start zookeeper and kafka in the background and create a topic

kafka_start.sh

#!/bin/bash

if [ "$#" -ne 1 ]; then
  echo "Please supply topic name"
  exit 1
fi

nohup bin/zookeeper-server-start.sh -daemon config/zookeeper.properties > /dev/null 2>&1 &
sleep 2
nohup bin/kafka-server-start.sh -daemon config/server.properties > /dev/null 2>&1 &
sleep 2

bin/kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic $1
bin/kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic parsed

Hi, while I tried your script I got the following error:
WARN Session 0x0 for server null, unexpected error, closing socket connection and attempting to reconnect (org.apache.zookeeper.ClientCnxn)
java.net.ConnectException: Connection refused

any help on this, please?

Use "-daemon" instead

#!/bin/bash
$KAFKA_HOME/bin/zookeeper-server-start.sh -daemon config/zookeeper.properties
$KAFKA_HOME/bin/kafka-server-start.sh -daemon config/server.properties

Thanks, updated.

@khanhafizurrahman32 I know this is over two years later, but for anyone else with the issue...firewall could be blocking it
