You can configure whitelists for your PolarDB-X instance. Whitelists do not affect the performance of the PolarDB-X instance in a negative manner. We recommend that you manage the whitelists of your database instance on a regular basis. This can help ensure that the data on your PolarDB-X instance is secure. This topic describes how to configure a whitelist for your PolarDB-X instance.

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.

Add a whitelist

  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 left-side navigation pane, choose Configuration and Management > Safety management.
  6. On the Whitelist settings tab, click Add whitelist grouping.
  7. In the Add whitelist grouping panel, configure the parameters.
    Parameter Description
    Group name Specify a name for the whitelist.
    Whitelist in group 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.
  8. Click OK.
    Note The whitelist takes effect approximately 1 minute after it is created.
