简介
最近开发的项目中，kafka用的比较多，为了方便梳理，从今天起准备记录一些关于kafka的文章，首先，当然是如何安装kafka了。
Apache Kafka是分布式发布-订阅消息系统。
Apache Kafka与传统消息系统相比，有以下不同：
- 它被设计为一个分布式系统，易于向外扩展；
- 它同时为发布和订阅提供高吞吐量；
- 它支持多订阅者，当失败时能自动平衡消费者；
- 它将消息持久化到磁盘，因此可用于批量消费，例如ETL，以及实时应用程序。
安装 kafka
下载地址：http://mirrors.tuna.tsinghua.edu.cn/apache/kafka/2.3.0/kafka_2.11-2.3.0.tgz
wget http://mirrors.tuna.tsinghua.edu.cn/apache/kafka/2.3.0/kafka_2.11-2.3.0.tgz
解压
tar -zxvf kafka_2.-2.3..tgz
cd /usr/local/kafka_2.-2.3./
修改 kafka-server 的配置文件
vi /usr/local/kafkaa_2.11-2.3.0/config/server.properties
修改如下
broker.id=
log.dir=/data/kafka/logs-
当然，也可以不修改，只是demo测试，默认配置即可。
常用功能简介
1、启动 zookeeper
使用安装包中的脚本启动单节点 Zookeeper 实例：
sh bin/zookeeper-server-start.sh -daemon config/zookeeper.properties
2、启动Kafka 服务
使用 kafka-server-start.sh 启动 kafka 服务：
sh bin/kafka-server-start.sh config/server.properties

3、创建 topic
使用 kafka-topics.sh 创建单分区单副本的 topic test：
sh bin/kafka-topics.sh --create --zookeeper localhost: --replication-factor --partitions --topic test
结果
Created topic test.
查看 topic 列表：
bin/kafka-topics.sh --list --zookeeper localhost:
结果
test
4、产生消息
使用 kafka-console-producer.sh 发送消息：
sh bin/kafka-console-producer.sh --broker-list localhost: --topic test
5、消费消息
使用 kafka-console-consumer.sh 接收消息并在终端打印：
sh bin/kafka-console-consumer.sh --zookeeper localhost: --topic test --from-beginning
打开个新的命令窗口执行上面命令即可查看信息：
出错
zookeeper is not a recognized option
原因：我们使用的是高版本的kafka,换成以下命令
sh bin/kafka-console-consumer.sh --bootstrap-server localhost: --topic test --from-beginning
可以看到这回发布的消息都可以订阅到了。
6、查看描述 topics 信息
sh bin/kafka-topics.sh --describe --zookeeper localhost: --topic test
结果：
解释
第一行给出了所有分区的摘要，每个附加行给出了关于一个分区的信息。 由于我们只有一个分区，所以只有一行。
“Leader”: 是负责给定分区的所有读取和写入的节点。 每个节点将成为分区随机选择部分的领导者。
“Replicas”: 是复制此分区日志的节点列表，无论它们是否是领导者，或者即使他们当前处于活动状态。
“Isr”: 是一组“同步”副本。这是复制品列表的子集，当前活着并被引导到领导者。
集群配置
Kafka 支持两种模式的集群搭建：一种是在单机上运行多个 broker 实例来实现集群，一种是在多台机器上搭建集群。
下面介绍下如何实现单机多 broker 实例集群，其实很简单，只需要如下配置即可。
单机多broker 集群配置
利用单节点部署多个 broker。 不同的 broker 设置不同的 id，监听端口及日志目录。 例如：
cp config/server.properties config/server-.properties
cp config/server.properties config/server-.properties
vim config/server-.properties
vim config/server-.properties
修改 ：
broker.id=
listeners = PLAINTEXT://your.host.name:9093
log.dir=/data/kafka/logs-
和
broker.id=
listeners = PLAINTEXT://your.host.name:9094
log.dir=/data/kafka/logs-
启动Kafka服务：
bin/kafka-server-start.sh config/server-.properties &
bin/kafka-server-start.sh config/server-.properties &
至此，单机多broker实例的集群配置完毕。
多机多 broker 集群配置
分别在多个节点按上述方式安装 Kafka，配置启动多个 Zookeeper 实例。
假设三台机器 IP 地址是 ： 192.168.153.135， 192.168.153.136， 192.168.153.137
分别配置多个机器上的 Kafka 服务，设置不同的 broker id，zookeeper.connect 设置如下:
vim config/server.properties
里面的 zookeeper.connect
修改为：
zookeeper.connect=192.168.153.135:,192.168.153.136:,192.168.153.137:
