you need to install Storm's dependencies on Nimbus and the worker machines. These are:
- 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 +,所以需要预先安装这两个软件。由于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 :
下载并解压,官方下载地址:http://storm.apache.org/downloads.html
# tar -zxvf apache-storm-1.2.2.tar.gz
# vim /etc/profile
添加环境变量:
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:
# source /etc/profile
因为要启动多个进程,所以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:
# 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:
[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:
