Gunakan ModifyCluster dengan AWS SDK atau CLI

Mengaitkan Grup Keamanan dengan ClusterThis contoh menunjukkan cara mengaitkan grup keamanan klaster dengan Cluster.command yang ditentukan:

aws redshift modify-cluster --cluster-identifier mycluster --cluster-security-groups mysecuritygroup

Ubah Jendela Pemeliharaan untuk ClusterThis menunjukkan cara mengubah jendela pemeliharaan pilihan mingguan untuk cluster menjadi jendela minimum empat jam mulai hari Minggu pukul 11:15, dan berakhir Senin pukul 3:15 pagi. Perintah:

aws redshift modify-cluster --cluster-identifier mycluster --preferred-maintenance-window Sun:23:15-Mon:03:15

Ubah Kata Sandi Master untuk ClusterThis contoh menunjukkan cara mengubah kata sandi master untuk cluster.Command:

aws redshift modify-cluster --cluster-identifier mycluster --master-user-password A1b2c3d4

Memodifikasi cluster.

    public static void modifyCluster(RedshiftClient redshiftClient, String clusterId) {
        try {
            ModifyClusterRequest modifyClusterRequest = ModifyClusterRequest.builder()
                .clusterIdentifier(clusterId)
                .preferredMaintenanceWindow("wed:07:30-wed:08:00")
                .build();

            ModifyClusterResponse clusterResponse = redshiftClient.modifyCluster(modifyClusterRequest);
            System.out.println("The modified cluster was successfully modified and has "
                + clusterResponse.cluster().preferredMaintenanceWindow() + " as the maintenance window");

        } catch (RedshiftException e) {
            System.err.println(e.getMessage());
            System.exit(1);

Buat klien.

import { RedshiftClient } from "@aws-sdk/client-redshift";
// Set the AWS Region.
const REGION = "REGION";
//Set the Redshift Service Object
const redshiftClient = new RedshiftClient({ region: REGION });
export { redshiftClient };

Memodifikasi cluster.

// Import required AWS SDK clients and commands for Node.js
import { ModifyClusterCommand } from "@aws-sdk/client-redshift";
import { redshiftClient } from "./libs/redshiftClient.js";

// Set the parameters
const params = {
  ClusterIdentifier: "CLUSTER_NAME",
  MasterUserPassword: "NEW_MASTER_USER_PASSWORD",
};

const run = async () => {
  try {
    const data = await redshiftClient.send(new ModifyClusterCommand(params));
    console.log("Success was modified.", data);
    return data; // For unit tests.
  } catch (err) {
    console.log("Error", err);
  }
};
run();
