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

[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
