1下載並安裝JDK

參考jdk的安裝，需要jdk1.6+。

2 Kafka的安裝

2.1 下載kafka

下載地址：http://mirrors.hust.edu.cn/apache/kafka/0.10.0.1/kafka_2.11-0.10.0.1.tgz

2.2 解壓安裝包

$ tar zvxf kafka_2.11-0.10.0.1.tgz

2.3 複製解壓後的文件夾到安裝目錄

$ cp -r kafka_2.11-0.10.0.1 /software/

2.4 創建kafka安裝目錄的軟鏈接

$ ln -s /software/kafka_2.11-0.10.0.1/software/kafka

2.5 配置環節變量

修改/etc/profile文件內容：

export KAFKA_HOME=/software/kafka

export PATH=$KAFKA_HOME/bin:$FLUME_HOME/bin:$ZOOKEEPER_HOME/bin:$HBASE_HOME/bin:

$HIVE_HOME/bin:$JAVA_HOME/bin:$HADOOP_HOME/bin:$HADOOP_HOME/sbin:$PATH

export CLASSPATH=.:$KAFKA_HOME/libs/*:$FLUME_HOME/lib/*:$HBASE_HOME/lib/*:$JAVA_

HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

2.6 啓動kafka

1）、啓動kafka前要先啓動zookeeper

$ zookeeper-server-start.sh/software/kafka/config/zookeeper.properties &

2）、啓動kafka

$ kafka-server-start.sh/software/kafka/config/server.properties &

3 體驗單節點Kafka

3.1 創建topic

$ kafka-topics.sh --create --zookeeperlocalhost:2181 --replication-factor 1 --partitions 1 --topic test

查詢創建的topic

$ kafka-topics.sh --list --zookeeperlocalhost:2181

3.2 發送消息

$ kafka-console-producer.sh --broker-listlocalhost:9092 --topic test

This is a message

This is another message

3.3 消費消息

$ kafka-console-consumer.sh --bootstrap-serverlocalhost:9092 --zookeeper localhost:2181 --topic test --from-beginning

This is a message

This is another message

4 搭建多broker的Kafka集羣

4.1 複製配置文件

$ cd /software/kafka/config/

$ cp server.properties s1.properties

$ cp server.properties s2.properties

$ cp server.properties s3.properties

4.2 修改配置文件

config/s1.properties:

broker.id=1

listeners=PLAINTEXT://:9093

log.dir=/tmp/kafka-logs-1

config/s2.properties:

broker.id=2

listeners=PLAINTEXT://:9094

log.dir=/tmp/kafka-logs-2

config/s3.properties:

broker.id=3

listeners=PLAINTEXT://:9095

log.dir=/tmp/kafka-logs-3

4.3 啓動kafka

$ kafka-server-start.sh/software/kafka/config/s1.properties &

$ kafka-server-start.sh/software/kafka/config/s2.properties &

$ kafka-server-start.sh /software/kafka/config/s3.properties&

4.4 創建topic

$ kafka-topics.sh --create--zookeeper localhost:2181 --replication-factor 3 --partitions 1 --topicmy-replicated-topic

查看topic描述

$ kafka-topics.sh --describe --zookeeper localhost:2181 --topicmy-replicated-topic

4.5 發送消息

$ kafka-console-producer.sh --broker-listlocalhost:9093 --topic my-replicated-topic

my test msg 1

my test msg 2

my test msg 3

4.6 消費消息

$ kafka-console-consumer.sh--zookeeper localhost:2181 --from-beginning --topic my-replicated-topic

5 容錯測試

5.1 找到s1進程

$ ps -ef| grep s1.properties

5.2 殺死進程s1

kill pid

5.3 查看主題描述

$>kafka-topics.sh --describe --zookeeperlocalhost:2181 --topic my-replicated-topic

Topic:my-replicated-topic PartitionCount:1 ReplicationFactor:3 Configs:

Topic: my-replicated-topic Partition: 0 Leader: 2 Replicas:1,2,0 Isr: 2,0

5.4 啓動消費者消費主題消息

$>kafka-console-consumer.sh--zookeeper localhost:2181 --from-beginning --topic my-replicated-topic

        my test message 1

        my test message 2

6 完全分佈式搭建

6.1 將kafka安裝文件夾分發到其餘集羣服務器

$ xsync kafka_2.11-0.10.0.1/

$ xsync kafka

6.2 分發環境變量

#xsync /etc/profile

6.3 修改server.properties屬性文件並分發

broker.id=203 #修改broker的id

log.dirs=/home/hadoop/kafka/logs #修改日誌的存放路徑

zookeeper.connect=s201:2181,s202:2181,s203:2181 #修改zookeeper的連接路徑

6.4 啓動Kafka集羣

到部署kafka每臺服務器上面啓動kafka集羣
