I have an ec2 instance"abc1"(ubuntu) and I create image from abc1. Then,I launch a new instance "abc2" from abc1 image. I want abc2 to run the script when it will be launched.
So,I write the text in userdata:
我有一个ec2实例“abc1”(ubuntu)，我从abc1创建图像。然后，我从abc1映像启动一个新的实例“abc2”。我希望abc2在脚本启动时运行它。我用userdata写文本:
#!/bin/bash
cd ~/env/xxx/bin/
source activate
python3.6 ~/env/xxx/source/test.py
I manually use these commands,it's valid.However,it doesn't work when using userdata automatically. Does anyone know how to adjust my settings? Thanks a lot.
我手动使用这些命令，它是有效的。但是，当自动使用userdata时，它不能工作。有人知道怎么调整我的设置吗?非常感谢。

My guess is that you are ssh'ing into the ec2 instance as a different user than the instance is running it at, so the HOME directory (~) is not the same when run manually vs run with cloudinit.
我的猜测是，您正在ssh到ec2实例，因为与实例在其上运行的用户不同，所以当手动运行与使用cloudinit运行时，主目录(~)是不同的。
Try writing the script using absolute paths, not relative paths.
尝试使用绝对路径编写脚本，而不是相对路径。
