I have a nginx.conf that looks like this
server {
listen 3000;
server_name ~^(?<sub>.+)\.localhost$;
root www/$sub;
}
And www/hello/index.html contains only hello world text.
The idea is http://hello.localhost will be served from www/hello directory. Using system-wide nginx works fine, however, when I run nginx in nix-shell, I get 500 error without any more error message.
nix-shell -p nginx --run "nginx -p . -c nginx.conf"
# or
nix-shell -I nixpkgs=http://github.com/NixOS/nixpkgs/archive/e199c174c69f196301de2ad2d5d87c76a822a558.tar.gz -p nginx --run "nginx -p . -c nginx.conf"
% curl hello.localhost:3000
<html>
<head><title>500 Internal Server Error</title></head>
<body>
<center><h1>500 Internal Server Error</h1></center>

sudo nginx -p . -c nginx.conf
% curl hello.localhost:3000
hello world
