Installing A Web, Email And MySQL Database Cluster (Mirror) On Debian 5.0 With ISPConfig 3

Installing A Web, Email And MySQL Database Cluster (Mirror) On Debian 5.0 With ISPConfig 3

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.

Anybody have a few millions lines of Apache Log files they can share?

Июнь 16th, 2010
Anybody have a few millions lines of Apache Log files they can share? I am working on a lab/demo on InfiniDB and need a few millions lines of an Apache HTTPD log file. I no longer run any large websites and would rather use real data over creating something. I will sanitize your URL so you will be anonymous, so www.YourCompanyHere.com will end up as www.abc123.com or something similar.

The demo/lab will show how to load data into the columnar InfiniDB storage engine and run some analytics against the data. Please let me know if you can help.

Disrupting IT with Open Source & Cloud

Июнь 2nd, 2010

A couple of weeks ago I gave a presentation at the Apache Lucene Eurocon in Prague. It was a good conference focused on Lucene/Solr open source search technology and sponsored by Lucid Imagination.  

I've posted the bulk of the presentation below.  (I omitted a couple of slides that were MySQL specific.) Even though it was a technical conference, I got positive feedback from the attendees and organizers that the information was useful in helping folks think about where to focus their efforts.  

The slides have been posted to Box.net and are shown using their new "embedded preview" feature which is pretty cool. You can also use the short URL www.tinyurl.com/box-disr

Thanks to the folks at Lucid Imagination as well as those who gave input and feedback on the presentation.

How To Set Up WebDAV With MySQL Authentication On Apache2 (Ubuntu 9.10)

How To Set Up WebDAV With MySQL Authentication On Apache2 (Ubuntu 9.10)

This guide explains how to set up WebDAV with MySQL authentication (using mod_auth_mysql) on Apache2 on an Ubuntu 9.10 server. WebDAV stands for Web-based Distributed Authoring and Versioning and is a set of extensions to the HTTP protocol that allow users to directly edit files on the Apache server so that they do not need to be downloaded/uploaded via FTP. Of course, WebDAV can also be used to upload and download files.

Reviewed: Managing Software Development with SVN and Trac

Март 18th, 2010

I’ve recently been migrating my wiki/documentation for Kontrollbase to Trac. For those that are not aware, Trac is a web-based documentation/wiki/Subversion tool that is used by countless number of software projects. Subversion, of course, is a software collaboration and code management repository that manages branches/tags/trunk files with revision control. It’s one of the most heavily used open-source code repositories available. Given that I use SVN (subversion) for all of my software applications and am now using Trac, the book “Managing Software Development with Trac and Subversion” by David J Murphy comes as a useful and great resource for integrating these two useful tools.

The book is not a thousand plus pages type of computer manual. It gets the important points out in a very readable and organized method without winding the user through overly extensive examples. What you get with this book is everything you need to know about combining SVN with Trac without the fluff of other manuals.

In regard to the application of this book, it fits several groups of users; managers that need to understand how their software development team is managing code – or wants to implement a more productive system for their software team, the software developers themselves that need to get up to speed on these most important of technologies, as well as up and coming technologists that want to learn about the code development and management process. Its well roundedness is one of the best features.

The content is broken up into several sections: content management basics, Trac and SVN basics, trac and svn setup and integration, documentation creation and management, code management, and then very useful appendixes for the actual install process of apache, SVN, and Trac. Each section has everything you need to get started and finished in quick order. The author is showing that the processes involved in code management do not have to be stressful or difficult to learn.

The author stresses several key ideas before getting into the meat of the content. These being “everything is a task”, “small steps are better”, “communication is key”, “content management is what software development requires for success.” Overall the two main division of labor is between task management and communication between team members.

Overall this is a very useful book on the subject of code management and documentation. I would recommend it to anyone looking to learn about the processes involved as well as anyone that wants a reference manual for growing their technology bookshelf.
