All these days…I’ve seen my fellow Oracle/MySQL DBAs working on NIX platforms, but I haven’t really got a chance to work Full time on these machines being a SQL Server DBA. Well, with Microsoft’s recent announcement(SQL coming to Linux), I’ve decided and committed to explore Linux in depth. “MySQL” and “Linux” are my go to technologies for my 2016 Road Map besides VMWare! I know that’s too much…but hey, there’s nothing wrong in setting goals for ourselves 🙂
So, why did I choose CentOS? Well, It’s simple….It’s free to download and a replica of RHEL(Red Hat Enterprise Linux). From my understanding, All the commands which run on CentOS should run in RHEL. Once we get the familiarity with these Operating Systems, working on any Linux/Unix machines should not be difficult. So, if you want to get started to Linux, my recommendation is to begin with CentOS.
Screenshot Tour of installing CentOS 7 on Oracle Virtual box:
Download CentOS 7.0(ISO) from their website(Just Bing it or google it).
Download Oracle VirtualBox and install on your machine. (I prefer installing it on a VM rather than creating a dual boot machine with Windows and Linux, YMMV).
In the above step, you can leave it to Minimal Install if you are sure that you absolutely don’t need a GUI. I selected KDE plasma for GUI…(We can load/start OS without GUI if needed, that’s probably what I would do after couple of days)
Once done, it asked me to reboot the VM. Now am ready 🙂
Note: I haven’t enabled networking and didn’t installed few things. well, if I see something wrong with my setup and if it isn’t working as expected….well, I can destroy my VM and build a new one as needed in just few minutes! That’s the beauty of a Virtual machine.
