# Modify systemd script
modify _kafka.service_ by applying [this template](./kafka.service) to /etc/systemd/system/kafka.service
followed by executing:
```
sudo systemctl daemon-reload
```
FOR KAFKA
If Zookeeper is added as service, then add the 'Requires' parameter to the unit section. So when kafka is started it will start zookeeper service automatically.
