# RabbitMQ设置

{% hint style="info" %}
及时获悉最准确和最新硬件建议，请参考[RabbitMQ官方文档](https://www.rabbitmq.com/docs/production-checklist)。
{% endhint %}

对于生产系统，建议使用具有[仲裁队列](https://bbs.huaweicloud.com/blogs/364672) (quorum queues) 的多节点RabbitMQ集群，以确保消息的耐用性和高可用性。这种设置可提高容错能力和性能，从而构建可靠的消息传递基础设施。

### 硬件要求

* CPU：多核处理器
* 内存：单个节点至少 4GB
* 硬盘：建议使用SSD硬盘，以获得更好的性能
* 网络：高速、低延迟的网络连接

### 安装RabbitMQ

遵循[RabbitMQ官方安装文档](https://www.rabbitmq.com/docs/download#installation-guides)要求，选择合适你操作系统的安装流程。

### 添加RabbitMQ凭证

1. **启用RabbitMQ管理面板**

```
sudo rabbitmq-plugins enable rabbitmq_management
```

2. **为RabbitMQ创建管理员用户**

{% hint style="info" %}
服务器稍后将使用这些确切的凭证连接到队列。
{% endhint %}

```
sudo rabbitmqctl add_user <admin> <password>
sudo rabbitmqctl set_user_tags <admin> <administrator>
sudo rabbitmqctl set_permissions -p / <admin> ".*" ".*" ".*"
```

你可以自定义`<admin>` (管理员用户名)、 `<password>`(密码)。

3. **访问RabbitMQ管理面板**

在浏览器打开：<http://localhost:15672>，导航到`default`，RabbitMQ的默认管理面板。

使用用户名`<admin>`和上一步中设置的密码`<password>`登录管理面板。

### 服务器监控

可通过[Prometheus Blackbox Exporter](https://github.com/prometheus/blackbox_exporter)轮询RabbitMQ服务器的可用性。

RabbitMQ特定的Prometheus指标也可以通过任何开源[Prometheus RabbitMQ导出器](https://github.com/kbudde/rabbitmq_exporter)来公开。
