How to make portable CentOS 8 bootable USB drive | How to install CentOS 8 on Dell R630

If you watched my channel long enough, you'll notice that I carry around with me a SanDisk Ultra Fit 64GB USB drive that has a portable CentOS 7 Linux installation. On this drive I also have a variety of tools for testing and updating/flashing firmware, which makes it very convenient to quickly test and update server equipment. Many viewers have contacted me asking me how I made a portable CentOS 7 Linux installation on a USB drive, and so I will demonstrate how to that with CentOS 8 Linux. Consequently, I'll also be showing you how to install CentOS 8 Linux on a Dell PowerEdge R630 server.

After watching your server videos. Found a Dell R710. Took out the fans and cleaned off the dust. This video will help with the next part. It is my home lap server.

Please keep the videos coming.

Wanted to install CentOS 8 to a flash drive, this video really helped! Thanks for explaining the process!

Another good video, thx! Think its possible to do a part 2, installing all the packages you use? I love following you along and try stuff, just not sure what all is needed or how to grab all the required tools (not a linux guy) yet! Thx again! 👍🏻

Thanks! Keep the great videos coming!

Ah-! Thank you for pointing me here. I never thought of installing CentOS on USB. Thought you were using the CentOS LiveCD USB as your Diagnostic USB. As always thank you for a very detailed Video. So I am assuming you boot from the target CentOS installed USB and download/offload utils and fw/drivers for updating/diag of servers?

[andriitarykin]

Just like from me because it's "Art of Server"! ;-)

Thank you for the update using CentOS 8. Appreciate it. I was wondering I would like to leverage the after of creating the bootable USB. All things under one USB disk using Ventoy. I know that there are multiple partitions created but want to set the CentOS usb as a single ISO bootable from a stick that has other tools on it. Like a master of one. Any ideas?

[michaelrapp]

Make a updated version please since CentOS8 is gone

I followed the same steps in the video, on the screen I get
Booting from Hard drive C:
GRUB
from there it does not continue, I am doing the installation with USB that is inside

[DylanCyr]

Couple of questions - what was the initial version of CentOS you used for the install, I see they had minimal, boot, dvd, etc in their download lists. I also saw that CentOS isn't being developed anymore - are you still using it or have you switched to another distro?

[Theedyy]

great video, you said in the beginning of the video that you have on the usb drive hardware testing tools, can you name them please. Thank you.

What other software and such do you put on the portable drive? I believe all of my servers are up to date but I was going to try to find something to check if I need any updates.

Ok I hope not go too far off the subject, but I have a R630 and MD1220, I was thinking of running ubuntu server since i have to pay for red hat, now my question is, can i use the perc h810 ono the md1220 and use hard drive above the 2TB?

centos 8 USB installation media works well on Virtual machines
but, installing on PC takes to emergency mode. /dev/root not found
All usb creators failed to successfully install.
proper way to edit boot command line is most welcome.

Good afternoon, a query in the case of the DELL R630 server which CENTOS distribution would be the most appropriate

[MrFooSteven]

Is that literally how easy it is? I'm currently using Clonezilla to clone from a SSD to the USB drive(the SSD has my installed Centos 8 apps, settings, etc). Hopefully it'll work.
Btw, do you know if its possible to ENCRYPT the linux install or USB using TRUECRYPT??
I use it on some Windows systems, but have never encrypted a Linux install(SSD or USB) using it.

I allways being using the DVD live from centos 7, I use it a lot, and it save me a lot of times too, but right now, I had being some troubles making restores from servers in RHEL 7, my ackup command is somethink like this: rsync -aAXv / --exclude={"/dev/*", "/proc/*", "/sys/*", "/tmp/*", "/run/*", "/mnt/*", "/media/*", "/lost+found", "/gridctl/*", "/or12cr12/*", "/commvault/*"} /backup/`hostname`, that is into the real server before anything, for example a update of release, well image that the update fail, I boot within centos live, mount all filesystem into /mnt/sysimage and run this: rsync -aAXv --delete --exclude="lost+found" /backup/ /mnt/sysimage/
, well I had some problems using X on rsync command, maybe need centos 8 live, if I create one like you did, it will work for any server? you know?
