How Do I Troubleshoot the Failure to Remotely Log In to a Node in a CCE Cluster?
After creating a node on CCE, you cannot remotely log in to the node using SSH. A message is displayed indicating that the selected key has not been registered on the remote host. In this case, the root user cannot directly log in to the node.
The cause is that the cloud-init is installed on the node on CCE. For the cloud-init, a default Linux user already exists and the user's key is also used for the device running Linux.
Solution
Log in to the device as the Linux user, and run the sudo su command to switch to the root user.
