ssh shell 登录命令讲解

我们先试一试无密码登录执行命令:

ssh -o "StrictHostKeyChecking no" username@host << remotessh

执行的命令

remotessh

有密码登路：

yum install expect

编写脚本

#!/usr/bin/expect -f

set timeout 30

set username "root"

set password "123456"

spawn ssh -o "StrictHostKeyChecking no" $username@host  #跳过yes

expect "password:"   #上一次输出是否有"password:" 字符串

send "$password\r"   #发送密码

interact #保持连接

expect eof
