Install DNSManager on CentOS 7x and write bash script to prepare OS for future deployments

I need DNSManager installed on a new CentOS 7x cloud server.

I am getting some install errors and can provide the solution from the vendor. In addition, I would like a small bash script written to fix the install errors on future deployments.

Project is marked urgent!
