Redhat on Kenno's Open Note

Enable a Repo the Ansible Way

Sat, 24 Apr 2021 22:50:37 +1000

Recently I need to install a package called Lmod on a Red Hat 8 server. Lmod is available from RHEL 8 EPEL8 repository, however it has a dependency called lua-filesystem which is only available from codeready-builder repository. On my RHEL 8 server, the codeready-builder repository is not enabled by default.

Here is how I’ve got Lmod installed manually:

# subscription-manager repos --enable codeready-builder-for-rhel-8-x86_64-rpms
# dnf install Lmod

Looking at the above commands, I needed to enable the codeready-builder-for-rhel-8-x86_64-rpms first before installing Lmod. The thing is, I’m going to forget that Lmod requires lua-filesystem which is not available from the same repository as Lmod unless I write it down somewhere. Or better yet, let’s automate it with Ansible!

Last night I published 4 or 5 of blog posts related to the Foreman/Satellite server. Well, it wasn’t a coincidence, it was me cramming the last minute for the Red Hat Satellite 6 Administration exam today. It’s also known as EX403.

Needless to say, I didn’t know what was in the exam, and I can’t share what was in exam I had taken today. What I can share with you is that I passed EX403!

Passed Red Hat Virtualization Exam EX318

Wed, 09 Dec 2020 14:32:35 +1100

Another month, another Red Hat exam has been ticked off the list. This time, it’s about the Red Hat Virtualization, a technology based on oVirt.

The code name of the exam is EX318, and as rumours has it, it’s one of the easiest Red Hat exams; I can’t agree more. The exam’s duration is 3 hours; it’s a hand-on closed book exams. The exam is based on Red Hat Virtualization version 4.3.

Today I passed the Red Hat Identity Management exa, EX362, with the score of 233/300.

The material used to prepare for the exam is the RH362 online course, provided Red Hat. At first I wasn’t sure if I should use of the 5 exam credits (as part of one-year training subscription), but it turned out that IdM/FreeIPA is useful and fun to learn.

Here are some tips for this exam:

Ansible Automation Exam EX407

Sat, 15 Dec 2018 21:18:44 +1100

Last week I passed the Red Hat exam, Certificate of Expertise in Ansible Automation (EX407), and I just want to note down my experience of taking this exam.

The exam duration is 4 hours, and I was able to complete all the questions in 3 hours and 45 minutes. Was it because questions were difficult? No, on the contrary in my opinions questions aren’t very difficult, comparing to the Ansible learning material in D407. Speaking about learning material, to prepare for the EX407 exams, I went through 2 courses: D407R (recording) and D407VC (Video Classroom). Apart from that, I have also been using Ansible at work for quite awhile.

Becoming a Red Hat Certified Engineer

Thu, 13 Sep 2018 23:55:20 +0000

After spending almost 8 weeks preparation, I finally took the Red Hat Certified Engineer (RHCE) exam yesterday. I found the questions are not very difficult, however it’s very easy to make mistakes. The exam duration is 3.5 hours and I had about 15 minutes left when I completed the last question.

Having done the the Red Hat Certified System Administrator (RHCSA) before, I remember if you receive an email from Red Hat with an attachment, that implies that you pass the exam. Well, the grade came back within 2 hours after exam, and this time there was no attachment. Oh my!
