Amazon EC2 - Labs - 02 - User Data

AWS > Compute > Amazon Elastic Compute Cloud (EC2):
When you launch an instance in Amazon EC2, you have the option of passing user data to the instance that can be used to perform common automated configuration tasks and even run scripts after the instance starts.

You can auto run update, install sofrware, run individual command when instance boot up.

To retrieve user data from within a running instance, use the following URL.

Lab Configuration:

#!/bin/bash
# software update
yum update -y
# Install httpd
yum install -y httpd
# Enable httpd service
service httpd start
# Make sure http always on next reboot
chkconfig httpd on
# Touch a index.html and Remove the "*"
cd /var/www/html
echo "<*html><*h1>Hello World!<*/h1><*/html>" > index.html
