If you're an experienced system administrator looking to acquire Linux skills,
or a seasoned Linux user facing a new challenge, Linux System Administration
offers practical knowledge for managing a complete range of Linux systems and
servers. The book summarizes the steps you need to build everything from standalone
SOHO hubs, web servers, and LAN servers to load-balanced clusters and servers
consolidated through virtualization. Along the way, you'll learn about all of
the tools you need to set up and maintain these working environments.
Linux is now a standard corporate platform with users numbering in the hundreds
of millions, and there is a definite shortage of talented administrators. Linux
System Administration is ideal as an introduction to Linux for Unix veterans,
MCSEs, and mainframe administrators, and as an advanced (and refresher) guide
for existing Linux administrators who will want to jump into the middle of the
book. Inside, you'll learn how to:
- Set up a stand-alone Linux server
- Install, configure, maintain, and troubleshoot a DNS server using BIND
- Build an Internet server to manage sites, perform email and file transfers,
and more
- Set up an email service for a small-to-medium-sized site, complete with
authentication
- Install and configure Apache, PHP, and MySQL on a web server built from
scratch
- Combine computers into a load-balanced Apache web server cluster based on
the free Linux Virtual Server
- Set up local network services from distributed file systems to DHCP services,
gateway services, print services, user management and more
- Use Linux virtualization with Xen or VMWare to run multiple kernels on one
piece of hardware; manage each kernel's access to processor time, devices,
and memory
- Create shell scripts and adapt them for your own needs
- Back up and restore data with rsync, tar, cdrecord, Amanda, and
MySQL tools
Linux System Administration is not only knowledgeable and practical,
but convenient. The ingredients for this book had been scattered throughout
mailing lists, forums, and discussion groups, as well as books, periodicals,
and the experiences of colleagues. Everything is now in one handy guide. In
the course of their research, the authors also solved many problems whose solutions
were completely undocumented. They now pass their lessons on to you.
