This article is about how to install and implement stand-alone testing of kafka. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

1.3 Quick Start

This tutorial assumes you are starting fresh and have no existing Kafka or ZooKeeper data.

Step 1: Download the code

Download the 0.10.0.0 release and un-tar it.

> tar-xzf kafka_2.11-0.10.0.0.tgz > cd kafka_2.11-0.10.0.0Step 2: Start the server

Kafka uses ZooKeeper so you need to first start a ZooKeeper server if you don't already have one. You can use the convenience script packaged with kafka to get a quick-and-dirty single-node ZooKeeper instance.

> bin/zookeeper-server-start.sh config/zookeeper.properties [2013-04-22 15 config/zookeeper.properties 01 config/zookeeper.properties 37495] INFO Reading configuration from: (org.apache.zookeeper.server.quorum.QuorumPeerConfig).

Now start the Kafka server:

> bin/kafka-server-start.sh config/server.properties [2013-04-22 15 kafka.utils.VerifiableProperties 01purl 47028] INFO Verifying properties (kafka.utils.VerifiableProperties) [2013-04-22 15 kafka.utils.VerifiableProperties 01purl 47051] INFO Property socket.send.buffer.bytes is overridden to 1048576 (kafka.utils.VerifiableProperties)... Step 3: Create a topic

Let's create a topic named "test" with a single partition and only one replica:

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

We can now see that topic if we run the list topic command:

> bin/kafka-topics.sh-list-zookeeper localhost:2181test

Alternatively, instead of manually creating topics you can also configure your brokers to auto-create topics when a non-existent topic is published to.

Step 4: Send some messages

Kafka comes with a command line client that will take input from a file or from standard input and send it out as messages to the Kafka cluster. By default each line will be sent as a separate message.

Run the producer and then type a few messages into the console to send to the server.

> bin/kafka-console-producer.sh-- broker-list localhost:9092-- topic testThis is a messageThis is another messageStep 5: Start a consumer

Kafka also has a command line consumer that will dump out messages to standard output.

> bin/kafka-console-consumer.sh-zookeeper localhost:2181-topic test-from-beginningThis is a messageThis is another message

It's easy to use.
