PolarDB:Configure whitelists

Note

• After you create a database in your PolarDB-X instance, the default whitelist contains only the 127.0.0.1 IP address. In this case, no IP addresses can access the database. To ensure that your data is secure, we recommend that you specify only the public IP addresses or CIDR blocks of your web servers in the whitelists of your instance.

• You can create up to 50 whitelists for a PolarDB-X instance, and each whitelist can contain up to 300 IP addresses and CIDR blocks.

• IPv6 addresses are not supported.

Add a whitelist

1. Log on to the PolarDB-X console.

2. In the top navigation bar, select the region where the instance is deployed.

3. On the Instances page, click the PolarDB-X 2.0 tab.

4. Find the instance that you want to manage and click its ID.

5. In the left-side navigation pane, choose ConfigurationManagement > Safety management.

6. On the Whitelist settings tab, click Add Whitelist.

7. In the Add Whitelist panel, configure the parameters.

   Parameter	Description
   Group Name	Specify a name for the whitelist.
   Group Whitelist	Specify IP addresses. Note You can enter IP addresses and CIDR blocks. For example, you can enter the 192.168.0.1 IP address and the 192.168.0.0/24 CIDR block. You can specify up to 300 IP addresses and CIDR blocks in a whitelist. Separate multiple IP addresses and CIDR blocks with commas (,). For example, you can enter 192.168.0.1,192.168.0.0/24. If you want to block access from all IP addresses, you can specify 127.0.0.1 in the whitelist. Specify an IP address of 0.0.0.0/0 to allow access from all IP addresses. This may cause security risks. Proceed with caution.

8. Click OK.

   Note

   The whitelist takes effect approximately 1 minute after it is created.
