Kafka安装部署
1下载并安装JDK参考jdk的安装，需要jdk1.6+。
2 Kafka的安装
2.1 下载kafka
下载地址：http://mirrors.hust.edu.cn/apache/kafka/0.10.0.1/kafka_2.11-0.10.0.1.tgz
2.2 解压安装包
$ tar zvxf kafka_2.11-0.10.0.1.tgz
2.3 复制解压后的文件夹到安装目录
$ cp -r kafka_2.11-0.10.0.1 /software/
2.4 创建kafka安装目录的软链接
$ ln -s /software/kafka_2.11-0.10.0.1/software/kafka
2.5 配置环节变量
修改/etc/profile文件内容：
export KAFKA_HOME=/software/kafka
export PATH=$KAFKA_HOME/bin:$FLUME_HOME/bin:$ZOOKEEPER_HOME/bin:$HBASE_HOME/bin:
$HIVE_HOME/bin:$JAVA_HOME/bin:$HADOOP_HOME/bin:$HADOOP_HOME/sbin:$PATH
export CLASSPATH=.:$KAFKA_HOME/libs/*:$FLUME_HOME/lib/*:$HBASE_HOME/lib/*:$JAVA_
HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
2.6 启动kafka
1）、启动kafka前要先启动zookeeper
$ zookeeper-server-start.sh/software/kafka/config/zookeeper.properties &
2）、启动kafka
$ kafka-server-start.sh/software/kafka/config/server.properties &
3 体验单节点Kafka
3.1 创建topic
$ kafka-topics.sh --create --zookeeperlocalhost:2181 --replication-factor 1 --partitions 1 --topic test
查询创建的topic
$ kafka-topics.sh --list --zookeeperlocalhost:2181
3.2 发送消息
$ kafka-console-producer.sh --broker-listlocalhost:9092 --topic test
This is a message
This is another message
3.3 消费消息
$ kafka-console-consumer.sh --bootstrap-serverlocalhost:9092 --zookeeper localhost:2181 --topic test --from-beginning
This is a message
This is another message
4 搭建多broker的Kafka集群
4.1 复制配置文件
$ cd /software/kafka/config/
$ cp server.properties s1.properties
$ cp server.properties s2.properties
$ cp server.properties s3.properties
4.2 修改配置文件
config/s1.properties:
broker.id=1
listeners=PLAINTEXT://:9093
log.dir=/tmp/kafka-logs-1
config/s2.properties:
broker.id=2
listeners=PLAINTEXT://:9094
log.dir=/tmp/kafka-logs-2
config/s3.properties:
broker.id=3
listeners=PLAINTEXT://:9095
log.dir=/tmp/kafka-logs-3
4.3 启动kafka
$ kafka-server-start.sh/software/kafka/config/s1.properties &
$ kafka-server-start.sh/software/kafka/config/s2.properties &
$ kafka-server-start.sh /software/kafka/config/s3.properties&
4.4 创建topic
$ kafka-topics.sh --create--zookeeper localhost:2181 --replication-factor 3 --partitions 1 --topicmy-replicated-topic
查看topic描述
$ kafka-topics.sh --describe --zookeeper localhost:2181 --topicmy-replicated-topic
4.5 发送消息
$ kafka-console-producer.sh --broker-listlocalhost:9093 --topic my-replicated-topic
my test msg 1
my test msg 2
my test msg 3
4.6 消费消息
$ kafka-console-consumer.sh--zookeeper localhost:2181 --from-beginning --topic my-replicated-topic
5 容错测试
5.1 找到s1进程
$ ps -ef| grep s1.properties
5.2 杀死进程s1
kill pid
5.3 查看主题描述
$>kafka-topics.sh --describe --zookeeperlocalhost:2181 --topic my-replicated-topic
Topic:my-replicated-topic PartitionCount:1 ReplicationFactor:3 Configs:
Topic: my-replicated-topic Partition: 0 Leader: 2 Replicas:1,2,0 Isr: 2,0
5.4 启动消费者消费主题消息
$>kafka-console-consumer.sh--zookeeper localhost:2181 --from-beginning --topic my-replicated-topic
my test message 1 my test message 26 完全分布式搭建
6.1 将kafka安装文件夹分发到其余集群服务器
$ xsync kafka_2.11-0.10.0.1/
$ xsync kafka
6.2 分发环境变量
#xsync /etc/profile
6.3 修改server.properties属性文件并分发
broker.id=203 #修改broker的id
log.dirs=/home/hadoop/kafka/logs #修改日志的存放路径
zookeeper.connect=s201:2181,s202:2181,s203:2181 #修改zookeeper的连接路径
6.4 启动Kafka集群
到部署kafka每台服务器上面启动kafka集群
$ kafka-server-start.sh/software/kafka/config/server.properties &
$ kafka-server-start.sh/software/kafka/config/server.properties &
$ kafka-server-start.sh/software/kafka/config/server.properties &
