Virtualization With KVM On A Fedora 12 Server
==============================================

This guide explains how you can install and use KVM for creating and running virtual machines on a Fedora 12 server. I will show how to create image-based virtual machines and also virtual machines that use a logical volume (LVM). KVM is short for Kernel-based Virtual Machine and makes use of hardware virtualization, i.e., you need a CPU that supports hardware virtualization, e.g. Intel VT or AMD-V.

VBoxHeadless - Running Virtual Machines With VirtualBox 3.1.x On A Headless CentOS 5.4 Server
=============================================================================================

This guide explains how you can run virtual machines with Sun VirtualBox 3.1.x on a headless CentOS 5.4 server. Normally you use the VirtualBox GUI to manage your virtual machines, but a server does not have a desktop environment. Fortunately, VirtualBox comes with a tool called VBoxHeadless that allows you to connect to the virtual machines over a remote desktop connection, so there's no need for the VirtualBox GUI.

Distributed Storage Across Four Storage Nodes With GlusterFS On CentOS 5.4
==========================================================================

This tutorial shows how to combine four single storage servers (running CentOS 5.4) to one large storage server (distributed storage) with GlusterFS. The client system (CentOS 5.4 as well) will be able to access the storage as if it was a local filesystem. GlusterFS is a clustered file-system capable of scaling to several peta-bytes. It aggregates various storage bricks over Infiniband RDMA or TCP/IP interconnect into one large parallel network file system. Storage bricks can be made of any commodity hardware such as x86_64 servers with SATA-II RAID and Infiniband HBA.

Installing Lighttpd With PHP5 And MySQL On CentOS 5.2
=====================================================

Lighttpd is a webserver designed to be secure, fast, standards-compliant, and flexible while being optimized for speed-critical environments. This post shows how to install it with PHP5 and MySQL support on Centos 5.2.

Virtual Mail And Jabber Server (xmpp) With iRedMail And Ejabberd On Ubuntu 9.10
===============================================================================

iRedMail is a shell script that lets you quickly deploy a full-featured mail solution in less than 2 minutes. Since iRedMail 0.5, it supports CentOS 5.x, Debian 5.x, Ubuntu 8.04, 9.04 and 9.10 (both i386 and x86_64). iRedMail supports both OpenLDAP and MySQL as backends for storing virtual domains and users. This tutorial shows you how to integrate Ejabberd into iredmail's ldap backend on Ubuntu 9.10, passwords will be stored in ldap and you can change the password through webmail.

Mandriva 2010.0 Samba Standalone Server With tdbsam Backend
===========================================================

This tutorial explains the installation of a Samba fileserver on Mandriva 2010.0 and how to configure it to share files over the SMB protocol as well as how to add users. Samba is configured as a standalone server, not as a domain controller. In the resulting setup, every user has his own home directory accessible via the SMB protocol and all users have a shared directory with read-/write access.

Learning Spam With SpamAssassin And All Of Your ISPConfig Clients [ISPConfig 3]
===============================================================================

This is a quick way of learning spam from all of your ISPConfig clients by running a quick and simple command. Please note that this is for ISPConfig 3, not 2.

How To Easily Migrate A PostgreSQL Server With Minimal Downtime
===============================================================

PostgreSQL is a great database server, but when your dataset is rather large, migrating a server by using pg_dump can be a rather long process. In this tutorial we will discuss a way to migrate a entire server with as little downtime as possible. To achieve this, we will be using the PostgreSQL built in features for PITR (Point in time recovery).
