ApsaraDB for OceanBase (Deprecated):Add a whitelist group for a cluster instance

Background

• ApsaraDB for OceanBase allows you to add whitelist groups for cluster instances. Each cluster instance has a default whitelist group that cannot be deleted. When you connect to a cluster instance for the first time, you must first configure an IP address whitelist for the cluster instance.

• You can add a maximum of 10 whitelist groups for a cluster instance. Each whitelist group must have a unique name and cannot be empty. Each whitelist group supports a maximum of 40 whitelists.

• Whitelist groups ensure access security for cluster instances. We recommend that you maintain whitelist groups regularly.

Procedure

1. In the left-side navigation pane, click Instances and select the target cluster instance to go to the Cluster Instance Workspace page.

2. In the left-side navigation pane, click Security Settings.

3. On the Whitelist tab, click Add Whitelist Group.

4. Specify Group Name and IP Address.

   Parameter	Description
   Group Name	The whitelist group name must be 2 to 32 characters in length, start with a lowercase letter, end with a lowercase letter or digit, and contain only lowercase letters, digits, and underscores (_).
   IP Address	You can enter an IP address, for example, 192.168.0.1, or a CIDR block, for example, 192.168.0.0/24. Separate multiple IP addresses with commas (,), for example, 192.168.0.1,192.168.0.0/24. 127.0.0.1 indicates that no access from any IP address is allowed. 0.0.0.0 indicates that access from all IP addresses is allowed. Changes to the whitelist of the cluster instance take effect for all tenants. Each whitelist group supports a maximum of 40 whitelists.

5. Click OK.

6. After a whitelist is added, click the Edit icon next to the whitelist group to add or remove whitelists. Click the Copy icon to copy an existing whitelist.
