<h2>Become a Linux Ninja with Command Line Kung Fu!</h2><br />Do you think you have to lock yourself in a basement reading cryptic man pages for months on end in order to have ninja like command line skills?<br /><br />In reality, if you had someone share their most powerful command line tips, tricks, and patterns you'd save yourself a lot of time and frustration. What if you could look over the shoulder of a good friend that just happened to be a command line guru? What if they not only showed you the commands they were using, but why they were using them and exactly how they worked? And what if that friend took the time to write all of it down so you can refer to it whenever you liked?<br /><br />Well, a friend did just that. <em>Command Line Kung Fu</em> is packed with dozens of tips and over 100 practical real-world examples. You won't find theoretical examples in this book. The examples demonstrate how to solve actual problems and accomplish worthwhile goals. <br /><br />The tactics are easy to find, too. Each chapter covers a specific topic and groups related tips and examples together. For example, if you need help extracting text from a file look in the "Text Processing and Manipulation" chapter. <br /><br />Also, a comprehensive index is included. If you want to find every example where a given command is used -- even if it's not the main subject of the tip -- look in the index. It will list every single place in the book where that command appears.<br /><br />Here is just some of what you will learn by reading <em>Command Line Kung Fu</em>:<br /><ul><br /><li>How to quickly and easily repeat commands in your shell history</li><br /><li>Shortcuts for grabbing specific words from your shell history to use in your current command</li><br /><li>How to save a copy of your command line session for later reference</li><br /><li>How to strip out blank lines and comments from files</li><br /><li>How to control colorized text when uses pipes and pagers</li><br /><li>Ways to transform text: from changing case to substituting characters and more</li><br /><li>How to extract specific blocks of text from files or streams of input</li><br /><li>A quick tip to fix common typos</li><br /><li>How to edit files over the network</li><br /><li>How to compare the differences between files on your local computer and a remote one</li><br /><li>How to create and use SSH tunnels</li><br /><li>Ways to verify what programs are listening on what ports</li><br /><li>How to kill all the processes for a given user with a single command<br /></li><li>Strategies for dealing with multi-hop SSH connections</li><br /><li>How to disconnect from a server in a way that will allow you to pick up where you left off</li><br /><li>How to automate software installs that require user input</li><br /><li>Shell scripting tips</li><br /><li>How to automatically keep repeating a command until it succeeds</li><br /><li>The right way to delete a file that is being written to</li><br /><li>How to surf the web from the command line... and more importantly how to download anything from the web and interact with HTTP APIs</li><br /><li>Ways to determine who and what is using the most disk space</li><br /><li>How to secure your web browser session when using an open wifi hotspot</li><br /><li>How to generate random passwords from the command line</li><br /><li>Two tips for easily creating backups</li><br /><li>Tips for handling tar archives</li><br /><li>How to replace a string in multiple files at once with just one command<br /></li><li>and much more...</li><br /></ul><br />What you learn in <em>Command Line Kung Fu</em> applies to any Linux distribution including Ubuntu, Debian, Linux Mint, RedHat, Fedora, OpenSUSE, Slackware, and more.<br /><br /><h2>Scroll up, click the "Buy Now With 1-Click" button to get your black belt in Linux Command Line Kung Fu.</h2>

<h2>How to Setup a Highly Available LAMP Stack Even If You've Never Done It before, Don't Know Where to Start, or Don't Want to Spend Weeks Researching How to Do It.</h2><br />This step-by-step guide teaches you everything you need to know in order to eliminate single points of failure for your Linux, Apache, MySQL, and PHP based web applications.<br /><br />Do you wish you could ensure your web site was up all the time and finally enjoy a peaceful night's sleep?<br /><br />Do you want to be able to scale without downtime and handle unexpected surges of traffic?<br /><br />Do you want a solution that just works without spending weeks testing various combinations of technologies and software?<br /><br />Do you want someone to lay it all out for you and walk you through an entire deployment?<br /><br />If so, you're in the right place...<br /><br /><h3>I understand, because I've been there.</h3><br />I know what it's like to be woken up in the middle of the night when a web server goes down. I don't know about you, but I'm fairly grumpy at 2:47 A.M. when something is broke and I'm the one that has to fix it.<br /><br />That's why I strive to eliminate single points of failure and ensure service availability. I would much rather plan for failure ahead of time than have to react to it. If you have a robust design that's easy to support you can repair any failures at your convenience instead of trying to cobble together a makeshift solution in the middle of the night.<br /><br />I've spent countless hours designing, testing, and implementing high availability solutions for a wide range of Linux based services during my career. I've put together a well designed, well tested solution for the LAMP (Linux, Apache, MySQL, PHP) stack that easily scales to support an increasing number of users all the while decreasing downtime. I've taken each possible single point of failure into account from the obvious ones to the less than obvious edge cases you'll need to cover in order to have a truly robust design.<br /><br /><h3>This architecture and design:</h3><br /><ul><br /><li>Works on physical servers. If you're running on bare metal, this design will work for you.</li><br /><li>Works in virtual environments such as VMWare, VirtualBox, Ovirt, Red Hat Enterprise Virtualization (RHEV), KVM, and Xen.</li><br /><li>Works in the cloud -- You'll learn about the important nuances for running in the cloud. This design works whether you're using Amazon Web Services (AWS), Rackspace Cloud, or another provider.</li><br /><li>Scales without downtime鈥? add more servers or resources without users even noticing.</li><br /><li>Works with custom written web sites and applications that run on the LAMP stack.</li><br /><li>Supports popular open source web applications such as WordPress, Drupal, Joomla, MediaWiki, phpBB, Redmine, SugarCRM, and more.</li><br /></ul><br /><br /><h3>This demonstrates everything step-by-step...</h3><br />This is not just a design, though. It's an entire book complete with lessons and demonstrations you can use on actual Linux servers. In the book I'll be performing the demonstrations on Ubuntu servers, but the concepts are the same no matter if you're using RedHat Enterprise Linux, CentOS, or another distribution. The only real difference is the couple of commands you'll use to perform some of the software installations. The design and configurations remain the same.<br /><br /><h2>Apply what you learn to other situations</h2><br />Even though this course is targeted directly at the LAMP stack (Linux, Apache, MySQL, PHP), the concepts and techniques presented can be reused in a variety of other situations. If you ever need a floating IP, the ability to add more storage to servers without downtime, to balance loads across multiple servers, or deploy a highly available database cluster, you can put what you learn in this course to good use.<br /><br />The only thing between you and web site that stays up all the time is this book.
