It's possible if your Server provider has some kind of remote console.
I know servers from www.hetzner.de come with remote console/LARA which allows you to install CentOS yourself.
Usually though when providers dont offer CentOS, its because of some hardware incompatability. There are some Realtek network adaptors which CentOS doesnt like without compiling extra drivers into the kernel.
Thanks for your answer.
Ahh.. Sorry. Maybe my question is confusing..
Maybe I should ask:
"How to install centos to the servers via LAN?"
Like I now just want to play with 3 servers I have in my home. I only have 1 monitor, 1 keyboard, and 1 mouse. I know I just can unplug the monitor and plugin again to another box if I want to install that box.
But, I just wonder if I can just do it remotely via LAN from 1 pc to reload the os of the others servers... Is it possible? or the only way just unplug and plug the monitor and keyboard cables?
A regular KVM would be the way to go. You can share the same keyboard and monitor with all your boxes at the flick of a switch (or key sequence).
Alternatively, if your servers support PXE, you can you setup your own netboot server, and boot each of your servers off the network. However, you would need to boot them off the network every time even after the install, unless you connected back to them locally and changed the bios to boot off the hard drive.
