After installing nginx, I set the owner of sbin/nginx to root and suid permissions to monitor port 80.

chown root sbin/nginx chmod u+s sbin/nginx

But after startup, when accessing localhost port 80, an error is reported: 403 Forbidden

nginx related configuration file contents are as follows:

server { listen 80; server_name localhost; #charset koi8-r; charset utf-8; #access_log logs/host.access.log main; location / { root html; index index.html index.htm; } #error_page 404 /404.html; # redirect server error pages to the static page /50x.html # error_page 500 502 503 504 /50x.html; location = /50x.html { root html; }

The error log information is:

[error] 4633#0: *1 open() "nginx/html/favicon.ico" failed (13: Permission denied), client: 127.0.0.1, server: localhost, request: "GET /favicon.ico HTTP/1.1", host: "localhost", referrer: "http://localhost/"

The permissions of the html directory are as follows, and there is a corresponding index file in this directory

drwxrwxrwx@ 4 xxxxx staff 136 Nov 16 21:16 html

Excuse me, what is the problem? Baidu later said it was a permissions issue, but I can’t fix it no matter how I change it?
My system is mac.
