    参考文档：

    http://blog.csdn.net/historyasamirror/ar...

    依赖包安装

    yum install ncurses-devel unixODBC unixODBC-devel

    erlang环境

    wget http://erlang.org/download/otp_src_18.1.tar.gz
tar -zxvf otp_src_18.1.tar.gz
cd otp_src_18.1
./configure --prefix=/usr/local/erlang
make
make install


# 配置erlang环境变量
vim /etc/profile
# 增加内容：
export PATH="$PATH:/usr/local/erlang/bin"

# 保存退出，并刷新变量
source /etc/profile


# 测试erlang是否安装成功
# 安装完成以后，执行erl看是否能打开eshell，用’halt().’退出，注意后面的点号，那是erlang的结束符。
[root@localhost src]# erl 
Erlang/OTP 17 [erts-6.1] [source] [64-bit] [async-threads:10] [hipe] [kernel-poll:false]

Eshell V6.1  (abort with ^G) 
2> 9+3. 
12 
3> halt().

    安装rabbitmq依赖文件,安装rabbitmq

    # 安装rabbitmq依赖包
yum install xmlto

# 安装rabbitmq服务端
wget http://www.rabbitmq.com/releases/rabbitmq-server/v3.5.7/rabbitmq-server-3.5.7.tar.gz
tar zxvf rabbitmq-server-3.5.7.tar.gz
cd rabbitmq-server-3.5.7/
make
make install TARGET_DIR=/usr/local/rabbitmq SBIN_DIR=/usr/local/rabbitmq/sbin MAN_DIR=/usr/local/rabbitmq/man DOC_INSTALL_DIR=/usr/local/rabbitmq/doc

# 配置hosts
vim /etc/hosts
# 增加一行内容
# 当前IP地址   绑定HOSTNAME名称(vim /etc/sysconfig/network)
192.168.2.208 localhost.localdomain

# 这种会提示错误(Warning: PID file not written; -detached was passed.)
/usr/local/rabbitmq/sbin/rabbitmq-server -detached 启动rabbitmq
/usr/local/rabbitmq/sbin/rabbitmqctl status 查看状态
/usr/local/rabbitmq/sbin/rabbitmqctl stop 关闭rabbitmq

# 目前我自己使用
/usr/local/rabbitmq/sbin/rabbitmq-server start & 启动rabbitmq
/usr/local/rabbitmq/sbin/rabbitmqctl status 查看状态
/usr/local/rabbitmq/sbin/rabbitmqctl stop 关闭rabbitmq

    启用管理插件

    mkdir /etc/rabbitmq
/usr/local/rabbitmq/sbin/rabbitmq-plugins list 查看插件列表
/usr/local/rabbitmq/sbin/rabbitmq-plugins enable rabbitmq_management  (启用插件)
/usr/local/rabbitmq/sbin/rabbitmq-plugins disable rabbitmq_management (禁用插件)

# 重启rabbitmq
# 访问 http://127.0.0.1:15672/

# 如果有iptables
vim /etc/sysconfig/iptables

# 增加一下内容
-A INPUT -m state --state NEW -m tcp -p tcp --dport 15672 -j ACCEPT

# 重启动iptable
service iptables restart

    开机自启动配置

    #!/bin/sh
#start rabbitMq
sudo /usr/local/rabbitmq/sbin/rabbitmq-server & > /usr/local/rabbitmq/logs/rabbitmq.log 2>&1

    RabbitMQ PHP扩展安装

    # 安装rabbitmq-c依赖包
yum install libtool autoconf

# 安装rabbitmq-c ( 最好下载 0.5的，0.6安装可能会报错)
# 版本下载：https://github.com/alanxz/rabbitmq-c/releases/tag/v0.5.0
wget https://github.com/alanxz/rabbitmq-c/releases/download/v0.5.0/rabbitmq-c-0.5.0.tar.gz
tar -zxvf v0.5.0
cd rabbitmq-c-0.5.0/
autoreconf -i
./configure --prefix=/usr/local/rabbitmq-c
make
make install

# 安装PHP扩展 amqp
wget http://pecl.php.net/get/amqp-1.6.1.tgz
tar zxvf amqp-1.6.1.tgz
cd amqp-1.6.1
/usr/local/php/bin/phpize
./configure --with-php-config=/usr/local/php/bin/php-config --with-amqp --with-librabbitmq-dir=/usr/local/rabbitmq-c
make
make install

# 编辑php.ini文件，增加amqp扩展支持
vim /usr/local/php/etc/php.ini

# 增加下面内容
; rabbitmq扩展支持
extension=amqp.so

# 重启php-fpm
/etc/init.d/php-fpm restart

    验证是否成功 phpinfo()查看下是否支持amqp扩展

    相关配置

    hostname mq        // 设置hostname名称
vim /etc/sysconfig/network    // 设置hostname
vim /etc/hosts    // 编辑hosts
./rabbitmqctl add_user admin admin     // 添加用户
./rabbitmqctl set_user_tags admin administrator        // 添加admin 到 administrator分组
./rabbitmqctl set_permissions -p / admin "*." "*." "*."    // 添加权限

    创建配置文件

    #在/usr/rabbitmq/sbin/rabbitmq-defaults 查看config文件路径
# 创建配置文件 
touch/usr/rabbitmq/sbin
#vm_memory_high_watermark 内存低水位线，若低于该水位线，则开启流控机制,阻止所有请求，默认值是0.4，即内存总量的40%,
#vm_memory_high_watermark_paging_ratio 内存低水位线的多少百分比开始通过写入磁盘文件来释放内存
vi /usr/rabbitmq/sbin/rabbitmq.config 输入
[
{rabbit, [{vm_memory_high_watermark_paging_ratio, 0.75},
         {vm_memory_high_watermark, 0.7}]}
].

    创建环境文件

    touch /etc/rabbitmq/rabbitmq-env.conf
#输入
    RABBITMQ_NODENAME=FZTEC-240088 节点名称
    RABBITMQ_NODE_IP_ADDRESS=127.0.0.1 监听IP
    RABBITMQ_NODE_PORT=5672 监听端口
    RABBITMQ_LOG_BASE=/data/rabbitmq/log 日志目录
    RABBITMQ_PLUGINS_DIR=/data/rabbitmq/plugins 插件目录
    RABBITMQ_MNESIA_BASE=/data/rabbitmq/mnesia 后端存储目录

    操作命令

     查看exchange信息
          /usr/rabbitmq/sbin/rabbitmqctl list_exchanges name type durable auto_delete arguments

 查看队列信息
          /usr/rabbitmq/sbin/rabbitmqctl list_queues name durable auto_delete messages consumers me
  查看绑定信息
          /usr/rabbitmq/sbin/rabbitmqctl list_bindings
 查看连接信息
          /usr/rabbitmq/sbin/rabbitmqctl list_connections

    php的server端脚本

    <?php
$routingkey='key';
//设置你的连接
$conn_args = array('host' => 'localhost', 'port' => '5672', 'login' => 'guest', 'password' => 'guest');
$conn = new AMQPConnection($conn_args);
if ($conn->connect()) {
    echo "Established a connection to the broker \n";
}
else {
    echo "Cannot connect to the broker \n ";
}
//你的消息
$message = json_encode(array('Hello World3!','php3','c++3:'));
//创建channel
$channel = new AMQPChannel($conn);
//创建exchange
$ex = new AMQPExchange($channel);
$ex->setName('exchange');//创建名字
$ex->setType(AMQP_EX_TYPE_DIRECT);
$ex->setFlags(AMQP_DURABLE);
//$ex->setFlags(AMQP_AUTODELETE);
//echo "exchange status:".$ex->declare();
echo "exchange status:".$ex->declareExchange();
echo "\n";
for($i=0;$i<100;$i++){
        if($routingkey=='key2'){
                $routingkey='key';
        }else{
                $routingkey='key2';
        }
        $ex->publish($message,$routingkey);
}
/*
$ex->publish($message,$routingkey);
创建队列
$q = new AMQPQueue($channel);
设置队列名字 如果不存在则添加
$q->setName('queue');
$q->setFlags(AMQP_DURABLE | AMQP_AUTODELETE);
echo "queue status: ".$q->declare();
echo "\n";
echo 'queue bind: '.$q->bind('exchange','route.key');
将你的队列绑定到routingKey
echo "\n";

$channel->startTransaction();
echo "send: ".$ex->publish($message, 'route.key'); //将你的消息通过制定routingKey发送
$channel->commitTransaction();
$conn->disconnect();
*/

    php客户端脚本

    <?php
$bindingkey='key2';
//连接RabbitMQ
$conn_args = array( 'host'=>'127.0.0.1' , 'port'=> '5672', 'login'=>'guest' , 'password'=> 'guest','vhost' =>'/');
$conn = new AMQPConnection($conn_args);
$conn->connect();
//设置queue名称，使用exchange，绑定routingkey
$channel = new AMQPChannel($conn);
$q = new AMQPQueue($channel);
$q->setName('queue2');
$q->setFlags(AMQP_DURABLE);
$q->declare();
$q->bind('exchange',$bindingkey);
//消息获取
$messages = $q->get(AMQP_AUTOACK) ;
if ($messages){
var_dump(json_decode($messages->getBody(), true ));
}
$conn->disconnect();
?>

    翻译了部分mq常量设置,不正确的地方,大家以试验为准

    /**

/**
 * For exchanges, the auto delete flag indicates that the exchange will be deleted as soon as no more queues are bound
 * to it. If no queues were ever bound the exchange, the exchange will never be deleted. For queues, the auto delete
 * flag indicates that the queue will be deleted as soon as there are no more listeners subscribed to it. If no
 * subscription has ever been active, the queue will never be deleted. Note: Exclusive queues will always be
 * automatically deleted with the client disconnects.
 * 对交换机而言,自动删除标志表示交换机将在没有队列绑定的情况下被自动删除,如果从没有队列和其绑定过,这个交换机将不会被删除.
 * 对队列而言,自动删除标志表示如果没有消费者和你绑定的话将被自动删除,如果从没有消费者和其绑定,将不被删除,独占队列在客户断
