Configuring Apache for Maximum Performance

Post date: February 12, 2006, 09:02 Category: Optimizing Views: 4648 Comments
Tutorial quote: Apache is an open-source HTTP server implementation. It is the most popular web server on the Internet; the December 2005 Web Server Survey conducted by Netcraft [1] shows that about 70% of the web sites on Internet are using Apache.

Apache server performance can be improved by adding additional hardware resources such as RAM, faster CPU, etc. But most of the time, the same result can be achieved by custom configuration of the server. This article looks into getting maximum performance out of Apache with the existing hardware resources, specifically on Linux systems. Of course, it is assumed that there is enough hardware resources - especially enough RAM that the server isn't swapping frequently. First two sections look into various Compile-Time and Run-Time configuration options. The Run-Time section assumes that Apache is compiled with prefork MPM. HTTP compression and caching is discussed next. Finally, using separate servers for serving static and dynamic contents is covered. Basic knowledge of compiling and configuring Apache and Linux are assumed.

How To Install VMware Server (Version 1.0.6) On An Ubuntu 8.04 Desktop

Post date: July 1, 2008, 10:07 Category: Installing Views: 3549 Comments
Tutorial quote: This tutorial provides step-by-step instructions on how to install VMware Server (version 1.0.6) on an Ubuntu 8.04 desktop system. With VMware Server you can create and run guest operating systems ("virtual machines") such as Linux, Windows, FreeBSD, etc. under a host operating system. This has the benefit that you can run multiple operating systems on the same hardware which saves a lot of money, and you can move virtual machines from one VMware Server to the next one (or to a system that has the VMware Player which is also free).

Enhance Your Mail Server With ASSP (Anti-Spam SMTP Proxy)

Post date: November 20, 2006, 19:11 Category: Software Views: 5269 Comments
Tutorial quote: ASSP stands for Anti-Spam SMTP Proxy. The ASSP server project is an Open Source platform-independent transparent SMTP proxy server that leverages numerous methodologies and technologies to both rigidly and adaptively identify spam. In short ASSP is the most kickass solution that is both free and works great. It reduced spam to an absolute minimum for me.

Apache - Serving up the Web

Post date: April 11, 2006, 22:04 Category: Network Views: 8734 Comments
Tutorial quote: The Apache Web Server is installed as part of the OpenBSD base system. This guide will help you configure the web server: (Apache 1.3.12 is released with OpenBSD 2.7 and 1.3.9 with OpenBSD 2.6)

To see how configurable the Apache/OpenBSD combination is we also look at allowing administrators to remotely review the server's status, we setup the system so we allow users on our system to have their own personal web-space. Of course, for the security counscious you probably want to turn some of these things off after you get things up and running.

LCD displays easy to use and easy to build

Post date: May 24, 2005, 18:05 Category: Hardware Views: 4134 Comments
Tutorial quote: This article presents now the "basic" model: LCD display and 2 buttons; simple and easy to build for everybody.

Lcdproc used to be at the very beginning a program to display some statistics (cpu load, uptime, time, ...) on an external LCD display. Over time it has however evolved into a much more generic solution. Today the lcdproc package contains LCDd, a generic server and LCD driver, plus many clients. One of those clients is still the actual executable called lcdproc which still shows server statistics however there are also others. This client server architecture has the big advantage that you do not need to write your client in a specific language. You just need to use the simple ascii protocol between client and server.

Server Monitoring With munin And monit On Debian Etch

Post date: May 13, 2007, 21:05 Category: System Views: 4580 Comments
Tutorial quote: In this article I will describe how you can monitor your Debian Etch server with munin and monit. munin produces nifty little graphics about nearly every aspect of your server (load average, memory usage, CPU usage, MySQL throughput, eth0 traffic, etc.) without much configuration, whereas monit checks the availability of services like Apache, MySQL, Postfix and takes the appropriate action such as a restart if it finds a service is not behaving as expected. The combination of the two gives you full monitoring: graphics that let you recognize current or upcoming problems (like "We need a bigger server soon, our load average is increasing rapidly."), and a watchdog that ensures the availability of the monitored services.

Creating a WebDAV server with apache2

Post date: May 26, 2005, 16:05 Category: Network Views: 5728 Comments
Tutorial quote: I needed a way to share information (both read and write) as easy as possible with friends in a quite restricted environment (firewall). In many cases, WebDAV which uses standard HTTP port 80 for comunication is a good solution for a file server application.
