storm启动过程

zookeeper启动并测试
1、在所有服务器中执行：zookeeper-3.4.3/bin/zkServer.sh start
2、输入jps命令查看进程：
3、查看状态：zookeeper-3.4.3/bin/zkServer.sh status
4、启动客户端脚本：zookeeper-3.4.3/bin/zkCli.sh -server zookeeper:2181

5、停止zookeeper进程：zookeeper-3.4.3/bin/zkServer.sh stop

start kafka:

Step 1: Download the code


Download the 0.8 release.
> tar xzf kafka-<VERSION>.tgz
> cd kafka-<VERSION>
> ./sbt update
> ./sbt package
> ./sbt assembly-package-dependency
This tutorial assumes you are starting on a fresh zookeeper instance with no pre-existing data. If you want to migrate from an existing 0.7 installation you will need to follow the migration instructions.
Step 2: Start the server


Kafka uses zookeeper so you need to first start a zookeeper server if you don't already have one. You can use the convenience script packaged with kafka to get a quick-and-dirty single-node zookeeper instance.


> bin/zookeeper-server-start.sh config/zookeeper.properties
[2013-04-22 15:01:37,495] INFO Reading configuration from: config/zookeeper.properties (org.apache.zookeeper.server.quorum.QuorumPeerConfig)
...
Now start the Kafka server:
> bin/kafka-server-start.sh config/server.properties
[2013-04-22 15:01:47,028] INFO Verifying properties (kafka.utils.VerifiableProperties)
[2013-04-22 15:01:47,051] INFO Property socket.send.buffer.bytes is overridden to 1048576 (kafka.utils.VerifiableProperties)
...
Step 3: Create a topic


Let's create a topic named "test" with a single partition and only one replica:
> bin/kafka-create-topic.sh --zookeeper localhost:2181 --replica 1 --partition 1 --topic test
We can now see that topic if we run the list topic command:
> bin/kafka-list-topic.sh --zookeeper localhost:2181
Alternatively, you can also configure your brokers to auto-create topics when a non-existent topic is published to.
Step 4: Send some messages


Kafka comes with a command line client that will take input from a file or standard in and send it out as messages to the Kafka cluster. By default each line will be sent as a separate message.
Run the producer and then type a few messages to send to the server.


> bin/kafka-console-producer.sh --broker-list localhost:9092 --topic test 
This is a message
This is another message
Step 5: Start a consumer


Kafka also has a command line consumer that will dump out messages to standard out.
> bin/kafka-console-consumer.sh --zookeeper localhost:2181 --topic test --from-beginning
This is a message
This is another message
If you have each of the above commands running in a different terminal then you should now be able to type messages into the producer terminal and see them appear in the consumer terminal.


All the command line tools have additional options; running the command with no arguments will display usage information documenting them in more detail.

storm执行：
# bin/storm nimbus（启动主节点）最好后台执行 + &
# bin/storm supervisor（启动从节点） 最好后台执行 + &
执行命令：# storm jar StormStarter.jar storm.starter.WordCountTopology test
此命令的作用就是用storm将jar发送给storm去执行，后面的test是定义的toplogy名称。
搞定，任务就发送到storm上运行起来了，还可以通过命令：
# bin/storm ui 最好后台执行 + &
然后执行 jps 会看到 3 个进程：zookeeper 、nimbus、 supervisor
启动ui，可以通过浏览器， ip:8080/ 查看运行i情况。端口号是由storm/conf/storm.yaml中ui.port 指定
