ApsaraDB RDS:Configure database proxy endpoints

Prerequisites

The database proxy service is enabled. For more information, see Enable the database proxy.

Usage notes

• A single RDS for PostgreSQL instance supports 1 to 7 proxy endpoints. For each proxy endpoint, you can apply for one private address in a Virtual Private Cloud (VPC) and one public endpoint.

• When you enable the database proxy, the service creates one default proxy endpoint. This default endpoint cannot be deleted.

• When you add a new proxy endpoint, the service automatically creates a private address for it in the Virtual Private Cloud (VPC). This private address cannot be deleted.

Add a proxy endpoint

1. Go to the Instances page. In the top navigation bar, select the region in which the RDS instance resides. Then, find the RDS instance and click the ID of the instance.

2. In the left-side navigation pane, click Database Proxy.

3. In the Connection Information section, click Create Proxy Endpoint.

4. In the dialog box, configure an access policy for the proxy endpoint.

   Note

   For more information about proxy endpoint access policies, see Configure an access policy for a database proxy endpoint.

5. Click OK.

Modify a proxy endpoint and port

1. Go to the Instances page. In the top navigation bar, select the region in which the RDS instance resides. Then, find the RDS instance and click the ID of the instance.

2. In the left-side navigation pane, click Database Proxy.

3. In the Connection Information section, find the target proxy endpoint and click the icon next to the endpoint.

4. In the dialog box, set the Endpoint and Port, and then click OK.

   Note

   • Port range: 1000 to 5999.

   • You cannot modify the address type.

Apply for or release a public endpoint

1. Go to the Instances page. In the top navigation bar, select the region in which the RDS instance resides. Then, find the RDS instance and click the ID of the instance.

2. In the left-side navigation pane, click Database Proxy.

3. In the connection information section, find the target proxy endpoint and click Public Endpoint/Port or Release Public Endpoint in the Apply for Public Endpoint column.

   If you click Apply for Public Endpoint, set the address prefix and Port for the public endpoint in the dialog box, and then click OK.

   Note
