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.

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

# (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

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
