By default, a PolarDB-X instance is assigned a private endpoint when the instance is created. You can use the private endpoint to connect your applications and MySQL clients on Alibaba Cloud Elastic Compute Service (ECS) instances to databases on the PolarDB-X instance. If you need to access the PolarDB-X instance over the Internet, you must apply for a public endpoint for the PolarDB-X instance. This topic describes how to apply for and release a public endpoint.

Apply for a public endpoint

  1. Log on to the PolarDB-X console.
  2. In the top navigation bar, select the region where the target instance is located.
  3. On the Instance List page, click the PolarDB-X 2.0 tab.
  4. Find the target instance and click its ID.
  5. In the Connection information section of the Basic information page, click Apply for external network address in the upper-right corner.

  6. In the message that appears, click OK.
    Note If you want to connect to the PolarDB-X instance by using the public endpoint, you must add the public IP address of your client to a whitelist of the instance. For more information, see Configure whitelists.

Release a public endpoint

  1. Log on to the PolarDB-X console.
  2. In the top navigation bar, select the region where the target instance is located.
  3. On the Instance List page, click the PolarDB-X 2.0 tab.
  4. Find the target instance and click its ID.
  5. In the Connection information section of the Basic information page, click Release the external network address in the upper-right corner.

  6. In the message that appears, click OK.
    Note After you release the public endpoint, you cannot use the public endpoint to connect to the instance. After the public endpoint is released, we recommend that you remove the corresponding public IP address from the whitelist to ensure data security. For more information, see Configure whitelists.
