Purchasing and Logging In to a Linux BMS (New)

Scenario

Bare Metal Server (BMS) combines the scalability of Elastic Cloud Server (ECS) with the high performance of physical servers. It provides dedicated servers on the cloud. You only need to specify a flavor, an image, and network settings, and a BMS will be provisioned to you within 30 minutes.

This section describes how to quickly purchase and use a BMS.

  • Quantity: 1
  • Billing: yearly/monthly (pay-per-use is not available for BMS)
  • Flavor: physical.s4.xlarge
  • OS: Linux
  • Login mode: password

Preparations

  1. Sign up with Huawei Cloud and complete real-name authentication.

    Before purchasing a BMS, sign up for a HUAWEI ID and enable Huawei Cloud services and complete real-name authentication first.

    If you already have enabled Huawei Cloud services and completed real-name authentication, skip this step.

  2. Make sure you have a valid payment method configured.

    If you have a top-up account, you can top up your account.

  3. Plan network resources, such as VPCs and subnets.

    When you are purchasing a BMS, the system creates a default VPC (vpc-default) and subnet (subnet-default).

    If you do not want to use the default VPC and subnet, you can create a VPC and subnet in the region where your BMS will be created. For details, see VPC and Subnet Planning.

  4. Create a security group and add rules.

    When you start to purchase a BMS, the system automatically creates a security group. The default security group allows all outgoing data packets and denies all incoming data packets. This can ensure security of basic BMS communications.

    If the default security group cannot meet your service requirements, you can modify its rules as needed. For details, see Adding a Security Group Rule.

Purchasing a BMS

The following is an example for your reference. For more details, see Creating a Common BMS.

  1. Log in to the management console and go to Buy BMS.
  2. Configure basic settings.
    Figure 1 Basic settings
    Table 1 Basic settings

    Parameter

    Example Value

    Description

    Region

    CN-Hong Kong

    For lower network latency and faster resource access, select the region nearest to your target users. After a BMS is purchased, the region cannot be changed.

    For details, see Region and AZ.

    AZ

    AZ1

    An AZ is a physical location that uses an independent power supply and network. AZs in the same region can communicate with each other over an intranet. The AZ of a purchased BMS cannot be changed.

    Flavor

    physical.s4.xlarge

    Select a flavor based on service requirements. For more information, see Instance Family.

    Image

    CentOS 7.9 64bit

    The example is a free public Linux image provided by Huawei Cloud.

    Disk

    General Purpose SSD, 150 GiB

    A BMS comes with a system disk when you buy it, and the system disk is automatically initialized. You can manually add data disks.

    For details, see EVS Disk.
  3. Configure the network.
    Figure 2 Network parameters
    Table 2 Network parameters

    Parameter

    Example Value

    Description

    Network

    vpc-default-smb

    Use the default VPC and subnet.

    For details, see VPC and Subnet Planning.

    Security Group

    default

    Use the default security group.

    For more information, see Adding a Security Group Rule.

    EIP

    Use existing

    Select an EIP from the drop-down list. If there is no EIP available in the drop-down list, click View EIPs to go to the EIP console. Click Buy EIP and configure parameters by referring to Assigning an EIP.

    For more information, see EIP.
  4. Configure advanced settings.
    Figure 3 Advanced settings
    Table 3 Advanced settings

    Parameter

    Example Value

    Description

    BMS Name

    bms-9493

    Specify a BMS name.

    Login Mode

    Password

    Set a strong password for login.

    Enterprise Project

    default

    This parameter is available only when you use an enterprise account to purchase a BMS.

    You can manage cloud resources by project.
  5. Configure the quantity.
    Figure 4 Parameter settings
    Table 4 Parameters

    Parameter

    Example Value

    Description

    Required Duration

    1

    The duration ranges from one month to one year.

    Quantity

    1

    If you selected Use existing for EIP, you can create only one BMS at a time.
  6. Read and select the agreement, and click Submit.

Logging In to a BMS

If you are using a Windows PC locally, you can log in to a Linux BMS using PuTTY.

For more login methods, see Logging In to a Linux BMS.

You can download PuTTY from https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html.

  1. Run PuTTY.
  2. In the navigation pane on the left, choose Session. Enter the EIP of the BMS in the text box under Host Name (or IP address). Select SSH for Connection type.
  3. In the navigation pane, choose Windows > Translation. Select UTF-8 from the Received data assumed to be in which character set: drop-down list.
  4. Click Open.
  5. Enter username root and the password you set to log in to the BMS.
