编写脚本实现登陆远程主机（使用expect和shell脚本两种形式）

一、expect形式

1.安装expect

yum install expect -y
2.Expect脚本

#!/usr/bin/expect
set ip 10.0.0.149
set user yangchenghua
set password yangchenghua
set timeout 10
spawn ssh $user@$ip
expect {
"yes/no" { send "yes\n";exp_continue }
"password" { send "$password\n" }
}
interact

二、shell形式

#!/bin/bash
ip=10.0.0.7
user=root
password=********
expect <<EOF
set timeout 20
spawn ssh $user@$ip
expect {
"yes/no" { send "yes\n";exp_continue }
"password" { send "$password\n" }
}
expect eof
EOF
