A Redis Enterprise Software cluster typically consists of several nodes. For production deployments, we recommend an uneven number of nodes, with a minimum of three.

Note:
In a cluster that consists of only one node, some features and capabilities are not enabled, such as database replication that provides high availability.

To set up a new cluster, you must first install the Redis Enterprise Software package and then set up the cluster as described below. After the cluster is created you can add multiple nodes to the cluster.

To create a cluster:

  1. In a browser, navigate to https://<name or IP address of the machine with RS installed>:8443. For example, if you installed RS on a machine with IP address 10.0.1.34, then navigate to https://10.0.1.34:8443.

    Note:
    • The RS management UI uses a self-signed SSL/TLS encryption.
    • If the machine has both an internal IP address and an external IP address, use the external IP address to access the setup UI.
  2. Click Setup.

  3. In the Node Configuration page that appears:

    1. Enter a path for Persistent storage, or leave the default path.

    2. Enter a path for Ephemeral storage, or leave the default path.

    3. If you want to enable Redis on Flash, select the Enable flash storage support checkbox and enter the path to the Flash storage.

    4. If your machine is configured to have multiple IP addresses, the section IP Addresses Usage is shown. Use the IP Addresses Usage section to assign a single IPv4 type address for internal traffic and multiple IPv4/IPv6 type addresses for external traffic.

    5. In Cluster configuration, select Create new cluster.

    6. In Cluster name (FQDN), enter a unique name for the cluster. Also, make sure that you look at the [instructions for setting up DNS](/rs/installing-upgrading/configuring/cluster-dns/ to make sure your cluster is reachable by name.

    7. Choose whether to Enable private & public endpoints support.

    8. Choose whether to Enable rack-zone awareness. Enabling rack-zone awareness requires setting the Rack-zone ID for the node.

    9. Click Next.

  4. If you purchased a cluster key, use the Cluster authentication page to enter the key. Otherwise, you get the trial license by default. Read the product Terms and Conditions and click Next.

  5. Click OK to confirm that you are aware of the replacement of the HTTPS SSL/TLS certificate on the node, and proceed through the browser warning.

  6. In the Set admin credentials fields, enter the credentials of the cluster administrator.

  7. Click Next.

After a short wait, your cluster is created and you can log in to the RS admin console.

You can now access any of the management capabilities, including:
