Learning to Manage Linux Server

Sorry for not updating the blog for few days.
While wandering through the web I came across 2 new things that I want to learn:
1. Building Facebook Apps
2. Managing Linux web server

I recently started to take Facebook seriously because as an internet marketer I need to be at all the places where people are. I made more than 700 friends in about 30 days without spamming. Most of the people are from my own field. If you too wanna join me click here.
Now as I look at Facebook from monetization perspective I see if I can build a decent Facebook app than I can make some bucks. I started reading Facebook developer guides and also borrowed few books:
1. Facebook Application Development
2. Essential Facebook Development
3. Building FAcebook Applications for dummies

I haven't read any of those yet so can't say much about them.
Few ideas are there in my mind but I will be doing some brain storming and mind mapping before actually putting up an application.

Second thing that I started is Learning to manage Linux server. You might have read in my other post that I own a VPS at Servint. Although my VPS is fully managed and I really like the kind of service Servint provides but I still like to do things on my own. Yes there is risk on ruining things but thats what makes it more enjoyable. I am using Cent OS on my VPS so I knew a little bit about doing things on this OS, but I have Ubuntu installed on my laptop so I thought of learning Ubuntu to make learning a bit quicker.
Here is what I learnt until now:

• Installing Linux (off course)
• Installing Apache server
• Installing PHP
• Installing MySQL
• Installing SQLite
• Installing Bind
• Installing Mailserver
• Installing memcache
• Installing Litespeed server
• Installing NginX server
• Configuring all that I have installed
• and ruining most of the things ;-)

Lets see where I reach from here..
