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.

Please follow the steps below to obtain the openEuler release package and verification file:

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 SP4.
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-SP4-(everything-)aarch64-dvd.iso to the local host.
      3. For network installation, download the Network Install ISO release package openEuler-22.03-LTS-SP4-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-SP4-(everything-)x86_64-dvd.iso to the local host.
      3. For network installation, download the Network Install ISO release package openEuler-22.03-LTS-SP4-netinst-x86_64-dvd.iso to the local host.

Release Package Integrity Check ​

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-SP4-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:

   sh

   sha256sum openEuler-22.03-LTS-SP4-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 hardware compatibility and minimum hardware 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

Installation Requirements for VMs ​

To install the openEuler OS on a VM, the VM must meet the following hardware compatibility and minimum hardware 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 ​
