无法使用带 rails 的 dnsmasq 连接到本地服务器
Can not connect to local server using dnsmasq with rails
我有一个 rails 应用程序，我正尝试在 dnsmasq 的帮助下在本地环境中 运行。当我启动 rails 服务器时，它启动时没有显示任何错误：

如果我理解正确的话，您只有一台计算机（或虚拟机）带有开发环境 运行 Rails 应用程序和您的浏览器 window。所以你根本不需要dnsmasq，只需添加到你的/etc/hosts文件
127.0.0.1 www.example.dev
然后将浏览器指向 http://www.example.dev:3001 或 https://www.example.dev:3000，因为您配置了两个端口（3000 用于 ssl，3001 用于非 ssl 访问）- 查看 puma 启动消息.
更新
如你所愿dnsmasq:
- 文件
/etc/resolver/dev 应该只有一行（那里没有冒号！）
nameserver 127.0.0.1
- 似乎
dnsmasq 绑定到 127.0.0.53（请参阅 dnsmasq 状态消息底部的第三行），而不是 127.0.0.1
