截一段吧：

1.登录ServerA

2.ssh-keygen -t rsa，将会生成公钥和私钥文件id_rsa和id_rsa.pub【如果一直回车下去，最后这两个文件应该在/home/$USER/.ssh下面】

3.将 .pub 文件复制到ServerB机器的 .ssh 目录下，并保存为authorized_keys

可以使用：

ssh-cop-id命令会将指定的公钥文件复制到远程计算机

[Oracle@Test232 ~]$ ssh-copy-id -i ~/.ssh/id_rsa.pub oracle@192.168.55.232
28
oracle@192.168.55.232's password:
Now try logging into the machine, with "ssh 'oracle@192.168.55.232'", and check in:

.ssh/authorized_keys

to make sure we haven't added extra keys that you weren't expecting.

[oracle@Test232 ~]$ ssh oracle@192.168.55.232
oracle@192.168.55.232's password:
Last login: Thu Nov 24 16:05:32 2011 from 192.168.55.229
[oracle@Test232 ~]$

4.大功告成，从A机器登录B机器的目标账户，不再需要密码了
