      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 SP3.
      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. For local installation, download the Offline Standard ISO or Offline Everything ISO release package openEuler-22.03-LTS-SP3-(everything-)aarch64-dvd.iso to the local host.
          3. For network installation, download the Network Install ISO release package openEuler-22.03-LTS-SP3-netinst-aarch64-dvd.iso to the local host.
        2. If the architecture is x86_64:
          1. Click x86_64.
          2. For local installation, download the Offline Standard ISO or Offline Everything ISO release package openEuler-22.03-LTS-SP3-(everything-)x86_64-dvd.iso to the local host.
          3. For network installation, download the Network Install ISO release package openEuler-22.03-LTS-SP3-netinst-x86_64-dvd.iso to the local host.

      Note When the network is available, install openEuler through the network because the ISO release package is small. The release package of AArch64 architecture supports UEFI mode, while the release package of x86_64 architecture supports UEFI mode and Legacy mode.

      Release Package Integrity Check

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

      Introduction

      To check whether the software package is 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 calculated verification value of the ISO file to check whether the software package is complete. 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-22.03-LTS-SP3-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-22.03-LTS-SP3-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 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 before installing openEuler. The Compatibility List describes supported servers.

      Minimum Hardware Specifications

      Table 1 lists the minimum hardware specifications supported by openEuler.

      Table 1 Minimum hardware specifications

      ComponentMinimum Hardware Specifications
      ArchitectureAArch64 or x86_64
      CPUTwo single-core CPUs
      Memory≥ 4 GB (8 GB or higher recommended for better user experience)
      Hard drive≥ 32 GB (120 GB or higher recommended for better user experience)

      Installation Requirements for VMs

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

      Virtualization Platform Compatibility

      You need to take the compatibility of the virtualization platform into account before installing openEuler. Currently, the following virtualization platforms are supported:

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

      Minimum Virtualization Platform Specifications

      Table 2 lists the minimum virtualization platform specifications supported by openEuler.
