Goal

Do following:

  1. Install RabbitMQ in Ubuntu(12.04)
  2. Run sample ruby client
  3. Run Web UI

Environment

  • OS
    • Linux version 3.2.0-64-generic (buildd@kissel) (gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5) ) #97-Ubuntu SMP Wed Jun 4 22:04:21 UTC 2014
  • RabbitMQ
    • 3.5
  • ruby
    • 2.1.2p95

Procedure

1. Install RabbitMQ in Ubuntu

We need to add one line to source list.
Following command add one line to source list, add signature to apt, install with apt-get install and check running status.

sudo vim /etc/apt/sources.list.d/rabbitmq.list
=====
deb http://www.rabbitmq.com/debian/ testing main
=====

# Add signature
wget http://www.rabbitmq.com/rabbitmq-signing-key-public.asc
sudo apt-key add rabbitmq-signing-key-public.asc

# apt-get
sudo apt-get update
sudo apt-get install rabbitmq-server

# Check status
sudo /etc/init.d/rabbitmq-server status
=====
Status of node rabbit@www1242up ...

 {running_applications,[{rabbit,"RabbitMQ","3.5.0"},
                        {mnesia,"MNESIA  CXC 138 12","4.5"},

=====

2. Run sample ruby client

bunny allows us to write client code easily.
At first I’ll write Gemfile.

source "https://rubygems.org"

gem "bunny", ">= 1.7.0"

Next is client code.

#!/usr/bin/env ruby
# encoding: utf-8

require "rubygems"
require "bunny"

conn = Bunny.new
conn.start

ch = conn.create_channel
q  = ch.queue("bunny.examples.hello_world", :auto_delete => true)
x  = ch.default_exchange

q.subscribe do |delivery_info, metadata, payload|
  puts "Received #{payload}"
end

x.publish("Hello!", :routing_key => q.name)

sleep 1.0
conn.close

Let’s run the client with following command.

bundle install
=====
Fetching gem metadata from https://rubygems.org/...
Resolving dependencies...
Installing amq-protocol 1.9.2
Installing bunny 1.7.0
Using bundler 1.7.4
Your bundle is complete!
Use `bundle show [gemname]` to see where a bundled gem is installed.
=====

ls
=====
client.rb  Gemfile  Gemfile.lock
=====

bundle exec ruby client.rb
=====
Received Hello!
=====

It looks work.

3. Run management screen(Web UI)

RabbitMQ can use plugins.
Management screen is one of the plugins.
I’ll enable the plugin with following commands.

sudo rabbitmq-plugins list
=====
