我认为我将其范围缩小为"groonga".首先，我听说过它，但显然这是对mariadb brew的依赖.我发现欢迎使用nginx"在哪里文字来自.

I think I narrowed it down to "groonga." First I'm hearing of it, but apparently it's a mariadb brew dependency. I found where the "welcome to nginx" text was coming from.

var/www/index.html

如果文本也会在apache运行时显示，则不确定为什么要对该文本进行硬编码.非常混乱.但是，它将文件添加到默认的Apache DocumentRoot中.

Not sure why it's hard coding that text if it will also display with apache running. Very confusing. However, it adds that file to the default apache DocumentRoot.
