expect交互脚本

## expect 在base源，这里我用的是阿里云的YUM源，有base源可以忽略
[root@Shell ~]# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
[root@Shell ~]# yum makecache
## 用yum安装expect
[root@Shell ~]# yum install expect -y

#!/usr/bin/expect
## 设定变量password等于123.com
set password 123.com
## 新建一个进程，执行ssh命令
spawn ssh root@192.168.1.2
expect {
    ## 当询问
    "yes/no" { send "yes\r"; exp_continue }
    "password" { send "$password\r" }
}
interact

#!/usr/bin/expect
## 位置参数传递
set ip [lindex $argv 0]
set user root
set password 123.com
set passwd 456.com
## 响应等待5秒，超时进入下一条
set timeout 5
spawn ssh $user@$ip
expect {
    "yes/no" { send "yes\r"; exp_continue }
    "password" { send "$password\r" };
}
# 当出现 # 号符执行如下命令
expect "#"
send "useradd yunxiang\r"
send "passwd yunxiang\r"
expect {
    "New password:" { send "$passwd\r"; exp_continue }
    "Retype new password:" { send "$passwd\r" }
}
send "exit\r"
## 都执行完了就退出
expect eof

#!/usr/bin/bash
password="123.com"
## 清空ip.txt文件
>ip.txt
## 使用循环把ping通ip放到ip.txt文件中
for i in {2..10}
do
    ip=192.168.1.$i
    {
    ping -c1 -W1 $ip &>/dev/null
    if [ $? -eq 0 ];then
        echo "$ip" >> ip.txt
    fi
    }&
done
## 生成对应的密钥
if [ ! -f ~/.ssh/id_rsa ];then
    ssh-keygen -P "" -f ~/.ssh/id_rsa
fi
## 把ip.txt文件以每行循环
while read line
do
    ## 调用expect
    /usr/bin/expect <<-EOF
    set timeout 5
    spawn ssh-copy-id $line -f
    expect {
        "yes/no" { send "yes\r"; exp_continue }
        "password:" { send "$password\r" }
    }
    expect eof
    EOF
done<ip.txt

#!/bin/bash
password="123"
> ip.txt
if [ ! -f ~/.ssh/id_rsa ]
then
    ssh-key-id -P "" -f ~/.ssh/id_rsa
fi
for i in {2..10}
do
    ip=192.168.1.$i
    ping -c 1 -W 1 $ip > /dev/null
    if [ $? -eq 0 ]
    then
        /usr/bin/expect <<-EOF
        set timeout 5
        spawn ssh-copy-id $ip -f
        expect {
            "yes/no" { send "yes\r"; exp_continue }
            "password" { send "$password\r" }
        }
        expect eof
        EOF >> ip.txt
    fi
done
