Storm源码阅读（一）：使用_info (backtype.storm.stormsubmitter:120)

Storm项目主页http://storm-project.net/，github主页https://github.com/nathanmarz/storm

storm源码是clojure和java的混合体

安装JRE

Clojure 运行在 JRE (JAVA Runtime Environment) 之上，因此，你需要先安装 JRE。

安装lein

Clojure项目管理工具：Leiningen，类似于maven。leiningen使用maven仓库进行包管理

http://leiningen-win-installer.djpowell.net/

lein基本操作

$ lein new [TEMPLATE] NAME # generate a new projectskeleton

$ lein test [TESTS] # run the tests in the TESTSnamespaces, or all tests

$ lein repl # launch an interactive REPL session

$ lein run -m my.namespace # run the -main function of anamespace

$ lein uberjar # package the project and dependencies asstandalone jar

$ lein deps //下载依赖到storm/lib

$ lein compile //编译生成storm.jar

$ lein install //安装到本地.m2库

$ lein version //查看version版本

$ lein uberjar //生成一个适合提交给storm集群的jar包

$ lein pom //生成pom.xml

类似pom文件，工程根目录下的 project.clj 内容类似

(defproject myproject"0.5.0-SNAPSHOT"

  :description"A project for doing things."

  :license"Eclipse Public License 1.0"

  :url"http://github.com/technomancy/myproject"

  :dependencies [[org.clojure/clojure"1.5.1"]]

  :plugins [[lein-ring"0.4.5"]])

Lein pom命令：根据project.clj生成pom.xml，导入eclipse。

安装

zeromq

$ wgethttp://download.zeromq.org/zeromq-2.1.7.tar.gz

$ tar -xzf zeromq-2.1.7.tar.gz

$ cdzeromq-2.1.7

$ ./configure

$ make

$ sudo make install

jzmq

$git clone https://github.com/nathanmarz/jzmq.git

$cd jzmq

$./autogen.sh

$./configure

$make

$sudo make install

Zookeeper配置

#zoo.cfg

server.1=192.168.119.24:5888:6888

server.2=192.168.119.25:5888:6888

server.3=192.168.119.26:5888:6888

storm配置

#storm.yaml

storm.zookeeper.servers:

- "192.168.119.24"

- "192.168.119.25"

- "192.168.119.26"

storm.zookeeper.port: 5181

nimbus.host: "192.168.119.24"

启动storm

storm nimbus #24

storm ui #24

storm supervisor #24, 25, 26

http://192.168.119.24:8080

生产环境使用supervisord保证出错退出时重启

storm-starter

storm-starters提供了storm的使用例子。如果不研究storm的实现，只是使用，可以直接按照storm-starter的例子编写代码。

$ git clone git@github.com:nathanmarz/storm-starter.git

$ cdstorm-starter

$ lein deps

$ lein compile

$ lein uberjar

$./storm jar storm-starter-0.0.1-SNAPSHOT-standalone.jarstorm.starter.ExclamationTopology exclamation-topology

需要在客户端机器上配置 ~/.storm/storm.yaml

[root@localhost bin]# mkdir ~/.storm

[root@localhost bin]# cp../conf/storm.yaml ~/.storm/storm.yaml
