  2. To join the new node to the cluster, do one of the following:

    • From a meta node, run:

      influxd-ctl add-data <new_data_node_host>:<port>
    • From a remote server, run:

      influxd-ctl -bind <existing_meta_node:8091> add-data <new_data_node_host>:<port>
  3. (Optional) Rebalance the cluster.
