    一.Kafka简介

    1>.什么是JMS

      答:在Java中有一个角消息系统的东西,我们叫他Java Message Service,简称JMS。比如各种MQ。

    2>.JMS的两种工作模式

      第一种模式:点到点(point to point,简称P2P),典型的一对一模式(一个人发送数据的同时只有一个人接收数据),也有人称之为端到端(peer to peer)。

      第二种模式:发布订阅模式(publish subscribe,简称P-S),典型的一对多模式(一个人发送数据的同时可以有多个人接收数据)。

    3>.Kafka的工作模式

      答:Kafka的工作模式可以把JMS的两种模式结合在一起,我们称之为消费者组模式

    4>.什么是Kafka

      答:Kafka和flume以及Sqoop一样,他们都是中间件(不含有业务的技术组件)。Kafka在官方定义是分布式消息系统。当然Kafka还可以用在做分布式数据库,除此之外,它还可以当做分布式缓存。

    5>.ApacheKafka是一个分布式流媒体平台

      ApacheKafka是一个分布式流媒体平台,这到底是什么意思呢?接下来我们看一下流媒体平台有三个关键功能如下:

        第一:发布和订阅记录流,类似于消息队列或企业消息传递系统。

        第二:以容错持久的方式存储记录流。

        第三:处理记录发生的流。

    6>.Kafka通常用于两大类应用

      第一:构建可在系统或应用程序之间可靠获取数据的实时流数据管道。

      第二:构建实时流应用程序,用于转换或响应数据流。

    7>.kafka版本介绍

       kafka起先由领英(linkedin创建)公司,开源后被Apache基金会纳入子项目。我们在下载Kafka时,你是如何区分它的版本呢?比如本篇博客下载kafka的版本是“kafka_2.11-1.1.0”,这个“2.11”是scala(java语言脚本化)版本而“1.1.0”是kafka版本。

    二.Kafka本地模式部署

    1>.下载Kafaka

       下载地址:http://kafka.apache.org/downloads。

    2>.解压并创建软连接

    [yinzhengjie@s101 data]$ tar xzf kafka_2.11-1.1.0.tgz -C /soft/
    [yinzhengjie@s101 data]$ ln -s /soft/kafka_2.11-1.1.0/ /soft/kafka
    [yinzhengjie@s101 data]$ 

    4>.配置环境变量并使之生效

    [yinzhengjie@s101 data]$ sudo vi /etc/profile
    [sudo] password for yinzhengjie: 
    [yinzhengjie@s101 data]$ 
    [yinzhengjie@s101 data]$ tail -3 /etc/profile
    #ADD KafKa PATH
    export KAFKA_HOME=/soft/kafka
    PATH=$PATH:$KAFKA_HOME/bin
    [yinzhengjie@s101 data]$ 
    [yinzhengjie@s101 data]$ source /etc/profile
    [yinzhengjie@s101 data]$ 

    5>.修改配置文件

    [yinzhengjie@s101 data]$ sed -i 's@#listeners=PLAINTEXT://:9092@listeners=PLAINTEXT://s101:9092@g' /soft/kafka/config/server.properties
    [yinzhengjie@s101 data]$ sed -i 's@log.dirs=/tmp/kafka-logs@log.dirs=/home/yinzhengjie/kafka/logs@g' /soft/kafka/config/server.properties
    [yinzhengjie@s101 data]$ sed -i 's@zookeeper.connect=localhost:2181@zookeeper.connect=s102:2181,s103:2181,s104:2181@g' /soft/kafka/config/server.properties
    [yinzhengjie@s101 data]$ 

    6>.启动kafka

    [yinzhengjie@s101 data]$ kafka-server-start.sh -daemon /soft/kafka/config/server.properties
    [yinzhengjie@s101 data]$ echo $?
    0
    [yinzhengjie@s101 data]$ jps | grep Kafka
    10145 Kafka
    [yinzhengjie@s101 data]$ netstat -untalp | grep 9092
    (Not all processes could be identified, non-owned process info
     will not be shown, you would have to be root to see it all.)
    tcp6       0      0 172.30.100.101:9092     :::*                    LISTEN      10145/java          
    tcp6       0      0 172.30.100.101:37648    172.30.100.101:9092     ESTABLISHED 10145/java          
    tcp6       0      0 172.30.100.101:9092     172.30.100.101:37642    TIME_WAIT   -                   
    tcp6       0      0 172.30.100.101:37646    172.30.100.101:9092     TIME_WAIT   -                   
    tcp6       0      0 172.30.100.101:9092     172.30.100.101:37648    ESTABLISHED 10145/java          
    [yinzhengjie@s101 data]$ 
    [yinzhengjie@s101 data]$ 

