Creating an ECS

Scenarios

This section shows how to create an ECS. In this example, one ECS needs to be created. For details about the ECS parameter configurations, see Resource Planning.

Procedure

  1. Log in to the management console.
  2. Under Computing, click Elastic Cloud Server.

    The Elastic Cloud Server page is displayed.

  3. Click Buy ECS.

    For details, see the Elastic Cloud Server User Guide.

    Configure the following parameters as planned:
    • Image: Select CentOS 7.4 64bit.
    • EIP: An EIP is mandatory if the ECS needs to access the public network. In this example, the multiple devices admin (mdadm) tool needs to be installed. Therefore, an EIP must be configured. Buy an EIP or configure an existing one based on the environment condition.
      Figure 1 shows how to buy a new EIP.
