For starting up a webserver with instance launch, you can use user-data as below (Eg: for Amazon Linux AMI):

#!/bin/bash
yum update -y
yum install -y httpd
systemctl start httpd
systemctl enable httpd
usermod -a -G apache ec2-user
chown -R ec2-user:apache /var/www
chmod 2775 /var/www
find /var/www -type d -exec chmod 2775 {} \;
find /var/www -type f -exec chmod 0664 {} \;
cd /var/www/html
echo "<html><body><p><b>Hello from EC2</b></p></body></html>" >> index.html

Do note that for the above to work, the instance will need internet access when it launches. This can be via direct public IP association (i.e. Subnet setting) or options like NAT Gateway etc.
