生成公钥密钥对-------------
[client@client ~]$ ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/home/client/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/client/.ssh/id_rsa.
Your public key has been saved in /home/client/.ssh/id_rsa.pub.
The key fingerprint is:
e7:46:65:43:9d:be:b6:1a:12:dc:31:69:a5:3b:b0:b2 client@client.localdomain
The key´s randomart image is:
