同步文件夹

每个服务器都要安装rsync

yum install rsync

在/usr/local/bin创建文件xsync

#!/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 node2 node3 node4
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
