Note:
Rebooting a compute node is different from restarting a compute node. Restarting a compute node, as described in Restarting a MySQL Server Deployment, stops and removes the Compute Cloud Service instance on which the compute node is running and then creates and starts a new Compute Cloud Service instance for the compute node. Rebooting a compute node uses a Linux command to restart the Compute Cloud Service instance on which the compute node is running.
