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:
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.
