I am pondering reinstalling a CentOS Linux server remotely, by installing CentOS' installer into /boot (GRUB) as per this tutorial: ganesh.me: Install Linux Servers Remotely

I notice that there are two different versions of vmlinuz and initrd.img in the CentOS 6 distribution:

What is each one for?

I think that the /isolinux/ ones are for booting a live CD using ISOLINUX, whereas the pxeboot ones are for booting CentOS from a PXE server. PXE booting is when you obtain the kernel and initrd from another server using a TFTP client built into the network interface. Typically you'll see something like "Network Boot" in the boot list in your BIOS.

  • So, that means that neither of the file sets is _intended_ for my usage scenario? Maybe some of the files (boot.iso, efiboot.img, efidisk.img, install.img) at [centos/6.5/os/x86_64/images/](http://mirror.de.leaseweb.net/centos/6.5/os/x86_64/images/) are fore me? – Nickolai Leschov Mar 25 '14 at 14:22
  • Looking at the link you provided, if you're just trying to find the files for the installer, and have a good internet connection on the server, then the PXE files should work for the installation. However, I have never performed this process before, so I can't say for certain. – zymhan Mar 26 '14 at 14:41

"Download the PXE boot initrd.img and vmlinuz files to your /boot."
