Membuat Layanan Otomatis Start Saat Server ON

Seringkali kita membutuhkan agar sebuah layanan/service dapat langsung jalan pada saat server boot. Untuk melakukan itu di ubuntu 20.04, kita perlu mengedit file /etc/rc.local, misalnya,

sudo nano /etc/rc.local

Isi dengan, misalnya,

1. !/bin/bash

<your_program>.sh exit 0

Jangan lupa save file rc.local. Ganti nama <your_program>.sh dengan nama yang anda suka. Contoh isi file <your_program>.sh, misalnya untuk menjalankan kiwix secara otomatis saat server boot, maka dapat kita isi dengan perintah, misalnya,

cd /usr/local/src/kiwix-tools_linux-x86_64-3.1.2-5/ ./kiwix-serve --port=8080 wikipedia_id_top_maxi_2021-09.zim & ./kiwix-serve --port=8081 wiktionary_id_all_maxi_2021-08.zim &

Pastikan file script bisa di jalankan dengan chmod

chmod 777 <your_program>.sh chmod +x <your_program>.sh

make rc.local executable:

sudo chmod +x /etc/rc.local

edit /etc/systemd/system/rc-local.service:

sudo nano /etc/systemd/system/rc-local.service

tambahkan content berikut ke rc.local.service:

enable rc.local oleh system service:

start rc.local oleh system service:

sudo systemctl start rc-local.service

kita dapat juga men-check rc.local status:

sudo systemctl status rc-local.service
