1.server 端:製作ssh 金鑰 會產生兩個檔案 id_dsa ; id_dsa.pub

[root@pc01]# ssh-keygen -t dsa

Generating public/private dsa key pair.

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

Enter passphrase (empty for no passphrase): （按enter）

Enter same passphrase again:（按enter）

[root@pc01 pbs]# ll /root/.ssh/id_dsa*

-rw------- 1 root root 668 2015-03-31 07:26 /root/.ssh/id_dsa

-rw-r--r-- 1 root root 599 2015-03-31 07:26 /root/.ssh/id_dsa.pub

2.client 端: 把server端的 id_dsa.pub 傳到client端 並重新命名為authorized_keys

[root@pc01]# ssh-copy-id -i /root/.ssh/id_dsa.pub root@pc02

[root@pc02 ~]# ls ~/.ssh/

authorized_keys
