Continue from the Enterprise Control Room installer to the Cluster Configuration wizard page. Use this page to setup the system IP addresses for configuring the Enterprise Control Room on single or multiple nodes (High Availability).

1. Enable Cluster Setup.
   The check box is enabled by default if the machine on which the setup is being run has local IP addresses configured.

   As part of cluster configuration the property, discovery.zen.minimum_master_nodes, is set elasticsearch.yml to handle split-brain in the Elasticsearchcluster.

   To install the Enterprise Control Room without a cluster, disable the Enable Cluster Setup check box.
2. Enter the IP addresses of the nodes for the cluster.
   1. Use a comma (,) to specify more than one IP address. For example, 192.161.1.1, 192.161.1.2, 192.161.1.3.

      If you supply invalid numbers or characters, an error message displays.

   2. After you correctly input the cluster IP addresses, a pop-up message prompts you to select a valid IP address that gives network access to this machine.
   3. Select the IP address from the Local IP Address drop-down list.

      If multiple local IP addresses are configured on the machine, select the IP address on which the Enterprise Control Room is installed because it will be used to access the Enterprise Control Room from other nodes.

3. Click Next to configure the application Transport Layer Security (TLS).
