rabbitmq源码安装和配置

1. 安装rabbitmq 之前首先

(1)安装erlang.:

下载erlang:

1. 从Erlang的官网 http://www.erlang.org/download.html 下载最新的erlang安装包，Linux和MacOSX下载的版本是R15B01 Source File(72.0 MB)
2. 我的是Mac OSX系统 所以我直接在 http://www.erlang-solutions.com/section/132/download-erlang-otp下载的对应版本的安装包，省的自己配置和安装了
3. 然后解压下载的gz包 tar zxcf *.tar.gz
4. cd 进入解压出来的文件夹
5. 执行./configure --prefix=/opt/erlang 就会开始编译安装 会编译到 /opt/erlang 下 然后执行
6. make 和 make install
7. 编译完成以后，进入/opt/erlang，输入erl测试erlang是否安装成功。
8. 修改/etc/profile文件，增加下面的环境变量：
9. #set erlang environment
10. export PATH=$PATH:/opt/erlang/bin
11. source profile使得文件生效

或者：

yum install erlang

(2）.安装python

yum install python -y

(3) 安装simplejson

yum -y install xmlto

yum -y install python-simplejson

(4)安装rabbitmq
1.下载：
 # wget http://www.rabbitmq.com/releases/rabbitmq-server/v3.4.2/rabbitmq-server-generic-unix-3.4.2.tar.gz
2.解压缩：
 # tar -zxf rabbitmq-server-generic-unix-3.4.2.tar.gz
3.移动这个目录到 /usr/local下并且重命名为rabbitmq:
 # mv rabbitmq-server-generic-unix-3.4.2 /usr/local/rabbitmq
4.打开/etc/profile文件，在文件最后添如下两行环境变量
   #set rabbitmq environment
   export PATH=$PATH:/usr/local/rabbitmq/sbin
5.使环境变量生效:
 # source /etc/profile
6.安装rabbitmq网页管理插件：
 # cd /usr/local/rabbitmq/sbin/
 #./rabbitmq-plugin enable rabbitmq-management
7.启动rabbitmq:
 # cd /usr/local/rabbitmq/sbin
 # ./rabbitmq-server -detached (可以实现后台运行)
8.查看启动是否成功: # netstat -tunlp | grep beam
 tcp 0 0 0.0.0.0:25672 0.0.0.0:* LISTEN 3308/beam.smp
 tcp 0 0 0.0.0.0:15672 0.0.0.0:* LISTEN 3308/beam.smp
 tcp 0 0 :::5672 :::* LISTEN 3308/beam.smp
可以看到启动成功: 15672是rabbimq网页管理监听端口,5672是php客户端使用的端口，在浏览器中输入localhost:15672，可以看到如下页面：
输入用户名guest和密码guest即可通过网页管理rabbitmq。
 9. 关闭rabbitmq ： # cd /usr/local/rabbitmq/sbin 然后：#./rabbitmqctl stop

(5)php客户端使用rabbitmq

composer是PHP用来管理依赖（dependency）关系的工具。你可以在自己的项目中声明所依赖的外部工具库（libraries），Composer 会帮你安装这些依赖的库文件,具体可参考composer权威网站：http://www.phpcomposer.com/

1）下载 Composer 的可执行文件# curl -sS https://getcomposer.org/installer | php# chmod u+x composer.phar# mv composer.phar /usr/local/bin/composer2）声明php依赖关系 在php项目下创建 composer.json 文件，描述了项目的依赖关系。

{
"reqire": {
"videlalvaro/php-amqplib": "v2.1.0"
}
}

3.使用 Composer

在与composer.json文件相同的目录下运行如下代码:

  # composer install

4.这时候在composer.json相同的目录下生成vendor目录，这个目录中是composer.json文件中指定的php依赖库下载后的放置位置。
  # ls
amqp                 index.php           receive_logs.php         vendor
Application          new_task.php        receive_logs_topic.php   worker.php
composer.json        phpinfo.php         send.php
emit_log_direct.php  Public              test.php
emit_log.php         README.md           ThinkPHP

以上就搭建好了php和rabbitmq的使用环境，下面是怎么使用php作为客户端和rabbitmq通信。

再读这几篇文章:http://blog.youkuaiyun.com/wind_324/article/category/2165209


在官网介绍hello world这篇文章时候send.php和receive.php代码可能有错误，这时候，可以从刚才根据composer.json文件生成的依赖库vendor/videlalvaro/php-amqplib/demo目录下找到amqp_publisher.php和amqp_consumer.php这两个demo文件，复制到/usr/local/apache/htdocs目录下，不要使用官网上的send.php和receive.php文件。
打开 amqp_publisher.php文件进行修改，修改后的代码如下：

<?php
include(__DIR__ . '/vendor/autoload.php');
use PhpAmqpLib\Connection\AMQPConnection;
use PhpAmqpLib\Message\AMQPMessage;
define('HOST', '127.0.0.1');
define('PORT', 5672);
define('USER', 'guest');
define('PASS', 'guest');
define('VHOST', '/');
$exchange = 'router';
$queue = 'msgs';
$conn = new AMQPConnection(HOST, PORT, USER, PASS, VHOST);
$ch = $conn->channel();
/*
    The following code is the same both in the consumer and the producer.
    In this way we are sure we always have a queue to consume from and an
        exchange where to publish messages.
*/
/*
    name: $queue
    passive: false
    durable: true // the queue will survive server restarts
    exclusive: false // the queue can be accessed in other channels
    auto_delete: false //the queue won't be deleted once the channel is closed.
*/
$ch->queue_declare($queue, false, true, false, false);
/*
    name: $exchange
    type: direct
    passive: false
    durable: true // the exchange will survive server restarts
    auto_delete: false //the exchange won't be deleted once the channel is closed.
*/
$ch->exchange_declare($exchange, 'direct', false, true, false);
$ch->queue_bind($queue, $exchange);
$msg_body = implode(' ', array_slice($argv, 1));
$msg = new AMQPMessage($msg_body, array('content_type' => 'text/plain', 'delivery_mode' => 2));
$ch->basic_publish($msg, $exchange);
$ch->close();
$conn->close();

amqp_consumer.php进行修改后的代码：

<?php
include(__DIR__ . '/vendor/autoload.php');
use PhpAmqpLib\Connection\AMQPConnection;
define('HOST', '127.0.0.1');
define('PORT', 5672);
define('USER', 'guest');
define('PASS', 'guest');
define('VHOST', '/');
$exchange = 'router';
$queue = 'msgs';
$consumer_tag = 'consumer';
$conn = new AMQPConnection(HOST, PORT, USER, PASS, VHOST);
$ch = $conn->channel();
/*
    The following code is the same both in the consumer and the producer.
    In this way we are sure we always have a queue to consume from and an
        exchange where to publish messages.
*/
/*
    name: $queue
    passive: false
    durable: true // the queue will survive server restarts
    exclusive: false // the queue can be accessed in other channels
    auto_delete: false //the queue won't be deleted once the channel is closed.
*/
$ch->queue_declare($queue, false, true, false, false);

/*
    name: $exchange
    type: direct
    passive: false
    durable: true // the exchange will survive server restarts
    auto_delete: false //the exchange won't be deleted once the channel is closed.
*/
$ch->exchange_declare($exchange, 'direct', false, true, false);
$ch->queue_bind($queue, $exchange);
function process_message($msg)
{
    echo "\n--------\n";
    echo $msg->body;
    echo "\n--------\n";

<pre name="code" class="php">    $msg->delivery_info['channel']->
        basic_ack($msg->delivery_info['delivery_tag']);

    // Send a message with the string "quit" to cancel the consumer.
    if ($msg->body === 'quit') {
        $msg->delivery_info['channel']->
            basic_cancel($msg->delivery_info['consumer_tag']);
    }
}

/*
    queue: Queue from where to get the messages
    consumer_tag: Consumer identifier
    no_local: Don't receive messages published by this consumer.
    no_ack: Tells the server if the consumer will acknowledge the messages.
    exclusive: Request exclusive consumer access, meaning only this consumer can access the queue
    nowait:
    callback: A PHP Callback
*/

$ch->basic_consume($queue, $consumer_tag, false, false, false, false, 'process_message');

function shutdown($ch, $conn)
{
    $ch->close();
    $conn->close();
}
register_shutdown_function('shutdown', $ch, $conn);

// Loop as long as the channel has callbacks registered

while (count($ch->callbacks)) {
    $ch->wait();
}

 

测试 一下：

打开消费者监听：
[root@ip10 htdocs]# php amqp_consumer.php

发布者发布消息：
[root@ip10 htdocs]# php amqp_publisher.php 'lsi';
[root@ip10 htdocs]# php amqp_publisher.php 'zhangsan'

可以看到监听者打印出了这两个消息：
[root@ip10 htdocs]# php amqp_consumer.php

--------
lsi
--------

--------
zhangsan
--------

在localhost:15672 网页管理系统中可以看到有个msgs的队列（刚才创建的），并且在messages中看到total为2，因为我们刚才发布的两条消息，所以在这个队列中有2个消息。
