Debian9开机运行Python脚本

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

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

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) 

添加/etc/rc.local

为了解决这个问题，我们需要手工添加一个 /etc/rc.local 文件

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 

赋予权限

chmod +x /etc/rc.local 

启动 rc-local 服务

systemctl start rc-local 

再次查看状态

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. 

添加命令启动

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

root@debian9 ~# vim /etc/rc.local

python /home/test.py &

exit 0
