本文同样适用于 Debian 10 Buster 和 Debian 9 Strech。 由于某些软件并没有增加开启启动的服务,很多时候需要手工添加,一般我们都是推荐使用 并且默认情况下这个服务还是关闭的状态: 为了解决这个问题,我们需要手工添加一个 然后赋予权限: 接着启动 此时可能会弹出警告: 无视警告,因为这个服务没有任何依赖的系统服务,只是开机启动 再次查看状态: 然后你就可以把需要开机启动的命令添加到 systemd
写个系统服务,但是对于一些简单的脚本或者懒人来说,添加命令到 /etc/rc.local
文件更方便,但是自从 Debian 9 开始,Debian 默认不带 /etc/rc.local
文件,而 rc.local
服务却还是自带的:root@debian ~ # cat /lib/systemd/system/rc-local.service# SPDX-License-Identifier: LGPL-2.1-or-later## 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]

rc-local
服务:systemctl enable --now rc-local
The unit files have no installation config (WantedBy=, RequiredBy=, Also=,
Alias= settings in the [Install] section, and DefaultInstance= for template
units). This means they are not meant to be enabled using systemctl.
Possible reasons for having this kind of units are:
• A unit may be statically enabled by being symlinked from another unit's
.wants/ or .requires/ directory.
• A unit's purpose may be to act as a helper for some other unit which has
a requirement dependency on it.
• A unit may be started when needed via activation (socket, path, timer,
D-Bus, udev, scripted systemctl call, ...).
• In case of template units, the unit is meant to be enabled with some
instance name specified.
/etc/rc.local

文件,丢在 exit 0
前面即可,并尝试重启以后试试是否生效了。
