队列笔记

1： 列出队列（Listing queues）

如果你想查看Rabbitmq队列，并且想知道有多少消息存在其中，你(作为特权用户)可以使用rabbitmqctl 工具：

rabbitmqctl list_queues。

在Windows中，省略sudo：

rabbitmqctl.bat list_queues

2： 工作队列

我们发现即使使用CTRL+C杀掉了一个工作者（worker）进程，消息也不会丢失。当工作者（worker）挂掉这后，所有没有响应的消息都会重新发送。

一个很容易犯的错误就是忘了basic_ack，后果很严重。消息在你的程序退出之后就会重新发送，如果它不能够释放没响应的消息，RabbitMQ就会占用越来越多的内存。

为了排除这种错误，你可以使用rabbitmqctl命令，输出messages_unacknowledged字段：

$ sudo rabbitmqctl list_queues name messages_ready messages_unacknowledged

在window系统运行，去掉sudo：

$ rabbitmqctl.bat list_queues name messages_ready messages_unacknowledged

3: rabbitmqctl能够列出服务器上所有的交换器：

$ sudo rabbitmqctl list_exchanges

这个列表中有一些叫做amq.*的交换器。这些都是默认创建的，不过这时候你还不需要使用他们。

4:列出所有现存的绑定

rabbitmqctl list_bindings

5: 如果你想把日志保存到文件中，只需要打开控制台输入： ( ​​receive_logs.php​​ 源代码)

$ php receive_logs.php > logs_from_rabbit.log

如果你希望所有的日志信息都输出到屏幕中，打开一个新的终端，然后输入：

$ php receive_logs_direct.php info warning error
# => [*] Waiting for logs. To exit press CTRL+C

如果要触发一个error级别的日志，只需要输入：

$ php emit_log_direct.php error "Run. Run. Or it will explode."
# => [x] Sent 'error':'Run. Run. Or it will explode.'

队列安装

第一：安装RabbitMq环境

​​windows环境的rabbitmq安装与启动​​

​​https://my.oschina.net/owenzhang24/blog/5051652​​

第二：

composer require php-amqplib/php-amqplib

第三:代码类

  1. rabbitMq实现的基础类：application/common/lib/classes/rabbitmq/RabbitMq.php
  2. 供外部调用的rabbitMq类：application/common/lib/classes/RabbitMqWork.php
  3. 测试发送消息到rabbitMq中的方法：application/index/controller/Index.php
  4. 添加php think命令实现接收rabbitMq中的消息：application/common/command/*.php

第四:使用说明

  1. 发送消息时直接在自己的方法中调用RabbitMqWork.php类中的几个送消息的方法即可。
  2. application/common/command/下的类都是实现添加php think命令的类，在configure方法中的setName()中设置命令名称，execute()方法是为了执行接收rabbitMq中的消息，同时在application/command.php中return添加设置的命令名称及对应的命令目录地址。
  3. 贡献文档
  4. ​​RabbitMQ 中文文档－PHP版​​​。​​https://xiaoxiami.gitbook.io/rabbitmq_into_chinese_php/​​
  5. ​​RabbitMQ官方文档​​​。​​https://www.rabbitmq.com/getstarted.html​​
