1.环境说明

主机信息如下:

 
    
  
[root@test1 soft]# hostname
test1
[root@test1 soft]# cat /etc/hosts
127.0.0.1  localhost localhost.localdomain localhost4 localhost4.localdomain4
::1     localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.56.91 test1 
192.168.56.92 test2 
192.168.56.93 test3 
192.168.56.1  PC-201306171517

操作系统版本如下:

 
[root@test1 soft]# cat /etc/redhat-release 
CentOS release 6.4 (Final)
[root@test1 soft]# uname -a
Linux test1 2.6.32-358.el6.x86_64 #1 SMP Fri Feb 22 00:31:26 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

2.下载kafka

下载地址如下:

http://kafka.apache.org/downloads

我这里使用 Scala 2.11 - kafka_2.11-0.10.0.1.tgz ( asc , md5 )版本

3.安装配置kafka

一.解压缩kafka

 
[root@test1 soft]# tar zxvf kafka_2.11-0.10.0.1.tgz -C /root/kafka

二.配置zookeeper

由于kafka需要使用到zookeeper来注册信息,因此需要首先配置zookeeper.在kafka的安装包中已经提供了zookeeper,不需要额外安装,直接配置一下即可.配置文件在config下的zookeeper. properties

 
     
   
 
        
 
         
[root@test1 config]# cat zookeeper.properties

# the directory where the snapshot is stored.
dataDir=/root/kafka/kafka_2.11-0.10.0.1/zoodata            ###########这里修改zookeeper的快照目录,需要事先在文件系统上创建目录,其它默认即可.
# the port at which the clients will connect
clientPort=2181 #默认端口号2181
# disable the per-ip limit on the number of connections since this is a non-production config
maxClientCnxns=0

三.配置kafka

kafka的配置文件在config下的server.properties文件.下面是一个配置实例:

[root@test1 config]# pwd
/root/kafka/kafka_2.11-0.10.0.1/config
[root@test1 config]# cat server.properties 
# Licensed to the Apache Software Foundation (ASF) under one or more
# contributor license agreements. See the NOTICE file distributed with

# distributed under the License is distributed on an "AS IS" BASIS,
# WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND,either express or implied.

# see kafka.server.KafkaConfig for additional details and defaults
############################# Server Basics #############################
# The id of the broker. This must be set to a unique integer for each broker.
broker.id=0                                          ############################这里是主机的id,类似于zookeeper的id
############################# Socket Server Settings #############################
# The address the socket server listens on. It will get the value returned from 
# java.net.InetAddress.getCanonicalHostName() if not configured.
#  FORMAT:
#   listeners = security_protocol://host_name:port
#  EXAMPLE:
#   listeners = PLAINTEXT://your.host.name:9092
#listeners=PLAINTEXT://:9092
# Hostname and port the broker will advertise to producers and consumers. If not set,153); white-space: nowrap; position: absolute; cursor: default; z-index: 4; Box-sizing: content-Box; left: 0px; width: 23px;">
            36 
          
# it uses the value for "listeners" if configured. Otherwise,it will use the value
# returned from java.net.InetAddress.getCanonicalHostName().
#advertised.listeners=PLAINTEXT://your.host.name:9092                     ###########默认的端口是9092,如果需要修改端口,需要添加port参数port=9093.再将advertised.listeners同时修改
# The number of threads handling network requests
num.network.threads=3
# The number of threads doing disk I/O
num.io8
# The send buffer (SO_SNDBUF) used by the socket server
socket.send.buffer.bytes=102400
# The receive buffer (SO_RCVBUF) used by the socket server
socket.receive.buffer
            51 
          

# The maximum size of a request that the socket server will accept (protection against OOM)

socket.request.max104857600

############################# Log Basics #############################

# A comma seperated list of directories under which to store log files

log.dirs=/root/kafka/kafka_2.11-0.10.0.1/logs                         ####################################这里是kafka的log目录,根据需要修改.

# The default number of log partitions per topic. More partitions allow greater

# parallelism for consumption,but this will also result in more files across

# the brokers.

num.partitions=1

# The number of threads per data directory to be used for log recovery at startup and flushing at shutdown.

# This value is recommended to be increased for installations with data dirs located in RAID array.

num.recovery.threads.per.data.dir=
            69

4.启动kafka

为了方便可以将kafka的运行目录添加到PATH环境变量中.

首先使用命令 bin/zookeeper-server-start.sh config/zookeeper.properties
启动zookeeper.

5.模拟测试kafka发布订阅

新建一个窗口模拟producer,执行:

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

然后在窗口中随便输入

 
[root@test1 kafka]# kafka-console-producer.sh --broker-list localhost:9092 --topic test
aaaa
bbbb

在另外一个窗口中模拟consumer,执行:

[root@test1 ~]# kafka-console-consumer.sh --zookeeper localhost:2181 --topic test1 --from-beginning

然后会发现producer的输入会实时的发布到consumer中

 
[root@test1 ~]# kafka-console-consumer.sh --zookeeper localhost:2181 --topic test1 --from-beginning
aaaa
bbbb

创建主题:

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

查看主题:

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