请问下在linux环境下 goblog.com 需要加端口是怎么回事？

centos-stream 没用过。

检查 80 端口是否是被 Nginx 使用，有些时候系统会默认启用 httpd（Apache），也是占用了 80 端口。

如果 80 端口被占用 nginx应该开启不了才是，目前可以访问到 nginx默认页面

这里我还有一个疑问：

nginx 默认配置是这种形式的

include /etc/nginx/conf.d/*.conf; 文件形式是：goblog.com.conf

include /etc/nginx/sites-enabled/*; goblog.com

吃过多次亏，你这个页面看不出来是 nginx 界面，要确定一下：

netstat -nlp | grep 80

配置问题的话，自己调试一下，手头上没有 centos-stream ，不知道默认安装的配置是咋样的。

这是查看端口和nginx展示的图片。

nginx 完整配置文件：

#user  nobody;
worker_processes  1;
#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;


events {
    worker_connections  1024;
}


http {
include       mime.types;
default_type  application/octet-stream;

#log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
#                  '$status $body_bytes_sent "$http_referer" '
#                  '"$http_user_agent" "$http_x_forwarded_for"';

#access_log  logs/access.log  main;

sendfile        on;
#tcp_nopush     on;

#keepalive_timeout  0;
keepalive_timeout  65;

#gzip  on;

server {
        listen       80;
        server_name  localhost;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location / {
            root   html;
            index  index.html index.htm;
        }

        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
    }
    include /etc/nginx/sites-enabled/*.conf;
}

这个是 goblog.com 配置

hosts文件

刚刚又测试了一下

在nginx日志看到这一条
