Flume+Kafka+Strom基于伪分布式环境的结合使用
目录
[toc]
Flume、Kafka、Storm是什么,如何安装?
Flume的介绍，请参考这篇文章《Flume1.5.0的安装、部署、简单应用》
Kafka的介绍，请参考这篇文章《kafka2.9.2的分布式集群安装和demo(java api)测试》
Storm的介绍，请参考这篇文章《ubuntu12.04+storm0.9.2分布式集群的搭建》
在后面的例子中，我们也是使用以上三篇文章中的配置进行测试。
Flume、Kafka、Storm如何结合使用？
0.1 原理是什么？
如何你仔细阅读过关于Flume、Kafka、Storm的介绍，就会知道，在他们各自之间对外交互发送消息的原理。
在后面的例子中，我们主要对Flume的sink进行重构，调用kafka的消费生产者(producer)发送消息;在Sotrm的spout中继承IRichSpout接口，调用kafka的消息消费者(Consumer)来接收消息，然后经过几个自定义的Bolt，将自定义的内容进行输出。
0.2 flume和kafka的整合
复制flume要用到的kafka相关jar到flume目录下的lib里面。
root@m1:/home/hadoop# cp /home/hadoop/kafka_2.9.2-0.8.1.1/libs/kafka_2.9.2-0.8.1.1.jar /home/hadoop/flume-1.5.0-bin/lib
root@m1:/home/hadoop# cp /home/hadoop/kafka_2.9.2-0.8.1.1/libs/scala-library-2.9.2.jar /home/hadoop/flume-1.5.0-bin/lib
root@m1:/home/hadoop# cp /home/hadoop/kafka_2.9.2-0.8.1.1/libs/metrics-core-2.2.0.jar /home/hadoop/flume-1.5.0-bin/lib
编写sink.java文件,然后在eclipse导出jar包，放到flume-1.5.1-bin/lib目录中,项目中要引用flume-ng-configuration-1.5.0.jar,flume-ng-sdk-1.5.0.jar,flume-ng-core-1.5.0.jar,zkclient-0.3.jar,commons-logging-1.1.1.jar,在flume目录中，可以找到这几个jar文件，如果找不到就用find命令搜一下。
package idoall.cloud.flume.sink;
import java.util.Properties;
import kafka.javaapi.producer.Producer;
import kafka.producer.KeyedMessage;
import kafka.producer.ProducerConfig;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.apache.flume.Channel;
import org.apache.flume.Context;
import org.apache.flume.Event;
import org.apache.flume.EventDeliveryException;
import org.apache.flume.Transaction;
import org.apache.flume.conf.Configurable;
import org.apache.flume.sink.AbstractSink;
public class KafkaSink extends AbstractSink implements Configurable {
private static final Log logger = LogFactory.getLog(KafkaSink.class);
private String topic;
private Producer<String, String> producer;
public void configure(Context context) {
topic = "idoall_testTopic";
Properties props = new Properties();
props.setProperty("metadata.broker.list", "m1:9092,m2:9092,s1:9092,s2:9092");
props.setProperty("serializer.class", "kafka.serializer.StringEncoder");
props.put("partitioner.class", "idoall.cloud.kafka.Partitionertest");
props.put("zookeeper.connect", "m1:2181,m2:2181,s1:2181,s2:2181/kafka");
props.setProperty("num.partitions", "4"); //
props.put("request.required.acks", "1");
ProducerConfig config = new ProducerConfig(props);
producer = new Producer<String, String>(config);
logger.info("KafkaSink初始化完成.");
}
public Status process() throws EventDeliveryException {
Channel channel = getChannel();
Transaction tx = channel.getTransaction();
try {
tx.begin();
Event e = channel.take();
if (e == null) {
tx.rollback();
return Status.BACKOFF;
}
KeyedMessage<String, String> data = new KeyedMessage<String, String>(topic, new String(e.getBody()));
producer.send(data);
logger.info("flume向kafka发送消息：" + new String(e.getBody()));
tx.commit();
return Status.READY;
} catch (Exception e) {
logger.error("Flume KafkaSinkException:", e);
tx.rollback();
return Status.BACKOFF;
} finally {
tx.close();
}
}
}
在m1上配置flume和kafka交互的agent
root@m1:/home/hadoop/flume-1.5.0-bin# vi /home/hadoop/flume-1.5.0-bin/conf/kafka.conf
a1.sources = r1
a1.sinks = k1
a1.channels = c1
# Describe/configure the source
a1.sources.r1.type = syslogtcp
a1.sources.r1.port = 5140
a1.sources.r1.host = localhost
a1.sources.r1.channels = c1
# Describe the sink
a1.sinks.k1.type = idoall.cloud.flume.sink.KafkaSink
# Use a channel which buffers events in memory
a1.channels.c1.type = memory
a1.channels.c1.capacity = 1000
a1.channels.c1.transactionCapacity = 100
# Bind the source and sink to the channel
a1.sources.r1.channels = c1
a1.sinks.k1.channel = c1
在m1,m2,s1,s2的机器上,分别启动kafka（如果不会请参考这篇文章介绍了kafka的安装、配置和启动《kafka2.9.2的分布式集群安装和demo(java api)测试》），然后在s1机器上再启动一个消息消费者consumer
t@m1:/home/hadoop# /home/hadoop/kafka_2.9.2-0.8.1.1/bin/kafka-server-start.sh /home/hadoop/kafka_2.9.2-0.8.1.1/config/server.properties &
在m1启动flume
root@m1:/home/hadoop# /home/hadoop/flume-1.5.0-bin/bin/flume-ng agent -c . -f /home/hadoop/flume-1.5.0-bin/conf/kafka.conf -n a1 -Dflume.root.logger=INFO,console

