Nginx HTTP Server + PHP5 (With fast-cgi And xcache) On Ubuntu Feisty Fawn

Post date: October 10, 2007, 10:10 Category: Installing Views: 4855 Comments
Tutorial quote: Nginx HTTP Server + PHP5 (With fast-cgi And xcache) On Ubuntu Feisty Fawn

This HowTo describes the implementation of Nginx with php5 support (through FastCGI). The fast-cgi process will be initiated via spawn-fcgi. Nginx is a great replacement of Apache with very low memory footprint and contrary to Lighttpd, does not suffer from memory leak over time. You can then use all the memory left to unleash the power of mysql for instance by increasing the default query cache.

Post date: May 16, 2007, 22:05 Category: Security Views: 4197 Comments
Tutorial quote: This article will guide you through the entire process of setting up a secure website using SSL and digital certificates. This guide assumes that you already have a fully functional (and configured) server running Apache, BIND, and OpenSSL. Just as a side note, this guide was written based on a Fedora Core 6 distribution, but should be the same for most other distros out there.

VBoxHeadless - Running Virtual Machines With VirtualBox 3.0 On A Headless Ubuntu 9.04 Server

Post date: July 19, 2009, 11:07 Category: Installing Views: 2607 Comments
Tutorial quote: This guide explains how you can run virtual machines with Sun VirtualBox 3.0 (released on June 30, 2009) on a headless Ubuntu 9.04 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.

Avoiding greedy webclients with mod_bwshare

Post date: November 8, 2006, 04:11 Category: Network Views: 3532 Comments
Tutorial quote: If you're running a popular website you'll most likely notice that some clients are less well-behaved than others. Greedy clients can do anything from make numerous requests, to attempting to spider your entire site. One simple way of preventing these clients from slowing down your server is with the mod_bwshare module for Apache2.

Unfortunately mod_bwshare is not yet packaged for Debian GNU/Linux however installing it from the source code is very straightforward.

Easy Automated Snapshot-Style Backups with Linux and Rsync

Post date: February 1, 2006, 00:02 Category: Software Views: 3662 Comments
Tutorial quote: This document describes a method for generating automatic rotating "snapshot"-style backups on a Unix-based system, with specific examples drawn from the author's GNU/Linux experience. Snapshot backups are a feature of some high-end industrial file servers; they create the illusion of multiple, full backups per day without the space or processing overhead. All of the snapshots are read-only, and are accessible directly by users as special system directories. It is often possible to store several hours, days, and even weeks' worth of snapshots with slightly more than 2x storage. This method, while not as space-efficient as some of the proprietary technologies (which, using special copy-on-write filesystems, can operate on slightly more than 1x storage), makes use of only standard file utilities and the common rsync program, which is installed by default on most Linux distributions. Properly configured, the method can also protect against hard disk failure, root compromises, or even back up a network of heterogeneous desktops automatically.
