      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 21.09.
      5. Download the required openEuler release package and the corresponding verification file based on the architecture and scenario.
        • AArch64 architecture:

          1. Click AArch64.
          2. If you install openEuler from a local source, download the Offline Standard ISO or Offline Everything ISO release package openEuler-21.09-(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-21.09-netinst-aarch64-dvd.iso to the local host.
        • x86_64 architecture:

          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-21.09-(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-21.09-netinst-x86_64-dvd.iso to the local host.

      fig NOTE:

      • 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

      fig 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 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, you need to prepare the following files:

      ISO file: openEuler-21.09-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:

        sha256sum openEuler-21.09-aarch64-dvd.iso
        

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

      2. Check whether the values obtained from the step 1 and step 2 are consistent.

        If the values are consistent, the ISO file is not damaged. Otherwise, the file is damaged and you need to obtain it 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. Table 1 describes the types of supported servers.

      fig 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.

      Table 1 Supported servers

      Server TypeServer NameServer Model
      Rack serverTaiShan 2002280 balanced model
      Rack serverFusionServer ProFusionServer Pro 2288H V5
      NOTE:
      The server must be configured with the Avago SAS3508 RAID controller card and the LOM-X722 NIC.

      Minimum Hardware Specifications

      Table 2 lists the minimum hardware specifications supported by openEuler.

      Hard disk≥ 32 GB (120 GB or higher recommended for better user experience)

      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.
