【笔记】Ubuntu18.04设置开机自启动文件/etc/rc.local

Ubuntu18.04没有/etc/rc.local，所以需要自己建立一个，具体方法如下：

1.修改rc-local.service文件

$ sudo vi /etc/systemd/system/rc-local.service

如下

#  SPDX-License-Identifier: LGPL-2.1+

#

#  This file is part of systemd.

#

#  systemd is free software; you can redistribute it and/or modify it

#  under the terms of the GNU Lesser General Public License as published by

#  the Free Software Foundation; either version 2.1 of the License, or

#  (at your option) any later version.

# This unit gets pulled automatically into multi-user.target by

# systemd-rc-local-generator if /etc/rc.local is executable.

[Unit]

Description=/etc/rc.local Compatibility

Documentation=man:systemd-rc-local-generator(8)

ConditionFileIsExecutable=/etc/rc.local

After=network.target

[Service]

Type=forking

ExecStart=/etc/rc.local start

TimeoutSec=0

RemainAfterExit=yes

GuessMainPID=no

[Install]

WantedBy=multi-user.target

Alias=rc-local.service

2.建立rc.local

$ sudo touch /etc/rc.local

如下

#!/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.

#输入希望开机自启动的程序

rfkill block bluetooth

#redshift

exit 0
