Adding a Node to a Cluster

When a server is started for the first time, it is in a passive state.

Performing any RAFT command (such as listed below) will make the server become part of a cluster.

  • Adding a license
  • Creating a database on this server
  • Adding another node to this server cluster (will cause both to be part of the same cluster)

Adding a new Node

1. Enter the URL of the server for the new node
2. Decide if you will add the new node as a member -or- as a watcher (difference explained in Cluster View)
3. Click to use all available nodes -or- Enter the number of cores to be assigned for this node
4. Click Test connection to test the connection for the above url entered

When done, click Save to add this server as a node to the cluster

Now your cluster contains 2 nodes:

  • The server running on localhost:8081 shows as Node A and is the Leader of the cluster.
  • The server running on localhost:8082 shows as Node B and is a Member of the cluster.

More nodes can be added as needed.
