Overview of this book

Linux can be configured as a networked workstation, a DNS server, a mail server, a firewall, a gateway router, and many other things. These are all part of administration tasks, hence network administration is one of the main tasks of Linux system administration. By knowing how to configure system network interfaces in a reliable and optimal manner, Linux administrators can deploy and configure several network services including file, web, mail, and servers while working in large enterprise environments. Starting with a simple Linux router that passes traffic between two private networks, you will see how to enable NAT on the router in order to allow Internet access from the network, and will also enable DHCP on the network to ease configuration of client systems. You will then move on to configuring your own DNS server on your local network using bind9 and tying it into your DHCP server to allow automatic configuration of local hostnames. You will then future enable your network by setting up IPv6 via tunnel providers. Moving on, we’ll configure Samba to centralize authentication for your network services; we will also configure Linux client to leverage it for authentication, and set up a RADIUS server that uses the directory server for authentication. Toward the end, you will have a network with a number of services running on it, and will implement monitoring in order to detect problems as they occur.

Introduction


One of the powerful things that Linux on servers allows you to do is to create scalable web applications with little to no software costs. We're going to discuss setting up web applications on Linux using Apache HTTPD and NGINX (pronounced Engine-X), securing those servers and look at some of the limitations for scaling.

Apache HTTPD, commonly referred to as just Apache, is the number one web server software in the world. As of November 2015, it is estimated to host roughly half of all websites live on the Internet. It was initially created as a set of patches to the NCSA HTTPD server in 1995. In fact, the name Apache was a play on the fact that it was a patchy server. These days Apache HTTPD is a very robust, flexible, and feature packed web server option.

NGINX is a newer offering, with the initial release having come out in October of 2004. While less feature filled than Apache, it can often handle a larger load while utilizing less memory than Apache does. It can also be used...
