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 initLicode.sh 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.
