4 stars. The httpd server did not load (verified by inspecting the log). I restarted the image several times and even tried adding "logger" lines. After the first start, when I clicked on view log I got a black screen.

An FYI - There may be an issue when kicking off the labs instance with the user provided bash script. When reviewing the step 26 - Get System Log I could not validate validate the http package was installed from the user data. I was able to properly set up the Security Group to access the web server, but the test page was not being served at all. I suspected that there was an issue with the provided User Data script during the instance launch, To validate, I re-enable SSH and manually ran the commands to install the http package and found that there was a permission issue when trying to create the index.html file in the /var/www/html/ directory. I navigated to the /var/www/html/ directory and manually created the index.html file using 'sudo nano index.html' and dropping the html code in it. After restarting the httpd service the page rendered as expected in my browser. Thanks

Everything worked except the web server never worked. It gave connection refused, as if the http server never got installed. So, I launched another instance in the exact same way, but this time enabled an SSH key and added SSH 22 to the security group so I could ssh in and see what the problem was. It was stuck here, just hanging indefinitely: root 3252 0.1 3.0 147208 30964 ? Ss 04:11 0:00 /usr/bin/python /usr/bin/cloud-init modules --mode=final root 3259 0.0 0.0 4284 788 ?

S 04:11 0:00 \_ systemctl try-restart update-motd.service Anyhow, you should look into this. Somehow the "yum -y update" is causing the system to hang forever. I would recommend removing the "yum -y update" command from the user-data script you supply, so it doesn't get stuck here.
