系统环境

组件	版本
CentOS	6.5 64x
zookeeper	3.4.5
kafka	2.10-0.8.1.1

单节点安装

下载 kafka 并且解压

tar zxvf kafka_2.10-0.8.1.1.tar.gz 
cd kafka_2.10-0.8.1.1/

启动 kafka 默认配置

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

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

创建 topic 名为“test”

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

# 列出  topic 
./bin/kafka-topics.sh --list --zookeeper localhost:2181

创建客户端

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

创建消费端

bin/kafka-console-consumer.sh --zookeeper localhost:2181 --topic test --from-beginning

集群配置

修改 server-1.properties 中的参数

cp config/server.properties config/server-1.properties

主要修改内容

broker.id=0
log.dirs=/home/Hadoop/development/src/kafka_2.10-0.8.1.1/logs
zookeeper.connect=canbot130:2181,canbot131:2181,canbot132:2181

修改完成后 copy 到其他节点

scp -r ./kafka_2.10-0.8.1.1/ hadoop@canbot131:/home/hadoop/development/src/
scp -r ./kafka_2.10-0.8.1.1/ hadoop@canbot132:/home/hadoop/development/src/

copy 完以后需要修改再修改 server-1.properties 中的 broker.id

broker.id=0 192.169.2.130
broker.id=1 192.169.2.131
broker.id=2 192.169.2.132

启动 Kafka

分别在 canbot130/1/ 2 三个节点都启动

./kafka_2.10-0.8.1.1/bin/kafka-server-start.sh ./kafka_2.10-0.8.1.1/config/server-1.properties &

创建集群 Topic

[hadoop@canbot130 kafka_2.10-0.8.1.1]$./bin/kafka-topics.sh --create --zookeeper canbot130:2181 --replication-factor 3 --partitions 1 --topic test

提示以下内容表示创建 Topic 成功

Created topic "test".

查看 Topic 列表

[hadoop@canbot130 kafka_2.10-0.8.1.1]$ ./bin/kafka-topics.sh --list --zookeeper canbot130:2181
test
[hadoop@canbot130 kafka_2.10-0.8.1.1]$

创建生产者

./bin/kafka-console-consumer.sh --zookeeper canbot130:2181 --topic test

使用该命令创建生产者, 然后将在 canbot132 节点上创建消费者, 查看消息是否被消费

创建消费者

在 canbot132 节点上执行

./bin/kafka-console-consumer.sh --zookeeper canbot130:2181 --topic test

生产消息 ==> 消费消息

在 canbot130 节点上的生产者

[hadoop@canbot130 kafka_2.10-0.8.1.1]$ ./bin/kafka-console-producer.sh --broker-list canbot130:9092 --topic test

在 canbot132 节点上的消费者所产生的信息

错误记录

错误一

java.lang.RuntimeException: A broker is already registered on the path /brokers/ids/1. This probably indicates that you either have configured a brokerid that is already in use, or else you have shutdown this broker and restarted it faster than the zookeeper timeout so it appears to be re-registering.
