linux下一键起zookeeper和hadoop集群

最近经常频繁的启动和关闭hadoop集群，每次都要操作几台机器，太烦了，因为写了一个文件一键开启和关闭集群。
首先创建了一个demo.sh 文件，修改文件的权限，能够让文件可以被执行。
文件中的内容为：

#!/bin/bash
for i in {
    
    "vbserver","vbserver01","vbserver02","vbserver03"};
do
        echo "-----$1 $i zookeeper-------"
        ssh $i "source /etc/profile;/opt/bigdata/hadoop/zookeeper345/bin/zkServer.sh $1"
done
sleep 5
for j in {
    
    "vbserver","vbserver01","vbserver02","vbserver03"};
do
        echo "------$j status-------"
        ssh $j "source /etc/profile;/opt/bigdata/hadoop/zookeeper345/bin/zkServer.sh status"
done
sleep 5
var='-all.sh'
var1=$1$var
sleep 3
echo "----- hadoop $1-----"
ssh vbserver "sh /opt/bigdata/hadoop/hadoop260/sbin/$var1"
echo "------yarn-daemon resourcemanager"
ssh vbserver01 "sh /opt/bigdata/hadoop/hadoop260/sbin/yarn-daemon.sh $1 resourcemanager"

想要开启或者关闭zookeeper和hadoop时

./demo.sh start
或者
./demo.sh stop
