### <a id="systemd-service"></a> Systemd Service
Modern distributions (Fedora, OpenSUSE, etc.) already use `Systemd` natively. Enterprise-grade
distributions such as RHEL7 changed to `Systemd` recently. Icinga 2 Packages will install the
service automatically.
The Icinga 2 `Systemd` service can be (re)started, reloaded, stopped and also queried for its current status.

`Systemd` supports the following command actions:
Command | Description
--------------------|------------------------
start | The `start` action starts the Icinga 2 daemon.
stop | The `stop` action stops the Icinga 2 daemon.
restart | The `restart` action is a shortcut for running the `stop` action followed by `start`.
reload | The `reload` action sends the `HUP` signal to Icinga 2 which causes it to restart. Unlike the `restart` action `reload` does not wait until Icinga 2 has restarted.
status | The `status` action checks if Icinga 2 is running.
If you're stuck with configuration errors, you can manually invoke the [configuration validation](#config-validation).
