how and why the code works, so you can adapt the problem-solving techniques to similar situations. The recipes in the Apache Cookbook range from simple tasks, such installing the server on Red Hat Linux or Windows, to more complex tasks, such as setting up name-based virtual hosts or securing and managing your proxy server. The two hundred plus recipes in the book cover additional topics such as: Security Aliases, Redirecting, and Rewriting CGI Scripts, the suexec Wrapper, and other dynamic content techniques Error Handling SSL Performance The impressive collection of useful code in this book is a guaranteed timesaver for all Apache users, from novices to advanced practitioners. Instead of poking around mailing lists, online documentation, and other sources, you can rely on the Apache Cookbook for quick solutions to common problems, and then you can spend your time and energy where it matters most. pixel

With more than 67 per cent of web servers running Apache, it is by far the most widely used web server platform in the world. Apache has evolved into a powerful system that easily rivals other HTTP servers in terms of functionality, efficiency, and speed. Despite these impressive capabilities, though, Apache is only a beneficial tool if it's a secure one. To be sure, administrators installing and configuring Apache still need a sure-fire way to secure it--whether it's running a huge e-commerce operation, corporate intranet, or just a small hobby site. Our new guide, Apache Security, gives administrators and webmasters just what they crave--a comprehensive security source for Apache. Successfully combining Apache administration and web security topics, Apache Security speaks to nearly everyone in the field. What's more, it offers a concise introduction to the theory of securing Apache, as well as a broad perspective on server security in general. But this book isn't just about theory. The real strength of Apache Security lies in its wealth of interesting and practical advice, with many real-life examples and solutions. Administrators and programmers will learn how to: * install and configure Apache * prevent denial of service (DoS) and other attacks * securely share servers * control logging and monitoring * secure custom-written web applications * conduct a web security assessment * use mod_security and other security-related modules And that's just the tip of the iceberg, as mainstream Apache users will also gain valuable information on PHP and SSL/ TLS. Clearly, Apache Security is packed and to the point, with plenty of details for locking down this extremely popular and versatile web server.

MySQL is the world's most popular open source database. MySQL is designed for speed, power, and flexibility in mission-critical, heavy-use environments and modest applications as well. It's also surprisingly rich in features. If you're a database administrator or programmer you probably love the myriad of things MySQL can do, but sometimes wish there wasn't such a myriad of things to remember. With MySQL in a Nutshell by your keyboard, you can drill down into the full depth of MySQL's capabilities quickly and easily. MySQL in a Nutshell is the indispensable desktop reference to all MySQL functions. Programming language APIs for PHP, Perl, and C are covered, as well as all the popular MySQL utilities. This invaluable resource clearly documents the details that experienced users need to take full advantage of this powerful database management system. Better yet, this wealth of information is packed into the concise, comprehensive, and extraordinarily easy-to-use format for which the in a Nutshell guides are renowned. In addition to providing a thorough reference to MySQL statements and functions, the administrative utilities, and the most popular APIs, MySQL in a Nutshell includes several tutorial chapters to help newcomers get started. Moreover, each chapter covering an API begins with a brief tutorial so that, regardless of your level of experience in any given area, you will be able to understand and master unfamiliar territory. MySQL in a Nutshell distills all the vital MySQL details you need on a daily basis into one convenient, well-organized book. It will save you hundreds of hours of tedious research or trial and error and put the facts you need to truly tap MySQL's capabilities at your fingertips.

The unexpected pleasure of reading books about databases is that they are often written by authors with highly organised minds. Paul DuBois and his editors at New Riders have assembled MySQL with a clarity and lucidity that inspires confidence in the subject matter: a (nearly) freely-re-distributable SQL-interpreting database client-server primarily geared for UNIX systems but maintained for Windows platforms as well. What isn't "free" about MySQL (the application) is its server's commercial use; all clients and non-commercial server use are free. DuBois's tome isn't free either, but its list price is modest in light of its own and its namesake's value.

Web Database Applications shows Web developers how to build rich Web database applications using two leading open-source technologies, PHP and MySQL. The authors also assume use of the Apache Web server, which is by far the most common PHP scenario. Both PHP and MySQL are introduced from scratch, although this is a fast-paced book best suited to at least intermediate developers.

After a brief discussion of Web database applications, the authors offer a rapid tour of PHP essentials, including loops, expressions, functions and common mistakes. Next comes a quick-start guide to MySQL, focusing mainly on the SQL language itself. The following chapters tackle connecting to MySQL and other databases, implementing user-driven queries and enabling writing as well as reading data. There is a useful chapter on data validation, both on the client and the server and excellent coverage of another crucial subject: security and authentication. This looks at the fundamentals of HTTP authentication and examines security features in both Apache and PHP, identifying weaknesses and explaining pros and cons. The closing chapters form a detailed case study, an online wine store, with complete code available for download. It embraces user management, a shopping cart, searching, ordering and delivery, covering many key topics in the process. At the back of the book are appendices on a range of issues, including installation, Web protocols, database modelling and session management.
