Debian 9.x “stretch” 解决 /etc/rc.local 开机启动问题

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，一般我们都是推荐添加命令到

/etc/rc.local

文件，但是 Debian 9 默认不带

/etc/rc.local

文件，而

rc.local

服务却还是自带的

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22

root@debian9 ~ # cat /lib/systemd/system/rc.local.service # 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 ConditionFileIsExecutable=/etc/rc.local After=network.target [Service] Type=forking ExecStart=/etc/rc.local start TimeoutSec=0 RemainAfterExit=yes GuessMainPID=no

并且默认情况下这个服务还是关闭的状态

1 2 3 4 5 6 7

root@debian9 ~ # systemctl status rc-local ● rc-local.service - /etc/rc.local Compatibility Loaded: loaded (/lib/systemd/system/rc-local.service; static; vendor preset: enabled) Drop-In: /lib/systemd/system/rc-local.service.d └─debian.conf Active: inactive (dead)

为了解决这个问题，我们需要手工添加一个

/etc/rc.local

文件

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

cat <<EOF >/etc/rc.local #!/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 EOF

然后赋予权限

1 2	chmod +x /etc/rc.local

接着启动

rc-local

服务

1 2	systemctl start rc-local

再次查看状态

1 2 3 4 5 6 7 8 9 10 11

root@debian9 ~ # systemctl status rc-local ● rc-local.service - /etc/rc.local Compatibility Loaded: loaded (/lib/systemd/system/rc-local.service; static; vendor preset: enabled) Drop-In: /lib/systemd/system/rc-local.service.d └─debian.conf Active: active (exited) since Thu 2017-08-03 09:41:18 UTC; 14s ago Process: 20901 ExecStart=/etc/rc.local start (code=exited, status=0/SUCCESS) Aug 03 09:41:18 xtom-proxy systemd[1]: Starting /etc/rc.local Compatibility... Aug 03 09:41:18 xtom-proxy systemd[1]: Started /etc/rc.local Compatibility.

然后你就可以把需要开机启动的命令添加到

/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
