Enable rc.local startup file on Debian 9 Stretch

Пример, как создать собственный сервис службу для запуска приложения.

The rc.local script is executed at boot time or when changing runlevels. Adding commands to the bottom of this script is an easy way to perform necessary tasks. However in Debian 9 it is removed by default, but you can add it back with a few steps.

1) Create file /etc/systemd/system/rc-local.service with the following content:

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) Create file rc.local in /etc with the following content:

#!/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) Add execute permissions to rc.local and enable the script:

chmod +x /etc/rc.local

systemctl enable rc.local

systemctl start rc-local.service

4) Edit rc.local and add your content

Note: you can check the status or errors using the command

systemctl status rc-local.service
