Linux不同服务器之间文件同步脚本

#!/bin/bash

#1. 判断参数个数 
if [ $# -lt 1 ] 
then  
	echo Not Enough Arguement!  
	exit; 
fi
#2. 遍历集群所有机器 
for host in master slave1 slave2 
do  
	echo ==================== $host ====================  
	#3. 遍历所有目录，挨个发送   
	for file in $@  
	do  
		#4. 判断文件是否存在  
		if [ -e $file ]  
			then  
				#5. 获取父目录  
				pdir=$(cd -P $(dirname $file); pwd)   
				#6. 获取当前文件的名称  
				fname=$(basename $file)  
				ssh $host "mkdir -p $pdir"  
				rsync -av $pdir/$fname $host:$pdir  
			else  
				echo $file does not exists!  
		fi  
	done 	
done 

1、复制脚本到 /bin 目录

2、为脚本添加执行权限

chmod +x xsync

3、测试脚本

>>（1） 将master服务器中根目录的test文件同步到 目标服务器的相同目录下

[root@master ~]# xsync test.txt
==================== master ====================
