Mengaktifkan rc.local di Debian 9 (Stretch)

Cara memberikan rc local di debian 9, yang mana kita harus manual memberikan dan mengaktifkan rc local sangat berbeda di debian versi sebelum sebelumnya...langsung saja kita praktekkan langkah demi langkah ::

1. Tambahkan direktory rc-local.service di /etc/sytemd/system/
#nano /etc/systemd/system/rc-local.service

isikan script dibawah ini
[Unit]
Description=/etc/rc.local
ConditionPathExists=/etc/rc.local

[Service]
Type=forking
ExecStart=/etc/rc.local start
TimeoutSec=0
StandardOutput=tty
RemainAfterExit=yes
SysVStartPriority=99

[Install]
WantedBy=multi-user.target
====================================================================
2. tambahkan script dibawah ini di lokasi rc.local
#nano /etc/rc.local
------------------------------------------------------------------------------------------------------
#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

exit 0
====================================================================
3. Berikan hak akses x untuk exsekusi di file rc.local
#chmod +x /etc/rc.local
====================================================================
4. Perintah untuk mengaktifkan rc-local ketika booting
#systemctl enable rc-local
====================================================================
5. Perintah untuk menjalankan script rc-local
#systemctl start rc-local.service
====================================================================
6. Cek status rc-local.service
#systemctl status rc-local.service
------------------------------------------------------------------------------------------------------
hasilnya
root@debian9putut:/home/putut# systemctl status rc-local.service
? rc-local.service - /etc/rc.local
