ec2在每次启动时运行脚本 [英] ec2 run scripts every boot

问题描述

我在这里关注了几篇文章，试图在每次引导后不仅在第一次引导后在ec2实例上运行python或shell脚本.

I have followed a few posts on here trying to run either a python or shell script on my ec2 instance after every boot not just the first boot.

我尝试过:

[始终是脚本用户]到/etc/cloud/cloud.cfg文件

• 已将脚本添加到./scripts/per-boot文件夹中

和

将脚本添加到/etc/rc.local

• 是的，/etc/rc.local的权限已更改为755

我正在尝试将文件的输出传递到/home/ubuntu/目录中的文件中，并且引导后该文件不包含任何内容.

I am attempting to pipe the output of the file into a file located in the /home/ubuntu/ directory and the file does not contain anything after boot.

如果我手动运行脚本(.sh或.py)，它们将起作用.

If I run the scripts (.sh or .py) manually they work.

是否有任何建议或要求其他信息的帮助?

Any suggestions or request for additional info to help?

推荐答案

因此，当前的解决方案似乎是我在最初的问题帖子中注销的一种方法，因为我可能未完全按照以下链接中的概述进行设置. ..

So the current solution appears to be a method I wrote off in my initial question post as I may have not performed the setup exactly as outline in the link below...

此链接-> 如何操作我让EC2实例每次启动时都运行cloud-init启动脚本吗?

链接显示了如何修改/etc/cloud/cloud.cfg 文件以将脚本用户更新为 [脚本用户，始终]

The link shows how to modify the /etc/cloud/cloud.cfg file to update scripts-user to [scripts-user, always]

该链接还显示将* .sh文件添加到/var/lib/cloud/scripts/per-boot 目录.

Also that link says to add your *.sh file to /var/lib/cloud/scripts/per-boot directory.

重新启动系统后，脚本应已执行，您可以在以下地址进行验证: sudo cat/var/log/cloud-init.log

Once you reboot your system your script should have executed and you can verify this in: sudo cat /var/log/cloud-init.log

如果脚本仍然无法执行，请尝试使用以下命令擦除服务器的实例状态: sudo rm -rf/var/lib/cloud/instance/*

if your script still fails to execute try to erase the instance state of your server with the following command: sudo rm -rf /var/lib/cloud/instance/*

-注意:- 似乎来自python脚本的打印命令未按预期进行管道(>>)，但回显命令却容易管道

--NOTE:-- It appears print commands from a python script do not pipe (>>) as expected but echo commands pipe easily

管道失败 sudo python test.py >> log.txt

管道成功 echo "HI" >> log.txt
