This section describes how to use Pulsar. For details, see Pulsar Overview.

By default, all service ports involved in this solution are accessible within the same subnet. You can modify the security group rules if needed. The service ports are as follows:

9527 for the Pulsar manager node
2181, 2888, and 3888 for Pulsar ZooKeeper nodes
8000, 3181, 4181 for Pulsar bookie nodes
6650, 6651, 8080, 8443 for Pulsar broker nodes

NOTE:

By default, this solution uses Pulsar 3.1.0 and deploys Java JDK-21 and Pulsar Manager 0.4.0.
A cluster named pulsar-cluster has been created in Pulsar by default.

(Optional) Modifying Security Group Rules

A security group is a collection of access control rules for traffic to and from cloud resources, such as cloud servers, containers, and databases. Cloud resources associated with the same security group have the same security requirements and are mutually trusted within a given VPC.

You can modify security group rules, for example, by adding, modifying, or deleting a TCP port, as follows:

Adding a security group rule: Add an inbound rule and enable a TCP port if needed.
Modifying a security group rule: Inappropriate security group settings may introduce serious security risks. You can modify security group rules to ensure the network security of your ECSs.
Deleting a security group rule: If the source or destination IP address of an inbound or outbound security group rule changes, or a port needs to be disabled, you can delete the security group rule.

Procedure

Log in to the ECS console to check whether the ECSs have been successfully created and check the EIP of the manager node.

Log in to the Pulsar Manager.

After ECSs are created, the environment starts to be deployed in the background. About 20 minutes later, the Pulsar cluster is created. Then, you can log in to the Pulsar Manager at http://manager-ip:9527.
CAUTION:
- Before logging in, ensure that port 9527 has been enabled on the Pulsar manager node for the client. If it is not enabled, modify security group rules.
- By default, admin is configured as the administrative user of the Pulsar cluster, and JSON Web Token (JWT) authentication is enabled.
- The default username and password are used for login.
  - Default username: admin
  - Default password: password used for creating ECSs
