                fname=$(basename $file)
                ssh $host "mkdir -p $pdir"
                rsync -av $pdir/$fname $host:$pdir
            else

        ssh $host jps 
done

3. Zookeeper启动脚本

	for i in hadoop102 hadoop103 hadoop104
	do
		echo  ------------- zookeeper $i 启动 ------------
		ssh $i "/opt/module/zookeeper-3.5.7/bin/zkServer.sh start"

"status"){
	for i in hadoop102 hadoop103 hadoop104
	do
		echo  ------------- zookeeper $i 状态 ------------
		ssh $i "/opt/module/zookeeper-3.5.7/bin/zkServer.sh status"
