Installing openSUSE Tumbleweed on a Dedibox

By Mathieu CARBONNEAUX

This small tutorial for installing openSUSE Tumbleweed on a Dedibox.

First step is to install a Linux distribution using the online console installation system, for example Ubuntu.

Then log into the machine and switch to root and download the necessary images for installation.

user@sd-xxxxx :~ # sudo su -
root@sd-xxxxx :~ # cd /boot
root@sd-xxxxx :~ # wget --output-document=vmlinuz.install http://download.opensuse.org/tumbleweed/repo/oss/boot/x86_64/loader/linux
root@sd-xxxxx :~ # wget --output-document=initrd.install http://download.opensuse.org/tumbleweed/repo/oss/boot/x86_64/loader/initrd

Retrieve the machine’s IP via ifconfig (example 192.168.10.10).

root@sd-xxxxx :~# ifconfig
eno1      Link encap:Ethernet  HWaddr xx:xx:xx:xx:xx:xx
          inet addr:192.168.10.10  Bcast:192.168.10.255  Mask:255.255.255.0

Find the DNS IP:

root@sd-xxxxx :~ # cat /etc/resolv.conf
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 192.168.10.1
search online.net

Find the mduuid of the boot partition:

root@sd-xxxxx :~ # mount | grep boot
/dev/md0 on /boot type ext4 (rw,relatime,stripe=4,data=ordered)
root@sd-xxxxx :~ # mdadm --detail /dev/md0 | grep \/dev
/dev/md0:
      0       8        2        0      active sync   /dev/sda2
      1       8       18        1      active sync   /dev/sdb2
root@sd-xxxxx :~ # lsblk  -f /dev/sdb2
NAME  FSTYPE            LABEL            UUID                                 MOUNTPOINT
sdb2  linux_raid_member 62-210-136-200:0 f10e1a06-0cb2-1aeb-e92f-937476d3ea65
└─md0 ext4                               5b69725e-6914-463e-bf26-6b02a222f59c /boot

The uuid is the name at the end of the sdb2 line: ‘f10e1a06-0cb2-1aeb-e92f-937476d3ea65’.

This is the number to use to define the root but without the ‘-’.

Modify the “/etc/grub.d/40_custom” file and add the following section at the end:

menuentry "openSUSE Tumbleweed" {
  set root='mduuid/f10e1a060cb21aebe92f937476d3ea65'
  linux /vmlinuz.install noapic usessh=1 sshpassword="12345678" install=http://download.opensuse.org/tumbleweed/repo/oss/ hostip=192.168.10.10 netmask=255.255.255.0 gateway=192.168.10.1 nameserver=192.168.10.1
  initrd /initrd.install
}

Edit the /etc/default/grub file to change GRUB_DEFAULT="openSUSE Tumbleweed".

To apply the change:

root@sd-xxxxx :~ # update-grub2

Reboot the server:

root@sd-xxxxx :~ # reboot

The server will restart on the openSUSE installer in SSH mode with x11forwarder.

Then since the installation is done in x11 mode, you need to have a local x11 server and connect via SSH to the server’s IP with the X11Forwarding option enabled.

If you’re on Windows: https://sourceforge.net/projects/xming/ and putty http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html

Configure the x11forwarding option: capture2menuputtyx111

On Linux:

root@sd-xxxxx :~ # ssh -X root@192.168.10.10
