在用capistrano 进行部署的时候，会希望专用一个web app来管理 这些部署 应用程序如：ccrb
那么ssh 也需要自动登陆出服务器上，如下：但这样不够安全，最好的是不定期的生成ssh密钥;
如：
客户机要想自动登陆到服务器192.168.188.199 上.
 1 . 在客户机上制作密钥
 2. 把密钥拷至服务器上，追加到.ssh/authorized_keys　文件中.

以下操作在  客户机   上进行

[root@ ~]# ssh-keygen -t dsa
Generating public/private dsa key pair.
Enter file in which to save the key (/root/.ssh/id_dsa): 
Enter passphrase (empty for no passphrase):   # 回车
Enter same passphrase again:  # 回车
Your identification has been saved in /root/.ssh/id_dsa.
Your public key has been saved in /root/.ssh/id_dsa.pub.
The key fingerprint is:
ad:85:bddb5:ddr:a544c:fc:ef:57:dd:4b:ef:a9:8a:db root@~

[root@ ~]# cd /root/.ssh/id_dsa
id_dsa      id_dsa.pub  
[root@ ~]# scp -P 65534 /root/.ssh/id_dsa.pub [email protected]:/root/.ssh/ 

在远程服务器上 完成

cd .ssh
umask 077
cat ./id_rsa.pub >> authorized_keys

回到客户机上用 ssh 192.168.188.199 -p65534
此时不用输密码即可登陆到服务器上.
