influxd-ctl join
The influxd-ctl join command joins a meta or data node data node to an
InfluxDB Enterprise cluster.
The command searches for influxd and influxd-meta processes running on the
local machine bound to specific ports and determines if that process is an
InfluxDB meta or data node.
- 8088: Data node
- 8091: Meta node
If the InfluxDB data or meta processes are running on non-default ports, the join operation cannot detect them.
Usage
influxd-ctl join [flags] <meta-node-http-bind-address>
Arguments
- meta-node-http-bind-address: HTTP bind address of a meta node in an existing cluster. Use this argument to add un-joined meta or data node to an existing cluster.
Flags
| Flag | Description |
|---|---|
-p |
Add the data node as a passive node |
-v |
Print verbose information when joining |
Also see influxd-ctl global flags.
Examples
- Join a meta and data node into a cluster
- Join a meta and data node to an existing cluster
- Join a meta node to an existing cluster
Join a meta and data node into a cluster
In the following example, influxd-ctl join command detects a meta node process
running at cluster-node-03:8091 and a data node process running at
cluster-node-03:8088 and joins them into a new cluster.
influxd-ctl join
Command output
Joining meta node at localhost:8091
Searching for meta node on cluster-node-03:8091...
Searching for data node on cluster-node-03:8088...
Successfully created cluster
* Added meta node 1 at cluster-node-03:8091
* Added data node 2 at cluster-node-03:8088
To join additional nodes to this cluster, run the following command:
influxd-ctl join cluster-node-03:8091
Join a meta and data node to an existing cluster
In the following example, influxd-ctl join detects a meta node process running
at cluster-node-03:8091 and a data node process running at cluster-node-03:8088.
It uses the meta node running at cluster-meta-node-02:8091 in an existing
cluster to join the newly detected meta and data nodes to the cluster.
influxd-ctl join cluster-meta-node-02:8091
Command output
Joining meta node at cluster-meta-node-02:8091
Searching for meta node on cluster-node-03:8091...
Searching for data node on cluster-node-03:8088...
Successfully joined cluster
* Added meta node 3 at cluster-node-03:8091
* Added data node 4 at cluster-node-03:8088
Join a meta node to an existing cluster
In the following example, influxd-ctl join detects a meta node process running
at cluster-meta-node-03:8091, but does not detect a data node process.
It uses the meta node running at cluster-meta-node-02:8091 in an existing
cluster to join the newly detected meta node to the cluster.
influxd-ctl join cluster-meta-node-02:8091
Command output
Joining meta node at cluster-meta-node-02:8091
Searching for meta node on cluster-meta-node-03:8091...
Searching for data node on cluster-meta-node-03:8088...
Successfully joined cluster
* Added meta node 18 at cluster-meta-node-03:8091
* No data node added. Run with -v to see more information
Troubleshoot influxd-ctl join
Common problems when attempting to join nodes to InfluxDB Enterprise clusters:
- The
influxdorinfluxd-metaprocesses are using non-standard ports and can’t be detected. - The
influxdorinfluxd-metaprocesses are not running. Check the logs for startup errors.
