Introduction

The world's leading open source application platform

Red Hat Enterprise Linux (RHEL) is a Linux distribution produced by Red Hat and targeted toward the commercial market, including mainframes. Red Hat Enterprise Linux is released in server versions for x86, x86_64, Itanium, PowerPC and IBM System z, and desktop versions for x86 and x86_64. All of Red Hat's official support and training, and the Red Hat Certification Program center on the Red Hat Enterprise Linux platform The long-awaited Red Hat Enterprise Linux (RHEL) 6 delivers improvements including KVM and improved scalability. However, Xen is no longer supported. Red Hat Enterprise Linux (RHEL) is a commercial Linux OS that is designed for businesses that need full support and the highest amount of reliability possible for mission critical applications. Historically, RHEL has been a derivative of the Fedora Linux project with features and release cycles that meet the requirements of Red Hat's commercial customers. On one certified platform, Red Hat Enterprise Linux offers your choice of: (i) Applications - Thousands of certified ISV applications; (ii) Deployment - Including standalone or virtual servers, cloud computing, or software appliances; (iii) Hardware - Wide range of platforms from the world's leading hardware vendors. This gives IT departments’ unprecedented levels of operational flexibility. And it gives ISVs unprecedented market reach when delivering applications. Certify once, deploy anywhere. All while providing world-class performance, security, and stability. And unbeatable value. This is why today Red Hat is the platform of choice. Xen has been dropped and instead KVM is used. KVM (Kernel-based Virtual Machine) replaced Xen as the virtualization product of choice. KVM is a bare metal hypervisor that runs directly on x86 hardware instead of on top of an operating system. It was distributed in RHEL 5.4 in a package called Red Hat Enterprise Virtualization Hypervisor (RHEV-H). With a memory footprint of only 128MB, it can easily be started from flash or a network drive. Hands-on Labs In this Hands-on Labs module, you will learn how to install RHEL6 from DVD ISO. You’ll also learn how to perform post-installation configuration e.g., upgrade the system with new patches and bug fixes, configure static IP address from dynamic one, change the computer hostname, modify hosts file, perform ping test among others. You’ll also learn Webmin as part of your arsenal. In this Hands-on Lab assignment you’ll have an opportunity to install LAMP: Apache2 (httpd), MySQL server, PostgreSQL server PHP. This also include: FTP server, NFS server, JDK6, Tomcat7 and Ant. I’ll also show you how to install JBoss AS 6.0 and the bundled option JBoss + Portal Bundle. Other assignments include installing DNS server, DHCP
