问题 I want to know who to adjust quantity of the socket descriptors? In addition, how to auto-close the connection for limited timeout? 回答1: Looks like you have to change max opened file descriptors in your system. From RabbitMQ installation manual for Debian and Ubuntu systems, section Controlling system limits: RabbitMQ installations running production workloads may need system limits and kernel parameters tuning in order to handle a decent number of concurrent connections and queues.

Introduction RabbitMQ is a message broker: it accepts and forwards messages. You can think about it as a post office: when you put the mail that you want posting in a post box, you can be sure that Mr. or Ms. Mailperson will eventually deliver the mail to your recipient. In this analogy, RabbitMQ is a post box, a post office and a postman. RabbitMQ是一个消息中转器,它接收并转发消息。你可以把它看成是一个邮局:当你放了一封你要寄出的信到邮箱里时,你可以肯定邮递员先生或女士最终会把信交给你的收件人。在这个类比中,RabbitMQ充当了邮箱,邮局以及邮递员的角色。 The major difference between RabbitMQ and the post office is that it doesn't deal with paper, instead it accepts, stores and forwards binary

Why can't you look at messages in the Rabbit Queue

流过昼夜 提交于 2020-01-11 18:06:28
问题 If my understanding is correct, you can't actually look at messages in the rabbit queue without taking them out and putting them back in. There's no way to use rabbitmqctl to inspect a queue. In some debugging contexts, knowing what is currently in the queue is very useful. Is there a way to get at the messages? Also, what is it about the design of Rabbit that makes this process cumbersome? 回答1: I have not used this personally yet but I saw RabbitMQ's management plugin that I thought allowed

RabbitMQ学习一环境搭建

别来无恙 提交于 2020-01-11 08:02:25
RabbitMq学习一环境搭建 一、下载及安装 (一)访问官网并进行下载https://www.rabbitmq.com RabbitMq基于Erlang开发因此还需下载和安装Mq的运行环境Erlang,注意Mq的版本要与Erlang相匹配,版本相兼容信息可在Mq官网查阅 (二)安装 先安装Erlang再安装Mq默认都是下一步直至结束。 再安装RabbitMq默认下一步直到结束。 下载地址:https://pan.baidu.com/s/1QWM8ZhuFE5hS1CMaWdAehw 经过测试新版本下安装可以直接访问RabbitMq的UI控制界面 http://localhost:15672 默认用户名和密码都是guest 二、在MQ中UI控制界面中进行用户管理 (一)创建用户 以超管身份登录http://localhost:15672选择Admin功能页进行用户的新增 (二)virtual hosts virtual hosts就相当于数据库(mySql的DB),只有给用户进行了授权那么用户才能进行访问和使用数据库 进行virtual hosts的创建,创建中一般以“/”进行开头 (三)对用户进行授权 (四)MQ中UI界面相关功能的介绍 实际开发中使用代码控制和操作mq,使用的就是amqp通信协议 来源: CSDN 作者: 平凡一哥 链接: https://blog.csdn

问题 I've installed RabbitMQ 3.5.5 on Windows Server 2012 as a service by first installing Erlang (32 bit) and then following the RabbitMQ manual install instructions (https://www.rabbitmq.com/install-windows-manual.html) The Windows service starts up fine, but nothing can connect.

How to make RabbitMQ scalable?

扶醉桌前 提交于 2020-01-11 05:38:09
问题 I tried to test RabbitMQ, but I found that rabbitmq has some problems: if I created a cluster of 3 nodes, I can't publish/delivered more than 6000/s. in other hand, if I worked with one single node, I can publish/delivery until 25000/s. which means, more that I add nodes, more performance is deteriorating. but from this article : https://blog.pivotal.io/pivotal/products/rabbitmq-hits-one-million-messages-per-second-on-google-compute-engine they can publish more than 1 million, so how they can
