You should have installed and configured Eucalyptus before starting the NC.
Log in to the Node Controller (NC) host machine.
If you want the NC service to start at each boot-time, run this command:
systemctl enable eucalyptus-node.service
Enter the following command to start the NC:
systemctl start eucalyptus-node.service
If you are running in EDGE networking mode:
If you want the eucanetd service to start at each boot-time, run this
systemctl enable eucanetd.service
Start the eucanetd service:
systemctl start eucanetd.service
Repeat for each NC host machine.
