InfluxDB file system layout

This page documents an earlier version of InfluxDB OSS. InfluxDB OSS v2 is the latest stable version.

The InfluxDB file system layout depends on the operating system, installation method, or containerization platform used to install InfluxDB.

InfluxDB file structure

The InfluxDB file structure includes of the following:

Data directory

Directory path where InfluxDB stores time series data (TSM files). To customize this path, use the [data].dir configuration option.

WAL directory

Directory path where InfluxDB stores Write Ahead Log (WAL) files. To customize this path, use the [data].wal-dir configuration option.

Metastore directory

Directory path of the InfluxDB metastore, which stores information about users, databases, retention policies, shards, and continuous queries. To customize this path, use the [meta].dir configuration option.

InfluxDB configuration files

Some operating systems and package managers store a default InfluxDB configuration file on disk. For more information about using InfluxDB configuration files, see Configure InfluxDB.

When installing InfluxDB on Linux, you can download and install the influxd binary, or you can use a package manager. Which installation method you use determines the file system layout.
