創建同步腳本xsync

mkdir -p /home/hadoop/bin && cd /home/hadoop/bin
vim xsync

#!/bin/bash#1. 判斷參數個數
if [ $# -lt 1 ]
thenecho Not Arguementexit;
fi#2. 遍歷集群所有機器
for host in node1 node2 node3
doecho ====================  $host  ====================#3. 遍歷所有目錄，挨個發送for file in $@do#4. 判斷文件是否存在if [ -e $file ]then#5. 獲取父目錄pdir=$(cd -P $(dirname $file); pwd)#6. 獲取當前文件的名稱fname=$(basename $file)ssh $host "mkdir -p $pdir"rsync -av $pdir/$fname $host:$pdirelseecho $file does not exists!fidone
done

chmod +x xsync.sh

創建jps狀態打印

vim /export/server/hadoop/sbin/jpsall.sh

#!/bin/bash
for host in node1 node2 node3
doecho =============== $host ===============ssh $host $JAVA_HOME/bin/jps
done

chmod +x jpsall.sh

hadoop啟動腳本
