RHCSA Lab - Day 1

As part of my 2016 professional objectives i’ve got attaining a RCHSA high on the list, i’ve been meaning to get this done for the last few years but never got around to it due to the cost. Thankfully this year my manager has signed off on it, along with my Puppet Certified Professional, so I can’t grumble. The business is going through big drive of getting certificates for people in our managed service department and i’m being took along for the ride.

First task on the list is getting a RHEL7 system installed and ready to be twiddled with. RedHat offers a 30 day trial of Red Hat Enterprise Linux, so if you don’t want to use CentOS7 (which is more than acceptable as RHCSA doesn’t delve deep in the RedHat proprietary technologies) you can grab a recent DVD installer from their website without much hassle. To avoid the question of entitlement usage of the business’ account i’ve setup my own personal account, which will be useful when I need to apply my certificate somewhere.

As I won’t be using a physical machine for my base system i’ll be making use of my ESXi system to create the base VM, hopefully when it comes to creating the KVM guests it’ll actually work.

I’m working to the “RHCSA & RHCE Training and Exam Preparation Guide” from Asghar Ghori. Its recommended setup is a single host system with 40GB storage and 4GB of RAM, which should be more than enough for the lab exercises outlined in the book. A quick run through the standard Red Hat installer with some minor custom options and we’ve got a working system up and ready.

With that, i’ll call it a “day”. I’m not going to cover the entire RHCSA certification as i’m already experienced with working with RHEL on a day to day basis, i’ll be mostly revising the odd parts I usually don’t touch. ACLs, SELinux, KVM, and AutoFS… Joy.
