ubuntu开机启动python_在Ubuntu中启动时运行Python脚本

I have a short Python script that needs to run at startup - Ubuntu 13.10. I have tried everything I can think of but can't get it to run. The script:

#!/usr/bin/python

import time

with open("/home/username/Desktop/startup.txt", 'a') as f:

f.write(str(time.time()) + " It worked!")

(The actual script is a bit different, as I'm just using this for testing purposes, but you get the idea.)

I've tried all of the following, with no luck:

Put the command python startuptest.py in crontab, as @reboot

python /home/username/Documents/startuptest.py, both as the regular user and as sudo

Put the command python /home/username/Documents/startuptest.py in /etc/rc.local

Opened Ubuntu's Startup Applications and put the command there

Done all of the preceding, putting the command into a shell script

and calling that shell script instead

Nothing works. I get the feeling I'm missing something simple. Any ideas? (The script runs fine if I just run the command from a terminal.)

解决方案

Put this in /etc/init (Use /etc/systemd in Ubuntu 15.x)

mystartupscript.conf

start on runlevel [2345]

stop on runlevel [!2345]

exec /path/to/script.py

By placing this conf file there you hook into ubuntu's upstart service that runs services on startup.

manual starting/stopping is done with

sudo service mystartupscript start

and

sudo service mystartupscript stop
