Is it possible to install Centos using PXE+tftp ? All i've found is a netinstall but it requires a CDROM to be in the server's drive (and I cannot access the server physically).

I cannot find any detailed step by step guide. I'm sure it may exist; if someone has a link handy ...

Do you have another computer on the same broadcast domain as the target computer, and do you have low-enough level access to the machine to be able to change BIOS settings to let it boot via the Ethernet card(s)? Otherwise, you're not going to be able to do much.

If the remote access you have is IPMI/DRAC/some other integrated remote access card, these will often (always?) provide the ability to mount an .ISO as a drive and export it to the target computer. You may wish to consider this approach.

As far as a way to PXE boot CentOS 5.5, we use Cobbler to do this all the time; it's a simple "yum install cobbler" and then take it from there. However, it's hardly plug-and-play, and there's likely to be a simpler approach if you only need to do this for one machine.

One last postscript: why 5.5 and not 5.6?

Didn't knew of Cobbler but as you say it's the very hard path ... not any simpler approach with PXE/TFTP there must be someway ... (5.5 because it's a requirement) – Disco May 9 '11 at 12:50

We do this all the time. I highly suggest setting up a menu if you're going to be installing multiple flavors/versions. It's pretty convenient. Of course, you can also completely automate this by putting a kickstart config file in your PXE boot definitions.

I haven't tested this myself, but I've had this link bookmarked about installing CentOS remotely using VNC:

Hopefully that's helpful!
