Shell腳本實現線上服務器之間對比文件是否一致

更新時間：2014年12月27日 11:43:53 投稿：junjie

這篇文章主要介紹了Shell腳本實現線上服務器之間對比文件是否一致,本文腳本在特殊環(huán)境下使用,需要的朋友可以參考下

工作中有時需要對比文件是否一致，通過以下腳本可以實現(比較簡單)：分享出來，希望能幫助到有同樣需求的朋友~

#!/bin/bash

#對比服務器上文件是否一樣

# Richard shen 2012/07/08

LC_ALL='en_US.UTF-8'

basedir=`dirname $0`

HOST=$basedir/host.txt

PASSWD="abcd"   #密碼

FILE=$basedir/file.txt   

LOG=$basedir/tmp.log

>$LOG

[ ! -f /usr/bin/nc ] && yum -y install nc

[ ! -f /usr/bin/expect ] && yum -y install expect

auto_smart_ssh () {

    expect -c "set timeout -1;

        spawn ssh -o StrictHostKeyChecking=no $2 ${@:3};

                 expect {

                         *assword:* {send -- $1\r;

                         expect {

                             *denied* {exit 2;}

                             eof

                                }

                         }

                  eof     {exit 1;}

                  }

                                  "

 #   return $?

 }

num=0

for file in `cat $FILE`;do

   for host in `cat $HOST`;do

       [[ $host =~ "^#" ]] && continue

       let 'num++'

       if ! /usr/bin/nc -w 1 $host 22 > /dev/null; then

          echo " ssh connect failed." | tee -a $LOG

          continue

       else

          echo -e "\e[32m$host ($FILE) MD5 compared files...\e[0m"

          auto_smart_ssh $PASSWD root@$host md5sum $file | grep $file | grep -v StrictHostKeyChecking | tee -a $LOG

      fi

    done

echo "----------------------------------------------------------"

done

對比的IP地址寫入host.txt，需要對比的文件(支持多個文件)寫入file.txt
輸出結果為:

復制代碼代碼如下:

192.168.113.108 (./file.txt) MD5 compared files...
