CentOS

Hi, is DefaultTimeoutStartSec related to every systemd unit? I am asking this because generally during boot I notice some process hung and the timer says: xx seconds / 90 seconds (the default settings). Today I saw a similar behavior with rc.local but the timer reported xx seconds / no limit. So my ...

I just found this:

and works fine.

It seems "-D" (daemonize) option is not a good thing in my previous systemd unit file, which doesn't make sense for me.
Can anyone explain me this?
Thank you!

Hi, I am trying to create a very simple systemd unit service, in attemp to manage "iperf" (bandwidth measurement tool). I installed iperf with yum and created this file: # cat /etc/systemd/system/iperf.service [Unit] Description=iperf After=network.target [Service] ExecStart=/usr/bin/iperf -s -D Exe...

If your machine is in UEFI mode then CentOS 7 should boot and run in UEFI mode on it. It's also secure boot enabled too though that is dependent on UEFI being enabled and in use. The best way to create a USB stick from one of our iso image files is to just use dd.

Thank you again

Hi TrevorH, thank you very much for your great explaination. So the issue was definitely not my BIOS settings (Secure Boot On), but my installation source was "wrong"? In other way, there is no a different way to install CentOS in UEFI mode: I simply install CentOS as I always did in the past, and i...

Hi TrevorH, frankly, I don't remember if I used CD or USB stick. I also noticed /boot/grub2/device.map file's content: (hd0) /dev/sdc (hd1) /dev/sdc so, assuming that sdc is my actual hard disk where CentOS is installed, I changed (hd1) /dev/sdc to (hd1) /dev/sda and re-ran grub2-mkconfig -o /boot/g...

Hi tried with grub prompt first, I got this result: grub> set pager=1 grub> ls (hd0) (hd0,msdos2) (hd0,msdos1) (hd1) (hd2) grub> set root=(hd0,msods1) grub> chainloader +1 error: invalid signature grub> set root=(hd0,msdos2) grub> chainloader +1 error: invalid signature grub> how can I fix this?

Hi TrevorH,

because (I guess) at time I installed CentOS on my Desktop, Secure Boot was enabled.
Could be?

Hi, on my Desktop PC I have two hard disks (SSD):I installed Windows 10 on /dev/sda and CentOS7 on /dev/sdc. Windows 10 is installed in UEFI mode, CentOS is not. Currently I need to enter UEFI bios everytime I need to select OS to start. Is it POSSIBLE to configure grub in order to boot Windows 10? ...

Sorry, I just realized that the inst.repo in PXE's configuration is mandatory, an allows "bootstrap" of installation process.
--url in kickstart belongs to the actual RPM repository, in order to install core, packages, and so on.
