User-data scripts is not running on my custom AMI, but working in standard Amazon linux

Question

I searched a lot of topic about \"user-data script is not working\" in these few days, but until now, I haven\'t gotten any idea about my case yet, please help me to figure

Answer 1

The only way I get it to work was to add the #cloud-boothook before the #!/bin/bash

This is a typical user data script that installs Apache web server on a newly created instance

#cloud-boothook
#!/bin/bash

yum update -y 
yum install -y httpd.x86_64 
systemctl start httpd.service 
systemctl enable httpd.service 

without the #cloud-boothook it does not work, but with it, it works. It seems that different users have different experiences. Some are able to get it to work without it, not sure why.
