03.Kafka Windows初体验

Step1：下载kafka组件

访问http://kafka.apache.org/官网，下载相应的版本

我的文件目录如下，下面的文件路径也是基于此，按照自己的实际文件路径自行更改

 

        

 

Step2：启动ZooKeeper实例，启动Broker

zookeeper-server-start.bat ..\..\config\zookeeper.properties

kafka-server-start.bat ..\..\config\server.properties

 

部分配置文件

zookeeper.properties

# the directory where the snapshot is stored.
dataDir=/tmp/zookeeper
# the port at which the clients will connect
clientPort=2181
# disable the per-ip limit on the number of connections since this is a non-production config
maxClientCnxns=0

 

server.properties

# The id of the broker. This must be set to a unique integer for each broker.
broker.id=0

# The number of threads handling network requests
num.network.threads=3

# The number of threads doing disk I/O
num.io.threads=8

# 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.bytes=102400

# The maximum size of a request that the socket server will accept (protection against OOM)
socket.request.max.bytes=104857600

# A comma seperated list of directories under which to store log files
log.dirs=/tmp/kafka-logs

# 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=1

# The minimum age of a log file to be eligible for deletion
log.retention.hours=168

# A size-based retention policy for logs. Segments are pruned from the log as long as the remaining
# segments don't drop below log.retention.bytes.
#log.retention.bytes=1073741824

# The maximum size of a log segment file. When this size is reached a new log segment will be created.
log.segment.bytes=1073741824

# The interval at which log segments are checked to see if they can be deleted according
# to the retention policies
log.retention.check.interval.ms=300000

# server. e.g. "127.0.0.1:3000,127.0.0.1:3001,127.0.0.1:3002".
zookeeper.connect=localhost:2181

# Timeout in ms for connecting to zookeeper
zookeeper.connection.timeout.ms=6000

Step3：创建Topic

kafka-topics.bat --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic test

 

 Step4：启动producer发送消息

kafka-console-producer.bat --broker-list localhost:9092 --topic test

 

Step5：启动Consumer接收消息

kafka-console-consumer.bat --bootstrap-server localhost:9092 --topic test --from-beginning

 

------------------------------------------华丽丽的分割线----------------------------------------------------

以上是单个的broker，下面我们进行创建多broker的集群

Step6：创建两个broker

复制两份server.properties分别为server-1.properties和server-2.properties

两个配配置文件其他位置与server.properties相同，不同之处如下

#config/server-1.properties:
broker.id=1
listeners=PLAINTEXT://:9093
log.dirs=/tmp/kafka-logs-1

#config/server-2.properties:
broker.id=2
listeners=PLAINTEXT://:9094
log.dirs=/tmp/kafka-logs-2

启动zookeeper启动两个broker

zookeeper-server-start.bat ..\..\config\zookeeper.properties

kafka-server-start.bat ..\..\config\server-1.properties

kafka-server-start.bat ..\..\config\server-2.properties

 Step7：创建新的topic

kafka-topics.bat --create --zookeeper localhost:2181 --replication-factor 2 --partitions 1 --topic my-replicated-topic

 Step8：启动producer发送消息

kafka-console-producer.bat --broker-list localhost:9093,localhost:9094 --topic my-replicated-topic

 

Step9：启动Consumer接收消息

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

 

Step10：我们关掉server-1或者server-2中的其中一个仍然可以收发消息
