管理MQ（WEB页面）

新增用户

给新增的用户授权

启动报错

org.springframework.amqp.AmqpIOException: java.io.IOException….

问题原因

 解决方法（给rabbitmq新增的用户授权）

1.打开RabbitMq web管理界面，进入该页面，点击用户名称

2.点击 set premission 按钮，就ok了

再去本地启动一下项目，使用这个用户。发现不报错了。

删除队列

        开发的过程中，有些事件会因为代码的不完善消费失败，然后就会一直消费，然后一直报错。当bug修复，把正确的代码上传到开发环境，原先遗留的问题消息任然存在，并且会阻塞队列，让之后的正常的消息无法让系统正常的消费。

法1：通过网页删除（消息多时会报错）

访问网址：http://localhost:15672

找到指定队列

在下方的 Delete / Purge 中点击 Delete 或者是 Purge 都可以达到效果（delete：删除消息与队列；purge：只删消息）

缺点：消息多的时候点击，页面会卡死。即使没有卡死也会出现如下对话框：

网上也没有搜索到什么有用的答案。只找到一句话，来自：https://blog.csdn.net/u011973...

如果队列的主节点不可用，则非镜像队列的行为取决于其持久性。在节点恢复正常之前，持久化队列将不可用。在集群中其他节点上对主节点不可用的持久化队列进行任何操作都将失败

法2：重置RabbitMQ

rabbitmqctl stop_app
rabbitmqctl reset
rabbitmqctl start_app

执行了一次之后确实是有效的。重启的RabbitMq，然后里面的消息也确实清空了。

缺点：不仅会清空消息，还会清空所有配置信息。

法3：命令删除指定的队列

下边三个都可以

rabbitmqctl purge_queue ${queue_name} 
rabbitmqctl purge_queue ${queue_name}
rabbitmqctl -p ${vhostpath} purge_queue ${queue_name} 

也可以使用rabbitmqadmin

rabbitmqadmin delete queue name='queuename'

rabbitmqctl

简介

在windows下使用rabbitmqadmin 比较麻烦，需要用python运行，例如：python rabbitmqadmin list users。

rabbitmqadmin使用方法

以下步骤的前提是管理插件management pluin已安装好

1. 在浏览器中输入 (“server-name”为你rabbitmq的hostname)

http://server-name:15672/cli/    //本机使用默认的localhost，在浏览器中输入http://localhost:15672/cli/

2. 按照页面提示，右键保存下载链接，浏览器会下载rabbitmqadmin文件，并且自动加上后缀名txt，这个rabbitmqadmin.txt其实是一个python内容的文件，所以需要用python解析，确保你电脑有python2.x，不支持3.x。

3. 将rabbitmqadmin.txt放到和python.exe同个路径，并把后缀txt去掉，然后通过下面的方式去调用rabbitmqadmin

python.exe rabbitmqadmin

4. 使用下面的命令可以查看使用说明

python.exe rabbitmqadmin --help
基本功能和网页版插件一样，包括：
- 查看exchanges, queues, bindings, vhosts, users, permissions, connections和channels.
- overview信息查看
- 声明，删除exchanges, queues, bindings, vhosts, users 和 permissions
- 发布或获取消息
- 关闭连接，释放队列
- 导入导出配置

5. rabbitmqadmin支持bash shell用tab键自动补齐，查看bash自动补齐脚本可以调用一下命令

python.exe rabbitmqadmin --bash-completion

命令