在m1上再打开一个窗口，测试向flume中发送syslog
root@m1:/home/hadoop# echo "hello idoall.org syslog" | nc localhost 5140
m1打开的flume窗口中看最后一行的信息，Flume已经向kafka发送了消息
14/08/19 11:36:34 INFO sink.KafkaSink: KafkaSink初始化完成.

在刚才s1机器上打开的kafka消费端，同样可以看到从Flume中发出的信息，说明flume和kafka已经调试成功了。

测试kafka和storm的结合
打开两个窗口(也可以在两台机器上分别打开，下面的例子中，我会打开m2和s1机器 )，分别m2上运行kafka的producer，在s1上运行kafka的consumer(如果刚才打开了就不用再打开),先测试kafka自运行是否正常。
如下所示，我在m2上运行producer，输入“hello welcome idoall.org”，在s1的机器上consumer同样收到了消息。说明kafka已经运行正常，并且消息通讯也没有问题。
m2机器输出的消息：
root@m2:/home/hadoop# /home/hadoop/kafka_2.9.2-0.8.1.1/bin/kafka-console-producer.sh --broker-st m1:9092 --sync --topic idoall_testTopic
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.
hello welcome idoall.org
s1机器接收的消息：
root@s1:/home/hadoop# /home/hadoop/kafka_2.9.2-0.8.1.1/bin/kafka-console-consumer.sh --zookeeper m1:2181 --topic idoall_testTopic --from-beginning

SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.
hello welcome idoall.org
我们再在Eclipse中运行KafkaTopologytest.java，可以看到在控制台，同样收到了刚才在m2上kafka发送的消息。说明kafka和storm也打通了。
#信息太多，我只截取重要部分：

0.4 flume、kafka、storm的整合
从上面两个例子我们可以看到，flume和kafka之前已经完成了通讯和部署，kafka和storm之间可以正常通讯，只差把storm的相关文件打包成jar部署到storm中即可完成三者的通讯。
Storm的安装、配置、部署，如果不了解，可以参考这篇文章《ubuntu12.04+storm0.9.2分布式集群的搭建》
复制kafka相关的jar包到storm的lib里面。（因为在上面我们已经说过，kafka和storm的整合，主要是重写storm的spout，调用kafka的Consumer来接收消息并打印，所在需要用到这些jar包）
root@m1:/home/hadoop# cp /home/hadoop/kafka_2.9.2-0.8.1.1/libs/kafka_2.9.2-0.8.1.1.jar /home/hadoop/storm-0.9.2-incubating/lib

在s1,s2上启动storm supervisor

在m1上启动storm ui
root@m1:/home/hadoop# /home/hadoop/storm-0.9.2-incubating/bin/storm ui &
将Eclipse中的文件打包成jar复制到做任意目录，然后用storm来运行

在flume中发消息，在storm中看是否有接收到
在flume中发送的消息：
root@m1:/home/hadoop# echo "flume->kafka->storm message" | nc localhost 5140
root@m1:/home/hadoop#
storm中显示的内容：
#内容太多，只截取重要部分

通过以上实例，我们完成了flume、kafka、storm之间的通讯，结合之前介绍的《Flume1.5.0的安装、部署、简单应用(含分布式、与hadoop2.2.0、hbase0.96的案例)》和《[Golang、Php、Python、Java基于Thrift0.9.1实现跨语言调用](/2014/08/golang-php-python-java-thrift/》.如果相互结合，相信在基于大数据实时计算，以及多语言之间的相互调用，能够解决你在项目中的大部分问题。希望最近一系列的文章能够对你有帮助。
