Step 1: Starting Preparations

This guide is an introductory tutorial that demonstrates how to create a sample GaussDB(DWS) cluster, connect to the cluster database, import the sample data from OBS, and analyze the sample data. You can use this tutorial to evaluate GaussDB(DWS).

Before creating a GaussDB(DWS) cluster, ensure that the following prerequisites are met:

Registering a Public Cloud Account

If you do not have a public cloud account, register one.

  1. Open the official public cloud website (https://www.huaweicloud.com/eu/) and click Register in the upper right corner. The registration page is displayed.
  2. Fill in user information as instructed to complete the registration.
  3. After the registration is successful, you can be automatically logged in to Huawei Cloud.

Determining the Cluster Ports

  • When creating a GaussDB(DWS) cluster, you need to specify a port for SQL clients or applications to access the cluster.
  • If your client is behind a firewall, you need an available port so that you can connect to the cluster and perform query and analysis from the SQL client tool.
  • If you do not know an available port, contact the network administrator to specify an open port on your firewall. The ports supported by GaussDB(DWS) range from 8000 to 30000.
  • After a cluster is created, its port number cannot be changed. Ensure that the port specified is available.
