由于CDH5.12本身不集成Strom，所以需要单独使用Strom + Zookeeper 进行集群安装和搭建。
5个节点，1主4从，分别是node[5,7,8,10,11],zookeeper是node2,node8,node11。
可以从Storm 官网下载对应组件，也可以在本书提供的套件里面下载使用。
将Storm解压到/opt/目录下：
输入命令：tar apache-storm-1.1.1.tar.gz -C /opt/
每个节点修改Storm 配置文件：
输入命令：vi /opt/apache-storm-1.1.1/conf/storm.yaml
会显示如下结果：

########### These MUST be filled in for a storm configuration
storm.zookeeper.servers:
- "node2"
- "node8"
- "node11"
#
nimbus.seeds: ["node8"]
#
#
# ##### These may optionally be filled in:
#
## List of custom serializations
# topology.kryo.register:
# - org.mycompany.MyType
# - org.mycompany.MyType2: org.mycompany.MyType2Serializer
#
## List of custom kryo decorators
# topology.kryo.decorators:
# - org.mycompany.MyDecorator
#
## Locations of the drpc servers
drpc.servers:
- "node8"
# - "server2"
## Metrics Consumers
## max.retain.metric.tuples
## - task queue will be unbounded when max.retain.metric.tuples is equal or less than 0.
## whitelist / blacklist
## - when none of configuration for metric filter are specified, it'll be treated as 'pass all'.
## - you need to specify either whitelist or blacklist, or none of them. You can't specify both of them.
## - you can specify multiple whitelist / blacklist with regular expression
## expandMapType: expand metric with map type as value to multiple metrics
## - set to true when you would like to apply filter to expanded metrics
## - default value is false which is backward compatible value
## metricNameSeparator: separator between origin metric name and key of entry from map
## - only effective when expandMapType is set to true
# topology.metrics.consumer.register:
# - class: "org.apache.storm.metric.LoggingMetricsConsumer"
# max.retain.metric.tuples: 100
# parallelism.hint: 1
# - class: "org.mycompany.MyMetricsConsumer"
# max.retain.metric.tuples: 100
# whitelist:
# - "execute.*"
# - "^__complete-latency$"
# parallelism.hint: 1
# argument:
# - endpoint: "metrics-collector.mycompany.org"
# expandMapType: true
# metricNameSeparator: "."
## Cluster Metrics Consumers
# storm.cluster.metrics.consumer.register:
# - class: "org.apache.storm.metric.LoggingClusterMetricsConsumer"
# - class: "org.mycompany.MyMetricsConsumer"
# argument:
# - endpoint: "metrics-collector.mycompany.org"
#
# storm.cluster.metrics.consumer.publish.interval.secs: 60
每个节点修改软连接：
输入命令：ln -s /opt/apache-storm-1.1.1/bin/storm /usr/bin/storm
node8:节点启动：
storm nimbus & ;
storm ui &;
storm supervisor &
其余节点启动：
storm supervisor &
会显示如下图示：
此时，storm环境搭建完毕。
