ubuntu 12.04安装配置rabbitmq
在安装rabbitmq之前，需要先安装一些依赖关系，比如erlang，下面介绍安装方法：
一. 安装erlang
1.安装依赖关系包
sudo apt-get install build-essential libncurses5-dev m4 libssl-dev unixodbc unixodbc-dev libc6 freeglut3-dev libwxgtk2.8-dev xsltproc fop g++ build-essential
2.下载源码包
wget https://packages.erlang-solutions.com/erlang/esl-erlang/FLAVOUR_1_general/esl-erlang_19.1-2~ubuntu~precise_i386.deb
3.安装
sudo dpkg -i esl-erlang_19.1-2~ubuntu~precise_i386.deb
4.验证安装成功
erl
输出如下信息：
Erlang /OTP19 (erts-8.1) [source-77fb4f8] [async-threads:10] [hipe] [kernel-poll:false]Eshell V8.1 (abort with ^G)1>
二. 安装rabbitmq-server
1.下载安装包
wget http://www.rabbitmq.com/releases/rabbitmq-server/v3.4.3/rabbitmq-server_3.4.3-1_all.deb
2.安装
sudo dpkg -i rabbitmq-server_3.4.3-1_all.deb
3.重启rabbitmq-server服务
sudo /etc/init.d/rabbitmq-server restart
4.查看rabbitmq服务
ps -ef |grep rabbitmq
5.rabbitmq web管理页面插件安装
rabbitmq-plugins enable rabbitmq_management
安装完成后即可通过 进行访问。
三. 安装setuptools
1.下载安装包
wget http://pypi.python.org/packages/source/s/setuptools/setuptools-0.6c11.tar.gz
2.解压
tar -zxvf setuptools-0.6c11.tar.gz
3.进入setuptools-0.6c11源目录
cd setuptools-0.6c11
4.编译
python setup.py build
5.安装
python setup.py install
四. 安装AMQP python客户端pika
1.下载安装包
wget https://pypi.python.org/packages/source/p/pika/pika-0.9.14.tar.gz#md5=b99aad4b88961d3c7e4876b8327fc97c
2.解压
tar zxvf pika-0.9.14.tar.gz
3.安装
python setup.py install
五. 测试实例
采用最简单的情况作为实例，发送消息，接收并打印出来即可。如下图所示：
#!/usr/bin/env python import pika # 1. Establish a connection with RabbitMQ server. connection = pika.BlockingConnection(pika.ConnectionParameters( 'localhost')) channel = connection.channel() # 2. Create a queue to which the message will be delivered, let's name it 'hello' channel.queue_declare(queue='hello') # 3. Use a default exchange identified by an empty string, which allows us to specify # exactly to which queue the message should go. The queue name needs to be specified # in the routing_key parameter: channel.basic_publish(exchange='', routing_key='hello', body='Hello World!') print " [x] Sent 'Hello World!'" # 4. Close the connection connection.close()
recv.py
#!/usr/bin/env python import pika # 1. Establish a connection with RabbitMQ server connection = pika.BlockingConnection(pika.ConnectionParameters( host='localhost')) channel = connection.channel() # 2. Make sure that the queue exists,run the command as many times as we like, and only one will be created. channel.queue_declare(queue='hello') print ' [*] Waiting for messages. To exit press CTRL+C' # 3. Define a callback function.Whenever we receive a message, # this callback function is called by the Pika library. def callback(ch, method, properties, body): print " [x] Received %r" % (body,) # 4. Subscribe the callback function to a queue. # Tell RabbitMQ that this particular callback function should receive messages from our hello queue. channel.basic_consume(callback, queue='hello', no_ack=True) # 5. Enter a never-ending loop that waits for data and runs callbacks whenever necessary. channel.start_consuming()
测试结果
python send.py——>[x] Sent 'Hello World!'python recv.py——>[*] Waiting for messages. To exit press CTRL+C [x] Received 'Hello World!' [x] Done
