文件分發(fā)系統(tǒng)

一個(gè)機(jī)器上的多個(gè)文件要同步到多臺(tái)機(jī)器上，該如何處理？

需求：將192.168.221.10機(jī)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這兩臺(tái)機(jī)器上

• 在192.168.221.10機(jī)器上創(chuàng)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

• 實(shí)現(xiàn)文件同步的腳本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 / $user@$host:/ expect { "yes/no" {send "yes\r";exp_continue} "password:" {send "$passwd\r"} } expect eofchmod +x /usr/local/sbin/expect/one-more-rsync.sh

• 建立一個(gè)同步的文件列表(one-more-rsync.sh中變量file)

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

• 建立一個(gè)發(fā)送文件目標(biāo)機(jī)器的ip列表

vim /tmp/desip.txt 192.168.221.20 192.168.221.30

• 寫(xiě)一個(gè)運(yùn)行的腳本run.sh,調(diào)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 //注意參數(shù)的順序 done

• 執(zhí)行run.sh

[root@localhost expect]# bash run.sh spawn rsync -avR --files-from=/tmp/publicfilelist.txt / root@192.168.221.20:/ root@192.168.221.20's password: building file list ... done aa/ aa/aa.txt bb/ bb/bb.txt cc/ cc/cc.txt dd/ dd/dd.txtsent 328 bytes received 100 bytes 856.00 bytes/sec total size is 12 speedup is 0.03 spawn rsync -avR --files-from=/tmp/publicfilelist.txt / root@192.168.221.30:/ The authenticity of host '192.168.221.30 (192.168.221.30)' can't be established.

總結(jié)：

• 目標(biāo)機(jī)器的用戶(hù)名與密碼都是一樣的(192.168.221.20與192.168.221.30這兩臺(tái)機(jī)器的用戶(hù)名與密碼都是一樣的)
• rsync -R
• bash腳本中調(diào)用了expect腳本(如 ./one-more-rsync.sh,最好用絕對(duì)路徑,我這兒run.sh與one-more-rsync.sh在同一目錄下)
• 參數(shù)的對(duì)應(yīng)關(guān)系
