Goal
次のことをやる。- RabbitMQをUbuntuインストールする(12.04)
- サンプルRubyクライントを動かす
- Web管理画面を動かす
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. RabbitMQをUbuntuにインストールする
RabbitMQをインストールするにはaptのソースリストに１つ追加する必要がある。以下のコマンドでapt-getを使ってRabbitMQをインストールしてみる。
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 ...

2. サンプルRubyクライントを動かす
サンプルRubyクライアントを動かしてみる。RubyでRabbitMQを扱うにはbunnyというライブラリを使うと楽。
まずはGemfileを書く。
次はコード。source "https://rubygems.org" gem "bunny", ">= 1.7.0"
#!/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
動いてる。bundle install ===== Fetching gem metadata from https://rubygems.org/... Resolving dependencies...

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! =====
3. Web管理画面を動かす
RabbitMQでは各種プラグインが使える。管理画面もそのプラグインの一つ。
以下のコマンドでプラグインを有効にできる。
sudo rabbitmq-plugins list
=====
