Troubleshoot systemd errors
When running InfluxDB using systemd (Ubuntu, Debian, CentOS), you might encounter errors in the InfluxDB logs (via
journalctl -u influxdb) like:
error msg="Unable to open series file"
run: open server: open tsdb store: mkdir /var/lib/influxdb/data/_internal/_series/00: permission denied
When InfluxDB is installed with systemd, an
influxdb user and group is automatically created.

In this case, when systemd starts the InfluxDB service (via
sudo systemctl start influxdb),
the InfluxDB process will exit because it cannot access the leftover files owned by the
To resolve this issue, set all files in the InfluxDB directories to be owned by the
influxdb user and group.
Run the following command:
sudo chown -R influxdb:influxdb /var/lib/influxdb/*
Alternatively, if the data is not important, reset the database by removing all files:
sudo rm -rf /var/lib/influxdb/
