其他笔记：
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.'
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
rabbitMq实现的基础类：application/common/lib/classes/rabbitmq/RabbitMq.php
供外部调用的rabbitMq类：application/common/lib/classes/RabbitMqWork.php
测试发送消息到rabbitMq中的方法：application/index/controller/Index.php
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
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。
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。
