RHCE and RHCSA tips and tricks

I did the RHCE exam some time ago, and still there are some tricks and advices I tell the people to bear in mind some of the things I used and that were also provided in the Red Hat Enterprise 8 Administration book: Don’t remember every step, it’s not effective, for example as I don’t recall syntax for BIND, I do remember package that has some files with examples and I use that one to check what I need to do Install mlocate and run updatedb as soon as you start, then you can use locate <file> to find out files in your system Use your preferred editor… it’s common to use vi or vim as it’s pretty standard, but if you’re used to another, make yourself comfortable in the system. As one instructor like to say: “Anyone with unlimited amount of time will be able to pass the exam”. RHCE is a performance-based exam, that means that you need to cover all the required goals within the exam duration, and in the end, the goals is to accomplish, not to do in the smarter way. For example, if you’re told to configure resolv.conf you can either use nmcli to modify the settings or you can pipe the results to it via echo nameserver 1.1.1.1 > /etc/resolv.conf, in the end, both will have the same effect, and of course, using nmcli will be smarter when you’re keeping multiple systems and using automation… but for the exam, the goal is to focus on the fastest path to master at it. You can find more tricks at Red Hat Enterprise 8 Administration Enjoy! (and if you do, you can Buy Me a Coffee ) ...

Lego Volkswagen T2

I’ve been building the Lego Volkswagen T2 🛒#ad and took some pics about the final result and the comparison with the T1. Feelings: The rear door (above the motor) dismantles itself just by looking at it, the mechanism is interesting as it uses some sticks that get inserted inside the support, but the frame holding it, specially in the upper side is really weak… The sliding door on the side is nice, and has a mechanism to ‘open it’ by pushing a small button in the lower part of the van The bed opens a bit better than on T1, which also was easy to get dismantled, same as the table that can be folded which is a lot nicer. The details on the fridge are really nice, and the one with the gas seems just to cover the spot The steering wheel is not just decorative.. as with recent Creator Expert series, it actually moves the front wheels. The roof, instead of being ‘pushed’ or ‘dropped’, has a sliding mechanism that holds it to the lower part, so in order to remove it, you need to open the rear door, and then slide it out. Interestingly it also has a spring that keeps the roof open. Enjoy! (and if you do, you can Buy Me a Coffee ) ...

Unsupported upgrade for RHEL-based distributions without reinstallation

Most systems, based on RHEL, were not able to upgrade without reinstallation, or best said, not supported. The new version, that was released at around 18 months later contained so many changes that it was hard to test the upgrades themselves until leapp was introduced. Check the lifecycle here: https://access.redhat.com/support/policy/updates/errata However, the biggest problem could be the incompatibility of packages or package formats… but as usually there were some middle layers it was possible to upgrade without reinstallation by performing some manual steps. ...
