SSH keyless key between servers

1 Open No key

To configure HDFs, you first have to configure the non-key between the machines. We are here for convenience, the two-way non-key between the machine is configured.

(1) Generate RSA key information

SSH-KEYGEN-T RSA

All the way to the return until a graphical structure is generated, the RSA private key ID_RSA and the public key id_rsa.pub are created in the/home/user/.ssh directory.

(2) Copy the SSH certificate public key of all machine nodes to the/home/user/.ssh/authorized_keys file, three machines are the same.

(3) switch to the root user, modify the/etc/ssh/sshd_config file, configure:

Rsaauthentication yespubkeyauthentication yesauthorizedkeysfile      . Ssh/authorized_keys

(4) Restart SSH services: Service sshd restart

(5) using the SSH service, Telnet:

SSH configuration succeeded.
