macos - 为什么 nginx 运行在 8080 端口而不是 81 端口？

问题描述

根据brew info nginx终端输出告诉我nginx默认情况下在端口 8080 上运行：

/usr/local/etc/nginx/nginx.conf 中的默认端口已设置为 8080，以便 nginx 无需 sudo 即可运行。

这是完整的输出：

$ brew info nginx
nginx: stable 1.19.0 (bottled), HEAD
HTTP(S) server and reverse proxy, and IMAP/POP3 proxy server
https://nginx.org/
/usr/local/Cellar/nginx/1.19.0 (25 files, 2.1MB) *

From: https://github.com/Homebrew/homebrew-core/blob/master/Formula/nginx.rb
==> Dependencies
Required: openssl@1.1 ✔, pcre ✔
==> Options
--HEAD
    Install HEAD version
==> Caveats
Docroot is: /usr/local/var/www

The default port has been set in /usr/local/etc/nginx/nginx.conf to 8080 so that
nginx can run without sudo.

nginx will load all files in /usr/local/etc/nginx/servers/.

To have launchd start nginx now and restart at login:
  brew services start nginx
Or, if you don't want/need a background service you can just run:
  nginx

install-on-request: 33,387 (30 days), 99,128 (90 days), 394,576 (365 days)
build-error: 0 (30 days)

我的 Mac OS 是 Catalina 10.15

但是，当我查看nginx.confin时，/usr/local/etc/nginx/nginx.conf我没有看到 nginx 端口在 8080 上打开。我看到它在端口 81 上打开：

server {
        listen       81;
        server_name  localhost;
    ....
    ....

当我去访问时，http://localhost:8080/我会收到 nginx 欢迎消息。但是，当我去访问时，http://localhost:81/我收到“无法访问站点”ERR_CONNECTION_REFUSED错误。

8080如果文件中没有这样的规范，nginx 如何在端口上运行nginx.conf？以及为什么nginx 没有81在 conf 似乎建议的端口上运行。

这是完整的nginx.conf：
