Zookeeper of shell batch startup script

@zookeeper batch startup script

#! /bin/bash
node='master slave1 slave2'
zkServerPath="/opt/zookeeper-3.4.10/bin/zkServer.sh"

case $1 in
"start"){
    
    
	for i in $node
	do
		ssh $i "$zkServerPath start"
	done
};;
"stop"){
    
    
	for i in $node
	do
		ssh $i "$zkServerPath stop"
	done
};;
"status"){
    
    
	for i in $node
	do
		ssh $i "$zkServerPath status"
	done
};;
esac

Remarks: The premise is that the machines can log in without secret, write the parameter start/stop/status after the script name when starting
