The advantages are clear: you get a secure system without DRM restrictions that works even on old hardware, and the best thing is: all software comes free of charge.

phpvirtualbox is a web-based VirtualBox front-end written in PHP that allows you to access and control remote VirtualBox instances. It tries to resemble the VirtualBox GUI as much as possible to make work with it as easy as possible. It is a nice replacement for the VirtualBox GUI if you run VirtualBox on headless servers. This tutorial explains how to install phpvirtualbox on a CentOS 6.2 server to manage a locally installed, headless VirtualBox.

When you rent a dedicated server nowadays, almost all providers give you FTP backup space for your server on one of the provider's backup systems. This tutorial shows how you can use duplicity and duply to create encrypted backups on the provider's remote backup server over FTP. duply is a duplicity wrapper script that allows us to use duplicity without interaction (i.e., you do not have to type in any passwords).

This tutorial shows how to combine four single storage servers (running Ubuntu 12.04) to one large storage server (distributed storage) with GlusterFS. The client system (Ubuntu 12.04 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.

This guide explains how you can run virtual machines with VirtualBox 4.1 on a headless Ubuntu 12.04 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.

This tutorial shows how you can install an Apache2 webserver on a Fedora 17 server with PHP5 (through PHP-FPM) and MySQL support. PHP-FPM (FastCGI Process Manager) is an alternative PHP FastCGI implementation with some additional features useful for sites of any size, especially busier sites.

Cherokee is a very fast, flexible and easy to configure Web Server. It supports the widespread technologies nowadays: FastCGI, SCGI, PHP, CGI, TLS and SSL encrypted connections, virtual hosts, authentication, on the fly encoding, load balancing, Apache compatible log files, and much more. This tutorial shows how you can install Cherokee on an Ubuntu 12.04 server with PHP5 support (through FastCGI) and MySQL support.

LAMP is short for Linux, Apache, MySQL, PHP. This tutorial shows how you can install an Apache2 webserver on a Fedora 17 server with PHP5 support (mod_php) and MySQL support.

Nginx (pronounced "engine x") is a free, open-source, high-performance HTTP server. Nginx is known for its stability, rich feature set, simple configuration, and low resource consumption. This tutorial shows how you can install Nginx on a Fedora 17 server with PHP5 support (through PHP-FPM) and MySQL support.

This document describes how to install a Postfix mail server that is based on virtual users and domains, i.e. users and domains that are in a MySQL database. I'll also demonstrate the installation and configuration of Courier, so that Courier can authenticate against the same MySQL database Postfix uses. The resulting Postfix server is capable of SMTP-AUTH and TLS and quota. Passwords are stored in encrypted form in the database. In addition to that, this tutorial covers the installation of Amavisd, SpamAssassin and ClamAV so that emails will be scanned for spam and viruses. I will also show how to install SquirrelMail as a webmail interface so that users can read and send emails and change their passwords.

This tutorial shows how you can configure Compiz on an Ubuntu Linux 12.04 (Precise Pangolin) Unity desktop (the system must have a 3D-capable graphics card - I'm using an NVIDIA GeForce 8200 here). With Compiz you can use beautiful 3D effects like wobbly windows or a desktop cube on your desktop. Ubuntu (Unity 3D) must be selected as your desktop environment.

This tutorial shows how you can install and run Shopware Community Edition (version 3.5.6) on a Debian Squeeze or Ubuntu 12.04 system that has nginx installed instead of Apache (LEMP = Linux + nginx (pronounced "engine x") + MySQL + PHP). Shopware is a feature-rich ecommerce platform; I will use the Community Edition here which is free. nginx is a HTTP server that uses much less resources than Apache and delivers pages a lot of faster, especially static files.

Unlike virt-manager, virt-install is a command line tool that allows you to create KVM guests on a headless server. You may ask yourself: "But I can use vmbuilder to do this, why do I need virt-install?" The difference between virt-install and vmbuilder is that vmbuilder is for creating Ubuntu-based guests, whereas virt-install lets you install all kinds of operating systems (e.g. Linux, Windows, Solaris, FreeBSD, OpenBSD) and distributions in a guest, just like virt-manager. This article shows how you can use it on an Ubuntu 12.04 LTS KVM server.

The advantages are clear: you get a secure system without DRM restrictions that works even on old hardware, and the best thing is: all software comes free of charge.

This guide explains how you can install and use KVM for creating and running virtual machines on an Ubuntu 12.04 LTS 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.

This document describes how to install and set up ownCloud on CentOS 6.2 on an nginx web server and php-fpm with postgreSQL database as backend. For other distributions there might be minor changes as to the software prerequisites installation procedures. This guide will not only help install the product, but also understand why certain points are done the way they are done.

This tutorial shows how you can install Lighttpd on an Ubuntu 12.04 server with PHP5 support (through PHP-FPM) and MySQL support. PHP-FPM (FastCGI Process Manager) is an alternative PHP FastCGI implementation with some additional features useful for sites of any size, especially busier sites. I use PHP-FPM in this tutorial instead of Lighttpd's spawn-fcgi.

Please note that Ubuntu Studio 12.04 uses Xfce as the default desktop environment.

Backups are usually made in one of two ways - either file-based which means that single files are backed up, often via synchronization and on an external disk, or image-based which means that a whole partition is stuffed into an image file that can be restored on the partition, containing everything there was on it. This tutorial covers image-based backups using Partimage from a live desktop environment.
