Deploy OCP on the GUI

This topic describes how to deploy OceanBase Cloud Platform (OCP) Community Edition on the GUI of OceanBase Deployer (OBD).

As an essential part of OCP, MetaDB stores metadata and monitoring data that is managed by OCP. OCP-Server manages an OceanBase cluster throughout its entire lifecycle by calling the data stored in MetaDB. You can use either of the following methods to deploy OCP:

• (Recommended) Create an OceanBase cluster as the MetaDB of OCP.

• Use an existing OceanBase cluster as the MetaDB of OCP.

Prerequisites

• You can deploy only OCP Community Edition V4.0.3 or later.

• You have installed and configured a Java environment by using JDK 1.8, and the build version is at least 161.

• You have renamed or deleted the directory where the OCP software package of the earlier version is decompressed on the OCP host. This is to avoid confusion with the decompression directory of the new version.

• You have obtained and uploaded the ocp-all-in-one-4.3.5-YYYYMMDDhhmmss.el7.x86_64.tar.gz software package to a directory on the OCP host, and decompressed the package by running the following command. For more information, see Prepare for the installation.

  tar zxf ocp-all-in-one-4.3.5-YYYYMMDDhhmmss.el7.x86_64.tar.gz
  

(Recommended) Create an OceanBase cluster as the MetaDB of OCP

Step 1: Start OBD

1. Log on to the OCP host.

2. Run the following command to go to the bin directory of the decompressed software package, and start the installer:

   cd ocp-all-in-one/bin && bash install.sh
   

3. Run the following command to make the environment variables take effect:

   source ~/.oceanbase-all-in-one/bin/env.sh
   

4. Run the obd web install command, and copy the IP address of the deployment wizard page in the response.

Step 2: Go to the OCP deployment wizard page

1. Open a browser, visit the IP address copied in Step 1 , and click Try Now on the page that appears.

2. Select OCP and click OK .

3. Select Create a new OceanBase database MetaDB as OCP and click OK .

Step 3: Specify the deployment information

1. Specify the name of the OceanBase cluster to be managed.

   The cluster name must be unique. It must start with a letter and end with a letter or digit, and must be 2 to 32 characters in length.

2. Select the versions of services to be deployed.

   The supported version of OBProxy depends on that of OceanBase Database. For example, if you deploy OceanBase Database V4.1.0 or later, you can deploy only OBProxy V4.1.0 or later.

Step 4: Configure MetaDB

After you create a local MetaDB, OCP-Server uses it to achieve higher service reliability.

1. Set parameters of the deployment user.

   Note

   To avoid conflicts between OS users, we recommend that you create dedicated OS users for MetaDB and OCP.

   Parameter	Description
   Username	The username of the OS user of the host, who has permissions to run sudo commands. The installer requires this username to automatically complete the settings.
   Password	The password of the user. If you have enabled password-free logon for the host, skip this parameter.
   SSH Port	The SSH port number of the host. Default value: 22. You can specify a custom port number.
   Use the running user	If you select this parameter, you can specify a dedicated OS user for OCP. This parameter is optional.

2. Set parameters of the OCP node.

   Select the host where you want to deploy OCP. You can select multiple hosts.

   Notice

   The IP address of the host cannot be 127.0.0.1.

3. Set parameters of database nodes.

   Parameter	Description
   Zone Name	You can retain the default name or define a custom name. The zone name must start with a letter and end with a letter or digit, and must be 2 to 32 characters in length. In an OceanBase cluster that consists of multiple zones, the cluster must have a zone that shares the same region as that of the primary zone.
   OBServer Node	Select the OBServer node where you want to deploy MetaDB. You can select multiple OBServer nodes.
   RootServer Node	You can select an IP address as the host for RootService. In an OceanBase cluster that has multiple replicas, you must specify a RootServer node for each zone.

   By default, only one zone is added. You can click Add to add more zones. To delete a zone, click the Delete icon after the zone to be deleted.

4. Set cluster parameters.

   Parameter	Description

2. Allocate resources.

   OCP consumes large amounts of computing and storage resources to provide services. You can allocate resources based on the number of hosts to be managed. In addition, you must set parameters in the MetaDB Tenant and MonitorDB Tenant sections. This way, the system automatically creates a MetaDB tenant and a MonitorDB tenant to manage the OceanBase cluster throughout its entire lifecycle.

   1. Specify the number of hosts to be managed.

      The default value is 10. You can change the value as needed.

   2. Specify the memory size.

      By default, 16 GiB of memory is allocated. You must allocate memory resources based on the number of hosts managed by OCP. For more information, see Host planning.

   3. Set parameters of the MetaDB tenant.

      Parameter	Description
      Tenant Name	The name of the MetaDB tenant. Default value: ocp_ meta. You can specify a custom tenant name.

The custom password must meet the following complexity requirements: It must be 8 to 32 characters in length. It must contain characters of at least three of the following types: digits (0 to 9), uppercase letters (A to Z), lowercase letters (a to z), and special characters. Supported special characters are ~ ! @ # % ^ & * _ - + =	( ) { } [ ] : ; , . ? /.

      Memory	The size of memory allocated to the MonitorDB tenant. Default value: 4 GiB. You can adjust the value as needed.

Step 6: Run an environment precheck

Before you start the precheck, you must verify the configuration information.

• If you find an error, click Previous to fix it.

• After you verify the information, click Pre-check. Then, the system checks whether your environment meets all the requirements for MetaDB and OCP installation and configuration.

  • If the precheck reports an error, you can fix the error based on the solution provided by OCP. If the error can be automatically fixed, you can click Auto repair to fix it.

    After all errors are fixed, click Re-check to perform a precheck again.

  • If the precheck is passed, click Next .

Step 7: Deploy OCP

You can view detailed installation logs in the Deployment Logs section during the OCP deployment process.

• If the deployment fails, check the logs to identify the causes, and contact OceanBase Technical Support. After you identify the causes and fix the issue, click Redeploy. Then, the system clears the failed OCP installation environment and re-executes the installer.

• If the deployment succeeds, click Complete to exit. Before you exit the installer, you can copy the URL, account username, and account password for logging on to the OCP console.

Use an existing OceanBase cluster as the MetaDB of OCP

   Note

   To avoid conflicts between OS users, we recommend that you create dedicated OS users for MetaDB and OCP.

   Parameter	Description
