storm 集群配置

配置storm集群的过程中出现写问题，记录下来

1.storm是通过zookeeper管理的，先要安装zookeeper，从zk官网上下来，我这里下下来的的3.4.9,下载后移动到/usr/local,并解压。

tar -zxvf zookeeper-3.4.9.tar.gz

2.进入conf目录，复制zoo_sample.cfg且改名未zoo.cfg,修改zoo.cfg配置文件

cp zoo_sample.cfg /usr/local/zookeeper-3.4.9/conf/zoo.cfg

打开gedit zoo.cfg，配置：

# 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=/tmp/zookeeper
dataLogDir=/tmp/zookeeperlogs
# the port at which the clients will connect
clientPort=2181
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60
#
# 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=192.168.154.129:2888:3888
server.2=192.168.154.133:2888:3888
server.3=192.168.154.132:2888:3888

注意红色部分，这个dataDir 下需要建立 myid，每个myid 的目录要和 dataDir 指定的目录相同，且每个机器的myid 不同，myid的值范围是1-255.

vi myid

3. server.myid=ip:port1:port2,ip 可以是本地的ip，如果在/etc/hosts 配置，也可以用该hosts的配置来制定，port1是默认指定端口，port2备用端口。

之后配置环境变量，vim /etc/profile,将其添加到环境变量中

export ZOOKEEPER_HOME=/usr/local/zookeeper-3.4.9

配置后发送到 另外的两台机器，

scp -r /usr/local/zookeeper-3.4.9 root@192.168.154.133:/usr/local  (注意文件要加-r)

输入密码后即可，和上面类似配置zoo.cfg, vi myid ，修改环境变量，创建zookeeper的日志目录。

4.启动 zk

bin/zkServer.sh start ,用jps查看 是否成功，看到有quorumPeerMain显示成功

用bin/zkCli.sh -server 192.168.154.132:2181 测试是否可以链接到另外两台。

5.安装storm

从官网下载storm,我下载的0.9.6，非最新版本，下载后解压到 /usr/local/storm目录下

tar -zxvf apache-storm-0.9.6.tar.gz

6.进入conf目录下，修改storm.yaml

########### These MUST be filled in for a storm configuration
  storm.zookeeper.servers:
      - "192.168.154.129"
      - "192.168.154.132" 
      - "192.168.154.133"
  storm.zookeeper.port: 2181
#     - "server1"
#     - "server2"
#
  nimbus.host: "192.168.154.129"
#
#
# ##### 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"
  storm.local.dir: "/tmp/storm"
  supervisor.slots.ports:
      -6700 
      -6701 
      -6702 
      -6703 
## 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"

注意 上面的红色部分，前面要加上空格，要不会报expected '<document start>', but found BlockMappingStart
 in 'reader', line 46, column 1:
    supervisor.slots.ports:

我就是这个问题折腾了好久，，经试验原来是这几个配置名称前需要加空格。即：

空格nimbus.host: "192.168.1.101"

空格storm.zookeeper.port: 2181

空格storm.local.dir: "home/hadoop/storm-0.9.1/data"

空格supervisor.slots.ports:

 

大家配置storm.yaml时一定要注意了。少一个空格竟然就启动不了，真是不可思议。

7.配置完后把该配置文件scp到另外另个机器上

scp -r /usr/local/storm/apache-storm-0.9.6 root@192.168.154.132:/usr/local/storm（注意创建storm目录或者直接传输storm文件夹）

输入密码后即可。

8.启动

在主机上面启动 bin/storm nimbus & ,在另外两台机器上面启动bin/storm supervisor &

通过ui 界面查看是否成功，在随意机器上 bin/storm ui ，启动后在浏览器输入 ip：8080 启动成功界面：
