Ssh password-free Login

Note:

Ssh password-less logon requires the public key and private key.

In linux or mac systems, you can use ssh-keygen to generate public/private key pairs.

 

1. Generate a key (~ /. Generate id_rsa and id_rsa.pub under the ssh directory.

Ssh-keygen-t rsa

2. Send the public key to the remote host ~ /Directory

Scp ~ /. Ssh/id_rsa.pub root@192.168.0.0 :~ /

3. log on to the remote host and append the public key to the authorization key.

Cat ~ /Id_rsa.pub> ~ /. Ssh/authorized_keys (grant 600 permission to chmod 600 authorized_keys)

4. Now you can log on normally.

Ssh root@192.168.0.0

5. To simplify login operations

~ /. Bashrc, add the following line: alias loginssh = "ssh root@192.168.0.0" and then source ~ /. Bashrc

6. Then you can log on more easily.

Loginssh
