Apache Storm环境配置

I. 准备

apache-storm-0.9.3 zookeeper-3.4.6

II. 结构

一台server装nimbus和zookeeper，两台supervisor。

III. 配置

ZooKeeper：

# vi conf/zoo.cfg

clientPort=10205
server.0=nimbus:2888:3888

#vi /var/zookeeper/myid

<
与zoo.cfg中server.后面的数字一致，如nimbus机器改为0
>

Storm:

# vi conf/storm.yaml

storm.zookeeper.servers:
     - "nimbus"
     - "supervisor1"
     - "supervisor2"
     - "supervisor3"
storm.zookeeper.port: 10205
storm.local.dir: "/mnt/storm" #
表示storm需要用到的本地目录,
比如topology的jar文件保存，
java.library.path: /usr/local/lib:/opt/local/lib:/usr/lib
nimbus.host: "nimbus"
supervisor.slots.ports:  #
表示supervisor节点的槽数，即每个supervisor能开几个worker进程。
    - 6700
    - 6701
    - 6702
    - 6703

IV. 步骤

1.在nimbus上启动zookeeper。zk必须要先启动，否则nimbus启动会报错。

#./zkServer.sh start

JMX enabled by default
Using config: /root/storm/zookeeper-3.4.6/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED

# bin/zkCli.sh stat /测试服务是否正常启动

2.启动主节点nimbus和ui

nohup bin/storm nimbus &
nohup bin/storm ui &

3.启动从节点supervisor

nohup bin/storm supervisor &

4.查看界面：http://<nimbusIP>:18080/index.html

V. Example

这是storm安装包里提供的example，路径apache-storm-0.9.3\examples\storm-starter\src\jvm\storm\starter，提交一个topology命名为wordcountexample。