    7>.停止kafka

    [yinzhengjie@s101 data]$ jps | grep Kafka
    10145 Kafka
    [yinzhengjie@s101 data]$ netstat -untalp | grep 9092
    (Not all processes could be identified, non-owned process info
     will not be shown, you would have to be root to see it all.)
    tcp6       0      0 172.30.100.101:9092     :::*                    LISTEN      10145/java          
    tcp6       0      0 172.30.100.101:37648    172.30.100.101:9092     ESTABLISHED 10145/java          
    tcp6       0      0 172.30.100.101:9092     172.30.100.101:37642    TIME_WAIT   -                   
    tcp6       0      0 172.30.100.101:37646    172.30.100.101:9092     TIME_WAIT   -                   
    tcp6       0      0 172.30.100.101:9092     172.30.100.101:37648    ESTABLISHED 10145/java          
    [yinzhengjie@s101 data]$ 
    [yinzhengjie@s101 data]$ 
    [yinzhengjie@s101 data]$ 
    [yinzhengjie@s101 data]$ kafka-server-stop.sh
    [yinzhengjie@s101 data]$ jps | grep Kafka
    [yinzhengjie@s101 data]$ netstat -untalp | grep 9092
    (Not all processes could be identified, non-owned process info
     will not be shown, you would have to be root to see it all.)
    tcp6       0      0 172.30.100.101:37649    172.30.100.101:9092     TIME_WAIT   -                   
    tcp6       0      0 172.30.100.101:9092     172.30.100.101:37648    TIME_WAIT   -                   
    [yinzhengjie@s101 data]$ 
    [yinzhengjie@s101 data]$ 

    三.kafka初体验

    1>.启动kafka(提供服务)

    [yinzhengjie@s101 data]$ kafka-server-start.sh -daemon /soft/kafka/config/server.properties
    [yinzhengjie@s101 data]$ netstat -untalp | grep 9092
    (Not all processes could be identified, non-owned process info
     will not be shown, you would have to be root to see it all.)
    tcp6       0      0 172.30.100.101:9092     :::*                    LISTEN      10516/java          
    tcp6       0      0 172.30.100.101:9092     172.30.100.101:37657    ESTABLISHED 10516/java          
    tcp6       0      0 172.30.100.101:37657    172.30.100.101:9092     ESTABLISHED 10516/java          
    [yinzhengjie@s101 data]$ jps | grep Kafka
    10516 Kafka
    [yinzhengjie@s101 data]$ 
    [yinzhengjie@s101 data]$ kafka-server-start.sh -daemon /soft/kafka/config/server.properties

    2>.创建主题(消息保管者

    [yinzhengjie@s101 data]$ kafka-topics.sh --zookeeper s102:2181 --create  --partitions 2 --replication-factor 1  --topic yinzhengjie
    Created topic "yinzhengjie".
    [yinzhengjie@s101 data]$ 
    [yinzhengjie@s101 data]$ kafka-topics.sh --zookeeper s102:2181 --create --partitions 2 --replication-factor 1 --topic yinzhengjie

    3>.启动生产者(消息发送方

    [yinzhengjie@s101 data]$ kafka-console-producer.sh --broker-list s101:9092 --topic yinzhengjie
    >My name is yinzhengjie , I love Beijing!   
    >
    [yinzhengjie@s101 data]$ kafka-console-producer.sh --broker-list s101:9092 --topic yinzhengjie

    4>.启动消费者(消息接收方

    [yinzhengjie@s101 lib]$ kafka-console-consumer.sh --zookeeper s102:2181 --topic yinzhengjie --from-beginning
    Using the ConsoleConsumer with old consumer is deprecated and will be removed in a future major release. Consider using the new consumer by passing [bootstrap-server] instead of [zookeeper].
    My name is yinzhengjie , I love Beijing!
    [yinzhengjie@s101 lib]$ kafka-console-consumer.sh --zookeeper s102:2181 --topic yinzhengjie --from-beginning
