PolarDB:Configure a security group

Scenario

Precautions

• The network types of a PolarDB for MySQL cluster and the security groups that are added to its whitelist must be the same. For example, if your PolarDB for MySQL cluster is deployed in a virtual private cloud (VPC), you can add only security groups of the VPC type.

• You can add up to 10 security groups to a PolarDB for MySQL cluster.

• When a security group is added to a PolarDB for MySQL cluster, the IP addresses of the ECS instances in the security group are added to the whitelist of the cluster. The security group rules do not affect this operation.

Procedure

1. Log on to the PolarDB console.

2. In the left-side navigation pane, click Clusters.

3. In the upper-left corner, select the region where the cluster to which you want to connect is deployed.

4. Find the cluster and click its ID.

5. In the left-side navigation pane, choose Settings and Management > Cluster Whitelists.

6. On the Cluster Whitelists page, you can click Select Security Group to add a security group. You can also click Configure in the Actions column to change the security groups.

   

7. In the Select Security Groups panel, select one or more security groups and click OK.
