1.操作系统：CentOS6.6

2.任务：ssh key分发实验

3.操作过程如下：

[sky9890@A ~]$ ssh-keygen -t dsa

Generating public/private dsa key pair.

Enter file in which to save the key (/home/sky9890/.ssh/id_dsa): 

Created directory ‘/home/sky9890/.ssh‘.

Enter passphrase (empty for no passphrase): 

Enter same passphrase again: 

Your identification has been saved in /home/sky9890/.ssh/id_dsa.

Your public key has been saved in /home/sky9890/.ssh/id_dsa.pub.

The key fingerprint is:

59:c3:24:0d:9f:d1:cd:f9:06:02:ec:53:3f:67:c7:5e sky9890@A

......

[sky9890@A ~]$ ssh-copy-id -i .ssh/id_dsa.pub sky9890@192.168.152.128

-bash: ssh-copy-id: command not found   //问题

[sky9890@A ~]$ yum  -y  install openssh-clients //解决方法：

  安装成功之后，就可以做后续实验了，在这里后续实验环节描述了，此次实验关键在后续。
