EC2用户数据脚本被完全忽略

I took the userdata for the ElasticBeanstalk AMI to try and add some stuff of my own. Should be easy.

我使用了ElasticBeanstalk AMI的userdata来尝试添加我自己的一些东西。应该很容易。

Specially because there is already a session in the userdata where some shell script is run. So I put my stuff there and it gets completely ignored. It doesn't run, it doesn't log anything, it produces exactly zero results.

特别是因为在userdata中已经有一个会话，其中运行了一些shell脚本。所以我把我的东西放在那里，它完全被忽略了。它不会运行，它不会记录任何内容，它会产生完全零结果。

Anyone knows why?

谁知道为什么？

This is the original user-data:

I'm trying to add this series of commands to it:

我正在尝试添加这一系列命令：

aws s3 cp s3://oidevops/beanstalk/application-configs/chatbot-admin/dev/91_install_cloudwatchlogs_agent.sh .
aws s3 cp s3://oidevops/beanstalk/application-configs/chatbot-admin/dev/91_awslogs_restart.sh .
chmod 750 91install_cloudwatchlogs_agent.sh && chmod 750 91_awslogs_restart.sh
cp 91_install_cloudwatchlogs_agent.sh /opt/elasticbeanstalk/hooks/appdeploy/post
cp 91_awslogs_restart.sh /opt/elasticbeanstalk/hooks/restartappserver/post
cp 91_awslogs_restart.sh /opt/elasticbeanstalk/hooks/configdeploy/post

So I placed them at the end of the Content-Type: text/x-shellscript; section of this multipart. Tried at the beggining too, to no avail.

所以我将它们放在Content-Type：text / x-shellscript的末尾;这部分的一部分。试图开始也无济于事。

Any ideas?

有任何想法吗？

User Data on Linux servers must have #! on the first line, otherwise it is not executed as a script.

Linux服务器上的用户数据必须有＃！在第一行，否则它不作为脚本执行。

If you wish to add software to an Elastic Beanstalk environment, you should use .ebextensions.

如果您希望将软件添加到Elastic Beanstalk环境，则应使用.ebextensions。
