Ubuntu EC2 - 重新启动时运行 Python 脚本

[英]Ubuntu EC2 - Run Python script on reboot

原文 2020-07-11 07:52:44 5 1 python/ amazon-web-services/ ubuntu/ amazon-ec2/ startup

I have an Ubuntu 16.04 EC2 Instance and I need to run a python script every time the instance is Started.我有一个 Ubuntu 16.04 EC2 实例，每次启动实例时我都需要运行 python 脚本。 I tried everything suggested on every question in the forum and haven't had any luck yet.我尝试了论坛中每个问题的所有建议，但还没有运气。

Specifically I've tested:具体来说，我已经测试过：

Adding @reboot python3 /home/project/script.py to crontab将@reboot python3 /home/project/script.py添加到 crontab
Adding @reboot /bin/startup.sh and having the bash file configured to run the /home/project/script.py添加@reboot /bin/startup.sh并配置 bash 文件以运行/home/project/script.py
Using etc/rc.local , etc/init/mystartup.conf , etc/systemd/mystartup.conf使用etc/rc.local ， etc/init/mystartup.conf ， etc/systemd/mystartup.conf
Passing User Data传递用户数据

Probably missing a few others and literally nothing worked even though running the script manually works wonders.可能缺少其他一些，即使手动运行脚本也能产生奇迹，但实际上没有任何效果。

Thanks a lot in advance for the help!非常感谢您的帮助！

Put the script into: /var/lib/cloud/scripts/per-boot/将脚本放入： /var/lib/cloud/scripts/per-boot/

Cloud-Init, which runs User Data, will also check this directory.运行用户数据的 Cloud-Init 也将检查此目录。

From Modules — cloud-init documentation :来自模块 — cloud-init 文档：

Any scripts in the scripts/per-boot directory on the datasource will be run every time the system boots.每次系统启动时，数据源上的scripts/per-boot目录中的任何脚本都会运行。 Scripts will be run in alphabetical order.脚本将按字母顺序运行。
