问题描述
我试图在用户数据中添加一些简单的bash命令,但看起来好像它们没有运行?

您正在使用ami-26ebbc5c
,它是 RHEL-7.4_HVM-20180103-x86_64-2-Hourly2-GP2 .. >
很可能(但我可能错了),此AMI上未安装cloud-init(用于处理用户数据).结果,什么也看不到用户数据.
您可以使用以下命令安装cloud-init:
yum install cloud-init
但是,这必须手动完成,然后生成一个新的AMI.
或者,您可以使用Amazon Linux或Ubuntu,它们默认都安装了cloud-init.

You are using ami-26ebbc5c
, which is RHEL-7.4_HVM-20180103-x86_64-2-Hourly2-GP2.
Most likely (but I could be wrong), cloud-init (which processes the User Data) is not installed on this AMI. As a result, nothing is looking at the User Data.
You could install cloud-init with:
yum install cloud-init
However, this would have to be done manually, and then a new AMI generated.
Alternatively, you could use Amazon Linux or Ubuntu, both of which have cloud-init installed by default.
