Description

For all the incredible progress that Linux has been making in the desktop arena, the biggest impact of Linux is in the server marketplace, where it has been competing with both Windows and UNIX products. For many years now, several vendors have been providing a professional maintenance and support contracts for Linux, and this facilitated a reliable deployment of Linux machines in high availability ‘mission critical’ enterprise installations.
This course will guide the delegates through the complete process of building a Linux server. We will start by installing a very basic, minimal system. As we progress through the course, we will continue building an effective server machine, by adding and configuring most commonly used server applications, tools and programs. Many third-party applications will be referred to. Some will be installed and discussed with fair amount of detail, some will be mentioned and given only a brief recognition.

The course platform will be a distribution best lending itself to the smallest initial footprint. However, the discussions, material and exercises address every major Linux strand, and wherever specific tool, technique or method is relevant, Red Hat and other distribution specifics will be pointed out.
This course, together with the Essentials of Linux Administration, and Advanced Linux Administration has been designed to meet objectives of the industry standard Linux certification from Linux Professional Institute, specifically playing part in preparation for LPIC-1 and LPIC-2 exams.

Target audience

All existing Linux administrators, analysts, or system architects responsible for building, deploying and maintaining servers based on a Linux operating system. Also, experienced UNIX or network administrators who need to port their skills to Linux.

Prerequisites

•Delegates should have previously attended the Advanced Linux Administration course (or have equivalent knowledge) and have several months-worth of practical experience of administering a Linux system
•Alternatively, they must be able to demonstrate a solid experience (typically several years) of any UNIX system administration

Skills

Delegates will learn how to:

•Install a minimal server
•Configure and use tools for direct and remote server connectivity
•Install and configure DHCP
•Install and configure DNS server
•Share files through SAMBA
•Build and use a local software repository (YUM and APT)
•Install and configure LDAP server and client
•Implement a selection of file integrity techniques and tools
•Understand and be able to apply backup tools and applications
•Understand the architecture and install a basic LAMP server system
•Make use of integral and third party server monitoring tools
•Understand the architecture and components of a mail server
•Build a fully automated server deployment infrastructure
