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:

     shCopy

     influxd-ctl add-data <new_data_node_host>:<port>
     

   • From a remote server, run:

     shCopy

     influxd-ctl -bind <existing_meta_node:8091> add-data <new_data_node_host>:<port>
     

3. (Optional) Rebalance the cluster.
