linux expect脚本文件分发系统

（以下示例思路来自猿课阿铭linux）

远程分发文件基础知识

scp 文件 目标IP:绝对路径

scp 1.txt 192.168.153.134:/tmp/

远程分发目录

scp -r

 

rsync  增量备份（本地远程都可用）

rsync -av 文件目录  目标IP:目标目录

 

构建文件分发系统

使用expect脚本批量把需要同步的文件分发到目标机器

核心命令 ：rsync -av –files-from=list.txt /root@hostname:/

实现：

cat rsync.expect

#!/usr/bin/expect

set passwd "*******"

set host [lindex $argv 0]

set file [lindex $argv 1]

spawn rsync -av --files-from=$file /root@$host:/

expect {

"yes/no" { send"yes\r"}

"password:" { send "$passwd\r"}

}

expect eof

 

cat ip.list

192.168.153.134

192.168.153.135

192.168.153.136

192.168.153.137

 

cat rsync.sh

#!/bin/bash

for ip in `cat ip.list`

do

       echo$ip

       ./rsync.expect$ip list.txt

done

 

cat list.txt

/root/1.expect

/tmp/1.txt

/tmp/a.txt

/tmp/A.txt

/tmp/b.txt

/tmp/B.txt

 

命令批量执行脚本

 

cat exe.expect

#!/usr/bin/expect

set host [lindex $argv 0]

set passwd "********"

set cm [lindex $argv 1]

 

spawn ssh root@$host

 

expect {

"yes/no" { send"yes\r"}

"password:" { send"$passwd\r" }

}

expect "]*"

send "$cm\r"

expect "]*"

send "exit\r"

 

cat exe.sh

#!/bin/bash

for ip in `cat ip.list`

do

       echo$ip

       ./exe.expect$ip 'free;ls /tmp'

done

 

cat ip.list

192.168.153.134

192.168.153.135

192.168.153.136

192.168.153.137
