0.有的地方我已经整理成脚本了,有的命令是脚本里面截取的

1.启动hadoop和yarn

$HADOOP_HOME/sbin/start-dfs.sh;$HADOOP_HOME/sbin/start-yarn.sh

2.启动zk

#主机名是mini-mini3所以这里可以遍历

echo "start zkserver "

for i in 1 2 3

do

ssh mini$i "source /etc/profile;$ZK_HOME/bin/zkServer.sh start"

done

3.启动mysqld

service mysqld start

4.启动kafka,集群都要启动

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

5.启动storm

在nimbus.host所属的机器上启动nimbus服务

nohup ./storm nimbus &

在nimbus.host所属的机器上启动ui服务

nohup ./storm ui &

在其它机器上启动supervisor服务

nohup ./storm supervisor &

6.启动flume

#exec.conf

a1.channels=r1

a1.sources=c1

a1.sinks=k1

#a1.sources.c1.type=spooldir #实时性要求不高的话，可以用这种方式，ta

#a1.sources.c1.channels=r1

#a1.sources.c1.spoolDir= /opt/flumeSpool/#a1.sources.c1.fileHeader= falsea1.sources.c1.type=exec

a1.sources.c1.command= tail -F /home/hadoop/kafkastudy/data/flume_sour

a1.sources.c1.channels=r1

a1.sinks.k1.type=org.apache.flume.sink.kafka.KafkaSink

a1.sinks.k1.topic=orderMq

a1.sinks.k1.brokerList= mini1:9092,mini2:9092,mini3:9092a1.sinks.k1.requiredAcks= 1a1.sinks.k1.batchSize= 20a1.sinks.k1.channel=r1

a1.channels.r1.type=memory

a1.channels.r1.capacity= 10000a1.channels.r1.transactionCapacity= 1000

bin/flume-ng agent --conf conf --conf-file conf/myconf/exec.conf --name a1 -Dflume.root.logger=INFO,console

7.启动造数据的程序

#!/bin/bashfor((i=0;i<50000;i++))doecho"msg-"+$i >> /home/hadoop/kafkastudy/data/flume_sources/click_log/1.log

done

8在mini1:8080上观察

总结

a.造数据和flume之间的链接是在exec.conf文件中配置了flume监听了文件,这个文件是造数据成员生成的,这里相当于数据源

b.flume和kafka之间的链接1在exec.conf中配置了.使用kafka的shell消费消息命令可以查看到

bin/kafka-console-consumer.sh --zookeeper mini1:2181  --topic test1

c.kafka和storm之间的链接,是由于我们在storm上运行了自己定义的一个程序,这个程序就是kafka2tostorm,在程序中指定了KafaSpout.同时还包含了自己的业务

d.

StormSubmitter.submitTopology(args[0], conf, topologyBuilder.createTopology());

}else{

localCluster.submitTopology("storm2kafka", conf, topologyBuilder.createTopology());

}

}
