haproxy service did not start automatically after running the script in the **create** mode #6

Accessing the cluster IP (10.240.0.2) for nginx service failed from my work computer:

[kamran@kworkhorse ~]$ curl http://10.240.0.2
curl: (7) Failed to connect to 10.240.0.2 port 80: Connection refused
[kamran@kworkhorse ~]$

Turned out that the haproxy service was not running. Whereas it should have been running!

Restarting the service, manually , worked!
