Remote installation over NFS
the network.
Open your favorite text editor and just make the following entry in your
/etc/exports file
/mnt/cdrom 192.168.0.x
Here you would replace the x with the IP of the machine you are
installing Linux on. As an alternative, you can just export the directory
to everyone on your subnet in the following format
/mnt/cdrom address/netmask
/mnt/cdrom 192.168.0.0/255.255.255.0
This entry allows every machine from the subnet 192.168.0.0 to
access your NFS share over the network. After having edited the
/etc/exports file all you have to do is re-start the NFS server with the
following command.
bash#/etc/rc.d/init.d/nfs restart
Now check that the directory can be mounted by other hosts on your network
bash#mount 192.168.0.1:/mnt/cdrom /mnt/nfstest
Replace the IP address here by the IP address of the machine exporting the
cdrom. If you are able to mount the directory and access the contents then
you have successfully installed and configured the NFS server with the
share /mnt/cdrom over the Local Area Network.
Now you need to create the boot floppy that contains the kernel required
for network booting.
bash#cd /mnt/cdrom/images
Issue the following command to create the boot floppy
bash#dd if=./bootnet.img of=/dev/fd0
At this point take a deep breath and relax for the moment of truth
is just about to strike you. Three cheers to you for having just
accomplished a big and tough task.
Starting the Installation
Now insert the floppy you have made into your client machines. Before
booting off this floppy, make sure that the client machines' BIOS is set
to the following.
A,C,CDROM
On booting from the floppy you are asked all the usual questions
The only point of difference is the choice of Installation medium
which is the third screen of Install. At that point you enter the IP
address of your NFS Server and the path to the NFS share, which is
/mnt/cdrom.
The installation then proceeds as normal.
I would highly appreciate any feedback that you can send across.
