kafka安装应用，zookeeper集群集成测试应用

github:客户端测试项目例子：https://github.com/liangrui1988/kafka-client
官方文档：http://kafka.apache.org/quickstart
kafka自身带有zookeeper,但如果集群的话，还是分开部署好点。
窗口会开很多，上个图先看下：

在每一个数据文件目录中，新建一个myid文件，文件必须是唯一的服务标识，在后面的配置中会用到  

在指定data/server*下面新建文件

echo '1'>path/data/server1/myid
echo '2'>path/data/server2/myid
echo '3'>path/data/server3/myid

#     listeners = listener_name://host_name:port
#   EXAMPLE:

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

# A comma seperated list of directories under which to store log files
log.dirs=/home/web_admin/temp/s1-kafka/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

############################# Internal Topic Settings  #############################

# For anything other than development testing, a value greater than 1 is recommended for to ensure availability such as 3.
offsets.topic.replication.factor=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=192.168.20.243:2181,192.168.20.243:22181,192.168.20.243:32181

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

############################# Group Coordinator Settings #############################

# The following configuration specifies the time, in milliseconds, that the GroupCoordinator will delay the initial consumer rebalance.
# The rebalance will be further delayed by the value of group.initial.rebalance.delay.ms as new members join the group, up to a maximum of max.poll.interval.ms.
# The default value for this is 3 seconds.
# We override this to 0 here as it makes for a better out-of-the-box experience for development and testing.
# However, in production environments the default value of 3 seconds is more suitable as this will help to avoid unnecessary, and potentially expensive, rebalances during application startup.
group.initial.rebalance.delay.ms=0

启动:
bin/kafka

bin/kafka-server-start.sh config/server-2.properties
bin/kafka-server-start.sh config/server.properties

测试：
打开三个消费终端
bin/kafka-console-consumer.sh --zookeeper 192.168.20.243:2181 --topic test3 --from-beginning
bin/kafka-console-consumer.sh --zookeeper 192.168.20.243:22181 --topic test3 --from-beginning
bin/kafka-console-consumer.sh --zookeeper 192.168.20.243:32181 --topic test3 --from-beginning
打开-个生产终端
bin/kafka-console-producer.sh --broker-list 192.168.20.243:9092 --topic test3

输入消息，三个终端会同时接收到消息。
当kill掉主zookeeper时，其它服务还是一样可以接收，

附加：

创建topic 分配两个副本在不同服务上（备用，如果节点挂了就切换），一个分区（可以多个）
bin/kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 2 --partitions 1 --topic test2

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

查看topic属性
bin/kafka-topics.sh --describe --zookeeper localhost:2181 --topic test

配置Log Cleaner 日志压缩
log.cleaner.enable=true

启动cleaner线程池，要启动一个特定的topic，你可以添加特定的日志属性：
log.cleanup.policy=compact

查看偏移位置
bin/kafka-consumer-groups.sh --bootstrap-server broker1:9092 --describe --group test-consumer-group

查看zk状态
bin/zkServer.sh status
