1.操作系統：CentOS6.6
2.任務：ssh key分發實驗
3.操作過程如下：
[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 [email protected]
-bash: ssh-copy-id: command not found //問題
[sky9890@A ~]$ yum -y install openssh-clients //解決方法：
安裝成功之後，就可以做後續實驗了，在這裏後續實驗環節描述了，此次實驗關鍵在後續。
