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]: 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@Samba96-21:/home/user# ls

images  ServerStatus

root@Samba96-21:/home/user# cd ServerStatus/

root@Samba96-21:/home/user/ServerStatus# pwd

/home/user/ServerStatus

root@Samba96-21:/home/user# vim.tiny /etc/rc.local

/usr/bin/python3 /home/user/ServerStatus/ServerStatus.py &

exit 0
