Serving CGI Scripts With Nginx On Debian Squeeze/Ubuntu 11.04

Post date: October 3, 2011, 06:10 Category: Miscellaneous Views: 5811 Comments
Tutorial quote: This tutorial shows how you can serve CGI scripts (Perl scripts) with nginx on Debian Squeeze/Ubuntu 11.04. While nginx itself does not serve CGI, there are several ways to work around this. I will outline three solutions: the first is to proxy requests for CGI scripts to Thttpd, a small web server that has CGI support, while the second and third solution are very similar - both use a CGI wrapper to serve CGI scripts.

Installing PowerDNS (With MySQL Backend) And Poweradmin On Debian Lenny

Post date: July 11, 2010, 22:07 Category: Installing Views: 4060 Comments
Tutorial quote: This article shows how you can install the PowerDNS nameserver (with MySQL backend) and the Poweradmin control panel for PowerDNS on a Debian Lenny system. PowerDNS is a high-performance, authoritative-only nameserver - in the setup described here it will read the DNS records from a MySQL database (similar to MyDNS), although other backends such as PostgreSQL are supported as well. Poweradmin is a web-based control panel for PowerDNS.

How To Limit CPU Usage Of A Process With cpulimit (Debian/Ubuntu)

Post date: September 14, 2009, 09:09 Category: Miscellaneous Views: 4155 Comments
Tutorial quote: This tutorial shows how you can limit the CPU usage of a process with the tool cpulimit on Debian/Ubuntu. cpulimit is a simple program that attempts to limit the CPU usage of a process (expressed in percentage, not in cpu time). This is useful to control batch jobs, when you don't want them to eat too much CPU. It does not act on the nice value or other scheduling priority stuff, but on the real CPU usage. Also, it is able to adapt itself to the overall system load, dynamically and quickly.

Virtualization With KVM On A Debian Lenny Server

Post date: March 17, 2009, 11:03 Category: Installing Views: 5280 Comments
Tutorial quote: This guide explains how you can install and use KVM for creating and running virtual machines on a Debian Lenny 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.

Installing Xen 3.0 upon Debian Unstable, with a custom Kernel

Post date: December 29, 2005, 07:12 Category: System Views: 4249 Comments
Tutorial quote: Recently we demonstrated the process of installing a binary release of Xen 3.0 on Sarge, since the packages on Debian Unstable are not yet available for Xen 3.0 we're now going to look at installing it via the packages provided by Ralph Passgang. This also includes building a custom Xen kernel from source.

The advantage to building the Xen kernel from source is that you can add, or remove, drivers - so the kernel is utterly customised for your system.

Xen Live Migration Of An LVM-Based Virtual Machine With iSCSI On Debian Lenny

Post date: April 30, 2009, 11:04 Category: Miscellaneous Views: 4867 Comments
Tutorial quote: This guide explains how you can do a live migration of an LVM-based virtual machine (domU) from one Xen host to the other. I will use iSCSI to provide shared storage for the virtual machines in this tutorial. Both Xen hosts and the iSCSI target are running on Debian Lenny in this article.

Little-known APT utilities for Debian desktop users

Post date: July 30, 2006, 18:07 Category: Desktop Views: 3327 Comments
Tutorial quote: The Advanced Packaging Tool (APT) is a distinguishing feature of Debian-based systems. APT was the first major alternative in GNU/Linux to boast automatic dependency resolution. Most GNU/Linux users know it through the apt-get command, a utility that calls on the lower-level dpkg command. However, other APT-based utilities remain largely unknown to desktop users. Some of these utilities offer a range of functionality far beyond those of the basic tools.

Installing A Web, Email, MySQL DB Cluster (Mirror) On Debian 5 With ISPConfig 3

Post date: August 11, 2010, 23:08 Category: Installing Views: 4389 Comments
Tutorial quote: This tutorial describes the installation of a clustered web, email, database and DNS server to be used for redundancy, high availability and load balancing on Debian 5 with the ISPConfig 3 control panel. GlusterFS will be used to mirror the data between the servers and ISPConfig for mirroring the configuration files. I will use a setup of two servers here for demonstration purposes but the setup can scale to a higher number of servers with only minor modifications in the GlusterFS configuration files.
