Step 4: Send some messages

Step 4: 发送消息

　　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.

Kafka提供了一个命令行的工具，可以从输入文件或者命令行中读取消息并发送给Kafka集群。每一行是一条消息。

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

运行producer（生产者）,然后在控制台输入几条消息到服务器。

> bin/kafka-console-producer.sh --broker-list localhost:9092 --topic test
