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. Log in to the openEuler Community website.
  2. Click Download.
  3. Choose the card openEuler-20.03-LTS-SP1. Click the link provided after Download ISO.The download list is displayed.
    • aarch64: ISO image file of the AArch64 architecture
    • x86_64: ISO image file of the x86_64 architecture
    • source: ISO image file of the openEuler source code
  4. Select the openEuler release package and verification file to be downloaded that adapt to the architecture of the environment to be installed.
    • AArch64 architecture:

      1. Click aarch64.
      2. If you install the environment on the local host, download the release package openEuler-20.03-LTS-SP1-aarch64-dvd.iso and the verification file openEuler-20.03-LTS-SP1-aarch64-dvd.iso.sha256sum to the local host.
      3. If you install the environment on the network, download the release package openEuler-20.03-LTS-SP1-netinst-aarch64-dvd.iso and the verification file openEuler-20.03-LTS-SP1-netinst-aarch64-dvd.iso.sha256sum to the local host.
    • x86_64 architecture:

      1. Click x86_64.
      2. If you install the environment on the local host, download the release package openEuler-20.03-LTS-SP1-x86_64-dvd.iso and the verification file openEuler-20.03-LTS-SP1-x86_64-dvd.iso.sha256sum to the local host.
      3. If you install the environment on the network, download the release package openEuler-20.03-LTS-SP1-netinst-x86_64-dvd.iso and the verification file openEuler-20.03-LTS-SP1-netinst-x86_64-dvd.iso.sha256sum to the local host.

Note
When the network is available, install the environment on the network because the ISO release package is small.

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-SP1-aarch64-dvd.iso

Verification file: openEuler-20.03-LTS-SP1-aarch64-dvd.iso.sha256sum

Procedure

To verify the file integrity, perform the following operations:

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

    $ cat openEuler-20.03-LTS-SP1-aarch64-dvd.iso.sha256sum 
    
  2. Calculate the SHA256 verification value of the file. Run the following command:

    $ sha256sum openEuler-20.03-LTS-SP1-aarch64-dvd.iso
    

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

  3. Check whether the values calculated in step 1 and step 2 are consistent.

    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.

Table 1 Supported servers

Server Type Server Name Server Model
Rack server TaiShan 200 2280 balanced model
Rack server FusionServer Pro FusionServer 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.

Table 2 Minimum hardware specifications

Component Minimum Hardware Specifications
Architecture AArch64 or x86_64
CPU Two CPUs
Memory ≥ 4 GB (8 GB or higher recommended for better user experience)
Hard disk ≥ 120 GB (for better user experience)

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

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.
