kafka-1-安装启动测试

1、安装工具brew install kafka 会自动安装依赖zookeeper

2、安装配置文件位置 /usr/local/etc/kafka|zookeeper

修改/usr/local/Cellar/kafka/2.2.0/libexec/config
server.conf

############################# Server Basics #############################
 
# The id of the broker. This must be set to a unique integer for each broker.
broker.id=0
 
# Switch to enable topic deletion or not, default value is false
#delete.topic.enable=true
 
############################# 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 = listener_name://host_name:port
#   EXAMPLE:
#     listeners = PLAINTEXT://your.host.name:9092
listeners=PLAINTEXT://192.168.1.104:9092
 
# Hostname and port the broker will advertise to producers and consumers. If not set, 
# it uses the value for "listeners" if configured.  Otherwise, it will use the value
# returned from java.net.InetAddress.getCanonicalHostName().
 
advertised.listeners=PLAINTEXT://192.168.1.104:9092
hostname=192.168.1.104
 
 
# Maps listener names to security protocols, the default is for them to be the same. See the config documentation for more details
#listener.security.protocol.map=PLAINTEXT:PLAINTEXT,SSL:SSL,SASL_PLAINTEXT:SASL_PLAINTEXT,SASL_SSL:SASL_SSL
 
# 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
 
 
############################# Log Basics #############################
 
# 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
 
############################# Log Flush Policy #############################
 
# Messages are immediately written to the filesystem but by default we only fsync() to sync
# the OS cache lazily. The following configurations control the flush of data to disk.
# There are a few important trade-offs here:
#    1. Durability: Unflushed data may be lost if you are not using replication.
#    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.
#    3. Throughput: The flush is generally the most expensive operation, and a small flush interval may lead to exceessive seeks.
# The settings below allow one to configure the flush policy to flush data after a period of time or
# every N messages (or both). This can be done globally and overridden on a per-topic basis.
# The number of messages to accept before forcing a flush of data to disk
#log.flush.interval.messages=10000
 
# The maximum amount of time a message can sit in a log before we force a flush
#log.flush.interval.ms=1000
 
############################# Log Retention Policy #############################
 
# The following configurations control the disposal of log segments. The policy can
# be set to delete segments after a period of time, or after a given size has accumulated.
# A segment will be deleted whenever *either* of these criteria are met. Deletion always happens
# from the end of the log.
 
# The minimum age of a log file to be eligible for deletion due to age
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. Functions independently of log.retention.hours.
#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
############################# Zookeeper #############################
# Zookeeper connection string (see zookeeper docs for details).
# This is a comma separated host:port pairs, each corresponding to a zk
# server. e.g. "127.0.0.1:3000,127.0.0.1:3001,127.0.0.1:3002".
# You can also append an optional chroot string to the urls to specify the
# root directory for all kafka znodes.
zookeeper.connect=192.168.1.104:2181
# Timeout in ms for connecting to zookeeper
zookeeper.connection.timeout.ms=6000

3、启动 zookeeper

cd /usr/local/Cellar/kafka/2.2.0

./bin/zookeeper-server-start /usr/local/etc/kafka/zookeeper.properties

4、启动kafka服务

./bin/kafka-server-start /usr/local/etc/kafka/server.properties

5、创建topic

./bin/kafka-topics --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic test1

6、查看创建的topic

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

7、生产数据

./bin/kafka-console-producer --broker-list localhost:9092 --topic test1

8、消费数据

新版启动

消费

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