# Systemd Unit

If you are using distribution packages or the copr repository, you don't need to deal with these files!

The unit file in this directory is to be put into `/etc/systemd/system`.
It needs a user named `node_exporter`, whose shell should be `/sbin/nologin` and should not have any special privileges.
It needs a sysconfig file in `/etc/sysconfig/node_exporter`.
It needs a directory named `/var/lib/node_exporter/textfile_collector`, whose owner should be `node_exporter`:`node_exporter`.
A sample file can be found in `sysconfig.node_exporter`.
Mention copr yum repository, add systemd unit (#529) * add systemd unit as example * mention community yum repo fixes #498 * rename textfile collector dir 2017-04-19 09:54:15 -07:00			`# Systemd Unit`

Update systemd example readme file (#1663) The readme file does not mention the need to create a folder named /var/lib/node_exporter/textfile_collector as a step. Lack of this folder results errors for node_exporter service which is visible in systemd status output. These errors possibly harmless but it is not good to have them still. $ sudo systemctl status node_exporter --- snipped --- Apr 04 14:51:35 ubuntu node_exporter[14713]: level=info ts=2020-04-04T14:51:35.584Z caller=node_exporter.go:190 msg="Listening on" address=:9100 Apr 04 15:05:34 ubuntu node_exporter[14876]: level=error ts=2020-04-04T15:05:34.464Z caller=textfile.go:197 collector=textfile msg="failed to read textfile collector directory" path=/var/lib/node_exporter/textfile_collector=textfile msg="failed to read textfile collector directory" path=/var/lib/node_exporter/textfile_collector err="open /var/lib/node_exporter/textfile_collector: no such file or directory" --- snipped --- Signed-off-by: Fatih Degirmenci <fdegir@gmail.com> 2020-04-06 06:32:02 -07:00			It needs a directory named `/var/lib/node_exporter/textfile_collector`, whose owner should be `node_exporter`:`node_exporter`.
