Installation Preparations ​

This section describes the compatibility of the hardware and software and the related configurations and preparations required for the installation.

Obtaining the Installation Source ​

Obtain the openEuler release package and verification file before the installation.

Perform the following operations to obtain the openEuler release package:

1. Visit the openEuler website.
2. Click Downloads.
3. Click Community Editions. The version list is displayed.
4. Click Download on the right of openEuler 22.03 LTS SP2.
5. Download the required openEuler release package and the corresponding verification file based on the architecture and scenario.
   1. If the architecture is AArch64:
      1. Click AArch64.
      2. If you install openEuler from a local source, download the Offline Standard ISO or Offline Everything ISO release package openEuler-22.03-LTS-SP2-(everything-)aarch64-dvd.iso to the local host.
      3. If you install openEuler through the network, download the Network Install ISO release package openEuler-22.03-LTS-SP2-netinst-aarch64-dvd.iso to the local host.
   2. If the architecture is x86_64:
      1. Click x86_64.
      2. If you install openEuler from a local source, download the Offline Standard ISO or Offline Everything ISO release package openEuler-22.03-LTS-SP2-(everything-)x86_64-dvd.iso to the local host.
      3. If you install openEuler through the network, download the Network Install ISO release package openEuler-22.03-LTS-SP2-netinst-x86_64-dvd.iso to the local host.

• When the network is available, install the environment on the network because the ISO release package is small.
• The release package of the AArch64 architecture supports the UEFI mode, while the release package of the x86_64 architecture supports both the UEFI and Legacy modes.

Release Package Integrity Check ​

Introduction ​

To prevent the software package from being incompletely downloaded due to network or storage device faults during transmission, you need to verify the integrity of the software package after obtaining it. Only the software package that passes the verification can be installed.

Compare the verification value recorded in the verification file with the .iso file verification value calculated manually to check whether the software package passes the verification. If the values are consistent, the .iso file is not damaged. Otherwise, the file is damaged and you need to obtain it again.

Prerequisites ​

Before verifying the integrity of the release package, prepare the following files:

• ISO file: openEuler-22.03-LTS-SP2-aarch64-dvd.iso
• Verification file: Copy and save the Integrity Check SHA256 value to a local file.

Procedures ​

To verify the file integrity, perform the following operations:

1. Calculate the SHA256 verification value of the file. Run the following command:

   shell

   sha256sum openEuler-22.03-LTS-SP2-aarch64-dvd.iso

   After the command is run, the verification value is displayed.

2. Check whether the calculated value is the same as that of the saved SHA256 value.

   If the verification values are consistent, the .iso file is not damaged. If they are inconsistent, you can confirm that the file is damaged and you need to obtain the file again.

Installation Requirements for PMs ​

To install the openEuler OS on a PM, the PM must meet the following requirements.

Hardware Compatibility ​

You need to take hardware compatibility into account during openEuler installation. Compatibility List describes the types of supported servers.

Minimum Hardware Specifications ​

Table 2 lists the minimum hardware specifications supported by openEuler.

Table 2 Minimum hardware specifications

Installation Requirements for VMs ​

To install the openEuler OS on a VM, the PM must meet the following requirements.

Virtualization Platform Compatibility ​

When installing openEuler, pay attention to the compatibility of the virtualization platform. Currently, the following virtualization platforms are supported:

• A virtualization platform created by the virtualization components (openEuler as the host OS and QEMU and KVM provided in the release package) of openEuler
• x86 virtualization platform of Huawei public cloud

Minimum Virtualization Space ​

Table 3 lists the minimum virtualization space required by openEuler.
