Selecting HCE as the Public Image When Creating an ECS Procedure Log in to the ECS console. Select HCE as the public image. On the Configure Basic Settings page, select Public Image, and select Huawei Cloud EulerOS and an image version.
If you want to change the ECS OS and the software is loosely coupled with the OS, change it. This does not affect the ECS configurations (such as NICs, disks, and VPNs). For details about how to change to Huawei Cloud EulerOS, see Changing an OS to Huawei Cloud EulerOS.
Preparations Prepare an ECS and assign a public IP address or EIP to the ECS. Prerequisites The irqbalance service is disabled.
Why Can't HCE Obtain an IPv6 Address After IPv6 Is Enabled for an ECS? Background After IPv6 is enabled for ECS NICs on the ECS console, HCE cannot obtain an IPv6 address because DHCP is not correctly configured for the OS.
In the Change ECS OS dialog box, confirm the specifications, read and agree to the agreement or disclaimer, and click OK. The ECS status changes to Changing OS. When Changing OS disappears, the change is successful.

Switch back to the ECS console, locate the ECS whose OS is to be changed, and choose More > Manage Image > Change OS in the Operation column. In the Change OS dialog, configure the following parameters: Select Stop the ECS. Image: Select Private image.
If only the ECS OS needs to be changed but the other ECS details (NICs, disks, and VPNs) need to be kept the same, as long as the software is loosely coupled with the OS, you can change the OS to HCE with only a few additional changes needed. Migrate the OS to HCE.
Although the OS is free, when you use an HCE image to create an ECS, you still need to pay for the required resources, such as vCPUs, memory, storage, public IP address, and bandwidth. For details, see Billing.
Using ECS improves the competitiveness of Elastic Cloud Server (ECS), Cloud Container Engine (CCE), Elastic Load Balance (ELB), and database services.
Log in to the ECS using CloudShell.
Faster startup: Only required basic components are loaded to suit specific ECS configurations, so ECS can bootup faster.
Use one ECS as the FTP server and the other as the client. Configure security group inbound rules to allow traffic to the FTP server over port 21. Prerequisites A yum repository has been configured.
Preparations Prepare an ECS and assign a public IP address or EIP to the ECS. Ensure that inbound security group rules allow traffic to flow to the ECS over port 8080. Prerequisites A yum repository has been configured.
Remotely log in to the ECS to be migrated and verify that it can be accessed from the Internet. For details, see Login Overview. Disable all repository configurations in /etc/yum.repos.d of CentOS. This ensures that the repositories of CentOS and HCE do not conflict.
Preparations Prepare an ECS and assign a public IP address or EIP to the ECS. Ensure that inbound security group rules allow traffic to flow to the ECS over port 22. Procedure Configure the SFTP service.
Preparations Prepare an ECS and assign a public IP address or EIP to the ECS. Ensure that inbound security group rules allow traffic to flow to the ECS over port 80. Prerequisites A yum repository has been configured.
Preparations Prepare an ECS and assign a public IP address or EIP to the ECS. Ensure that inbound security group rules allow traffic to flow to the ECS over ports 80, 8001, and 8002. Prerequisites A yum repository has been configured.
Preparations Prepare an ECS and assign a public IP address or EIP to the ECS. Prerequisites A yum repository has been configured. For details about how to configure a yum repository accessed over the Internet, see Configuring Repositories and Installing Software for HCE.
Preparations Prepare an ECS and assign a public IP address or EIP to the ECS. Ensure that inbound security group rules allow traffic to flow to the ECS over port 9092. Prerequisites A yum repository has been configured.
