[root@garytao-01 shell]# vi 4.expect
增加如下脚本内容:

#如果机器上没有安装rsync请使用如下命令安装
[root@garytao-02 ~]# yum -y install rsync
[root@garytao-01 shell]# vi 5.expect
增加如下内容:

set passwd "123456"
set host [lindex $argv 0]
set file [lindex $argv 1]
spawn rsync -av $file root@$host:$file

对于大公司而言,肯定时不时会有网站或者配置文件更新,而且使用的机器肯定也是好多台,少则几台,多则几十甚至上百台。所以,自动同步文件是至关重要的。
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。
rsync -av --files-from=list.txt??/??root@host:/
## 创建rsync.expect执行脚本
[root@garytao-01 shell]# vi rsync.expect
增加如下脚本内容:
#!/usr/bin/expect
set passwd "123456"
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
## file.list内容,为同步的文件路径列表
[root@garytao-01 shell]# vi /tmp/file.list
增加如下需要同步的文件路径:
/tmp/12.txt
/root/shell/1.sh
/root/111/222/lll.txt
## ip.list内容,为需要同步的远程机器IP列表
[root@garytao-01 shell]# vi /tmp/ip.list
172.16.111.110
127.0.0.1
##创建一个rsync.sh脚本
[root@garytao-01 shell]# vi rsync.sh
#!/bin/bash
for ip in `cat /tmp/ip.list`
do
./rsync.expect $ip /tmp/file.list
done
##加权限执行脚本
[root@garytao-01 shell]# chmod a+x rsync.expect
[root@garytao-01 shell]# sh -x rsync.sh
++ cat /tmp/ip.list
+ for ip in ‘`cat /tmp/ip.list`‘
+ ./rsync.expect 172.16.111.110 /tmp/file.list

备注:如果不能保证对方机器有相同的路径就加上R,编辑rsync.expect
注意:做分发系统expect脚本的前提是需要保证机器密码一样,这样会有一个问题就是如果密码泄露的话就会有安全隐患,所以可以做密钥认证增加安全。
[root@garytao-01 shell]# passwd
更改用户 root 的密码 。
新的 密码:
重新输入新的 密码:

[root@garytao-01 shell]# chmod a+x exe.expect
## 定义一个exe的sehll脚本
[root@garytao-01 shell]# vim exe.sh
增加如下脚本内容:
#!/bin/bash
for ip in `cat /tmp/ip.list`
do
./exe.expect $ip "hostname"
done
##执行脚本
[root@garytao-01 shell]# sh exe.sh
