【预研】Ubuntu 12.04 64 bit Storm的单机版本的安装和运行

基础知识思考整理
http://www.jb51.cc/article/p-cudsbmht-bep.html

主要是Storm流计算的简单的环境的搭建和简单的demo的运行。
当前系统和系统中已经预装的软件：
其中软件包括jdk1.7.0_79、python2.7.6、zookeeper3.3.5

如果没装的话，可以大致按照[1]这个安装这些软件。

安装ZeroMQ和jzmq

Storm底层是基于ZeroMQ消息队列的，所以还需要安装ZeroMQ和其java版本，但是在编译的过程中可能会遇到一些问题，主要是配置和编译的问题，可以通过[2]中的方式解决，同时按照[3]来进行相关配置。

安装Storm

参照[1][3]可以完成安装，主要是下载和相应的文件的配置。

测试安装

以上完成整个单机版本Storm的环境的配置，下面是Storm自带的examples中的storm-starter例子（也就是WordCountTopology）的运行。
启动Storm
cd /path/to/zookeeper/bin/
./zkServer.sh start #启动zookeeper
cd /path/to/storm/bin
./storm nimbus &
./storm supervisor &
./storm ui &
启动完成后利用jps查看后台进程：

运行demo

确保可以成功启动后来进入storm-starter进行WordCountTopology例子的运行：
实际下面的过程就是strom-starter中README.markdown中的说明和步骤：
前面熟悉平台和相应例子代码的过程先略过，来看利用Maven运行storm-starter：
安装Maven3.x
对Storm首先进行一个本地构建

# Must be run from the top-level directory of the Storm code repository
$ mvn clean install -DskipTests=true

上面的命令在本地构建Storm并将jar包安装到$HOME/.m2/repository中，后面运行maven命令的时候，Maven能够找到相应的Storm版本等信息。
将storm-starter打包，便于提交和运行

$ mvn package

生成的包存于storm-starter的target目录下，命名为storm-starter-版本.jar
后面进行提交的时候可以使用这个包进行提交。

# Example 1: Run the ExclamationTopology in local mode (LocalCluster)
$ storm jar target/storm-starter-*.jar org.apache.storm.starter.ExclamationTopology

# Example 2: Run the RollingTopWords in remote/cluster mode,
# under the name "production-topology"
$ storm jar storm-starter-*.jar org.apache.storm.starter.RollingTopWords production-topology remote

运行wordCountTopology例子：

cd /path/to/storm/bin
./storm jar path/to/generated.jar org.apache.storm.starter.WordCountTopology

运行结果，输出比较多，整理其中一个例子查看：

可以看到这是“I am at two with nature”的一个统计词频的结果。
