My Notes from Open Source System Management Conference 2012

May 132012

Even this year I was in Bolzano (Italy) for the annual conference organized by Wuerth-Phoenix on Monitoring with Open Source products.

I found the conference very interesting, with speakers from around the world that have described several open source products and best practices on monitoring but also on configuration and management tools. A big surprise for me has been the strong push for alternatives softwares to Nagios for monitoring in particular Shinken and Icinga have received many praise.

But before I give some more details about the presentations a few words about the company that has hosted about 400 people in their, free of charge, event, Wuerth-Phoenix manufactures and markets an appliance called NetEye, within there are many Open source products including:

Nagios Core, with many preinstalled plugins, Cacti, ocsinventory, GLPI, NfSen, Nedi, and DocuWiki the highest level version has also OTRS, all these software are integrated with some web management interface developed by Wuerth-Phoenix itself. Continue reading »

We all know and love Linux and its distributions. Operating Systems that are lightweight, fast, highly customizable, free, advanced … These are just some of the thousands of qualities that our OS Linux have! But as we are also humble users and Linux users … not cocky, we recognize the limits of our sweet penguin, there is a cons we have to remember that this operating system gives to us! Perhaps this is the only … A penalty that surely does not affect all, me for first ! On our beloved Linux Box, in fact, is really difficult to find games with appealing graphics. Maybe you can find some games, but not one of the highest successful video games like GTA, NFS and so on …

At least so far…

Please write a short story about Zorin OS, or maybe just Linux in general.

Why do you use Linux? How did you come to the Linux world? What do you like here? What are you doing to promote Linux? Any of these, or maybe your own themes are good.

Nginx is an emerging Web server (it claims to power around 12% of the website) and is known for its high performance, stability, rich feature set, simple configuration, and low resource consumption.

Personally I’m using it from 2010 and so far so good, no particular problems, it does perfectly his work and is frequently updated by the developers, I’m really happy of how is performing on my VPS and in this time I’ve learnt some small tricks and tips that perhaps could save you some time in the future.

How to put Varnish in front of your Webserver without doing any change.

Varnish is an open source “web accelerator” which you can use to speed up your website.

It can cache certain static elements, such as images or javascript but you can also use it for other purposes such as Load balancing or some additional security, in general most of the people want to try it and test their website to see if it’s really so amazing (IMO yes, but test it yourself).

The traditional guides will tell you to move your webserver to another port, perhaps 81,8080 or just bind to localhost, configure Varnish to listen to port 80 and use the web server as backend, the server where Varnish will forward requests not found in his cache.

This is the “normal” configuration and it works fine, but sometimes you just want to make a quick Test or perhaps you are using a Control Panel, such as Cpanel, Kloxo or ISPConfig and in my experience change the standard listening ports of Apache is not a decision to be taken lightly with these tools.

So in a VPS (with Kloxo) I’ve used a different approach: iptables.
