Create a cluster

You can create a cluster as needed.

Prerequisite

You have the permission to create a cluster.

Procedure

1. Log on to the OceanBase Cloud Platform (OCP) console, and find the entry to cluster creation based on the actual business scenario.

   • If you do not have a manageable cluster, the system displays a message on the Clusters page prompting you to create one. Click Create Cluster in the prompt.

   • If you already have a manageable cluster, go to the Clusters page, and click Create Cluster in the upper-right corner.

2. On the Create Cluster page, set the basic information of the cluster.

   • Create a primary cluster

     

     The following table describes the fields of basic information.

     Parameter	Description
     Cluster Type	Select Primary Cluster .
     Cluster Name	Specifies the name of the cluster to be created. The cluster name must start with a letter and consist of 2 to 48 characters, including uppercase and lowercase letters, digits, and underscores (_).
     root@sys Password	This parameter can be customized or randomly generated. The password must meet the following complexity conditions: Be 8 to 32 characters in length. It contains at least three of the following character types: digits(0~9), uppercase letters(A~Z), lowercase letters(a~z), and special characters (ie: ~!@#%^&*_-+=|(){}[]:;,.?/).
     OceanBase Version	Specifies the OceanBase Database version. You can select a version from the drop-down list, or click Add Version at the bottom of the list to upload a version.
     Associate OBProxy Cluster	Allows you to associate the cluster with an OBProxy cluster. Turn on the switch and select an existing OBProxy cluster to associate it with the cluster.

   • Create a standby cluster

     

     The following table describes the fields of basic information.

     | Parameter | Description | |-----------------------------------------|--| | Cluster Type | Select Standby . Make sure that the primary cluster is created. | | OCP to Which Leader Cluster Belongs | You must specify this field in multi-cluster mode. For more information, see OCP multi-cluster mode. | | Primary Cluster | Select the primary cluster and the system will create a standby cluster of the selected primary cluster. | | root@sys Password | You must specify this field in multi-cluster mode. Enter the root@sys password for the primary cluster. After the task is submitted, the password is saved in the password box. | | Standby Cluster OceanBase Version | Select an OceanBase Version that is the same as the primary cluster.

     • If the version exists in the drop-down list, select it.
     • Otherwise, click Add Version at the bottom of the list to upload the version.

3. Set the deployment mode of the cluster.

   

   By default, three zones are added for a cluster. To deploy more than three zones for the cluster, click Add . To deploy less than three zones for the cluster, click the delete icon after the zone to be deleted. The following table describes the settings for each zone.

   Parameter	Description
   Zone Name	You can retain the default name or define a custom name. A zone name must consist of 2 to 48 characters, including uppercase and lowercase letters, digits, and underscores (_), and start with a letter.
   IDC	The IDC of the zone. Each zone can be deployed in only one IDC.
   Host Type	Optional. If you select a host type, the host list is filtered based on the host type.
   Server Selection Method	Choose Automatic or Manual .
   IP	You can select multiple IP addresses. If Server Selection Method is Automatic , you only need to enter the number of servers. If Server Selection Method is Manual , you need to manually select several IP addresses from the list.
   Root Server	You can select an IP address for the Root Server.
   Zone Priority Rankings (This field is not required when creating a standby cluster)	Specifies the priorities of the zones. The priority order affects the priority order of the Primary Zone of the sys tenant. Ranking method: 1. Select one or more zones from the left-side list. The left-side list shows all zones available in the cluster. 2. Click the closing angle bracket (>) in the middle. The selected zones are moved to the Priority Rankings list. The zones that are selected at the same time have the same priority. 3. Repeat steps a and b to add zones of lower priority. 4. To adjust the priority, drag the target zone in the Priority Rankings list, and reorder it. The priority in the list decreases from top to bottom.
