########### These MUST be filled in for a storm configuration
storm.zookeeper.servers:
- "192.168.1.10"
- "192.168.1.11"
nimbus.host : "192.168.1.10"
storm.local.dir : "/opt/stormtmp/data"
ui.port : 8080
supervisor.slots.ports :
-6700
-6701
-6702
-6703
#
#
# ##### 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:
# - "server1"
# - "server2"
## Metrics Consumers
# topology.metrics.consumer.register:
# - class: "backtype.storm.metric.LoggingMetricsConsumer"
# parallelism.hint: 1
# - class: "org.mycompany.MyMetricsConsumer"
# parallelism.hint: 1
# argument:
# - endpoint: "metrics-collector.mycompany.org"
配置详解：
storm.zookeeper.servers: ZooKeeper服务器列表
supervisor.slots.ports :且每个端口只运行一个worker.通过这项配置可以调整每台机器上运行的worker数.(调整slot数/每机)
Storm.local.dir：storm使用的本地文件系统目录(必须存在并且storm进程可读写)
Nimbus.host：nimbus服务器地址
Ui.port:Storm UI的服务端口
nimbus.host :nimbus服务器地址
2、启动storm。先启动10的storm。
./storm nimbus &
./storm supervisor &
./storm ui &
IP为11结尾的机器运行
./storm supervisor &
3、查看运行状态，访问localhost:8080,进入storm ui界面，查看集群成功。
