[edit] FreeBSD bootonly
The first step to installing FreeBSD via netboot is to acquire FreeBSD. We'll be using the bootonly-iso, this can be fetched at your nearest ftp.
Download the bootonly-iso:
fetch ftp://ftp.freebsd.org/pub/FreeBSD/ISO-IMAGES-i386/8.2/FreeBSD-8.2-RELEASE-i386-bootonly.iso fetch ftp://ftp.freebsd.org/pub/FreeBSD/ISO-IMAGES-amd64/8.2/FreeBSD-8.2-RELEASE-amd64-bootonly.iso
Mount the iso-image and copy the contents to some location:
mdconfig -a -t vnode -f FreeBSD-8.2-RELEASE-i386-bootonly.iso mount_cd9660 /dev/md0 /mnt mkdir /usr/local/pxeboot cp -R /mnt/ /usr/local/pxeboot umount /mnt mdconfig -d -u 0
The main reason for copying the cd is to edit the file /boot/loader.conf adding the following line:
echo 'vfs.root.mountfrom="ufs:/dev/md0"' >> /usr/local/pxeboot/boot/loader.conf
This will cause the lovable FreeBSD sysinstall to start. The pxeboot will mount the rootfs from the file mfsroot.gz instead of the default of mounting a NFS-root.
[edit] NIC with PXE boot
For the pxeboot to work you might have to update your NIC with new firmware. See your manufacturer homepage for more information.
[edit] TFTP
Next up is starting a tftp-server from which the firmware can load the network bootstrap program from. This is easiest done by using inetd, remove the leading # from the following line in the file /etc/inetd.conf.
#tftp dgram udp wait root /usr/libexec/tftpd tftpd -l -s /tftpboot
Make the tftpboot directory and copy the boot/pxeboot file to it.
mkdir /tftpboot cp /usr/local/pxeboot/boot/pxeboot /tftpboot/
Then start inetd by adding it to rc.conf and starting it.
echo 'inetd_enable="YES"' >> /etc/rc.conf /etc/rc.d/inetd start
It can be a good idea to start a tail of messages and xferlog file to see what is happening. In another terminal run:
tail -f /var/log/messages /var/log/xferlog
[edit] DHCP
Now it's time for the DHCP-server that the firmware will query to get address and path to the network bootstrap program.
Install isc-dhcp31-server
pkg_add -r isc-dhcp31-server
Edit /usr/local/etc/dhcpd.conf adding the following lines.
ddns-update-style none; server-name "pxe-gw"; # name of the tftp-server server-identifier 172.24.0.4; # address of the tftp-server next-server 172.24.0.4; # address of the NFS-server
subnet 172.24.0.0 netmask 255.255.255.0 { range 172.24.0.137 172.24.0.253; option routers 172.24.0.1; option root-path "/usr/local/pxeboot"; # root-path for NFS filename "pxeboot"; # filename of NBP (network bootstrap program) }
[edit] NFS
Add the pxeboot directory to nfs exports file
echo '/usr/local/pxeboot -alldirs -maproot=root -ro' >> /etc/exports
Enable NFS in rc.conf
echo 'nfs_server_enable="YES"' >> /etc/rc.conf
Start nfsd
/etc/rc.d/nfsd start
Reboot your computer and select PXE-boot you should now enter sysinstall, have a nice day!
