[[email protected] ~]$ ssh-keygen-t RSA

Generating public/private RSA key pair.

Enter file in which to save the key (/HOME/DEVEN/.SSH/ID_RSA): (Enter)

Enter passphrase (empty for No passphrase): (carriage return)

Enter same passphrase again: (enter)

Your identification has been saved In/home/deven/.ssh/id_rsa.

Your public key has been saved in/home/deven/.ssh/id_rsa.pub.

The key fingerprint is:

89:56:D6:4A:B2:6C:4A:05:86:AE:CD:7D:80:DD:3C:F1 [email protected]

Intermediate Process Direct 3 carriage return. In the ~/.ssh/directory, two files were generated: Id_rsa (the private key file is placed locally) and id_rsa.pub (the public key file is placed on the trust server).

On Node2, do the same with the user Deven identity.

2. Summarize all public key file id_rsa.pub into a total authentication file Authorized-keys:

[email protected] ~]$ cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys

[[email protected] ~]$ ssh [email protected] Cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys

3. Currently there is a complete authentication key file on Node1, this time, copy it to the corresponding directory of the NODE2 host

[Email protected] ~]$ SCP ~/.ssh/authorized_keys [email Protected]:~/.ssh/authorized_keys

As with other users, the goal is to generate Id_rsa under/home/user/.ssh/, Id_rsa.pub, and then append id_rsa.pub to the Authorized_keys file of the cluster share.

It is recommended that all files under/home/user/.ssh/be set to 700 permissions.
