This section describes the compatibility of the hardware and software and the related configurations and preparations required for the installation.
- Installation Preparations
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:
Log in to the openEuler Community website.
Click the link provided after Download ISO. The download list is displayed.
Click openEuler-20.03-LTS. The openEuler 20.03 LTS version download list is displayed.
Click ISO. The ISO 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
Select the openEuler release package and verification file to be downloaded based on the architecture of the environment to be installed.
If the AArch64 architecture is used:
- Click aarch64.
- Click openEuler-20.03-LTS-aarch64-dvd.iso to download the openEuler release package to the local host.
- Click openEuler-20.03-LTS-aarch64-dvd.iso.sha256sum to download the openEuler verification file to the local host.
If the x86_64 architecture is used:
- Click x86_64.
- Click openEuler-20.03-LTS-x86_64-dvd.iso to download the openEuler release package to the local host.
- Click openEuler-20.03-LTS-x86_64-dvd.iso.sha256sum to download the openEuler verification file to the local host.
Release Package Integrity Check
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.
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.
Before verifying the integrity of the release package, you need to prepare the following files:
ISO file: openEuler-20.03-LTS-aarch64-dvd.iso
Verification file: openEuler-20.03-LTS-aarch64-dvd.iso.sha256sum
To verify the file integrity, perform the following operations:
Obtain the verification value in the verification file. Run the following command:
$ cat openEuler-20.03-LTS-aarch64-dvd.iso.sha256sum
Calculate the SHA256 verification value of the file. Run the following command:
$ sha256sum openEuler-20.03-LTS-aarch64-dvd.iso
After the command is run, the verification value is displayed.
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.
You need to take hardware compatibility into account during openEuler installation. Table 1 describes the types of supported servers.
- 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
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 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.
