Add node to existing cluster

To add a data node to an existing cluster, follow the steps below.

  1. Install and start a new data node. Complete steps 1–3 of the data node installation instructions.
  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 address>:<port>
    • From a remote server, run:

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