Node Authentication¶
Authenticate Nodes Using SSH Keys¶
If you choose to authenticate the nodes of the cluster-to-be-created using SSH keys, you need to configure the public and private keys according to the following instructions.
-
Run the following command on any node within the management cluster of the cluster-to-be-created to generate the public and private keys.
-
Run the ls command to check if the keys have been successfully created in the management cluster. The correct output should be as follows:
The file named id_rsa is the private key, and the file named id_rsa.pub is the public key.
-
Run the following command to load the public key file id_rsa.pub onto all the nodes of the cluster-to-be-created.
Replace the user account and node IP in the above command with the username and IP of the nodes in the cluster-to-be-created. The same operation needs to be performed on every node in the cluster-to-be-created.
-
Run the following command to view the private key file id_rsa created in step 1.
The output should be as follows:
