(一) storm的集群安裝與配置

機器：

192.168.180.101

192.168.187.16

需要准備的軟件有：

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

1、配置zookeeper

解壓zookeeper，將conf目錄下的zoo_sample.cfg 重命名為：zoo.cfg

修改后內容為：

# 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

具體配置可以參看：
 http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_configuration

注意，最后兩行的配置：

格式為：server.id=host:port:port

id只能為數字 1-255，同時需要在 dataDir目錄下面新建一個文件名為myid的文件，里面的內容只有一行："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.

接着還需要添加環境變量：

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

兩台機器上環境配置相同，但是myid文件內的id指不一樣

 2、配置storm

解壓storm

進入conf目錄,編輯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，開始啟動zookeeper和storm

啟動zookeeper

bin/zkServer.sh start

啟動storm

bin/storm nimbus

bin/storm supervisor

bin/storm ui
