The service "${_srv}" has been enabled by default,
that means that it will be started in next boot. To start it immediately,
execute the following command (as root):
$ systemctl start ${_srv}
And to stop it:
$ systemctl stop ${_srv}
Refer to the systemd documentation if more information is required.
