ssh+expect批量分发

Expect安装

[root@web02 scripts]# yum install expect

SSH密钥生成

[root@web02 scripts]# ssh-keygen -t dsa   <==生成密钥

Generating public/private dsa key pair.

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

Enter passphrase (empty for no passphrase):

Enter same passphrase again:

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:

d8:a6:e4:1f:8a:9a:25:f9:39:6c:74:1e:69:78:78:11 root@web02

The key's randomart image is:
