一、安装:
1.安装rabbitmq运行环境
1)下载地址:https://www.erlang.org/downloads
2)下载完成之后,安装,直接下一步、下一步。
3)安装完成或,配置环境变量。
变量名:ERLANG_HOME
变量值:根据你安装的路径,如果都是下一步的话路径就是:C:\Program Files\erl-23.0
配置path路径:
2.安装rabbitmq。
1.下载地址:https://www.rabbitmq.com/download.html。
2)下载完成之后,安装,直接下一步、下一步。
3)进入安装路径,如果是直接下一步的话,路径是:C:\Program Files\RabbitMQ Server\rabbitmq_server-3.8.6\sbin
,执行rabbitmq-plugins enable rabbitmq_management
开启管理界面
4)启动。
点击右键,用管理员的身份运行。
5)然后再浏览器中输入:http://localhost:15672/#/exchanges
,地址,就可以看到如下界面了
6)输入rabbitmq的初始密码:Username:guest
,Password:guest
,就可以看到如下界面了:
7)rabbitmq登录进来,新建一个用户。
比如我新建的 Username:tianbin_test ,password:tianbin_test
8)选择标签(选Admin)
9)用户添加成功。
10)没有虚拟主机,新建一个虚拟主机
11)我这里填写的
12)添加成功的界面如下:
13)设置权限
14)查看权限
15)over。
二.rabbitmq的五种模式。
1.简单模式
说明:
1.生产者将消息交给默认的交换器(AMQP default)
2 .交换器获取消息后交给绑定这个生产者的队列(关系是通过队列名称完成)
3.监听当前队列的消费者获取消息,执行消费逻辑
使用:
1)使用tianbin_test用户登录。
2)设置权限
3).进入某个文件夹
在控制台中执行:composer init
然后再执行 :composer require php-amqplib/php-amqplib
代码结果如下:
新建文件夹和文件,最终结果如下:
[图片上传失败...(image-d2f1d-1597113673243)]
simple文件夹中customer文件内容如下:
channel();
$channel->queue_declare($exchange,false,false, false, false);
$callback = function ($msg) {
echo ' [x] Received ', $msg->body, "\n";
};
$channel->basic_consume($exchange, '', false, false, false, false, $callback);
while ($channel->is_consuming()) {
$channel->wait();
}
simple文件夹中producter文件内容如下:
channel();
$AMQPChannel->queue_declare($exchange,false,false, false, false);
$message = '简单模式';
$AMQPMessage = new AMQPMessage($message,array('content_type' => 'text/plain'));
$AMQPChannel->basic_publish($AMQPMessage,'',$exchange);
$AMQPChannel->close();
$connection->close();
执行:php producter.php
,结果如下:
执行:php customer.php
,结果如下:
备注:如果要手动进行消息确认(就是确定该消息有没有被消费成功)
请使用如下代码:
customer
代码如下
channel();
$channel->queue_declare($exchange,false,true, false, false);
$callback = function ($msg) {
echo ' [x] Received ', $msg->body, "\n";
//这里抛异常,该消息不会被消费
$msg->delivery_info['channel']->basic_ack($msg->delivery_info['delivery_tag']);
};
$channel->basic_consume($exchange, '', false, false, false, false, $callback);
while ($channel->is_consuming()) {
$channel->wait();
}
producter
代码如下
channel();
//$AMQPChannel->queue_declare($exchange,false,false, false, false);
$AMQPChannel->queue_declare($exchange,false,true, false, false);
$message = '简单模式';
$AMQPMessage = new AMQPMessage($message, array('delivery_mode' => AMQPMessage::DELIVERY_MODE_PERSISTENT));
$AMQPChannel->basic_publish($AMQPMessage,'',$exchange);
$AMQPChannel->close();
$connection->close();
演示:
1)执行:php producter.php
,结果如下:
2)修改customer
,结果如下:
3)执行
php customer.php
4)查看
5)结果如下:
7)如果我将异常去掉,执行
发现该消息已经被消费了。
2.工作模式
说明:
- 生产者将消息交个交换机
- 交换机交给绑定的队列
- 队列由多个消费者同时监听,只有其中一个能够获取这一条消息,形成了资源的争抢,谁的资源空闲大,争抢到的可能越大;
使用:
新建work目录和文件,最终目录结果如下
2)代码如下:
work文件夹producter的文件内容如下:
channel();
$AMQPChannel->queue_declare($exchange,false,true, false, false);
$message = '';
for ($i =0;$i<50;$i++){
$message= '工作模式'.(string)$i;
$AMQPMessage = new AMQPMessage($message,array('delivery_mode' => AMQPMessage::DELIVERY_MODE_PERSISTENT));
$AMQPChannel->basic_publish($AMQPMessage,'',$exchange);
}
$AMQPChannel->close();
$connection->close();
work文件夹customerOne的文件内容如下:
channel();
$channel->queue_declare($exchange, false, true, false, false);
$callback = function ($msg) {
echo ' [x] Received ', $msg->body, "\n";
echo " [x] Done\n";
sleep(10);
$msg->delivery_info['channel']->basic_ack($msg->delivery_info['delivery_tag']);
};
$channel->basic_consume($exchange, '', false, false, false, false, $callback);
while ($channel->is_consuming()) {
$channel->wait();
}
work文件夹customerTwo的文件内容如下:
channel();
$channel->queue_declare($exchange,false,true, false, false);
$callback = function ($msg) {
echo ' [x] Received ', $msg->body, "\n";
echo " [x] Done\n";
$msg->delivery_info['channel']->basic_ack($msg->delivery_info['delivery_tag']);
};
$channel->basic_consume($exchange, '', false, false, false, false, $callback);
while ($channel->is_consuming()) {
$channel->wait();
}
3)执行
php customerOne.php
php customerTwo.php
php producter.php
4)结果如下:
发现没有多劳多得。
6)修改代码
customerTwo的文件内容如下:
channel();
$channel->queue_declare($exchange,false,true, false, false);
$callback = function ($msg) {
echo ' [x] Received ', $msg->body, "\n";
echo " [x] Done\n";
$msg->delivery_info['channel']->basic_ack($msg->delivery_info['delivery_tag']);
};
$channel->basic_qos(null,1,null);//每个消费者只能处理一条信息
$channel->basic_consume($exchange, '', false, false, false, false, $callback);
while ($channel->is_consuming()) {
$channel->wait();
}
customerOne文件内容如下:
channel();
$channel->queue_declare($exchange, false, true, false, false);
$callback = function ($msg) {
echo ' [x] Received ', $msg->body, "\n";
echo " [x] Done\n";
sleep(10);
$msg->delivery_info['channel']->basic_ack($msg->delivery_info['delivery_tag']);
};
$channel->basic_qos(null,1,null);//每个消费者只能处理一条信息
$channel->basic_consume($exchange, '', false, false, false, false, $callback);
while ($channel->is_consuming()) {
$channel->wait();
}
7)执行
php customerOne.php
php customerTwo.php
php producter.php
8)结果如下:
9)over。
3.发布订阅模型
说明:
1 .生产者扔给交换机消息
2 .交换机根据自身的类型(fanout)将会把所有消息复制同步到所有与其绑定的队列
3 .每个队列可以有一个消费者,接收消息进行消费逻辑
使用:
1)新建fanout文件夹和文件,最终结构如下:
2)代码如下:
customerOne
文件内容如下:
channel();
$channel->exchange_declare($exchange, AMQPExchangeType::FANOUT, false, false, false);
list($queue_name, ,) = $channel->queue_declare($queue_name, false, false, true, false);
$channel->queue_bind($queue_name, $exchange);
$callback = function ($msg) {
echo ' [x] ', $msg->body, "\n";
};
$channel->basic_consume($queue_name, '', false, true, false, false, $callback);
while ($channel->is_consuming()) {
$channel->wait();
}
customerTwo
的文件内容如下:
channel();
$channel->exchange_declare($exchange, AMQPExchangeType::FANOUT, false, false, false);
list($queue_name, ,) = $channel->queue_declare($queue_name, false, false, true, false);
$channel->queue_bind($queue_name, $exchange);
$callback = function ($msg) {
echo ' [x] ', $msg->body, "\n";
};
$channel->basic_consume($queue_name, '', false, true, false, false, $callback);
while ($channel->is_consuming()) {
$channel->wait();
}
producter
文件内容如下:
channel();
$channel->exchange_declare($exchange, AMQPExchangeType::FANOUT, false, false, false);
list($queue_name, ,) = $channel->queue_declare($queue_name, false, false, true, false);
$channel->queue_bind($queue_name, $exchange);
$callback = function ($msg) {
echo ' [x] ', $msg->body, "\n";
};
$channel->basic_consume($queue_name, '', false, true, false, false, $callback);
while ($channel->is_consuming()) {
$channel->wait();
}
3)执行
php customerOne.php
php customerTwo.php
php producter.php
4)结果如下:
producter结果:
customerOne结果如下:
customerTwo结果如下:
4.路由模式
说明:
1.生产者还是将消息发送给交换机,消息携带具体的路由key(routingKey)
2.交换机类型direct,将接收到的消息中的routingKey,比对与之绑定的队列的routingKey
3.消费者监听一个队列,获取消息,执行消费逻辑
使用:
1)新建direct文文件夹和文件,最终结果如下:
2)代码如下:
customerOne
代码如下:
channel();
$channel->exchange_declare($exchange, AMQPExchangeType::FANOUT, false, false, false);
list($queue_name, ,) = $channel->queue_declare($queue_name, false, false, true, false);
$channel->queue_bind($queue_name, $exchange);
$callback = function ($msg) {
echo ' [x] ', $msg->body, "\n";
};
$channel->basic_consume($queue_name, '', false, true, false, false, $callback);
while ($channel->is_consuming()) {
$channel->wait();
}
customerTwo
代码如下:
channel();
$channel->exchange_declare($exchange, AMQPExchangeType::FANOUT, false, false, false);
list($queue_name, ,) = $channel->queue_declare($queue_name, false, false, true, false);
$channel->queue_bind($queue_name, $exchange);
$callback = function ($msg) {
echo ' [x] ', $msg->body, "\n";
};
$channel->basic_consume($queue_name, '', false, true, false, false, $callback);
while ($channel->is_consuming()) {
$channel->wait();
}
producter
代码如下:
channel();
$AMQPChannel->exchange_declare($exchange, AMQPExchangeType::FANOUT,false , false, false);
$message = 'fanout,hello';
$AMQPMessage = new AMQPMessage($message);
$AMQPChannel->basic_publish($AMQPMessage, $exchange);
echo ' [x] Sent ', $message, "\n";
$AMQPChannel->close();
$connection->close();
3)最终结果如下:
producter
如下:
customerTwo
如下:
customerOne
如下:
4)over。
5.主题 模式
说明:
1.生产端发送消息,消息携带具体的路由key
2 .交换机的类型topic
3 .队列绑定交换机不在使用具体的路由key而是一个范围值
*表示一个字符串(不能携带特殊符号)
表示任意字符串
使用:
1)新建topic文件夹和文件,最终结果如下:
2)代码如下:
customerOne
代码如下:
channel();
$binding_keys = [];
$binding_keys[] = '#';
$binding_keys[] = "*";
$channel->exchange_declare($exchange, AMQPExchangeType::TOPIC, false, false, false);
list($queue_name, ,) = $channel->queue_declare($queue_name, false, false, true, false);
foreach ($binding_keys as $binding_key) {
$channel->queue_bind($queue_name, $exchange, $binding_key);
}
$callback = function ($msg) {
echo ' [one] ', $msg->delivery_info['routing_key'], ':', $msg->body, "\n";
};
$channel->basic_consume($queue_name, '', false, true, false, false, $callback);
while ($channel->is_consuming()) {
$channel->wait();
}
customerTwo
代码如下:
`customerOne`代码如下:channel();
$binding_keys = [];
$binding_keys[] = 'insert.*';
$channel->exchange_declare($exchange, AMQPExchangeType::TOPIC, false, false, false);
list($queue_name, ,) = $channel->queue_declare($queue_name, false, false, true, false);
foreach ($binding_keys as $binding_key) {
$channel->queue_bind($queue_name, $exchange, $binding_key);
}
$callback = function ($msg) {
echo ' [one] ', $msg->delivery_info['routing_key'], ':', $msg->body, "\n";
};
$channel->basic_consume($queue_name, '', false, true, false, false, $callback);
while ($channel->is_consuming()) {
$channel->wait();
}
producter
代码如下:
channel();
$binding_keys = [];
$binding_keys[] = 'insert.*';
$channel->exchange_declare($exchange, AMQPExchangeType::TOPIC, false, false, false);
list($queue_name, ,) = $channel->queue_declare($queue_name, false, false, true, false);
foreach ($binding_keys as $binding_key) {
$channel->queue_bind($queue_name, $exchange, $binding_key);
}
$callback = function ($msg) {
echo ' [one] ', $msg->delivery_info['routing_key'], ':', $msg->body, "\n";
};
$channel->basic_consume($queue_name, '', false, true, false, false, $callback);
while ($channel->is_consuming()) {
$channel->wait();
}
3)最终结果如下:
producter
结果如下:
customerOne
结果如下:
customerTwo
结果如下:
