创建rabbitMQ容器并运行

docker run -d --hostname my-rabbit --name Myrabbitmq -e RABBITMQ_DEFAULT_USER=admin -e RABBITMQ_DEFAULT_PASS=admin -p 15672:15672 -p 5672:5672 rabbitmq:3-management

说明:

-d 后台运行容器;

–name 指定容器名;

-p 指定服务运行的端口(5672:应用访问端口;15672:控制台Web端口号);

-v 映射目录或文件;

–hostname 主机名(RabbitMQ的一个重要注意事项是它根据所谓的 “节点名称” 存储数据,默认为主机名);

-e 指定环境变量;(RABBITMQ_DEFAULT_VHOST:默认虚拟机名;RABBITMQ_DEFAULT_USER:默认的用户名;RABBITMQ_DEFAULT_PASS:默认用户名的密码)

PHP安装扩展AMQP

1、安装rabbitmq-c,rabbitmq-c是一个用于C语言的,与AMQP server进行交互的client库。

下载地址:https://github.com/alanxz/rabbitmq-c

unzip rabbitmq-c-master.zip
cd rabbitmq-c-master
sudo mkdir /opt/rabbitmq-c
sudo mkdir build && cd build
sudo cmake -DCMAKE_INSTALL_PREFIX=/opt/rabbitmq-c ..
sudo cmake --build .
sudo make
sudo make install

2、从https://pecl.php.net/package/amqp下载 amqp-1.9.4.tgz

wget https://pecl.php.net/get/amqp-1.9.4.tgz
tar -zxvf amqp-1.9.4.tgz
cd amqp-1.9.4
/usr/bin/phpize
./configure --with-php-config=/usr/bin/php-config --with-amqp --with-librabbitmq-dir=/opt/rabbitmq-c
make && make install

可能报错:
/usr/bin/ld: cannot find -lrabbitmq
collect2: error: ld returned 1 exit status
make: *** [amqp.la] Error 1
解决:yum install librabbitmq-devel
解决:apt install librabbitmq-dev

结果:

tsing@ubuntu:~/package/amqp-1.9.4$ sudo make install
Installing shared extensions:     /usr/lib/php/20160303/

3、然后在php.ini添加 extension=amqp.so,然后执行/php -m|grep amqp,看列出的已安装扩展是否存在amqp。

extension=amqp.so #extension_dir自己定义

cli/php.ini 与 fpm/php.ini 都要添加,使得命令行及CGI模式下都支持amqp模块

4、验证

命令行模式:php -m |grep amqp

CGI模式通过访问PHPinfo()函数确认,页面上会显示amqp的的compiled时间。

生产者demo

<?php
//配置信息 
$conn_args = array( 
    'host' => '192.168.8.130',  
    'port' => '5672',  
    'login' => 'guest',  
    'password' => 'guest', 
    'vhost'=>'/' 
);   
$e_name = 'e_jm'; //交换机名 
$q_name = 'q_jm'; //无需队列名 
$k_route = 'key_jm'; //路由key 
 
//创建连接和channel 
$conn = new AMQPConnection($conn_args);   
if (!$conn->connect()) {   
    die("无法连接,中断!\n");   
}   
$channel = new AMQPChannel($conn);   
 

 
//创建交换机对象    
$ex = new AMQPExchange($channel);   
$ex->setName($e_name);   
date_default_timezone_set("Asia/Shanghai");
//发送消息 
//$channel->startTransaction(); //开始事务  
for($i=0; $i<100; ++$i){ 
    sleep(1);//休眠1秒
    //消息内容 
    $message = "测试消息:".date("Y-m-d H:i:s");   
    echo "发送消息:".$ex->publish($message, $k_route)."\n";  
} 
//$channel->commitTransaction(); //提交事务 
 
$conn->disconnect();
?>

消费者demo

<?php 
//配置信息 
$conn_args = array( 
    'host' => '192.168.8.130',  
    'port' => '5672',  
    'login' => 'guest',  
    'password' => 'guest', 
    'vhost'=>'/' 
);   
$e_name = 'e_jm'; //交换机名 
$q_name = 'q_jm'; //队列名 
$k_route = 'key_jm'; //路由key 
 
//创建连接和channel 
$conn = new AMQPConnection($conn_args);   
if (!$conn->connect()) {   
    die("无法连接,中断!\n");   
}   
$channel = new AMQPChannel($conn);   
 
//创建交换机    
$ex = new AMQPExchange($channel);   
$ex->setName($e_name); 
$ex->setType(AMQP_EX_TYPE_DIRECT); //direct类型  
$ex->setFlags(AMQP_DURABLE); //持久化 
echo "交换机状态:".$ex->declare()."\n";   
   
//创建队列    
$q = new AMQPQueue($channel); 
$q->setName($q_name);   
$q->setFlags(AMQP_DURABLE); //持久化  
echo "消息总数:".$q->declare()."\n";   
 
//绑定交换机与队列,并指定路由键 
echo '队列绑定: '.$q->bind($e_name, $k_route)."\n"; 
 
//阻塞模式接收消息 
echo "消息:\n";   
while(True){ 
    $q->consume('processMessage');   
    //$q->consume('processMessage', AMQP_AUTOACK); //自动ACK应答  
} 
$conn->disconnect();   
 
/**
 * 消费回调函数
 * 处理消息
 */ 
function processMessage($envelope, $queue) { 
    $msg = $envelope->getBody(); 
    echo $msg."\n"; //处理消息 
    $queue->ack($envelope->getDeliveryTag()); //手动发送ACK应答 
}
?>

demo执行

注:cli/php.ini一定要加amqp.so扩展,在命令行下才支持AMQP相关类及方法

先执行消费者脚本接收消息:

php -f rabbit_consumer.php

再生产消息:

php -f rabbit_publisher.php
