文件分发系统

一个机器上的多个文件要同步到多台机器上，该如何处理？

需求：将192.168.221.10机器上的/aa/aa.txt、/bb/bb.txt、/cc/cc.txt、/dd/dd.txt同步到192.168.221.20，192.168.221.30这两台机器上

• 在192.168.221.10机器上创建aa/aa.txt、/bb/bb.txt、/cc/cc.txt、/dd/dd.txt

mkdir {/aa/,/bb/,/cc/,/dd/}
echo "aa" > /aa/aa.txt;echo "bb" > /bb/bb.txt;echo "cc" > /cc/cc.txt;echo "dd" > /dd/dd.txt

• 实现文件同步的脚本one-more-rsync.sh

vim /usr/local/sbin/expect/one-more-rsync.sh
#!/usr/bin/expect
set passwd "root"
set user "root"
set host [lindex $argv 0]
set file [lindex $argv 1]
spawn rsync -avR --files-from=$file / [email protected]$host:/
expect {
"yes/no" {send "yes\r";exp_continue}
"password:" {send "$passwd\r"}
}
expect eof

chmod +x /usr/local/sbin/expect/one-more-rsync.sh

• 建立一个同步的文件列表(one-more-rsync.sh中变量file)

vim /tmp/publicfilelist.txt
/aa/aa.txt
/bb/bb.txt
/cc/cc.txt
/dd/dd.txt

• 建立一个发送文件目标机器的ip列表

vim /tmp/desip.txt
192.168.221.20
192.168.221.30

• 写一个运行的脚本run.sh,调用one-more-rsync.sh

vim /usr/local/sbin/expect/run.sh
#!/bin/bash
publicfilelist="/tmp/publicfilelist.txt"
for desip in `cat /tmp/desip.txt`; do
        ./one-more-rsync.sh $desip $publicfilelist   //注意参数的顺序
done

• 执行run.sh

[[email protected] expect]# bash run.sh 
spawn rsync -avR --files-from=/tmp/publicfilelist.txt / [email protected]:/
