      dnsmasq 是一个轻量级 DNS 和 DHCP 服务端，适合在家庭网络、小型办公网络或实验环境中统一管理内网域名解析和地址分配。

      启动

      启动脚本会准备容器和配置挂载目录。部署前先确认宿主机的 53/udp、53/tcp 和 DHCP 相关端口没有被其他服务占用。

      setup.sh
      #!/bin/bash

docker stop dnsmasq

      配置

      主配置集中在 dnsmasq.conf，常用配置包括上游 DNS、内网域名、固定主机解析、DHCP 地址池和静态租约目录。

      dnsmasq.conf
      # dnsmasq config, for a complete example, see:

# dhcp逻辑文件, 修改会自动重载
dhcp-hostsdir=/etc/dnsmasq/dhcp-hosts.d

# Dynamic range of IPs to make available to LAN pc
dhcp-range=10.32.9.2,10.32.9.254,255.255.240.0,12h

# If you’d like to have dnsmasq assign static IPs, bind the LAN computer's
# NIC MAC address:
dhcp-host=aa:bb:cc:dd:ee:ff,192.168.111.50
      Tip

      由于配置中设置了 dhcp-hostsdir，DHCP 静态租约可以放在 /etc/dnsmasq/dhcp-hosts.d，服务会自动重载。
