You can use the the installimage script to install the following operating systems:
| Operating System | Versions |
|---|---|
| Arch Linux latest | Minimal (64-Bit) |
| CentOS Stream 9 | Base (64-Bit) |
| Alma Linux 8 | Base (64-Bit) |
| Alma Linux 9 | Base (64-Bit) |
| Rocky Linux 8 | Base (64-Bit) |
| Rocky Linux 9 | Base (64-Bit) |
| Debian 11 (Bullseye) | Base (64-Bit) |
| Debian 12 (Bookworm) | Base (64-Bit) |
| Ubuntu 20 LTS (Focal Fossa) | Minimal (64-Bit) |
| Ubuntu 22 LTS (Jammy Jellyfish) | Base (64-Bit) |
| Ubuntu 24.04 LTS (Noble Numbat) | Base (64-Bit) |
The minimal images generally contain no software other than SSH, giving you a more freedom to adapt things to your usecase.
The LAMP images contain "Linux, Apache, MySQL and PHP".
You can find more information on how to install these operating systems on your server on this page.
What changes are made to the distributions?
Our standard images generally contain no additional or modified drivers or other software (eg. for RAID controllers). Our support teams update the images regularly.
Software
Each image contains software for all available installation options (software RAID and LVM) and file systems (ext2/3/4, reiserfs, xfs).
Boot loader
GRUB2 is the preferred boot loader and is used when it is supported by the operating system tools (like YAST). Otherwise GRUB (GRUB legacy) is used. The usage of LILO is no longer supported.
The boot loader configuration is adjusted so that any graphics mode is disabled nomodeset.
Network
The network configuration is pre-configured so that there are no restrictions. No firewall is enabled by default, but we recommend our users enable one as part of their system setup.
Drives/RAID
If software RAID is used, the RAID verification is set to a random time.
Time (NTP/Chrony/systemd-timesyncd)
The configuration is adjusted so that the Hetzner NTP servers are used. The preference is to use systemd-timesyncd if available, as it provides a strict client mode.
Package repositories
Provided that Hetzner has a mirror of the distribution, this gets used by default and is pre-configured, along with another mirror.
