Configure the Primary Master Node in an Atlas Cluster
The primary master node is the master node in the Bomgar cluster that is configured as the primary site in failover. Information on configuring the Bomgar Appliance for failover is available in the Failover Configuration document. The network in which the master lives should be a central location in relation to your network as a whole.
Note: It is a best practice to set up two master nodes in a failover relationship. However, it is possible though not recommended to have only one master node.
Perform the following steps on the primary master node:
- Go to /login > Management > Cluster.
- Look at the Cluster :: Master Node Configuration section.
- Enter the following information in the Primary master node section:
- Name: Enter a name that you will use to remember this node in the cluster. This name must be unique among all nodes in the cluster.
- Public Address:
- Enter the node hostname that you set up in DNS for this node. This should be the canonical hostname unique to the master node, not the primary hostname for the entire cluster (e.g., master.example.com, not support.example.com). (See Prerequisites to Set Up Multiple Appliances in Atlas Clusters.)
- Enter the port over which clients will communicate with the node. This will usually be port 443.
- Internal Address: This can be the same as the public address. Advanced configurations can optionally set this to a different hostname for inter-appliance communication. (See Optional Considerations when Setting Up Multiple Appliances in Atlas Clusters.)
Note: While IP addresses are recommended for failover setups, Bomgar does not currently support IP address usage for Atlas clusters. All master nodes (primary and failover) as well as traffic nodes should use their unique node hostnames. They should NOT use the primary public hostname of the entire cluster or their unique public and/or private IP addresses.
- Click Create New Cluster.
Note: If the primary master appliance is in a failover synchronization with a backup master, then the backup master is added to the cluster automatically. Ift the primary master node is put in failover with a new backup appliance, the new backup appliance is added to the cluster automatically, and the cluster settings are synced to the new backup during the process of establishing failover.
