      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 community.
      2. Choose Downloads > Community Editions. Then, locate the target version openEuler 20.03 LTS. Then, click Download.
      3. Select the openEuler release package and verification file to be downloaded based on the architecture of the environment to be installed.
        • If the AArch64 architecture is used:

          1. Click AArch64.
          2. Download the offline standard ISO or offline everything ISO to the local host.
        • If the x86_64 architecture is used:

          1. Click x86_64.
          2. Download the offline standard ISO or offline everything ISO to the local host.

      Release Package Integrity Check

      NOTE: This section describes how to verify the integrity of the release package in the AArch64 architecture. The procedure for verifying the integrity of the release package in the x86_64 architecture is the same.

      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 packages that pass 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 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.

      Prerequisites

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

      ISO file: openEuler-20.03-LTS-aarch64-dvd.iso

      Verification file: Copy and save the Integrity Check SHA256 value to a local file.

      Procedure

      To verify the file integrity, perform the following operations:

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

        sha256sum openEuler-20.03-LTS-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 hardware compatibility and minimum hardware requirements.

      Hardware Compatibility

      You need to take hardware compatibility into account during openEuler installation. Table 1 describes the types of supported servers.

      NOTE:

      • TaiShan 200 servers are backed by Huawei Kunpeng 920 processors.
      • Currently, only Huawei TaiShan and FusionServer Pro servers are supported. More servers from other vendors will be supported in the future.
