环境：Rails 5.2.3, Macos
一、字体文件 production 上无法加载，dev 环境正常
直接下载了个 fontawesome-free 的压缩包，包含了 css、js、和 webfonts，加入到工程中 assets.rb 中如下
Rails.application.config.assets.paths << Rails.root.join("vendor", "fontawesome-free","css")
Rails.application.config.assets.paths << Rails.root.join("vendor", "fontawesome-free","js")
Rails.application.config.assets.paths << Rails.root.join("vendor", "fontawesome-free", "webfonts")
......
Rails.application.config.assets.precompile << /\.(?:otf|svg|eot|woff|ttf|woff2)\z/
然后看 public 下其实预编译的资源文件已存在，但是就是提示无法下载，然而把 fontawesome-free/webfonts 下的文件拷贝到 public 下就可以了，一脸茫然。
二、nginx+puma production log 一直报这个错误，是啥原因，google 也没相关信息

第一个的问题可能原因是你用 assets pipeline 的时候在 css 里怎么引用字体的，需要用 asset_url 来引用，而不能直接使用路径
第二个应该是你代码写矬了 他也说清楚了 找不到 [GET] "/monitor/alive"，检查你路由定义

🙏第一个解答
第二个问题就是很挫，没有地方用到这个路由，也不知道是哪里用到的，后台固定间隔会报这个错，但和实际业务没有影响。。就是看着 log 很烦人。

第二个问题有两种可能，首先，Ruby 对于路由不匹配都会报这个，这里有两种可能，一种是有人在扫描你，另一种，你可以这样排查，就是对你部署好的代码（连同预编译好的 Assets）用报错的 /monitor/alive 去做文本检索，看看是哪里搞出来的。不过看 url 的样子，像是某种监控软件定期监听心跳导致的，你也可以查查看
