Building a Linux virtual server

Post date: June 9, 2005, 14:06 Category: Software Views: 2991 Comments
Tutorial quote: With the explosive growth of the Internet, the workload on servers providing Web, email, and media services has increased greatly. More and more sites are being challenged to keep up with the growing demands and are employing several techniques to avoid overloading their servers. Building a scalable server on a cluster of computers is one of the solutions that is being effectively put to use. With such a cluster, the increasing requests can be easily managed by simply adding one or more new servers to the existing cluster as required. In this article we will look at setting up one such scalable, network load-balancing server cluster using a virtual server via the Linux Virtual Server Project.

Building a Virtual Cluster with Xen

Post date: September 28, 2006, 04:09 Category: Emulation Views: 7510 Comments
Tutorial quote: It is a common practice to have development and test servers for each production server, so that you can experiment with changes without the fear of breaking anything important, but this is usually not feasible with clusters. So how do you try that new version of your favorite program before committing it to the production cluster? A cheap and convenient possibility is to build a virtual cluster.

Thanks to the Xen virtual machine monitor, you can create a number of virtual machines, all running simultaneously in your computer, install different operating systems in them, or just different configurations, and connect them via (virtual) network cards. Xen is a terrific tool for building virtual Beowulf clusters. It can prove useful when learning or teaching about clusters or for testing new features/software without the fear of causing major damage to an existing cluster.

Building a Linux Cluster, Part 3: How To Get Started

Post date: April 25, 2005, 14:04 Category: Network Views: 2619 Comments
Tutorial quote: In the previous two articles in this series, we examined some of the whys and whats of building Linux clusters. This article concludes our series by concentrating on the hows of cluster building. We've seen that a clustered approach to certain computing solutions can save lots of money in hardware and support costs. Now our job is to produce a method of building clusters that's repeatable and predictable—we don't want to give back our hard-won savings in project cost overruns.

Building A Linux Router

Post date: February 26, 2007, 07:02 Category: Miscellaneous Views: 8082 Comments
Tutorial quote: Building a reliable, full-featured broadband router can be very easy and cost-efficient. This article is about building one for routing a LAN to the Internet with NAT (Network Address Translation -- Linux users also call it as IP Masquerading) using an old computer and a Linux micro-distribution designed to have very low hardware requirements. We'll end up having a very simple and stable system, yet featuring e.g. iptables based stateful firewalling and remote administration.

Building A Virtual Server (VPS) With Debian 3.1 (Sarge) And OpenVZ

Post date: March 20, 2006, 20:03 Category: System Views: 3220 Comments
Tutorial quote: In this HowTo I will describe the steps to be taken to prepare a server for OpenVZ virtual machines on Debian 3.1 (Sarge) 32Bit Linux. With OpenVZ you can create multiple Virtual Private Servers (VPS) on the same hardware, similar to Xen and the Linux Vserver project. OpenVZ is the open-source branch of Virtuozzo, a commercial virtualization solution used by many providers that offer virtual servers. The OpenVZ kernal patch is licensed under the GPL license, and the user-level tools are under the QPL license.

Building a Linux supercomputer using SSH and PVM

Post date: April 11, 2006, 21:04 Category: Network Views: 3184 Comments
Tutorial quote: If you have a couple of old Linux boxes sitting around, then you've got the makings of a supercomputer. Dust them off, install Secure Shell (SSH) and Parallel Virtual Machine (PVM), and start your complex algorithms.

Linux virtual server on Debian Sarge

Post date: November 29, 2005, 21:11 Category: System Views: 3374 Comments
Tutorial quote: Linux-VServer allows you to create virtual private servers and security contexts which operate like a normal Linux server, but allow many independent servers to be run simultaneously in one box at full speed. All services, such as ssh, mail, Web, and databases, can be started on such a VPS, without modification, just like on any real server. Each virtual server has its own user account database and root password and doesn't interfere with other virtual servers.

Building the ultimate Linux-based music server

Post date: July 24, 2007, 05:07 Category: Miscellaneous Views: 8590 Comments
Tutorial quote: This article describes how to build your own silent, fast, eco-friendly Linux-based PC for use in a digital music listening system. The PC is based on a high-end Via mini-ITX board, passively cooled case with heatpipe technology, Debian Linux, and a little creative embedded elbow grease.
