Problem on API server connects RPC server.

[freeFesei]

rpc 端已经连接到了 etcd 中 etcd 的版本是 3.5.4

但是 api 去连接的时候报错

2024/07/27 20:27:18 rpc dial: etcd://localhost:2379/user.rpc, error: context deadline exceeded, make sure rpc service “user.rpc” is already started

你的服务监听的是 192.168.10.3, 如果你在同一台机器上尝试通过 localhost 或 127.0.0.1 连接这个服务，默认情况下是不行的。 原因： localhost 和 127.0.0.1 是指向回环接口的特殊地址。 当服务绑定到特定 IP 地址时，它只监听那个特定的网络接口。 回环接口和实际的网络接口是分开的。 解决方法： 如果你希望服务既能通过具体 IP 访问，又能通过 localhost 访问，你可以：修改服务配置，使其监听 0.0.0.0:8080 这将使服务监听所有可用的网络接口，包括回环接口。

Your service is listening on 192.168.10.3. If you try to connect to this service through localhost or 127.0.0.1 on the same machine, it will not work by default. reason: localhost and 127.0.0.1 are special addresses that point to the loopback interface. When a service is bound to a specific IP address, it only listens on that specific network interface. The loopback interface is separate from the actual network interface. Solution: If you want the service to be accessible both through a specific IP and through localhost, you can: Modify the service configuration so that it listens on 0.0.0.0:8080 This will cause the service to listen on all available network interfaces, including the loopback interface.

为什么感觉怪怪的，etcd作为服务注册，对于服务192.168.10.3:8080 返回客户端去连接，客户端 不就可以去连接了吗？

Why does it feel weird? etcd is registered as a service. For the service 192.168.10.3:8080, it returns to the client to connect. Can the client connect?
