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 
          address>:<port>
           ```
     

3. (Optional) Rebalance the cluster.
