expect脚本同步文件

[[email protected] shell]# vi 1.expect 

#!/usr/bin/expect
set passwd "123456"
spawn rsync -av [email protected]:/tmp/12.txt /tmp/
expect {
"yes/no" { send "yes\r"}
"password:" { send "$passwd\r" }
}
expect eof

[[email protected] shell]# chmod +x 1.expect

执行：

说明： expect eof的作用是等待脚本中的命令执行完后再退出。

expect脚本指定host和要同步的文件

[[email protected] shell]# vi 2.expect 

#!/usr/bin/expect
set passwd "123456"
set host [lindex $argv 0]
set file [lindex $argv 1]
spawn rsync -av $file [email protected]$host:$file
expect {
"yes/no" { send "yes\r"}
"password:" { send "$passwd\r" }
}
expect eof

[[email protected] shell]# chmod a+x 2.expect 
[[email protected] shell]# touch /tmp/3.txt
[[email protected] shell]# ./2.expect 192.168.1.83 "/tmp/3.txt"
spawn rsync -av /tmp/3.txt [email protected]:/tmp/3.txt
[email protected]‘s password: 
sending incremental file list
3.txt

注： 本脚本只能同步一个文件。

构建文件分发系统

首先要有一台模板机器，把要分发的文件准备好，然后只要使用expect脚本批量把需要同步的文件分发到目标机器即可（把多个文件分发到多台机器时需要创建文件、IP列表，即本文中的list.txt、iplist.txt）。
创建 分发系统
创建一个文件列表文件备用：

[[email protected] ~]# vim /tmp/list.txt

/tmp/12.txt
/tmp/3.txt
#该文件下可以添加多个文件

注意：此处要保证客户端有同样的目录。

创建一个IP列表文件备用：

[[email protected] ~]# vim /tmp/iplist.txt

192.168.1.83
#该文件下可以指定多个IP
创建rsync.expect脚本：
[[email protected] ~]# vim rsync.expect

#!/usr/bin/expect
set passwd "123456"
set host [lindex $argv 0]
set file [lindex $argv 1]
spawn rsync -avR --files-from=$file / [email protected]$host:/
expect {
"yes/no" { send "yes\r"}
"password:" { send "$passwd\r" }
}
#expect eof

[[email protected] ~]# chmod a+x rsync.expect
[[email protected] ~]# vim rsync.sh

#!/bin/bash
for ip in `cat /tmp/iplist.txt`
do
    ./rsync.expect $ip /tmp/list.txt
done

执行：
sh -x rsync.sh
++ cat /tmp/iplist.txt
+ for ip in ‘`cat /tmp/iplist.txt`‘
+ ./rsync.expect 192.168.1.48 /tmp/list.txt
spawn rsync -avR --files-from=/tmp/list.txt / [email protected]:/
building file list ... done
tmp/

批量远程执行命令

创建exe.expect
[[email protected] ~]# vim exe.expect

#!/usr/bin/expect
set host [lindex $argv 0]
set passwd "123456"
set cm [lindex $argv 1]
spawn ssh [email protected]$host
expect {
"yes/no" { send "yes\r"}
"password:" { send "$passwd\r" }
}
expect "]*"
send "$cm\r"
expect "]*"
send "exit\r"

[[email protected] ~]# chmod a+x exe.expect

[[email protected] ~]# vim exe.sh

#!/bin/bash
for ip in `cat /tmp/iplist.txt`
do
  ./exe.expect $ip "hostname"
done

执行：
sh exe.sh
