Bind or unbind clusters

You must bind a dns cluster to a Simple Log Service cluster to collect resolution logs, generate visual reports, and trigger alert notifications.

  • dns cluster: A cluster that consists of a management agent service and DNS service nodes.

  • Simple Log Service cluster: A cluster that collects resolution logs and alert information from DNS service nodes in the bound dns cluster.

Bind a dns cluster

Procedure

  1. Go to the Alibaba Cloud DNS - On-premises DNS console.

  2. Click the bind icon next to All Clusters.image

  3. In the Cluster Settings dialog box, select the dns clusters to bind, and then click OK.

  4. Once the binding is complete, the Service Status for the DNS and management agent services in the corresponding dns cluster changes from Unbound to Available.

Unbind a dns cluster

Procedure

  1. Go to the Alibaba Cloud DNS - On-premises DNS console.

  2. Click the bind icon next to All Clusters.image

  3. In the Cluster Settings dialog box, remove the dns clusters you want to unbind, and then click OK.

  4. Once the unbinding is complete, the Service Status for the DNS and management agent services in the corresponding dns cluster changes from Available to Unbound.

Manage clusters

Add a cluster

  • If your business spans multiple regions, you can add multiple dns clusters to deploy DNS services in each region.

  • You cannot add Simple Log Service clusters. You can only modify them.

Procedure

  1. Go to the Alibaba Cloud DNS - On-premises DNS console.

  2. Click the add icon next to All Clusters.image

  3. In the Add a DNS Cluster dialog box, enter a Cluster Name and click OK to add the dns cluster to the list.

Delete a cluster

  • You can only delete dns clusters. You cannot delete Simple Log Service clusters, but you can modify them.

  • You cannot delete the default dns cluster created by the system. The system identifies this cluster by its internal ID, so renaming it does not allow deletion.

Procedure

  1. Go to the Alibaba Cloud DNS - On-premises DNS console.

  2. Click the delete icon next to the dns cluster.

  3. In the Reminder of Deleting a Cluster prompt, click OK to delete the cluster.

    Warning

    Before you delete a dns cluster, you must remove all its nodes.

    • When you remove the last node from a dns cluster, the system automatically disassociates all domain names from that cluster.

    • Deleting a dns cluster also unbinds it from the O&M cluster.

Modify a cluster

You can rename any cluster for easier identification and management.

Procedure

  1. Go to the Alibaba Cloud DNS - On-premises DNS console.

  2. Click the edit icon next to the cluster.

  3. In the dialog box that appears, enter a new name and click OK to save the change.
