Создадим скрипт для запуска и остановки службы Samba.

touch /etc/init.d/samba4
chmod +x /etc/init.d/samba4

Добавим в него следующее содержимое.

#!/bin/sh

Попробуем запустить Samba.

# /etc/init.d/samba4 start
 * Starting Samba daemon                                                 [ OK ]

Добавим службу в автозагрузку.

# update-rc.d samba4 defaults
update-rc.d: warning: /etc/init.d/samba4 missing LSB information
update-rc.d: see 
 Adding system startup for /etc/init.d/samba4 ...

   /etc/rc4.d/S20samba4 -> ../init.d/samba4
   /etc/rc5.d/S20samba4 -> ../init.d/samba4

Перезагрузим сервер.

# reboot

Проверим, запустилась ли Samba.
