寒假学习13-Linux xsync命令脚本

使用xsync脚本循环同步文件到各个目标节点的相同目录下（需要用户具有root权限或者直接使用root用户创建xsync）
1.sudo创建xsync文件（root用户可直接创建）

xsync脚本源码：

#!/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 node1 node2
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

yum install -y rsync

给xsync文件赋予执行权限：

chmod  777 xsync

• 注意：
• 1.确保各个节点都安装了rsync工具并启动

如：将 master机器/opt下的scp复制到  node1  node2
