1. In a browser, go to `https://<name-or-IP-address-of-the-machine-with-Redis-Enterprise-Software-installed>:8443` to access the Cluster Manager UI. If you use a browser on the host machine, you can also access the Cluster Manager UI at `https://localhost:8443`.

    The cluster generates self-signed TLS certificates to secure the connection. Because these self-signed certificates are unknown to the browser, you must accept them before you proceed.

    If the server does not show the sign-in screen, try again after a few minutes.

1. Select **Create new cluster**.

2. Enter an email and password for the administrator account, then select **Next** to proceed to cluster setup.

    You can also use these credentials to connect to the [REST API]({{< relref "/operate/rs/references/rest-api" >}}).

3. Enter your cluster license key if you have one. Otherwise, a trial version is installed.

4. In the **Configuration** section, enter a cluster FQDN such as `cluster.local`, then select **Next**.

    {{< warning >}}
If the FQDN is `cluster.local`, you cannot configure DNS. You cannot change the FQDN after cluster creation.

1. On the node setup screen, select **Create cluster** to accept the defaults.

6. Select **OK** to acknowledge the replacement of the HTTPS TLS certificate on the node.  If you receive a browser warning, you can proceed safely.
