一、xcall脚本

在cd /usr/local/bin/路径下创建xcall

vim /usr/local/bin/xcall 

#!/bin/bash
for host in hadoop100 hadoop101 hadoop102
do
        echo =============== $host ===============
        ssh $host jps
done                                                                                                                                          

授权

chmod 777 /usr/local/bin/xcall 

效果

二、xsync

三个节点都安装

yum install rsync -y

vim /usr/local/bin/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 hadoop100 hadoop101 hadoop102
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

授权

chmod 777 /usr/local/bin/xsync 

测试

xsync xcall 

如果需要密码可以配置免密，可参考
