Quick Creation of a Kafka Streaming Cluster

This section describes how to quickly create a Kafka streaming cluster. The Kafka cluster uses the Kafka and Storm components to provide an open-source messaging system with high throughput and scalability. It is widely used in scenarios such as log collection and monitoring data aggregation to implement efficient streaming data collection and real-time data processing and storage.

Quick Creation of a Kafka Streaming Cluster

  1. Log in to the MRS console.
  2. Click Create Cluster. The page for creating a cluster is displayed.
  3. Click the Quick Config tab.
  4. Configure basic cluster information. For details about the parameters, see Creating a Custom Cluster.

    • Region: Use the default value.
    • Cluster Name: You can use the default name. However, you are advised to include a project name abbreviation or date for consolidated memory and easy distinguishing, for example, mrs_20200321.
    • Cluster Version: The components provided by a cluster vary according to the cluster version. Select a cluster version based on site requirements.
    • Component: Select Kafka streaming cluster.
    • AZ: Use the default value.
    • VPC: Use the default value. If there is no available VPC, click View VPC to access the VPC console and create a new VPC.
    • Subnet: Use the default value.
    • Cluster Node: Select the number of cluster nodes and node specifications based on site requirements. For MRS 3.x or later, the memory of the master node must be greater than 64 GB.
    • Cluster HA: Use the default value. This parameter is not available in MRS 3.x.
    • Username: The default username is admin, which is used to log in to MRS Manager.
    • Password: Set a password for user admin.
    • Confirm Password: Enter the password of user admin again.
    • Key Pair: Select a key pair from the drop-down list to log in to an ECS. Select "I acknowledge that I have obtained private key file SSHkey-xxx and that without this file I will not be able to log in to my ECS." If you have never created a key pair, click View Key Pair to create or import a key pair. And then, obtain a private key file.

  5. Select Enable to enable secure communications. For details, see Communication Security Authorization.
  6. Click Apply Now.

    If Kerberos authentication is enabled for a cluster, check whether Kerberos authentication is required. If yes, click Continue. If no, click Back to disable Kerberos authentication and then create a cluster.

  7. Click Back to Cluster List to view the cluster status. Click Access Cluster to view cluster details.

    For details about cluster status during creation, see the description of the status parameters in Table 1.

    It takes some time to create a cluster. The initial status of the cluster is Starting. After the cluster has been created successfully, the cluster status becomes Running.

    On the MRS management console, a maximum of 10 clusters can be concurrently created, and a maximum of 100 clusters can be managed.
