Have you always wondered how the Internet works and where do websites truly reside? Have you given a thought to the actual computer where the complete website for Facebook is stored and what all goes into the making of that server? This book will answer all your questions. Most of the websites that you see on the Internet today are hosted on a web server. A web server is just like the computer you have at home, with the exception that it is way more powerful. Just like you have a disk drive and RAM on your personal computer, there are multiple disks and RAMs on a web server. These disks have partitions created on them, just like your personal computer. At home, you may have you and your brother who use the computer, which means there are two users. A web server is a system where there are multiple users logged in at the same time and doing their work in parallel. Almost all the web servers in the world run on an operating system known as Linux. Consider a shopping website such as Amazon, which has users in the count of millions visiting it every minute. Now, this website is hosted on a Linux web server, and if the server were to shut down suddenly, it would leave these million users irritated, and it would eventually mean a loss in millions of dollars for the company. To make sure such a Linux web server goes through minimum or no downtime at all, there are people known as system administrators who are employed to ensure that the server is up all the time. They do various tasks on the server in the background while you are happily shopping in the foreground. This book will help you gain insightful knowledge on the tasks that system administrators perform on a Linux system to maintain it and to ensure that it never encounters any downtime.
