This script is based on one published in the Kafka Cluster Setup on Udemy. The script in there was made for Ubuntu but I needed it to run in Amazon Linux. Instead of using update-rc.d it uses chkconfig
Set up kafka as a service so that you can do sudo service kafka start

sudo nano /etc/init.d/kafka
# Paste the contents in this gist and save the file
sudo chmod +x /etc/init.d/kafka
sudo chown root:root /etc/init.d/kafka
sudo chkconfig --add kafka
sudo chkconfig kafka on
sudo service kafka start
