Purchasing and Logging In to a Linux ECS

1. Log in to the management console. In the service list, click Elastic Cloud Server under Compute.

2. Click Buy ECS.

Set Billing Mode and Type.

In this example, the billing mode is Pay-per-use, and the ECS type is General computing. This type of ECS provides a balance of computing, storage, and network resources and applies to most application scenarios.

Set Image and Disk.

1. An image is an ECS template that contains an OS and applications. In this example, a Linux public image is selected, which is provided by HUAWEI CLOUD by default.

2. Retain the default value for the system disk. Click Add Data Disk to add a 100 GB high I/O data disk.

• Select Encryption for the disk to improve disk data security. If the image is not encrypted, the system disk is not encrypted and Unencrypted is displayed on the page for the disk. To obtain more information about disk encryption, click here.
• You can select Share for your disk. Then, your disk can be attached to multiple ECSs. To obtain more information about shareable disks, click here.

1. If you do not have a VPC configured when creating your first ECS, the system automatically creates a default VPC and security group. For more details, click here.

2. If you need to access the Internet, bind an EIP to your ECS. Click Automatically assign. The system automatically assigns an EIP to your ECS.

After creating the ECS, log in to it using a key pair or password.

In this example, a key pair is used for authentication.

1. Select Key pair for Login Mode and click Create Key Pair.

2. In the displayed dialog box, set the key pair name and click OK.

Securely keep the downloaded private key file, which will be used in ECS logins, OS reinstallation, or OS changing.

1. In the Current Configuration area on the right side of the page, click Next. 

2. Verify the order, agree to the service agreement, and click Submit.

3. After you pay for the order, the system automatically creates the ECS for you. It takes several minutes to complete the creation.

1. Switch to the Elastic Cloud Server.

2. View the newly purchased ECS.

3. Select the ECS.

When you are required to log in to the Linux ECS using an SSH key, the ECS must have an EIP bound. Perform the following operations if your ECS has not had an EIP bound during ECS purchasing:

1. Click the name of the target ECS. On the EIPs page, click Bind EIP.
2. Select the primary NIC and an EIP, and click OK.

If no EIP is available, click View EIP and then Buy EIP.

When you use PuTTY to log in to your ECS, your private key file must be in .ppk format. However, the private key file of a key pair created on HUAWEI CLOUD is in .pem format by default. Therefore, before using PuTTY for login, perform the following operations:

1. Run PuTTYgen.

To download PuTTYgen and PuTTY, click here.

2. Click Load and import the private key file.

Ensure that the format of All files (*.*) is selected.

3. Click Save private key.

Save the converted private key file, for example, kp-123.ppk, to the local computer.

1. Double-click EXE.

2. Choose Connection > Data. Enter image username root in Auto-login username.

3. Choose Connection > SSH > Auth. In the last configuration item Private key file for authentication, click Browse and select the private key file in .ppk format.

4. Click Session and enter the EIP bound to the ECS under Host Name (or IP address).

5. Click Open to log in to the ECS.
