<https://www.linode.com/docs/guides/install-nixos-on-linode/#prepare-your-linode>

|
|
|
|
- shutdown linode
|
|
- delete existing disks and configuration profiles
|
|
- Create Disks
|
|
- `installer`: `ext4` `1280 MB`
|
|
- `swap`: `swap` `512 MB`
|
|
- `nixos`: `ext4` all remaining space
|
|
- Create two configuration profiles, one for the installer and one to boot NixOS. For each profile, disable all of the options under Filesystem/Boot Helpers and set the Configuration Profile to match the following:
|
|
- installer profile
|
|
- Label: installer
|
|
- Kernel: Direct Disk
|
|
- /dev/sda: nixos
|
|
- /dev/sdb: swap
|
|
- /dev/sdc: installer
|
|
- root / boot device: Standard: `/dev/sdc`
|
|
- nixos profile
|
|
- Label: nixos
|
|
- Kernel: GRUB 2
|
|
- /dev/sda: nixos
|
|
- /dev/sdb: swap
|
|
- root / boot device: Standard: `/dev/sda`
|
|
- Setup installer.
|
|
- rescue mode with installer as /dev/sda
|
|
- Open LISH
|
|
|
|
```bash
|
|
# Update SSL certificates to allow HTTPS connections:
|
|
update-ca-certificates
|
|
# set the iso url to a variable
|
|
iso=https://channels.nixos.org/nixos-24.11/latest-nixos-minimal-x86_64-linux.iso
|
|
# verify sda disk is installer (~1GB)
|
|
lsblk
|
|
curl -L https://channels.nixos.org/nixos-24.11/latest-nixos-minimal-x86_64-linux.iso.sha256
|
|
# Download the ISO, write it to the installer disk, and verify the checksum:
|
|
curl -L $iso | tee >(dd of=/dev/sda) | sha256sum
|
|
# verify the shas are the same then shutdown system
|
|
shutdown 0
|
|
```
|
|
|
|
- Boot the installer configuration profile and install nixos
|
|
(open GLISH and `sudo -i && passwd #simple pass` ssh into machine for easier copy paste, rerun `passwd` with a more secure password here if desired)
|
|
- mount /dev/sda /mnt
|
|
- swapon /dev/sdb
|
|
- nixos-generate-config --root /mnt
|
|
- cd /mnt/etc/nixos
|
|
|
|
- # TODO rewrite device modifiers like they say in the tutorial? I had issues with linode's device labeling so I am leaving it to uuids, this could bite me in the future idk
|
|
|
|
- copy `linode.nix` into remote server and import it into `configuration.nix`
|
|
- update ssh key for root user if needed
|
|
- `nixos-install`
|
|
- shutdown in linode, delete installer disk
|
|
- delete the installer configuration profile in linode, boot into nixos configuration profile
|
|
|
|
|
|
tada, should be able to ssh with root and ssh key defined in earlier in linode.nix
