nginx server_name 的反常理行为

TL;DR

It is important to understand that Nginx will only evaluate the server_name directive when it needs to distinguish between server blocks that match to the same level of specificity in the listen directive.

在全新安装了 Nginx 的机器上进行配置时，发现 server_name 这一配置失效：

某个 server 块中，配置有 server_name 和 location 块，而本地的 3000 端口运行着应用。*.internal 与 *.localhost 已在 DNS 记录中指向 127.0.0.1。：

server {
 listen 80;
 server_name sub.internal;

 location / {
 proxy_pass http://127.0.0.1:3000;
 }
}

在这一配置下，期望的行为是在访问 sub.internal 时被重定向到 127.0.0.1:3000，访问其他域名如 whatever.internal 或 whatever.localhost 时，无事发生。
