FreeBSD is a registered trademark of Wind River Systems, Inc. This is expected to change soon.
Intel, Celeron, EtherExpress, i386, i486, Itanium, Pentium, and Xeon are trademarks or registered trademarks of Intel Corporation or its subsidiaries in the United States and other countries.
Many of the designations used by manufacturers and sellers to distinguish their products are claimed as trademarks. Where those designations appear in this document, and the FreeBSD Project was aware of the trademark claim, the designations have been followed by the ``™'' or the ``®'' symbol.
Warning: This procedure will make the ``Server'' both insecure and dangerous, it is best to just keep the ``Server'' on its own hub and not in any way accessible by any machines other than the ``Clients''.
|Server||The machine offering netboot and install options.|
|Client||The machine that will have FreeBSD installed on it.|
Requires: Clients supporting the Intel PXE netboot option, an Ethernet connection.
Please let me know if you come across anything you have problems with or suggestions for additional documentation.
If you would like someone to train/implement a specific netinstall system for you, please send email so that we can discuss terms.
Make a directory /usr/tftpboot
Add this line to your /etc/inetd.conf:
tftp dgram udp wait nobody /usr/libexec/tftpd tftpd /usr/tftpboot
Add this to /etc/rc.conf:
Add this to /etc/exports:
/usr -alldirs -ro
Reboot to enable the new services or start them manually.
Set up tftp/pxe-boot directory:
Put pxeboot in the boot directory:
# rm -rf /usr/obj/* # cd /usr/src/sys/boot # make # cp /usr/src/sys/boot/i386/pxeldr/pxeboot /usr/tftpboot
Using the vndevice mount the kern.flp file and copy its contents to /usr/tftpboot:
# vnconfig vn0 kern.flp # associate a vndevice with the file # mount /dev/vn0 /mnt # mount it # cp -R /mnt /usr/tftpboot # copy the contents to /usr/tftpboot # umount /mnt # unmount it # vnconfig -u vn0 # disassociate the vndevice from the file
Compile a custom kernel for the clients (particularly to avoid the device config screen at boot) and stick it in /usr/tftpboot.
Make a special loader.rc to and install it in /usr/tftpboot/boot/loader.rc so that it does not prompt for the second disk, here is mine.
Extract the installer and helper utilities from the mfsroot disk and uncompress them, put them in /usr/tftpboot as well:
# vnconfig vn0 mfsroot.flp # associate a vndevice with the file # mount /dev/vn0 /mnt # mount it # cp /mnt/mfsroot.gz /usr/tftpboot # copy the contents to /usr/tftpboot # umount /mnt # unmount it # vnconfig -u vn0 # disassociate the vndevice from the file # cd /usr/tftpboot # get into the pxeboot directory # gunzip mfsroot.gz # uncompress the mfsroot
Make your sysinstall script install.cfg, you can use mine as a template, but you must edit it.
Copy the sysinstall script into the extracted and uncompressed mfsroot image:
# cd /usr/tftpboot # vnconfig vn0 mfsroot # mount /dev/vn0 /mnt # cp install.cfg /mnt # umount /mnt # vnconfig -u vn0
Put the install files in an NFS accessible location on the Server. Make a directory corresponding the 'nfs' directive in the install.cfg file and mirror the FreeBSD install files there, you will want it to look somewhat like this:
ABOUT.TXT TROUBLE.TXT compat20 floppies ports ERRATA.TXT UPGRADE.TXT compat21 games proflibs HARDWARE.TXT XF86336 compat22 info src INSTALL.TXT bin compat3x kern.flp LAYOUT.TXT catpages crypto manpages README.TXT cdrom.inf dict mfsroot.flp RELNOTES.TXT compat1x doc packages
Copy the compressed packages into the packages/All directory under nfs.
Make sure you have an INDEX file prepared in the packages directory. You can make your own INDEX entries like so:
alfred-1.0||/|Alfred install bootstrap||alfred@FreeBSD.org||||
Then you can install custom packages, particularly your own custom post-install package.
You can use the script pkgmaker.sh to create a custom package for post install, the idea is to have it install and configure any special things you may need done. pkgmaker is run in the directory above the package you wish to create with the single argument of the package (ie mypkg) which will then create a mypkg.tgz for you to include in your sysinstall package.
Inside your custom package dir you will want a file called PLIST which contains all the files that you wish to install and be incorporated into your package.
Since this package is in your install.cfg file it should be run and do the final configuration for you.
