Public Cloud Image User Guide ​

Multiple public cloud vendors are providing openEuler cloud images. This document takes Huawei Cloud as an example to introduce how to use openEuler images. The usage of openEuler on other clouds is similar to that on Huawei Cloud, and the detailed usage methods can be found in the user guides of the respective cloud products.

Available Versions ​

The following openEuler image versions have been released on mainstream public clouds:

• AWS Marketplace

• Huawei Cloud KooGallery

Note: Tencent Cloud has not yet widely adopted Arm computing power, and many regions in China are not available during release. Therefore, the openEuler image for AArch64 has not been released on Tencent Cloud.

openEuler Cloud Instance Creation ​

This section takes cloud host (instance) creation on Huawei Cloud as an example to illustrate how to use openEuler on a public cloud.

1. Log in to the HUAWEI CLOUD website and click Console.

   

2. Select Elastic Cloud Server.

   

3. Buy and configure an ECS.

   

   1. Configure computing resources.

   2. Select an openEuler image.

   3. Configure the network.

   4. Configure the login mode. Huawei Cloud KooGallery requires released images to prohibit root user login. Therefore, the root user can only log in through the console. If you need to use the root user, log in through the console and modify the /etc/ssh/sshd_config file.

   5. Completing the purchase.

   6. Log in and use the ECS.

      After the status of the created ECS changes to Running, you can remotely log in to the ECS.

      Due to the image release requirements of Huawei Cloud KooGallery, ECSs running openEuler images cannot be accessed via root login or password authentication. The default user is openeuler. Therefore, before using the ECS, you need to log in to the console as the root user set in step 4 and modify the configuration items in the /etc/ssh/sshd_config file as follows:

      shell

      # /etc/ssh/sshd_config
      
      # Allows root user login.
      PermitRootLogin yes
      # Allows password authentication.
      PasswordAuthentication yes

      After the modification, you can log in as the root user from any terminal through SSH.

      shell

      $ ssh root@1.92.159.107
      
      Authorized users only. All activities may be monitored and reported.
      root@1.92.159.107's password:
      
      Authorized users only. All activities may be monitored and reported.

The method of using openEuler images on other clouds is similar to that on Huawei Cloud. For details, see the user guide of the respective cloud product.

Obtaining the openEuler Shared Image on Azure ​

1. Log in to the Azure Portal.

2. Go to the account home page and search for "Community images."

   

3. On the Community images page, search for the "openEuler" to view available openEuler images.

   

4. Click the target image and create a VM.
