Question

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。

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。

任何人都知道为什么？

这是原始用户数据：

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

所以我把它们放在这个多部分的Content-Type: text/x-shellscript;部分的末尾。试图在开始时也无济于事。

有什么想法吗？

Linux服务器上的用户数据必须在第一行有#!，否则不会以脚本形式执行。

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

请参阅：Advanced Environment Customization with Configuration Files (.ebextensions) - AWS Elastic Beanstalk

EC2用户数据脚本被完全忽略
