So as a bit of background, I am completely new to server admin.
I am a web designer, and generally know quite a bit about computers.
Until a few months ago, I had never used LINUX.
Now my desktop runs Mint, and I have moved to an Ubuntu Linux cloud server with Rackspace.
Essentially I have followed the following guide: http://www.symana.com/2010/12/setup-a-lamp-rackspace-cloud-server-running-ubuntu-10-10/
to get to a point where I have apache, phpmyadmin etc. set up.
Given that I have set up the server thus far, and I appreciate this is massively unknowledgable.. but everyone has to start somewhere.., but can I now just use the server like i used my shared hosting account at hostgator?
I have bought myself a book about Ubuntu server administration such that I can essentially learn as I go..
The reason I have moved to rackspace is because i like the easily expandable nature of their cloud server offering which is exactly what i need for some of my growing websites. At the same time, I dont want to be prone to massive security breaches, inefficient loads, bad database connections etc. on the basis of me not knowing much about server admin.
Could anyone advise on my situation, the suitability of my setup, and how I could perhaps improve my setup..?
