安装 Avahi

sudo apt-get install avahi-daemon

一旦配置完成，你的树莓派就可以通过 raspberrypi.local 这样的地址被网络中的其他设备发现.其中 hostname 是你的树莓派的实际主机名。这样，你的 ESP8266 就可以使用 mDNS 协议发现树莓派的 IP 地址了

安装 avahi-tools

安装之后，才能使用 avahi-browse 命令。

可以查看局域网内所有的mdns服务，命令如下：

# Ubuntu / Debian

$ sudo apt install avahi-daemon avahi-utils

查看局域网内所有的mdns服务

avahi-browse -a

output

ping raspberrypi.local

Avahi 是一个免费的零配置网络（zeroconf）实现，包括一个用于组播 DNS/DNS-SD 服务发现的系统。它允许程序发布和发现在本地网络上运行的服务和主机，而无需特定配置。比如，traefik.local、homepage.local就可以轻松实现。

苹果的Bonjour服务（mDNS）通过使用.local后缀，实现了多址广播域名的设备识别。

avahi-tools 软件包包括许多方便的实用程序，可用于检查系统上的 mDNS 服务的工作情况。比如：

# 查看局域网内所有已注册的 mDNS 服务

  $ avahi-browse -a -r

    # 发现某个类型的服务的返回包

  $ avahi-browse -r "xxx"

-xxx 是指服务类型，如_http._tcp
