Licode installation issues with CentOS Server 7

Licode when installed on CentOS server 7 ,it was found that multiple
instances of Erizo Controller were running.And one more thing when we
executed the script many rabbitMQ process started running ,to
be precise as many as 5.May I know what is the issue and whether is it
result of some dependency issues or something else as we can find out
from the scripts folder that a file for CentOS dependency exists.Same thing
when run on Ubuntu 14.04 ran smoothly without any issues.
