Hey man thanks so much for all these RHCSA videos. Without a doubt they're going to be a huge reason why I'm going to pass my upcoming RHCSA exam. Very concise and easy to follow.
The "while condition" script did not work for me. However, when I used double parentheses instead of expr in both instances, it worked. For example "while test $(($NUMA + $NUMB)) -lt $NMAX instead of "while test $(expr $NUMA + $NUMB) -lt $NMAX"
i have been watching your videos for the past couple of days and they are just great especially that i am preparing for rhcsa , i know its been a while since you made this video i hope you plan to make more quality videos like this ,can you please make a video on how to setup an update server that acts as a single update point for all the servers on the network rather than updating each server seperately , i searched all over the internet and read many books but no luck , since i am coming from a microsoft background the concept of an update server in microsoft enviroment is nothing new , but in linux it seems something else . thank you again for the top quality videos your way of explaining things is far and beyond of what we are used to and keep up the good work ,you deserve the title of instructor of the year .
Hi...Do we need create a exclusive user to work with containers? And does it need to have root privileges (add it to wheel grp). Also it is mentioned in the RHCSA doc that " Podman is a stateless utility and requires a full login session. Podman must be used with an SSH session and cannot be used in a sudo or an su shell"...Please clarify.
Hi....The rd.break issue still seems to be there and i could not complete the questions on node2. I raised a ticket on this issue cis i think its not fare to loose the chance to pass the examm in the first attempt itself. Thank you so much for uploading the video and your explanation is awesome. Let me know if you are providing training on RH.
Yup! That’s an awesome and interesting point you have brought up. I would like to add on that bash is often set up to automatically disable its non-POSIX and bash-specific features when it is invoked with the name `sh` (typically achieved using a link to the executable) so it can effectively behave like the simpler Unix shell for compatibility. Thanks, and take care!
@@beanologi here is some trivia for you. Did you know the kernel when the system boots still calls /sbin/init. They have made /sbin/init a link to systemd
Writing your own ansible.cfg from memory is wild, I always just initialize a disabled one and enable the settings I need to overwrite. In this video it also would have been nice to show the usage of the ansible-config command to show settings that have been explicitly changed. Overall great video though.
That part was referring to the ctrl+alt+delete key sequence which typically triggers a restart on many Linux text-console environments when performed on the physical keyboard. There are also ACPI hardware events that can also tell the OS to reboot and those are often easily exposed in virtual machine tooling to send a power state message to VM to politely power off or reboot it. You would use these means of initiating reboots when you can’t log in and run a command like `reboot` in cases where you don’t know the user password. Hope that helps answer your question.
Yup, this is why I failed! This is poorly documented! I even checked the product documentation they provided and lo and behold, it only mentioned *rd.break* I kept trying it over 10 times, and then gave up when it kept prompting me to enter the root password in maintenance mode.
Great video, I utilized the steps provided for generating systemd but it seems that the podman systemd generate command had been deprecated and quadlet is to be used now, It is possible to give an updated version on how to achieve the same results through quadlet maybe in the details section. However i do know if there is an updated video out already on using the quadlet to set up a systemd service
IMHO, the "systemd.debug_shell" kernel parameter is better, you end up with a root debug shell on tty9 and SELinux is still on, so you don't have to change the /etc/shadow context after changing the root password.
Configure disk compression is no longer on the RHCSA objectives for anyone watching. However, I'm sure the video will still allow you an understanding of how VDO works : )
Super easy to understand. I have been studying for RHCSA for about 3 months and completed Sander's book a couple days ago. After taking his practice exam, my weak points were NFS and containers (I skimmed the containers portion as his explanation was not very good). Thank you for making these videos! They were suggested to me by a guy on facebook.
Looks like that bug you mentioned regarding having no space between the user flag and username has been fixed. I was able to use ansible-inventory run -m stdout simple.yml -u admin -k and have the correct user specified.
What's up beano I set up all the servers , if I want to make it a replica of the exam environment how would I do that with the just two nodes. Would I use workstation and app server one or make a clone of workstation and use workstation one as node one and the clone as node? Thanks
Hi there, I cannot disclose many details about the exam environment. In general, with the disclosed exam objectives and Rhcsa documentation in mind, they do imply you will be configuring more than one machine which you show to understand just fine. Nonetheless, It doesn’t hurt to have more than 2 servers set up, as I have in my labs, as you can test more admin configurations simultaneously without resorting to many VM snapshots. In a realistic sysadmin environment, it isn’t uncommon for sysadmins to use a GUI terminal and ssh client like SuperPUTTY or gnome-terminal and ssh to administer a real system in the field. The rhcsa tries to be realistic in that aspect. Another general tip is to use the minimal available installation profile for RHEL so you know how to fetch any DNF packages that are not guaranteed to be installed out of the box. Lastly, You may want to watch Red Hat’s remote exams tutorial which can provide some context about the environment with a RH approved resource for exam candidates to refer to. Thanks
Hey man, thx for the helpful content ♥ Do you happen to know if the current RHCSA exam is running on RHEL 9.0 or 9.3? I'm asking because I've managed to recover root password on RHEL 9.3 both with good old rd.break, and with the method you showed in this video.
RHEL 9.4 is already around the corner to be released in May and 9.0 is going to be 2 years old. It’s certainly possible they have moved on to a newer minor release.
Hi, I actually was planning that already to be the next video but some other matters were taking my attention which has delayed new videos for a while. I will do what I can to produce a video eventually. On the bright side, I have already researched the points for the future LVM videos back in January and also have reimagined how I should make the content so they are higher quality and stay relevant for longer. Thank you for watching the videos, you are much appreciated!
