如何配置多节点Apache Storm群集

Question

我在跟踪http://jayatiatblogs.blogspot.com/2011/11/storm-installation.html

我的主节点10.0.0.185。我的从节点10.0.0.79，10.0.0.124

下面是我的动物园。我的从属节点的cfg：

tickTime=2000
initLimit=10
syncLimit=5

dataDir=/home/ubuntu/zookeeper-data
clientPort=2181

server.1=10.0.0.79:2888:3888
server.2=10.0.0.124:2888:3888
server.3=10.0.0.84:2888:3888

autopurge.snapRetainCount=3
autopurge.purgeInterval=1

下面是我的Storm。我的从属节点的yaml：

########### These MUST be filled in for a storm configuration
 storm.zookeeper.server:
     - "10.0.0.79"

我在所有从属节点中启动zookeeper，然后在主节点中启动storm nimbus，然后在所有从属节点中启动storm supervisor。然而，当我在Storm UI中查看时，集群摘要中只有一个主管，总共有5个插槽

在这种情况下，如果我提交拓扑，实际上有多少从节点在工作？

为什么不是3个主管总共有15个职位？

我应该怎么做才能有3个主管？

当我向主管报到时。登录从节点，原因如下：

2015-05-29T09:21:24.185+0000 b.s.d.supervisor [INFO] 5019754f-cae1-4000-beb4-fa0
16bd1a43d still hasn't started

Answer 1

你是说Nimbus是主节点吗？

一般来说，应该先启动Zookeeper集群，然后启动nimbus，然后启动管理员。Zookeeper和Nimbus应始终可用，以便Storm群正常运行。

您应该检查主管日志以检查故障。Nimbus主机和Zookeeper机器应该可以从监控机器访问。

Answer 2

你所做的一切都很完美，而且效果也很好。

你唯一应该改变的就是你的Storm。dir。在从属节点中也是如此，而主节点只是在Storm中更改路径。dirnimbus中的路径

更改（storm.local.dir:/home/ubuntu/storm/data）并且不要在supervisor和nimbus中使用相同的路径。
