jika Anda tidak ingin bermigrasi ke UPSTART, tetapi menginginkan pendekatan klasik, Anda harus:
CATATAN: Saya menyimpan layanan dan program dengan nama yang sama di direktori yang berbeda (tetapi Anda dapat mengubahnya, asalkan tercermin dalam file layanan Anda). ubah "myscriptname" dan "myprogramname" menjadi nama asli!
simpan program Anda yang akan dijalankan sebagai layanan di / usr / sbin
sudo cp myprogramname /usr/sbin/myscriptname
buat skrip startup dasar (gunakan /etc/init.d/skeleton sebagai referensi)
pindahkan skrip ini ke /etc/init.d
sudo mv /etc/init.d/myscriptname
berikan skrip ini izin yang dapat dieksekusi (saya menggunakan 775, tetapi Anda dapat mengaturnya lebih rendah)
sudo chmod 755 /etc/init.d/myscriptname
goto /etc/init.d
cd /etc/init.d
termasuk dalam daftar startup dengan prioritas startup rendah
sudo update-rc.d myscriptname defaults 97 03
reboot mesin Anda dan periksa apakah layanan sudah dimulai dengan benar
sudo ps -A --sort cmd
jika layanan Anda tidak memulai dengan benar, Anda harus terlebih dahulu memeriksa apakah itu berjalan ketika dipanggil dengan tangan:
cd /etc/init.d
sudo service myscriptname start
di bawah ini saya sertakan file layanan sampel yang benar-benar berfungsi. bandingkan dengan layanan kerangka untuk memahami apa yang perlu Anda konfigurasi. CATATAN: ini berfungsi pada Ubuntu 12.04 amazon cloud AWS EC2 implementasi LAMP klasik (juga di Kubuntu 15.10).
