(一) storm的集群安装与配置

机器：

192.168.180.101

192.168.187.16

需要准备的软件有：

zookeeper(zookeeper-3.4.4.tar.gz),storm(storm-0.8.1.zip) ,jdk

1、配置zookeeper

解压zookeeper，将conf目录下的zoo_sample.cfg 重命名为：zoo.cfg

修改后内容为：

# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial 
# synchronization phase can take
initLimit=10
# The number of ticks that can pass between 
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just 
# example sakes.
dataDir=/data/zookeeper/data
dataLogDir=/data/zookeeper/log
# the port at which the clients will connect
clientPort=2181
#
# Be sure to read the maintenance section of the 
# administrator guide before turning on autopurge.
#
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# The number of snapshots to retain in dataDir
#autopurge.snapRetainCount=3
# Purge task interval in hours
# Set to "0" to disable auto purge feature
#autopurge.purgeInterval=1
server.1=192.168.187.16:2888:3888
server.2=192.168.180.101:2888:3888

具体配置可以参看：
 http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_configuration

注意，最后两行的配置：

格式为：server.id=host:port:port

id只能为数字 1-255，同时需要在 dataDir目录下面新建一个文件名为myid的文件，里面的内容只有一行："id"

Every machine that is part of the ZooKeeper ensemble should know about every other machine in the ensemble. You accomplish this with the series of lines of the form server.id=host:port:port. The parameters host and port are straightforward. You attribute the server id to each machine by creating a file named myid, one for each server, which resides in that server's data directory, as specified by the configuration file parameter dataDir.

接着还需要添加环境变量：

export ZOOKEEPER_HOME=/home/zhxia/apps/db/zookeeper

两台机器上环境配置相同，但是myid文件内的id指不一样

 2、配置storm

解压storm

进入conf目录,编辑storm.yaml文件

########## These MUST be filled in for a storm configuration
 storm.zookeeper.servers:
     - "192.168.187.16"
     - "192.168.180.101"

 nimbus.host: "192.168.187.16"

 storm.local.dir: "/data/storm/data"
 ##### 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:
    # - "127.0.0.1"
     #- "server2"
## to nimbus 
#nimbus.childopts: "-Xmx1024m" 
#
## to supervisor 
#supervisor.childopts: "-Xmx1024m" 
#
## to worker 
#worker.childopts: "-Xmx768m" 

配置完成之后，开始启动zookeeper和storm

启动zookeeper

bin/zkServer.sh start

启动storm

bin/storm nimbus

bin/storm supervisor

bin/storm ui
