RHEL 7 and basic systemd commands (George Magklaras)

[@TrungLe-lw4zm]

Thanks for the video. It is still relevant even today (on Fedora 31)

[@aijaz4441]

Excellent explanation of SystemD along with comparision with Init systems.

[@deborah_chrysoprase]

This was immensely helpful in helping me learn to implement systemd scripts. I was quite lost at first but I've got a strong handle on this after some trial and error. Thank you!

[@hadinasiri7678]

I would say keep the tutorials coming. good job Georgios

[@efremdedwards]

Wow. Great demo+Lesson. Thanks for helping me with bridging RHEL 6 and RHEL 7

[@silinalexandr]

Great review Georgios. Thank you!

[@theepistolatory]

You are very welcome!

[@gargmayanktux]

Nice demonstration between init v/s systemd.

[@babasaly1]

prior to rel 7, I used the command init [run-leve] to switch between runlevel without the need of reboot. Any option in rel 7 to switch between targets withtout the reboot ?

[@theepistolatory]

Yes, this is a nice question that points out how to avoid the reboot. You can switch between targets (the new name for runlevels) by using the: systemctl isolate command . For example: systemctl isolate multi-user.target to switch from the graphical to multi-user mode (no login screen and X, old runlevel 3) will not reboot the system, but it will switch to the desired target immediately. systemctl isolate does NOT modify permanently the default target.

Georgios Magklaras Thank you

[@brunotartaro92]

Thank you Georgios!

[@fernando26recor]

great video, thank you!

[@Dirtbag359]

Did they really have to make it *systemctrl*? I really wish they would have come up with an alternate shorthand command like sysdc or even sysdctrl. Typing systemc to get it an auto-complete option into systemctrl isn't a big deal for one or two commands but if your working on something for an hour or two it can get preetty tedious. Especially when for service all you needed was serv(tab) -> sevice.

[@johnlewis6430]

Don't like it, make an alias.

[@Dirtbag359]

I do for my own personal system but its just something I wish was set right out of the box. I work with other peoples systems so if I want it I have to to set it up each time (not the end of the world but it would be kind of like having to set two or three bookmarks for your favorite site every time you opened a browser, Granted not a lot of companies seem to be using SystemD based systems but that day is coming. Though ironically enough I've come around to SystemD in the last couple months since writing that post in early September (man its been 2 months already).

[@logidet]

+Dirtbag359 it's *systemctl*. Like *journalctl*, *machinectl*, *timedatectl*, etc.

[@himaniverma4877]

Very nice explained...

[@shaggy8198]

Thank you Sir for basic systemd Commands i like your video I like to ask you can give some information about mariadb on linux 7 Thank you

[@xty007]

Thanks for the lesson :) very good \o/

[@zealvora]

Great Video Georgios :)

[@sonsukh]

could you please upload a video for bonding or network teming

[@theepistolatory]

I will make a screencast demonstrating the NIC bonding at the earliest opportunity.

[@dheerajtripathi011]

Georgios Magklaras i guess here in RHEL 7 we have the concept of teaming and bonding was used in earlier ..... Am i right ?

[@AdrianColley]

21 minutes on systemd and not a single line of a unit file was displayed.

[@theepistolatory]

Hei Adrian. This is a very valid point. Indeed, I could have basically mentioned unit files, however, this video focused on the commands and not so on the underlying configuration structure. I do plan to produce more videos where unit files are demo-ed in detail. Thanks for your feedback!

[@sozinonl]

very well exposed. thank you for this video!

[@cyberhard]

Dirtbag359 if it bothers you, why not make an alias?

[@linuxworldwithgk]

Gud explanation

[@r4zib]

Thanks .... may i ask for email ??

[@onnozweers]

Ευχαριστώ!

[@theepistolatory]

Παρακαλώ.
