一:前提

1.安装条件

  Java   Scala

  zookeeper

  Kafka

 

2.使用版本

  使用的版本是0.8.2.1

二:伪分布式安装

1.解压

  kafka_2.10-0.8.2.1

 

2.拷贝server.properties

3.依次修改四个文件

  官网上:说明这三个配置项是必要的。

  主要要配置的有:

    broker.id=0 :服务器唯一标识

    port=9092   :服务器监听端口

    host.name=linux-hadoop01.ibeifeng.com  : 服务器监听主机名

    log.dirs=/opt/modules/kafka_2.10-0.8.2.1/data/0  :kafka数据存储路径

    zookeeper.connect=linux-hadoop01.ibeifeng.com:2181/kafka   :元数据管理的zookeeper的配置信息

  需要修改四个文件,这里只写第一个。

 17 ############################# Server Basics #############################
 18 
 19 # The id of the broker. This must be set to a unique integer for each broker.
 20 broker.id=0
 21 
 22 ############################# Socket Server Settings #############################
 23 
 24 # The port the socket server listens on
 25 port=9092
 26 
 27 # Hostname the broker will bind to. If not set, the server will bind to all interfaces
 28 host.name=linux-hadoop01.ibeifeng.com
 29 
 30 # Hostname the broker will advertise to producers and consumers. If not set, it uses the
 31 # value for "host.name" if configured.  Otherwise, it will use the value returned from
 32 # java.net.InetAddress.getCanonicalHostName().
 33 #advertised.host.name=<hostname routable by clients>
 34 
 35 # The port to publish to ZooKeeper for clients to use. If this is not set,
 36 # it will publish the same port that the broker binds to.
 37 #advertised.port=<port accessible by clients>
 38 
 39 # The number of threads handling network requests
 40 num.network.threads=3
 41  
 42 # The number of threads doing disk I/O
 43 num.io.threads=8
 44 
 45 # The send buffer (SO_SNDBUF) used by the socket server
 46 socket.send.buffer.bytes=102400
 47 
 48 # The receive buffer (SO_RCVBUF) used by the socket server
 49 socket.receive.buffer.bytes=102400
 50 
 51 # The maximum size of a request that the socket server will accept (protection against OOM)
 52 socket.request.max.bytes=104857600
 53 
 54 
 55 ############################# Log Basics #############################
 56 
 57 # A comma seperated list of directories under which to store log files
 58 log.dirs=/opt/modules/kafka_2.10-0.8.2.1/data/0
 59 
 60 # The default number of log partitions per topic. More partitions allow greater
 61 # parallelism for consumption, but this will also result in more files across
 62 # the brokers.
 63 num.partitions=1
 64 
 65 # The number of threads per data directory to be used for log recovery at startup and flushing at shutdown.
 66 # This value is recommended to be increased for installations with data dirs located in RAID array.
 67 num.recovery.threads.per.data.dir=1
 68 
 69 ############################# Log Flush Policy #############################
 70 
 71 # Messages are immediately written to the filesystem but by default we only fsync() to sync
 72 # the OS cache lazily. The following configurations control the flush of data to disk. 
 73 # There are a few important trade-offs here:
 74 #    1. Durability: Unflushed data may be lost if you are not using replication.
 75 #    2. Latency: Very large flush intervals may lead to latency spikes when the flush does occur as there will be a lot of data to flush.
 76 #    3. Throughput: The flush is generally the most expensive operation, and a small flush interval may lead to exceessive seeks. 
 77 # The settings below allow one to configure the flush policy to flush data after a period of time or
 78 # every N messages (or both). This can be done globally and overridden on a per-topic basis.
 79 
 80 # The number of messages to accept before forcing a flush of data to disk
 81 #log.flush.interval.messages=10000
 82 
 83 # The maximum amount of time a message can sit in a log before we force a flush
 84 #log.flush.interval.ms=1000
 85 
 86 ############################# Log Retention Policy #############################
 87 
 88 # The following configurations control the disposal of log segments. The policy can
 89 # be set to delete segments after a period of time, or after a given size has accumulated.
 90 # A segment will be deleted whenever *either* of these criteria are met. Deletion always happens
 91 # from the end of the log.
 92 
 93 # The minimum age of a log file to be eligible for deletion
 94 log.retention.hours=168
 95 
 96 # A size-based retention policy for logs. Segments are pruned from the log as long as the remaining
 97 # segments don‘t drop below log.retention.bytes.
 98 #log.retention.bytes=1073741824
 99 
100 # The maximum size of a log segment file. When this size is reached a new log segment will be created.
101 log.segment.bytes=1073741824
102 
103 # The interval at which log segments are checked to see if they can be deleted according 
104 # to the retention policies
105 log.retention.check.interval.ms=300000
106 
107 # By default the log cleaner is disabled and the log retention policy will default to just delete segments after their retention expires.
108 # If log.cleaner.enable=true is set the cleaner will be enabled and individual logs can then be marked for log compaction.
109 log.cleaner.enable=false
110 
111 ############################# Zookeeper #############################
112 
113 # Zookeeper connection string (see zookeeper docs for details).
114 # This is a comma separated host:port pairs, each corresponding to a zk
115 # server. e.g. "127.0.0.1:3000,127.0.0.1:3001,127.0.0.1:3002".
116 # You can also append an optional chroot string to the urls to specify the
117 # root directory for all kafka znodes.
118 zookeeper.connect=linux-hadoop01.ibeifeng.com:2181/kafka
119 
120 # Timeout in ms for connecting to zookeeper
121 zookeeper.connection.timeout.ms=6000

 

4.启动ZK
