## Enabled ports
|
|
|
|
### 8086
|
|
|
|
The default port that runs the InfluxDB HTTP service.
|
|
It is used for the primary public write and query API.
|
|
Clients include the CLI, Chronograf, InfluxDB client libraries, Grafana, curl, or anything that wants to write and read time series data to and from InfluxDB.
|
|
[Configure this port](/enterprise_influxdb/v1.8/administration/config-data-nodes/#bind-address-8088)
|
|
in the data node configuration file.
|
|
|
|
_See also: [API Reference](/influxdb/v1.8/tools/api/)._
|
|
|
|
### 8088
|
|
|
|
Data nodes listen on this port.
|
|
Primarily used by other data nodes to handle distributed reads and writes at runtime.
|
|
Used to control a data node (e.g., tell it to write to a specific shard or execute a query).
|
|
It's also used by meta nodes for cluster-type operations (e.g., tell a data node to join or leave the cluster).
|
|
|
|
This is the default port used for RPC calls used for inter-node communication and by the CLI for backup and restore operations
|
|
(`influxdb backup` and `influxd restore`).
|
|
[Configure this port](/influxdb/v1.8/administration/config#bind-address-127-0-0-1-8088)
|
|
in the configuration file.
|
|
|
|
This port should not be exposed outside the cluster.
|
|
|
|
_See also: [Backup and Restore](/influxdb/v1.8/administration/backup_and_restore/)._
|
|
|
|
### 8089
|
|
|
|
Used for communcation between meta nodes.
|
|
It is used by the Raft consensus protocol.
|
|
The only clients using `8089` should be the other meta nodes in the cluster.
|
|
|
|
This port should not be exposed outside the cluster.
|
|
|
|
### 8091
|
|
|
|
Meta nodes listen on this port.
|
|
It is used for the meta service API.
|
|
Primarily used by data nodes to stay in sync about databases, retention policies, shards, users, privileges, etc.
|
|
Used by meta nodes to receive incoming connections by data nodes and Chronograf.
|
|
Clients also include the `influxd-ctl` command line tool and Chronograph,
|
|
|
|
This port should not be exposed outside the cluster.
