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_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.

The future of Flux

Flux is going into maintenance mode. You can continue using it as you currently are without any changes to your code.

Flux is going into maintenance mode and will not be supported in InfluxDB 3.0. This was a decision based on the broad demand for SQL and the continued growth and adoption of InfluxQL. We are continuing to support Flux for users in 1.x and 2.x so you can continue using it with no changes to your code. If you are interested in transitioning to InfluxDB 3.0 and want to future-proof your code, we suggest using InfluxQL.
