you need to install Storm's dependencies on Nimbus and the worker machines. These are:html
- Java 7+ (Apache Storm 1.x is tested through travis ci against both java 7 and java 8 JDKs)
- Python 2.6.6 (Python 3.x should work too, but is not tested as part of our CI enviornment)
按照官方文档 的说明:storm 运行依赖于 Java 7+ 和 Python 2.6.6 +,因此须要预先安装这两个软件。因为这两个软件在多个框架中都有依赖,其安装步骤单独整理至 :java
Linux 环境下 Python 安装github
下载并解压,官方下载地址:http://storm.apache.org/downloads.htmlshell
# tar -zxvf apache-storm-1.2.2.tar.gz
# vim /etc/profile
添加环境变量:apache
export STORM_HOME=/usr/app/apache-storm-1.2.2 export PATH=$STORM_HOME/bin:$PATH
使得配置的环境变量生效:vim
# source /etc/profile
由于要启动多个进程,因此统一采用后台进程的方式启动。进入到 ${STORM_HOME}/bin
目录下,依次执行下面的命令:app
# 启动zookeeper nohup sh storm dev-zookeeper & # 启动主节点 nimbus nohup sh storm nimbus & # 启动从节点 supervisor nohup sh storm supervisor & # 启动UI界面 ui nohup sh storm ui & # 启动日志查看服务 logviewer nohup sh storm logviewer &
验证方式一:jps 查看进程:框架
[root@hadoop001 app]# jps 1074 nimbus 1283 Supervisor 620 dev_zookeeper 1485 core 9630 logviewer
验证方式二: 访问 8080 端口,查看 Web-UI 界面:oop
