批量启动zookeeper

#zookeeper install path
#path="/export/servers/zookeeper-3.6.2/bin"

# get parameters start | status | stop
case $@ in 
start)
#---------start-zookeeper-----------
  for ip in ${iparray[*]}
    do
        #echo "ssh to $ip"
        ssh $ip "source /etc/profile;zkServer.sh start"
        sleep 2s
  done
  exit
