+# Storm单机版本环境搭建
+
+### 1. 安装环境要求
+
+> you need to install Storm's dependencies on Nimbus and the worker machines. These are:
+>
+> 1. Java 7+ (Apache Storm 1.x is tested through travis ci against both java 7 and java 8 JDKs)
+> 2. 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](http://storm.apache.org/releases/1.2.2/Setting-up-a-Storm-cluster.html)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  ：
+
++ [Linux环境下JDK安装](https://github.com/heibaiying/BigData-Notes/blob/master/notes/installation/Linux下JDK安装.md)
+
++ [Linux环境下Python安装](https://github.com/heibaiying/BigData-Notes/blob/master/notes/installation/Linux下Python安装.md)
+
+  
+
+### 2. 下载并解压
+
+下载并解压，官方下载地址：http://storm.apache.org/downloads.html 
+
+```shell
+# tar -zxvf apache-storm-1.2.2.tar.gz
+```
+
+### 3. 配置环境变量
+
+```shell
+# vim /etc/profile
+```
+
+添加环境变量：
+
+```shell
+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：
+
+```shell
+# source /etc/profile
+```
+
+
+
+### 4. 启动相关进程
+
+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：
+
+```shell
+# 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 &
+```
+
+
+
+### 5. 验证是否启动成功
+
+验证方式一：jps 查看进程：
+
+```shell
+[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：
