Enabling or Disabling Access Control

If load balancing is enabled for a proxy instance, the security group associated with the proxy instance does not apply. You need to use access control to limit access from specific IP addresses.

If access control is not displayed on the management console, the security group associated with the proxy instance is used.

Enabling Access Control

  1. Log in to the management console.
  2. Click in the upper left corner and select a region and a project.
  3. Click in the upper left corner of the page, choose Databases > GaussDB(for MySQL).
  4. On the Instances page, click the instance name to go to the Basic Information page.
  5. In the navigation pane on the left, choose Database Proxy and click the name of a proxy instance to go to the Basic Information page.
  6. Click next to Access Control.
  7. Click Configure. In the displayed dialog box, configure required parameters.

    • Access Control: The blocklist and allowlist cannot be configured at the same time. If you switch between lists, your previously entered settings will be lost. IP addresses or CIDR blocks in the blocklist are not allowed to access the proxy instance.
    • IP Address or CIDR Block: Enter valid IP addresses or CIDR blocks that meet the following requirements:
      • Each line contains an IP address or a CIDR block and ends with a line break.
      • Each IP address or CIDR block can include a description separated by a vertical bar symbol (|), for example, 192.168.10.10|GaussDBforMySQL01. The description can include up to 50 characters but cannot contain angle brackets (<>).
      • Up to 300 IP addresses or CIDR blocks can be added.
