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 Download > Software Packages.
3. Click Server Image below openEuler 22.03 LTS SP1. The ISO list is displayed.
   • aarch64: ISO image files of the AArch64 architecture
   • x86_64: ISO image files of the x86_64 architecture
   • source: ISO image files of the openEuler source code
4. Select the target openEuler release package and verification file based on the actual environment.

   • AArch64 architecture:

     1. Click aarch64.
     2. If you install openEuler from a local source, download the release package openEuler-22.03-LTS-SP1-aarch64-dvd.iso and the verification file openEuler-22.03-LTS-SP1-aarch64-dvd.iso.sha256sum to the local host.
     3. If you install openEuler through the network, download the release package openEuler-22.03-LTS-SP1-netinst-aarch64-dvd.iso and the verification file openEuler-22.03-LTS-SP1-netinst-aarch64-dvd.iso.sha256sum to the local host.

   • x86_64 architecture:

     1. Click x86_64.
   1. If you install openEuler from a local source, download the release package openEuler-22.03-LTS-SP1-x86_64-dvd.iso and the verification file openEuler-22.03-LTS-SP1-x86_64-dvd.iso.sha256sum to the local host.
      1. If you install openEuler through the network, download the release package openEuler-22.03-LTS-SP1-netinst-x86_64-dvd.iso and the verification file openEuler-22.03-LTS-SP1-netinst-x86_64-dvd.iso.sha256sum 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 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 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-SP1-aarch64-dvd.iso

Verification file: openEuler-22.03-LTS-SP1-aarch64-dvd.iso.sha256sum

Procedures

To verify the file integrity, perform the following operations:

1. Obtain the verification value in the verification file. Run the following command:

   $ cat openEuler-22.03-LTS-SP1-aarch64-dvd.iso.sha256sum 
   

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

   $ sha256sum openEuler-22.03-LTS-SP1-aarch64-dvd.iso
   

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

3. 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 before installing openEuler. Table 1 describes supported servers.

NOTE:

• TaiShan 200 servers are based on 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

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 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 3 lists the minimum virtualization platform specifications supported by openEuler.
