VBoxHeadless - Running Virtual Machines With VirtualBox 4.1 On A Headless Ubuntu 12.04 Server

VBoxHeadless - Running Virtual Machines With VirtualBox 4.1 On A Headless Ubuntu 12.04 Server

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.

Distributed Replicated Storage Across Four Storage Nodes With GlusterFS 3.2.x On Ubuntu 12.04

Distributed Replicated Storage Across Four Storage Nodes With GlusterFS 3.2.x On Ubuntu 12.04

This tutorial shows how to combine four single storage servers (running Ubuntu 12.04) to a distributed replicated storage with GlusterFS. Nodes 1 and 2 (replication1) as well as 3 and 4 (replication2) will mirror each other, and replication1 and replication2 will be combined to one larger storage server (distribution). Basically, this is RAID10 over network. If you lose one server from replication1 and one from replication2, the distributed volume continues to work. The client system (Ubuntu 12.04 as well) will be able to access the storage as if it was a local filesystem.

Streaming Your Desktop With Audio And Webcam Overlay In A Browser Using ffmpeg, crtmpserver And Flowplayer

Streaming Your Desktop With Audio And Webcam Overlay In A Browser Using ffmpeg, crtmpserver And Flowplayer

This tutorial is based on Ubuntu Lucid, but will work on later releases as well with small changes. I will show how I stream my desktop with audio from pulse and webcam from video4linux2. I will also show how to configure crtmpserver and flowplayer so you can watch the live stream from a web browser. In this scenario I use separate host for the tools. Flowplayer is installed on a server running Apache, crtmp server is on a separate server and ffmpeg is installed on the streaming desktop.

High-Availability Storage With GlusterFS 3.2.x On Ubuntu 12.04 - Automatic File Replication Across Two Storage Servers

High-Availability Storage With GlusterFS 3.2.x On Ubuntu 12.04 - Automatic File Replication (Mirror) Across Two Storage Servers

This tutorial shows how to set up a high-availability storage with two storage servers (Ubuntu 12.04) that use GlusterFS. Each storage server will be a mirror of the other storage server, and files will be replicated automatically across both storage servers. 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.

Install Compiz On The Unity Desktop On Ubuntu 12.04 (Precise Pangolin)

Install Compiz On The Unity Desktop On Ubuntu 12.04 (Precise Pangolin)

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.

Running Shopware Community Edition (Version 3.5.6) On Nginx (LEMP) On Debian Squeeze/Ubuntu 12.04

Running Shopware Community Edition (Version 3.5.6) On Nginx (LEMP) On Debian Squeeze/Ubuntu 12.04

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.

Using PHP5-FPM With Apache2 On Ubuntu 12.04 LTS

Using PHP5-FPM With Apache2 On Ubuntu 12.04 LTS

This tutorial shows how you can install an Apache2 webserver on an Ubuntu 12.04 LTS 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.

Installing KVM Guests With virt-install On Ubuntu 12.04 LTS Server

Installing KVM Guests With virt-install On Ubuntu 12.04 LTS Server

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.
