To run Guix on a server hosted by Kimsufi, click on the netboot tab then select rescue64-pro and restart.
OVH will email you the credentials required to ssh into a Debian system.
Now you can run the "install guix from see Binary Installation in GNU Guix" steps:
wget https://git.savannah.gnu.org/cgit/guix.git/plain/etc/guix-install.sh chmod +x guix-install.sh ./guix-install.sh guix pull
Partition the drives and format them, first stop the raid array:
mdadm --stop /dev/md127 mdadm --zero-superblock /dev/sda2 /dev/sdb2
Then wipe the disks and set up the partitions, we will create a RAID 1 array.
wipefs -a /dev/sda wipefs -a /dev/sdb parted /dev/sda --align=opt -s -m -- mklabel gpt parted /dev/sda --align=opt -s -m -- \ mkpart bios_grub 1049kb 512MiB \ set 1 bios_grub on parted /dev/sda --align=opt -s -m -- \ mkpart primary 512MiB -512MiB set 2 raid on parted /dev/sda --align=opt -s -m -- mkpart primary linux-swap 512MiB 100% parted /dev/sdb --align=opt -s -m -- mklabel gpt parted /dev/sdb --align=opt -s -m -- \ mkpart bios_grub 1049kb 512MiB \ set 1 bios_grub on parted /dev/sdb --align=opt -s -m -- \ mkpart primary 512MiB -512MiB \ set 2 raid on parted /dev/sdb --align=opt -s -m -- mkpart primary linux-swap 512MiB 100%
Create the array:
mdadm --create /dev/md127 --level=1 --raid-disks=2 \ --metadata=0.90 /dev/sda2 /dev/sdb2
Now create file systems on the relevant partitions, first the boot partitions:
mkfs.ext4 /dev/sda1 mkfs.ext4 /dev/sdb1
Then the root partition:
mkfs.ext4 /dev/md127
Initialize the swap partitions:
mkswap /dev/sda3 swapon /dev/sda3 mkswap /dev/sdb3 swapon /dev/sdb3
Mount the guix drive:
mkdir /mnt/guix mount /dev/md127 /mnt/guix
Now is time to write an operating system declaration os.scm file; here is a sample:
(use-modules (gnu) (guix)) (use-service-modules networking ssh vpn virtualization sysctl admin mcron) (use-package-modules ssh tls tmux vpn virtualization) (operating-system (host-name "kimsufi") (bootloader (bootloader-configuration (bootloader grub-bootloader) (targets (list "/dev/sda" "/dev/sdb")) (terminal-outputs '(console)))) ;; Add a kernel module for RAID-1 (aka. "mirror"). (initrd-modules (cons* "raid1" %base-initrd-modules)) (mapped-devices (list (mapped-device (source (list "/dev/sda2" "/dev/sdb2")) (target "/dev/md127") (type raid-device-mapping)))) (swap-devices (list (swap-space (target "/dev/sda3")) (swap-space (target "/dev/sdb3")))) (issue ;; Default contents for /etc/issue. "\ This is the GNU system at Kimsufi. Welcome.\n") (file-systems (cons* (file-system (mount-point "/") (device "/dev/md127") (type "ext4") (dependencies mapped-devices)) %base-file-systems)) (users (cons (user-account (name "guix") (comment "guix") (group "users") (supplementary-groups '("wheel")) (home-directory "/home/guix")) %base-user-accounts)) (sudoers-file (plain-file "sudoers" "\ root ALL=(ALL) ALL %wheel ALL=(ALL) ALL guix ALL=(ALL) NOPASSWD:ALL\n")) ;; Globally-installed packages. (packages (cons* tmux gnutls wireguard-tools %base-packages)) (services (cons* (service static-networking-service-type (list (static-networking (addresses (list (network-address (device "enp3s0") (value "server-ip-address/24")))) (routes (list (network-route (destination "default") (gateway "server-gateway")))) (name-servers '("213.186.33.99"))))) (service unattended-upgrade-service-type) (service openssh-service-type (openssh-configuration (openssh openssh-sans-x) (permit-root-login #f) (authorized-keys `(("guix" ,(plain-file "ssh-key-name.pub" "ssh-public-key-content")))))) (modify-services %base-services (sysctl-service-type config => (sysctl-configuration (settings (append '(("net.ipv6.conf.all.autoconf" . "0") ("net.ipv6.conf.all.accept_ra" . "0")) %default-sysctl-settings))))))))
Kom ihåg att ersätta variablerna server-ip-address, server-gateway, ssh-key-name och ssh-public-key-content med dina egna värden.
The gateway is the last usable IP in your block so if you have a server with an IP of ‘37.187.79.10’ then its gateway will be ‘37.187.79.254’.
Transfer your operating system declaration os.scm file on the server
via the scp
or sftp
commands.
Now all that is left is to install Guix with a guix system init
and
restart.
However we first need to set up a chroot, because the root partition of the rescue system is mounted on an aufs partition and if you try to install Guix it will fail at the GRUB install step complaining about the canonical path of "aufs".
Install packages that will be used in the chroot:
guix install bash-static parted util-linux-with-udev coreutils guix
Then run the following to create directories needed for the chroot:
cd /mnt && \ mkdir -p bin etc gnu/store root/.guix-profile/ root/.config/guix/current \ var/guix proc sys dev
Copy the host resolv.conf in the chroot:
cp /etc/resolv.conf etc/
Mount block devices, the store and its database and the current guix config:
mount --rbind /proc /mnt/proc mount --rbind /sys /mnt/sys mount --rbind /dev /mnt/dev mount --rbind /var/guix/ var/guix/ mount --rbind /gnu/store gnu/store/ mount --rbind /root/.config/ root/.config/ mount --rbind /root/.guix-profile/bin/ bin mount --rbind /root/.guix-profile root/.guix-profile/
Chroot in /mnt and install the system:
chroot /mnt/ /bin/bash guix system init /root/os.scm /guix
Finally, from the web user interface (UI), change ‘netboot’ to ‘boot to disk’ and restart (also from the web UI).
Wait a few minutes and try to ssh with ssh
guix@server-ip-address> -i path-to-your-ssh-key
You should have a Guix system up and running on Kimsufi; congratulations!
