Add a binlog node

You can add binlog nodes to a binlog cluster to scale out the cluster.

In OceanBase Cloud Platform (OCP), you can add a binlog node by using either of the following methods:

• Method 1: On the Cluster List page, click New Node in the Actions column of the target cluster.
• Method 2: On the Binlog Cluster Overview tab, click New Node in the upper-right corner.

Prerequisites

Make sure that you have the following permissions:

• Resource Permissions: Binlog Service Maintenance permission
• Menu Permissions: Permission on the Binlog Cluster Overview menu of the Binlog Service

Procedure

The following procedure describes how to add a binlog node by using Method 2.

1. Log on to the OCP console.

2. In the left-side navigation pane, click Binlog Service. The Cluster List tab automatically appears.

3. On the Cluster List page, find the target binlog cluster and click its name.

4. On the Binlog Cluster Overview tab, click New Node in the upper-right corner.

5. In the New Node dialog box, specify the IDC, model, and host of the binlog node to be added. You can select multiple hosts.

   By default, only one binlog node is added. To add more binlog nodes, click New Binlog Server.

6. Click OK to submit the task to add a binlog node.

   You can view the task progress in Task Center. When the task enters the ExecuteSuccessful state and the status of the corresponding binlog node is displayed as Normal Operation in the Binlog Server List section on the Binlog Cluster Overview page, the binlog node is successfully added.
