Kerrrighed installation and setup guide in 2022

----Notes----

I do not know if anyone would want to use Kerrighed in 2022, but if you went down the same rabbit hole I did then this guide will help you.

I have found that kerrighed will sometimes not run on virtualbox when I/O apci is enabled in virtualbox on AMD processors. It will compile, but it will kernel panic when booting.

----You will need----

Copy of linux kernel 2.6.20: https://mirrors.edge.kernel.org/pub/linux/kernel/v2.6/linux-2.6.20.tar.bz2

Kerrighed source code found in this respository

A copy of Ubuntu Hardy found here: https://old-releases.ubuntu.com/releases/hardy/

specifically this works: https://old-releases.ubuntu.com/releases/hardy/ubuntu-8.04-server-amd64.iso

A copy of virtualbox

Ubuntu Hardy SETUP INSTRUCTIONS

Boot the Ubuntu ISO in virtualbox and follow the setup instructions

Do not try to download any extra packages because the apt repository will not work

Once initial installation complete the first thing you will need to do is repair the apt sources list.

----Repair APT----

A copy of the updated sources.list file can be found here, but if you want to do it manually you will need to replace all the archive.ubuntu.com links with old-releases.ubuntu.com.

Once that is fixed you should be able to run "apt-get update" or "aptitude update"

---Install Required Tools---

aptitude install dhcp3-server tftpd-hpa syslinux nfs-kernel-server nfs-common debootstrap

---Run some Commands---

1. cp /usr/lib/syslinux/pxelinux.0 /var/lib/tftpboot
2. mkdir /var/lib/tftpboot/pxelinux.cfg
3. cp /boot/vmlinuz-<KERNEL_VERSION> /boot/initrd.img-<KERNEL_VERSION> /var/lib/tftpboot/

--Configure Services---

copies of the files that need to be edited are included in this repo under "config files" edit them when appropriate because they may not work for all builds

Edit the files:

1. /etc/default/dhcp3-server
2. /etc/dhcp3/dhcpd.conf
3. /etc/default/tftp-hpa
4. /etc/exports
5. /var/lib/tftpboot/pxelinux.cfg/default

---Configure Chroot----

1. debootstrap --arch amd64 hardy /nfsroot/kerrighed http://old-releases.ubuntu.com/ubuntu/
2. chroot /nfsroot/kerrighed
3. passwd
4. mount -t proc none /proc

now edit the sources.list to be like the one on the host.

5. aptitude update
6. apt-get install dhcp3-common nfs-common nfsbooted openssh-server

edit the files in "chroot config files"

7. ln -sf /etc/network/if-up.d/mountnfs /etc/rcS.d/S34mountnfs
8. adduser "username"

----Setup Kerrighed----

1. apt-get install automake autoconf libtool pkg-config gawk rsync bzip2 gcc-3.3 libncurses5 libncurses5-dev wget lsb-release xmlto patchutils xutils-dev build-essential openssh-server ntp

2. copy kernel and kerrighed source into /usr/src

3. cd /usr/src

4. tar zxf kerrighed-2.4.1.tar.gz

5. tar jxf linux-2.6.20.tar.bz2

6. cd /usr/src/kerrighed-VERSION/modules

7. ./configure --with-kernel=/usr/src/linux-2.6.20 CC=gcc-3.3

8. cd kernel

9. make defconfig

10. make menuconfig

11. make kernel

12. make

13. make kernel-install

14. make install

15. ldconfig

16. mkdir /config

17. cp /nfsroot/kerrighed/boot/vmlinuz-2.6.20-krg /var/lib/tftpboot/

18. exit

19. reboot

----Testing setup----

Everything should work now

commands that should work

1.krgadm cluster start 2. krgadm cluster status 3. free -m should show combined ram
