摘要：準備環境系統下載并解壓啟動啟動啟動創建我修改了默認的端口查看創建的查看的詳細信息測試運行并在控制臺中輸一些消息測試注意需要開兩個終端搭建開發環境生產者

系統

CentOS release 6.6 (Final)

下載并解壓

wget http://mirror.bit.edu.cn/apache/kafka/0.8.0/kafka_2.10-0.8.0.tgz
tar -zxvf kafka_2.10-0.8.0.tgz`

啟動Zookeeper

bin/zookeeper-server-start.sh config/zookeeper.properties &

啟動kafka

bin/kafka-server-start.sh config/server.properties &

創建topic
我修改了默認的端口

bin/kafka-topics.sh --create --zookeeper localhost:2182 --replication-factor 1 --partitions 1 --topic testweixuan &

查看創建的topic

bin/kafka-topics.sh --list --zookeeper localhost:2182

查看topic的詳細信息

bin/kafka-topics.sh --describe --zookeeper localhost:2182

測試producer
運行producer并在控制臺中輸一些消息：

bin/kafka-console-producer.sh --broker-list 192.168.1.116:2182:9092 --topic testweixuan 

測試consumer

bin/kafka-console-consumer.sh --zookeeper 192.168.1.116:2182 --topic testweixuan --from-beginning

注意：需要開兩個終端

kafka.common.FailedToSendMessageException: Failed to send messages after 3 tries.

需要改動config文件夾下的server.properties中的以下兩個屬性

zookeeper.connect=localhost:2181改成zookeeper.connect=192.168.1.116 (自己的服務器IP地址):2181

以及默認注釋掉的 #host.name=localhost 改成 host.name=192.168.1.116 (自己的服務器IP地址)
