Install the OS by auto-installation

Autoinstall is a tool to install and reinstall an operating system on a dedicated server automatically through a control panel. Only the following are available for installation operating system distributions prepared by the Selectel team. If you want to use your image, install the OS manually.

The OS will be installed on the first disk, according to the order of disk installation — NVMe → SSD → HDD. If you need to install the OS on another disk, install the OS manually.

For your information

When the OS installation is complete, the number of authorization attempts when connecting via SSH will be limited. After 10 unsuccessful password attempts from one IP address, that IP address will be blocked for 24 hours. If you forget your server password, you can reset and restore it.

  1. В control panels go to Servers and hardwareServers.
  2. Open the server page → tab Operating system.
  3. Click Change the OS configuration.
  4. Optional: select SSH key. You can add a new public SSH key or select one from the repository for SSH keys;
  5. Optional: enter user data. You can specify user data only for servers in a ready configuration. The field is not available for all operating systems;
  6. Select distribution for installation.
  7. Optional: partition the disks. By default, the optimal RAID type is defined and only partitioned disks and disks in RAID are partitioned.
  8. Click Set. Installation can take from 7 to 60 minutes, depending on the performance of the server and the distribution selected. If it takes longer than that, file a ticket.
  9. After the OS is installed, a password will be generated to connect to the server. The password can be viewed in control panels on the server page → tab Operating system. It is available for viewing 24 hours after the OS installation is complete.

Partition the disks

You can partition disks in the automatic OS installation process in step 5.

You can perform partitioning for each disk separately for the following operating systems: Ubuntu 24.04LTS, Ubuntu 22.04LTS, Ubuntu 20.04LTS, AlmaLinux 9.2x86_64, Oracle 9x86_64, Debian 12x86_64, Debian 11x86_64, Proxmox, Rocky 9.2x86_64.

  1. Click Manage disk partitioning.
  2. Select the desired disk.
  3. Optional: press Add to RAID.
  4. If you have assembled disks in RAID, or want to RAID a single disk, define the RAID type:
    • RAID1 — mirroring. All data is written to at least two separate physical disks in a RAID set. The array is built from selected disks;
    • RAID0 — RAID distribution, disk striping. When RAID0 is selected, if one of the disks fails, all data will be lost with no possibility of recovery;
    • RAID10 (suitable only for configurations with at least four disks) — mirroring, disk striping. All data is written sequentially to multiple disks.
  5. Check the disk partitioning or RAID. The partitioning table will show the mandatory partitions with mount points — /boot, /, swap.
  6. Optional: press Add a section. The choice of partition file system depends on the OS limitations.
  7. If you are installing an OS on the disk, make sure there is no unmapped area left on the disk.
  8. Go back to step 6 in the automatic OS installation process.

OS distributions for automatic installation

Periodically, we disable the ability to auto-install unclaimed configurations and configurations that have reached their official End Of Life (EOL).
