192.168.49.18:7001 is not configured as a cluster node. [root@localhost cluster]# CLUSTER NODES

The error message suggests that the IP address and port 192.168.49.18:7001 is not configured as a cluster node in your cluster.

To resolve this issue, you should add the node to the cluster by using the `CLUSTER MEET` command. For example, if you have another node with IP address 192.168.49.19 and port 7001, you can add it to the cluster by running the following command on one of the existing nodes:

CLUSTER MEET 192.168.49.19 7001

After running this command, you can check the status of your nodes by running the `CLUSTER NODES` command again.

java.lang.IllegalStateException: RabbitTemplate is not configured as MessageListener - cannot use a 'replyAddress': reply_queue

这个错误信息是在Java中使用RabbitMQ（一个开源的消息队列系统）时遇到的问题，特别是当你试图通过`RabbitTemplate`发送消息并期望得到回复时发生的。`IllegalStateException`表明操作违反了RabbitTemplate的配置，它需要被设置为MessageListener才能处理接收响应。

通常，当我们在RabbitMQ中设置一个`replyTo`字段（即`replyQueue`），意味着我们期待一个来自特定交换机的确认或应答消息。然而，如果`RabbitTemplate`没有被正确配置为监听者（MessageListener），也就是说，它没有注册回调函数来接收和处理这些响应消息，那么尝试使用`replyTo`就会抛出这个异常。

要解决这个问题，你需要确保：

1. **配置RabbitTemplate**: 在应用启动时，你需要初始化RabbitTemplate，并将其设置为MessageListener模式，例如，通过`@RabbitListener`注解或者直接在模板上设置监听器。

@Bean
public RabbitTemplate rabbitTemplate() {
    RabbitTemplate template = new RabbitTemplate(rabbitConnectionFactory());
    // 配置模板为MessageListener
    template.setMessageConverter(converter);
    return template;
}

// 或者使用RabbitListener
@RabbitListener(queues = "requestQueue")
public void handleRequest(String request, Channel channel) {
    // 处理请求并回应
}

2. **检查监听器绑定**: 确保你的生产者（发送消息的消费者）和消费者之间的消息路由规则已经正确配置，包括`exchange`, `routingKey`, 和 `queue` 的关联。

3. **处理异常**: 如果在生产者代码中，确保对这种异常有适当的处理，比如记录日志或者抛出更友好的异常给用户。

msedge.exe *64 - 192.168.1.1:53 DNS-UDP Error:QTYPE is incorrect

This error message indicates that there is a problem with the DNS resolution process for the Microsoft Edge browser. Specifically, the QTYPE (query type) parameter that Edge is sending to the DNS server at 192.168.1.1 is incorrect. This could be due to a configuration issue with the browser or the DNS server, or it could be caused by a network connectivity problem.

To troubleshoot this issue, you can try the following steps:

1. Check your network connectivity: Make sure that your computer is connected to the network and that you can access other websites and resources without issue.

2. Check your DNS settings: Verify that the DNS server address configured on your computer is correct and that it is reachable. You may need to check with your network administrator or Internet service provider to ensure that you have the correct DNS server settings.

3. Clear your browser cache and cookies: Sometimes, browser cache and cookies can cause issues with DNS resolution. Try clearing your browser cache and cookies and then restarting the browser.

4. Try using a different browser: If the problem persists, try using a different browser to see if the issue is specific to Microsoft Edge.

If none of these steps resolve the issue, you may need to contact Microsoft support or your network administrator for further assistance.
