Here we will learn how to setup or install Erlang and RabbitMQ on windows machines and how to enable RabbitMQ web management plugin in step by step manner.
The RabbitMQ is built on Erlang runtime environment so before we install RabbitMQ, first we need to download and install Erlang in our machines.
Rabbitmq Server Download For Mac Download
What is Erlang?
Erlang is a general-purpose programming language and runtime environment.
Erlang has built-in support for concurrency, distribution and fault tolerance. Erlang is used in several large telecommunication systems from Ericsson.
Erlang Installation
Following is the link to download and install Erlang on your windows machine.
Once you open above URL, select a required version to download and install on your machines like as shown following.
After downloading the required Erlang version, now we will install Erlang for that double click on downloaded install file and follow the instructions like as shown below.
RabbitMQ Installation
After completion of Erlang installation, now we will install RabbitMQ on windows for that download a RabbitMQ setup file from following link for windows.
After opening the above URL, we will get a RabbitMQ setup files information like as shown below. Here we are going to install a RabbitMQ server on windows machine so we will download the windows version like as shown below.

After downloading the required setup file, just double click on setup file to install rabbitmq on windows like as shown below.
Starting RabbitMQ Server
After completion of installing the RabbitMQ server, we will check the status of RabbitMQ server for that search for RabbitMQ Command Prompt and open it with admin privilege like as shown below.
After opening the command prompt, enter command “rabbitmqctl status” and click enter to check the status of RabbitMQ server.
In case, if it shows an error like as below, then you need to follow the given steps to fix this error.
RabbitMQ Authentication Failed Error
Following are the steps to fix an error like “Authentication failed (rejected by the remote node), check the Erlang cookie”.
- In file explorer navigate to your user directory by pasting %userprofile% in your address bar.
- In case if already .erlang.cookie file available in that location, just delete it otherwise go to the next step.
- In a second File Explorer, navigate to C:WindowsSystem32configsystemprofile.
- Find the file .erlang.cookie and copy it to your user directory.
- Now your rabbitmqctl should be able to authenticate.
After completion of above steps, then again run “rabbitmqctl status” command in rabbitmq command prompt as an administrator, then it will shows the screen like as shown below.
Now, we are done with starting the RabbitMQ server, next we will enable a web management plugin for RabbitMQ.

RabbitMQ Enable Web Management Plugin
To enable a rabbitmq web management plugin on windows, we need to start RabbitMQ Command Prompt with administrator privilege, enter the command “rabbitmq-plugins enable rabbitmq_management” and execute it.
After executing the above web management command, the web management plugins will be enabled and it will show the plugins list which are enabled.
Now you can open web management plugin in the browser for that enter the following URL in browser and click enter.
After opening the localhost URL in browser, it will ask you for credentials to access web management plugin.
To access rabbitmq web management dashboard, the default Username and password of is “guest” (Username: “guest” | Password: “guest”).
After login with default credentials, the following overview screen will appear.
Now we have successfully started the RabbitMQ server and web management plugin.
In next chapters, we will learn about the available components of RabbitMQ such as Exchanges, Queues, Channels, etc with examples.
The Apache Hadoop software library is a framework that allows for the distributed processing of large data sets across clusters of computers using simple programming models. It is designed to scale up from single servers to thousands of machines, each offering local computation and storage. Rather than rely on hardware to deliver high-availability, the library itself is designed to detect and handle failures at the application layer, so delivering a highly-available service on top of a cluster of computers, each of which may be prone to failures.

Flume is a distributed, reliable and available service for efficiently collecting, aggregating, and moving large amounts of log data. It has a simple and flexible architecture based on streaming data flows. It is robust and fault tolerant with tunable reliability mechanisms and many failover and recovery mechanisms. It uses a simple extensible data model that allows for online analytic application.

This tutorial describes how to store data in the Hadoop Distributed File System (HDFS) using a Hortonworks Single Node Data Platform (HDP). The HDP is a Hortonworks Sandbox hosted on a VirtualBox VM. In addition, the Sandbox includes management tools to enable you to view and manage the data.
This tutorial describes how to
- Download and setup VirtualBox on MAC OSX
- Import Hortonworks Sandbox as a VM
- Install Maven to build open source Java packages
- Setup a RabbitMQ Server as an Event Source for Flume
- Setup Flume to consume messages from RabbitMQ and
sink
the data to HDFS - Run a simple NodeJS RabbitMQ Producer to generate messages and route them to RabbitMQ
- Use HADOOP tools to
manage
data stored in HDFS 1. HCatalog – a table and storage management layer – http://hortonworks.com/hadoop/hcatalog/2. Hive – facilitates querying and managing large datasets – see https://hive.apache.org/ 3. Use the Hortonworks Management tools to manage the data
Download and setup VirtualBox
- Download VirtualBox for Mac OS X http://www.oracle.com/technetwork/server-storage/virtualbox/downloads/index.html
- Run the downloaded
dmg
package - Setup network adapters
Import Hortonworks Sandbox 2.1
- Download the Hortonworks OVA from http://hortonworks.com/products/hortonworks-sandbox/#install
- Follow the instructions in http://hortonworks.com/wp-content/uploads/2014/04/InstallingHortonworksSandbox2_1MacUsingVB.pdf
- Start the VirtualBox
- Logon to VirtualBox from the Terminal Window
Fn+Alt+F5
and get its “external” IP Address - ssh to the VirtualBox

Create a virtual host
Enable administration of the Virtual Host from Management Console
Start RabbitMQ as a background process
Test the RabbitMQ Management console
A Flume dataflow consists of configuring a source, a sink and a channel. In this tutorial, the source consists of a RabbitMQ Server and the sink is the HDFS file system. The data flow works as follows
- The source consumes events delivered to it by RabbitMQ using the
RabbitMQ-Flume Plugin
- When the Flume source receives an event, it stores it into one or more channels. The channel is a passive store that keeps the event until it’s consumed by a Flume sink
- The sink removes the event from the channel and stores the data in HDFS (via Flume HDFS sink)
- The source and sink within the given agent run asynchronously with the events staged in the channel.
Install Flume
Install the RabbitMQ-Flume Plugin
Configure Flume to source from Rabbit and sink to HDFS
Setup a Flume source to consumer messages from RabbitMQ and sync the data to HDFS.
edit/create /etc/flume/conf/analytics.conf and enter the following
Start the flume service as a background process
Rabbitmq Download
View the Data
Create a Hive Table to access the HDFS data. The LOCATION value is the path specified in the HDFS sink
analytics.sinks.sink_to_hdfs.hdfs.path
in $FLUME_HOME/conf/analytics.confUse the Hortonworks Management console to view the list of tables, you should now see a table called
analytics
Install and run the NodeJS Message Producer
If you do not have NodeJS installed, checkout http://shapeshed.com/setting-up-nodejs-and-npm-on-mac-osx for instructions
On your MAC, checkout the code from git.
Edit etc/vars.env – this script setups ENV variables to connect to the RabbitMQ Server on the Hortonworks Sandbox and sepcifies the queue to be created and the Virtual host to access.
When configured, source the ENV variables as follows
Run the NodeJS script. The script connects to the RabbitMQ Server (specified in the
RABBIT_SERVER Environment Variable
), creates a queue (specified in the RABBIT_QUEUE Environment Variable
) and produces messages.The Flume service consumes the messages and stores them in HDFS.
View Flume Processing
You can view Flume processing progress by viewing the logs as follows
