# Systemd Unit

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

The unit files (`*.service` and `*.socket`) in this directory are 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`.
