　　官方地址：http://www.rabbitmq.com/
　　PHP扩展包：http://pecl.php.net/package/amqp
　　1. 安装RabbitMQ  (unbuntu)
sudo apt-get install rabbitmq-server 
sudo /etc/init.d/rabbitmq-server start
　　2. 安装librabbitmq  (unbuntu)
sudo apt-get install mercurial 
hg clone http://hg.rabbitmq.com/rabbitmq-c 
cd rabbitmq-c 
hg clone http://hg.rabbitmq.com/rabbitmq-codegen codegen 
autoreconf -i && ./configure && make && sudo make install 
 
3. 安装php-rabbit扩展  (unbuntu)
wget http://php-rabbit.googlecode.com/files/php-rabbit.r91.tar.gz 
tar -zxvf php-rabbit.r91.tar.gz 
cd php-rabbit.r91 
/path/to/php/bin/phpize 
./configure –with-amqp –with-php-config=/path/to/php/bin/php-config 
make && sudo make install 
编辑 php.ini 添加： 
extension=rabbit.so 
输出phpinfo看下是否扩展已经加载成功 (window apache下安装要注意同时在apache 配置文件中加载LoadFile "D:/xampp/php/rabbitmq.1.dll")
　　4. 代码实例
　　发送消息：

<?php
error_reporting(E_ERROR);
set_time_limit(0);
$exchangeName = 'demo';
$queueName = 'hello';
$routeKey = 'hello';
$message = 'Hello World!';
$connection = new AMQPConnection(array('host' => '127.0.0.1', 'port' => '5672', 'vhost' => '/', 'login' => 'guest', 'password' => 'guest'));
$connection->connect() or die("Cannot connect to the broker!\n");
try {
$channel = new AMQPChannel($connection);
$exchange = new AMQPExchange($channel);
$exchange->setName($exchangeName);
$queue = new AMQPQueue($channel);
$queue->setName($queueName);
$i = 0;
while ($i < 100) {
$message = $i .':'. date("Y-m-d H:i:s") ;
$exchange->publish($message, $routeKey);
$i +=1;
}
var_dump("[x] Sent 'Hello World!'");
} catch (AMQPConnectionException $e) {
var_dump($e);
exit();
}
$connection->disconnect();
?>
　　处理消息队列

<?php
error_reporting(E_ERROR);
set_time_limit(0);
$exchangeName = 'demo';
$queueName = 'hello';
$routeKey = 'hello';
$connection = new AMQPConnection(array('host' => '127.0.0.1', 'port' => '5672', 'vhost' => '/', 'login' => 'guest', 'password' => 'guest'));
$connection->connect() or die("Cannot connect to the broker!\n");
$channel = new AMQPChannel($connection);
$exchange = new AMQPExchange($channel);
$exchange->setName($exchangeName);
$exchange->setType(AMQP_EX_TYPE_DIRECT);
$exchange->declare();
$queue = new AMQPQueue($channel);
$queue->setName($queueName);
$queue->declare();
$queue->bind($exchangeName, $routeKey);
var_dump('

Waiting for messages. To exit press CTRL+C');
while (TRUE) {
$queue->consume('callback');
}
$connection->disconnect();
function callback($envelope, $queue) {
$msg = $envelope->getBody();
var_dump(" Received:" . $msg);
$queue->nack($envelope->getDeliveryTag());
}
