Install Mysql cluster using the auto installer Help!! (no replies)

Hi. Im really having a problem getting this mysql cluster to work. I have tried to install it manually and that didnt work and now made a new set of vms to try the auto installer and what i did was download the binaries(Note RedHat 7 vm's) and unzip them in /usr/local/ and made a folder named mysql-cluster-gpl-7.5.8-linux-glibc2.12-x86_64 then in the installer i set the install folder /usr/local/mysql-cluster-gpl-7.5.8-linux-glibc2.12-x86_64/ for each server and made a data folder in /usr/local/clusterdata/ and pasted that path into the installer and all looks good. I click deploy and start cluster it creates everything and when it goes to start it. it hangs on the for management node and doesn't do anything. I have tried to make the path to the nbd_mgmd file
/usr/local/mysql-cluster-gpl-7.5.8-linux-glibc2.12-x86_64/bin/
With no change.

Is there something im missing?

Thanks for any help you can give!
