File system layout Concepts

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.

Installed as a package

InfluxDB 2.0 supports .deb- and .rpm-based Linux package managers. The file system layout is the same with each.

Linux default directories (package)

Path Default
Data directory /var/lib/influxdb/data/
WAL directory /var/lib/influxdb/wal/
Metastore directory /var/lib/influxdb/meta/
Default config file path /etc/influxdb/influxdb.conf

Directory permissions

The user running the influxd process should have the following permissions for directories in the InfluxDB file system:

Directory path Permission
.../influxdb/ 755
.../influxdb/data/ 755
.../influxdb/meta/ 755
.../influxdb/wal/ 700
